BRK 86RAC Smoke Detector Replacement and Additions

I have two BRK 86RAC Ionisation type smoke detector, one in the Hall and the other on the upstairs Landing, these were installed by the builder and in 2008 I added a heat detector (690MBX) in the garage, all three devices are mains powered with battery backup and are interlinked so that they all alert to a detection.

BRK 86RAC Discontinued ionisation smoke detector.

Checking the batteries in the smoke detector I noticed the unit has a life of 10 years from date of manufacture which was 21 June 2002, as the date of noticing this was 4 March 2018, they are well overdue for replacement!

The BRK 86RAC is no longer produced and has been replaced by the  BRK 670MBX.

brk

Checking my local Screwfix had BRK ionisation smoke dectors (part number 81969) for £12.99 and the surface mounting kit (part number 30152) for £2.99, I thought I would add two more to my system, so bought  four of everything.

On opening the boxes, I didn’t realise that the detectors came with 9v PP3 type batteries, so wasted £6.00 buying them, and the other thing was that they are not a direct replacement, the 86RAC base is a smaller size and the plugin connector is a different style.

In the box are the above plus instructions, sticker for the consumer unit and protective detector cover, no fixing screws are supplied.
Fitting –

First job was to isolate the mains supply to the existing detectors which are on their own dedicated circuit, once this was done I twisted the detectors from the base to allow me to take photographs of the wiring.

The existing wiring was Black to Neutral, Brown to Live and Orange striped is the interconnect wire, 670MBX uses Blue for Neutral, Brown to Live and Grey for the interlink, the existing detector had a ferrite bobbin through which all the detector wires passed, whereas the new model doesn’t, I decided to reuse these on the replacement units.

old

Once the cable colours were recorded, the detector was unpluged and the base completely disconnected to allow the replacement of the new base, once this was screwed into place, the connections were remade.

base

The wiring in the base looks more complicated than it should due to the change of cable colours, the existing 1mm CSA 3 core and earth used the pre EU harmonisation wire colour convention of Red, Yellow and Blue,  the cable to the new additional detectors which I have installed are in the office and IT cupboard, uses harmonised colours of  Brown, Black and Grey, as the installation has mixed wire colouring, a warning notice to this effect is fixed to the consumer unit.

While the new detector was on the desk, the battery was dated and connected, without a battery installed the detector will not engage in the base, this is a safety feature.

After making the connections, the detector base was fixed to the surface fitting by two supplied screws, the cardboard sealing gasket was then pressed into place covering the detector base fixing holes, the next step was to plug the lead into the base of the detector and lastly twist the detector into the base.

new

Within the baseplate of the detector is a small plastic extrusion  which can be removed, this is used once the detector is installed as a locking clip preventing the detector being removed from the base with the clip in place.

With all detectors connected and new ones installed, mains power was turned back on, and each detector was then checked that it showed a continuous green LED for power healthy and a flashing red LED every 60 seconds to show the detector is functioning.

The center test button on each detector was pressed and held, this caused the local unit to sound, followed a moment later by all the other interconnected heads.

I had already sealed the cables passing through the ceiling, the final job was to seal the base to the ceiling and paint the exposed part of the ceiling as a result of the base being smaller than the original one.

A point to note was that I was going to use flushed in circular dry lining boxes to make the connections in and hold the base, this would have made the smoke detector sit closer to the ceiling but would of meant a large hole being made, so I decided against it.

Job was very straightforward, adding new detectors was easy as I looped off the landing detector to the other units which were only a few meters away.

ESi Electronic Hot Water Cylinder Thermostat – ESCTDE/B

In order to save energy and better regulate the temperature of my domestic hot water in my Santon Premier Plus unvented cylinder, I decided to install a ESCTDE/B Electronic Dual Cylinder Thermostat manufactured by ESI Controls, I bought online from PlumbNation.

box

The ESCTDE/B has two thermisters, one for the temperature reading and control, the other is for over-temperature trip and is set for 80℃, I must have a big problem if this operates as my boiler output temperature is set to 68℃.

thermistor

Fortunately the Santon Premier Plus has a spare thermostat pocket which the thermisters are a perfect fit.

pocket

I marked the location of the thermister pocket on the outside of the cylinder cover and offered up the ESCTDE/B back-plate and marked the center hole.  I’m not sure what the ESCTDE/B is specifically designed to fit, but the rear fixing was perplexing and I didn’t want to modify the casing of the unit in case I invalidated the warranty.

Rear fixing arrangment

I used a cut down 20mm Female Adapter as a center bush, this was cut to size and fixed to the front cylinder cover.

ESCTDE/B fixed to the bush with the three back-plate screws and as the female adapter has a serrated edge, it holds very well, the existing cylinder thermostat was turned up to position 5 which is 72℃, I have left this in circuit as another backup to over-temperature, as mentioned earlier, my boiler output temperature is set to 68℃, so only under a fault condition should this protection operate.

Cover

I used 1mm 4 core and earth from the ESCTDE/B to the heating connection box, the ESCTDE/B does not have an earth connection, so this wire was parked, the unit requires a permanent 230v feed, the temperature calling relay changeover contacts are volt free and are simply wired in series with the existing cylinder thermostat.

As the bending radius of the connecting wires within the unit is quite tight, I used ferrules on the end of the wires, this ensures that no ‘whiskers’ can cause problems later.

Finished installation all working, as my hot water system is directly fed, (no header tank), I did not need to enable the ‘disinfection mode’, this mode increases the water temperature to 61℃ to kill Legionella, however, as the feature exists, I set it to activate once per week.

finished
We had been away for a few days hence the water temperature was showing 21℃, the unit was initially set for 48℃ and the Red lED shows the cylinder is calling for heat.

Central Heating Enhancement

I was reading on the plumbing forums about the need for an Automatic Bypass Valve (ABV) on central heating systems and compliance with the HM Government  document – Domestic Building Services Compliance Guide, specifically the need for a ABV (page 15, section 2.0).

I have a System configuration using a Valliant Thermocompact 624e boiler, the purpose of the ABV is to maintain a consistent flow through the boiler and also should both the hot water and central heating zone valves close due reaching the set point temperature, the boiler will continue to run for 10 minutes to dissipate heat in the the boilers heat exchanger, without some form of bypass the pump will be pumping against closed valves, which is not good!

The ABV senses the increase in pump pressure and opens against a calibrated spring pressure to maintain water flow.

S Plan

My central heating system had a 15mm hand valve cracked open between the boilers flow and return for this purpose, the 28mm pipe with an automatic air vent is the feed from the boiler, the centre 22mm pipe is the return.

start

The advantage of this configuration is that the pump can not pump against a dead head, the disadvantage is that a portion of the heated water from the boiler is immediately returned to the boiler and not used the heat radiators or hot water, so I thought I’d install an Automatic Bypass Valve not realising that the boiler already had an inbuilt one until I had bought all the parts…oh well!!

The manual bypass valve was not the only thing I wasn’t entirely happy with, the main niggles were the motorised valve to the heating circuit was mounted very low and it would be better to move it higher for ease of replacement and the automatic air vent was not at the recommended height above the highest point in the system, both of these were going to be fixed at the same time as the installation of the ABV.

First job was to electrically isolate all power to the boiler and controller, once done it was a matter of draining the system down, I’m fortunate that my radiators have drain valves, this made the process very simple.

Once drained I could disassemble the pipework.

strip

I retained the hand valve for adding inhibitor and for use as a vacuum break should I need to drain down in the future.

Once the pipework was apart, I used a 22m straight compression coupling to extend the central heating pipe, lifting the motorised valve  to a more accessible location, the pipe to the automatic air vent was also extended to be 300mm above the height of the upstairs radiators.

The tricky job was to unsolder a 22mm stub which was cut to allow the pipework to come apart.

solder

With the heat mats in place, I was surprised how easy it was to desolder the stub from the feed pipe elbow, once the stub was out, I could start to  dry fit the pipework so that the ABV exit pipe was directly inline with the return from the hot water cylinders heating coil.

Once everything was aligned, I removed the head of the ABV so as not to melt anything inside it when I started soldering the fittings.

finished

This is the finished job, I used another compression fitting on the return pipework to make any future ABV replacement easier as the whole assembly can be broken down, something you cant do with soldered fittings.

British Gas replace one of the motorised valve heads and they don’t open the Honeywell junction box to connect the new head wiring, they add an external junction box which looked naff, so I remade the head cable off as it should be done.

The system now needed to be refilled, I coupled a length of 15mm copper pipe with a tundish to the original hand valve and added 1 litre of Fernox Protector F1, once done the pipe was removed, valve closed and a screw cap was fitted.

Mine is a closed system with no head tank, a filling loop from the cold water feed is used to add water and pressurise the system, as I knew there would be a lot of radiator venting, I installed a water pressure reducing valve inline with the double check and isolating valve already installed, this allowed me to set the filling pressure at 1.2bar and leave the valve open, rather than continually repressurising the system after venting air, this worked really well and saved loads of time.

loop

The picture was taken after all the air in the system was vented and the boiler pressure was 1.4bar and steady with no leaks, the loop was disconnected and capped off until next required.

To keep a beady eye on the the pressure over the nest few days I used a home CCTV system 🙂

pressure

The main problems I had was not having all the correct fittings to hand when you have to adapt from the original plan, I started the job on a Saturday morning just in case, and fortunately Screwfix is not too far away and they had everything in stock, including a new 22mm pipe slice as mine had packed it.

One thing which bothers me is that the builder used copper pipe where it can be seen and plastic where it can’t, this means that as your cutting pipe, it starts to turn inside the transitional coupling!!

I hate with a passion plastic fittings and have little confidence in them, fingers crossed they will last the test of time.

Sonoff POW – Power Measuring WiFi Switch

Sonoff POW is a WiFi switch with the added facility of monitoring power consumption to the load it switches also it can run trends over time and give instantaneous readings.

I currently use a Belkin power meter inline with my home network UPS so the Sonoff POW is a great addition enabling remote monitoring.

The first job was to attache the IEC plug and socket to the Sonoff POW, I had a small IEC extension cord which I simply cut in half and used that.

cord

Stripping the cable back, I used bootlace ferrules on the wires going under the spring connection terminals for a neat job.

connections

Once the connections were made, the lid was fitted which has integral cable grips to keep the cable from being pulled out.

lid

Making sure that the socket is used for the Input and the plug for the Output, I powered the unit up and paired it with my iPhone and the internet.

phone

To connect to the UPS, I simply unpluged the IEC plug suppling the UPS and placed the Sonoff POW inbetween, using the plug from the Sonoff POW output to reconnect to the UPS and thats it!

in line monitoring

The reading from the Sonoff POW and the Belkin seem to tally up, so well pleased, regarding the On/Off switching function, I will be using this test the operation of the UPS by simulating mains failure, the Sonoff App software allows for a detailed schedule to be created, so may well automate this as some point.

Sonoff Basic Voltage Free Relay Changeover Modification

What is Sonoff –

Home automation is “The Internet of Things”. It simply means the way all devices or appliances are networked together to provide customers with a seamless control over their home equipment.

Sonoff is an affordable device that provides users with smart home control. It is a WiFi based wireless switch that can connect to a wide range of appliances. Sonoff transmits data to a cloud platform through the WiFi router, which enables users to remotely control all the connected appliances, via the mobile application eWeLink. The cloud server of Sonoff is Amazon AWS global server.

Sonoff makes all home appliances smart. As long as the mobile has network, users can remotely control the appliances from anywhere at any time. Another feature available is to set timing schedules for the appliances, which can include countdown, scheduled on/off, and can thus, help users maintain an easy life.

wifi

The unit I needed to modify was the Sonoff Basic, this is a simple WiFi enabled unit which will switch 230v on or off, however, the application I needed was for it to switch a set of voltage free contacts, as these cost less that £6.00 each, its worth a go with the soldering iron.sonoff

The unit is very compact and before starting, I paired it with my mobile phone and checked that it worked correctly.

The top simply clips off the base and the PCB comes apart without any fixings after cutting the paper security seal.

The relay has the Sonoff sticker on it and the mains is switched through the relay, the board uses double sided tracks for this.

The relay was desoldered and removed from the PCB, this then allowed access to the tracks which were cut with a Dremel.

bottom cut

The picture shows the bottom of the PCB with the tracks cut from the 230v input and a shorting link to complete the relay switching circuit.

top cut

This shows the relay back in place and the top tracks cut, the modification now allows a voltage free changeover which will be used to bring on my low voltage triggered external lighting.

Sonoff Power Switching & Hive Light in Workshop

Sonoff Power Switching & Hive Light in Workshop

I’ve wanted to do a few tweaks to the home workshop for a while, and today I finally got round to it.

The easiest job was done first, this was to install an additional light fixture to house a Hive Smart Light, this has been added to the global Group ‘Lights’ in the Hive App, by the simple Alexa command ‘Lights On’ or Lights Off, all Hive lights and sockets with connected lights operate, this is really handy feature should we hear any noises in the night.

The light can also be turned on independatly via the Hive  App or via interfaces to other Apps’ or IFTTT.

hive light

I bought a cheap and cheerful circular light fitting for the Hive light as it’s very easy to wipe clean.  In the application I was using the hive light for, the lamp required an unswitched mains supply.

The besa box Tee above the Exocutor had the ‘loop in, loop out’ wiring for the suspended light, the new fixture was simply fed from permanent live from this and was up and running within 5 minutes.

The second job is something that I have wanted to for ages but the cost of the technology was prohibitive, until now!

workshop

The picture above shows my conversion of a garage into a workshop, this was done in 2007, after the walls were lined, the dado trunking and socket outlets were installed, you can make out that I have used Red and White sockets, the Red ones are not switched via a contactor, whereas the white ones are.

white red

Operating any of the three ‘Emergency Off’ latching buttons, will disconnect the sockets and non Red fused connection units.  A Red LED indicator by the bench  illuminates when the Power to the sockets is ON.

stop

The existing arrangement works fine , but I have always wanted an easy remote ‘power off’ ability, as I have had to check on countless occasions if I have left a soldering iron ON, my usual ‘gotcha’ is the compressor ‘kicking in’, in the middle of the night.

With the cost of internet enabled and Alexa compatable WiFi Smart switches coming down to a ridiculous price of £4.39, now was the time to make the addition of remote operation.

iso

To the left of the change-over switch is the consumer unit feeding the Garage sockets via a 20A MCB, a 3A MCB is for the contactors control circuit via the latching stop buttons.

The idea was to install a Sonoff Basic WiFi Smart Switch to switch the supply to the contactors control circuit.

Cables fished in, Left side is the supply to the Sonoff, the Right side is the Sonoff’s switched output.

finished

Completed job with Sonoff showing link to server established, before starting the work I configured the Sonoff in the house and enabled the power to be ON by default, once this was done I checked that it work in the Garage.

The configuration is very easy and the App is EWelink, also this is linked to Alexa, the image below is a screen shot of the EWelink App.

The blog on the Rig switching is HERE.

Update – 5 Jan 18, E-WeLink servers have failed this means that control of the Sonoff devices is not possible, no time given as to restoration of service 🙁

14 Jan 18 – Service back up and running and all Sonoff devices now working.

Sonoff 4Ch Pro WiFi/Internet Switch Linked to Alexa

Sonoff 4 Channel Pro

sonoff

I have had an Amazon Dot for a while and use the interactive plugs and lights all the time, one of the plugs is for my Ham Radio PSU, so I have been looking for a relay interface which will work with the Amazon Dot, one of the key requirements is that the relays must be able to pulse on then off.

The Sonoff 4Ch Pro costs ~£25 and has 4 programmable relays including the ability to ‘inch’ a relay (pulse on then off), the reason this is important for me,  is that it allows a momentary trigger to the PLC controlling my automated mast.

The Sonoff 4Ch Pro is well made and can be powered from either the mains or 5 – 24v DC, relays are all voltage free.

The Sonoff App is EWeLink and allows direct control of the relays from anywhere, this App is then linked to the Amazon Alex App to allow voice control of the relays,m if you want to use voice control from your smartphone, Reverb is good.

EWeLink App needs an account setting up, once this is done, follow the instructions to pair with your router.  The default pairing LED flashing sequence did not work for me, I had to keep my finger on a relay button until the blue LED rapidly flashed and then followed the instructions.

Once paired, the blue LED remains steady, after a power down, WiFi locks within 20 seconds.

Sonoff Enclosure

I decided to mount the Sonoff 4Ch Pro in a 220 x 150 x 96mm ABS enclosure (£9.70 eBay), in Visio I drew the cutting stencil and transferred this to the enclosure.

The width of the Sonoff needing trimming slightly to make a snug fit, the get the correct height I packed the unit with 25 x 25mm wood off-cut.

Using a Dremel equivalent, the lid was cut to accept the Sonoff.

The IEC plug and socket stencil was attached to the side of the enclosure, using a scalpel, the cutting pattern was transferred.

Update –

Had a huge headache trying to get this unit to re-pair once I had done some modifications to my home network and access point, looking through the help forums a large number of others are having the same problem, the solution which worked for was to put the iPhone in ‘Airplane Mode’ and follow the process to pair an Android phone (Touch) and not AP which had worked previously. What didn’t help was an unannounced outage of the European Sonoff servers!

The second issue which came to light was relay 4 would randomly operate, the fix was very simple, press and hold the internal S5 button to erase any pre-enabled RF switches.

Davis 6410 Anemometer Reed & Bearing Replacement (2000 – 2013 version)

Davis 6410 Anemometer

25 October 17 my wind speed sensor failed after 9 years service, the symptom being that the wind speed is always at zero after checking the connection to the ISS is tight and the cable to the anemometer is not damaged.

This is the blog is how to replace the reed switch and test its operation, also while it was in bits, I thought I’d take the opportunity and replace the bearings as well.

model

Information Sources

Online sources of information relating to replacing the Davies 6410 reed switch –

Parts Used

Magnetic Reed Switch 10mm MKA-10110 100v 0.5A Russia £3.50 for 10 from eBay.

Metal Sheilded Bearing 0.125 x 0.375 x 0.156 Part R2zz £0.85 each from rcbearings.co.uk

Tools Required
  • Pliers
  • Sharp knife
  • Marker pen
  • Phillips screwdriver
  • 1.25mm or 0.05″ allen key
  • Soldering Iron & Solder
  • Magnifing Glass
  • Terminal Screwdriver
  • Glue gun (or similar adhesive)
  • Multimeter or battery & lamp.
Step 1

Remove the vane and wind speed cups to avoid damage.

Undo allen screw, if tight, use penetrating oil first, the screw does not need to come out.

Once the allen screw is loose, the vane is an interference fit, and with a little gentle force, pulls up revealing the potentiometers (pot) shaft.

vane

The shaft is not ‘keyed’ but will have a mark where the allen screw tightened against, when you reassemble, use this to align the vane so the screw tightens in the same place.

direction shaft

I marked the shaft showing the allen screw mark, I also marked the body of the pot in relation to the housing so that when I reassemble everything is in the same position and the wind direction reading will not be out.

pot

Step 2

Using the same allen key, undo the securing screw on the wind cups, once loose, the assembly slides off the shaft with little force.

wind

Put the wind cups and vane in a safe place till later.

Removing the wind cups reveals the reed switch which can only be accessed by removing the pot.

reed

Step 3

Breaking down the arm and releasing the cable, this is important when we come to remove the pot.

Undo the machine screw and slide this out, once the cable has been released from the in-built grips of the mounting bracket, the tube should slide out of the housing.

arm

The cable inside the tube has a crude cable grip made from an off-cut of plastic hose, either use pliers or a wood screw in the center of the hose, and gently tease it out.

hose

The next part is to slacken the two allen screws which hold the wind and direction body to the arm, once done, slide the arm down the cable to give you working room.

arm

Step 4

Removing the pot, this is a push fit and held in place by hot melted indents, these need to be cut away with a sharp knife.

pot

cut

Once the indents have been cut away, the pot will pull out of the housing, NOTEthis is a tight fit, use pliers to hold onto the pot shaft and draw towards you, Warning – I pulled too hard and pulled wires off  the pot as their is not much slack in the wires from the reed switch, it’s not the end of the earth if you do though as I cut them off anyway!

pot
Note red wire snaped as I pulled to hard removing pot.
Step 5

Remove the gunge from the rear of the pot and note which colour wires go where, the red and black fly lead go to the reed switch and these I cut, I also cut all wires to the pot and removed this so I could easily work on the reed switch and bearings.

pot

pot

Step 6

The reed switch is held in place with the same gunge (hot glue?) as is on the rear of the pot, due to aging it had gone brittle, using a terminal screwdriver it was possible to break this up from inside the housing body.

reed

Once glue is removed, the reed switch assemble will slide out.

pot

Step 7

Reed switch replacement, the reed didn’t appear to be visually damaged, only slight rusting. Testing with a meter and magnet, the reed flexed but no electrical contact was made, checks on the circuit board tracks and resistors were OK.

reed

The zoomed pictures make things look easier to handle than they are, the picture below offers some scale.

reed

New reed soldered into position with the contact leafs horizontal to the orientation of the PCB, I also replaced the Red and Black wires from the PCB with more flexible ones.

reed

Once the reed switch excess wire was trimmed, sliding the PCB into the housing body and getting it flush broke the reed.

broke

The cause was the reed needs sit,as flat as possible,inline with the PCB, I had used too much solder and this lifted the reed wires slightly off the PCB.

The picture below is the second attempt where I used minimal solder on the PCB pads and pressed the reed wires onto the pad before using a small amount of solder to connect to the pad. This seems to have worked and allows the PCB to slide into the housing and sit flush once the wires were trimmed.

rred

reed

After sliding  the reed switch in the body, I connected a multi-meter on continuity buzzer setting, sliding on the wind cups and spinning them, this should cause the buzzer to sound once on each revolution.

Once correct operation is proved, remove the wind cups and reed switch assembly, I sprayed the reed switch with a protective coating and put them in a safe place until later.

spray

Step 7

Replace the wind shaft bearing, first the circlip needs removing and retaining for later use, once the clip is off, the shaft can be pushed into the housing.

shaft

The shaft and black cap can now be removed.

top

My model has the brass follower looking from the cup side, other pictures I’ve seen show this to be the bearing with the brass follower inside the body, I reassembled in the same order as I took apart.

follower

To remove the bearing, I left the brass follower in  and used a terminal driver to go through the hole and using it at a slight angle, gently tap against the underside of the bearing, moving around the inside of the bearing and tapping to tease the bearing out of the housing.

The old bearing is in the bag and it is in good condition with only slight signs of rusting.

bearing

The new bearing simple pushed into the housing.

Step 8

Reassembly:

  • Slide shaft into place and fit circlip, make sure the shaft spins freely, I applied a light oil to the brass follower only.
  • Slide the reed switch into place and making sure that it sits flush, after putting the bearing protective cap on and I then used hot melt glue from inside the housing to secure everything in place.
  • Checking that the cable is still threaded through the arm, pass the cable into the housing ready for soldering onto the back of the pot.
  • Once with wires are back in place, I sprayed a protective coating on the pot and pushed it back into the housing checking that the marks I made at the start are aligned.
  • I didn’t melt fix the pot, the protective costing will act as an adhesive.
  • The arm was then re-affixed and secured.
  • The arm cable grip was pushed back in, check that the fixing hole is clear for the machine screw when pushing the grip back in.
  • Fix vane back on to pot, aligning grub screw with marking on shaft.
  • Fix wind cups onto shaft.
Testing

I used a Glaxio Telecom Wall Box RJ11 which cost £2.69 from eBay as a breakout box for testing that the reed and directing pot are working:

My old 6410 is now refurbished and will be stored in the loft until the one in use packs up.

This is the original blog  on my weather station, the latest information is containained within the pages of this site via the WEATHER tab at the top of the page:

18 May 14 Really warm weather currently which is great timing for the PC to stop sending data! not sure what the problem is as it’s been running great for weeks. It looks like its a usb data related problem because if I disconnect the Davis Console mini usb and then plug it back in, data logging on the Weather Display software kicks in and all is well for about 4 hours, then it stops again, in case its something to do with the usb logging driver, I checked my version in device manager against the latest on the Silicon Labs web site, the web had a 2013 version which I have downloded and installed, everything looks good at the moment, so fingers crossed this has sorted it.

I have downloaded WordPress and use this for my blog, this can be accessed from here www.chatteris.biz/blog, their is a direct link in the menubar, this blog is a lot easier to update so this one will eventually stop being the latest blog news.

18 April 14 The main hiccup over the last few days has been due to Weather Underground making website changes, these changes have had an effect on the Saratoga Template that is widely used, fortunately Ken True is an accomplished expert in code and had made the required modifications to get the template back on track, the main issue was to do with forecasting, luckily Chatteris Weather has it’s own weather modeling software so the impact wasn’t as great for me as it was for others, the main thing is that the status quo has been returned.

Few changes this week, I’ve added a weather calculator and conversion script, this accessed from the ‘Useful Links’ page, from the menu bar I’ve added a Radio Player and an enhanced pollen chart, the original links for pollen maps within ‘Community Interest’ have been removed, another change has been the addition of an ‘On This Day’ page and the inclusion of a couple of widgets in the ‘Advisory & Alerts’ > ‘Weather Advisories’ for the Met Office and Flood Warnings.

10 April 14 Busy playing adding new scripts and moving items around on the menu bar, new additions have been the WeerstationLeuven template for displaying the output from the WXSIM weather modeling simulator program, also I have incorporated a Saratoga template which displays affiliated weather stations who freely broadcast their raw data for use by other programs.

I have also added a ‘goto’ button for long pages, clicking this takes you directly to the top of the page, saving constantly scrolling, I’m experimenting with scroll buttons from Dynamic Drive, and these can be seen on the Forecast & Advisories > Chatteris (Long) page.

Had my first spam using Capcha enabled contact form, the script from Mike Challis fortunatly has ip blocking, so this spam has been added, hopefully it will work!

4 April 14 WXSIM now reports wind speed in mph and their is an RSS icon on the home page to make subscription to the forecasts which are updated every 6 hours only a click away. The ‘Who’s-Online’ page now shows a mapped location of visitors and a 30 day history feature, as this script only became effective today, history is being built up from now. Changed my e-rice hosing package to Standard 3, this means an increase of connections from 3 to 5, the effect is that I will no longer have to turn off Nexstorm lightning reporting whilst I’m uploading which is good news.

Installed a second hard drive into the weather pc, using Acronis software I’m able to ‘mirror’ the ‘C’ drive and keep on top of backups, fingers crossed I’ll never have to need it!

31 March 14 Yet more tweaking of the site, added WXSIM weather forecasting programme and a ‘Who’s Online’ page, I’m in the process of using yet another brilliant Saratoga script to rss the weather forecast.

23 March 14 Been an eventful few days, the town has suffered power outages not only did this stop us going to the pub, but it also interrupted weather data from the station to the internet, all back on now though with no real glitches, the main additions to the site are:.

  • Newly registered www.chatterisweather.co.uk and www.chatterisweather.info, these forward to chatteris.biz, hopefully it will make remembering the stations name for access easier.
  • Added Twitter feed to the Weather Cam > Current View cam page, this will help me test that the feed is working and also help visitors to decide if it is something they would be interested in following.
  • Added radio propagation information and satellite tracking maps on the Space Weather page.
  • Sun and Moon – Sunlight Graph has been playing up, sometimes it works, other times it shows the dreaded red cross in the corner, currently its working as each time it stops I have to upload Sun48.png and jpmoon.png files again to the sites root directory, hopefully one of the experts on the weather forums can help me to fix it once and or all.
  • In Community Interest pages changed a few of the links, especially the one to UK Power after our power cuts!
  • In Useful Links I have added a number of links to scripts, without the time and effort of these gifted scripters, chatteris weather would not have got off the ground.
  • I have introduced a Warning Service, this will send an automated email to those who use the contact form and request it, the warning service page lists all the thresholds, this service also extends to thunderstorm notifications.
  • Stumbled across a download from Astrogenic Systems called SPARK.CLX, this allows legacy cell phones to view NexStorm lightning detection output, a link is on the Warning Service page, can’t see that many people using it as most mobiles can simply view the whole website which includes the sites lightning pages.
  • A Photograph gallery has been incorporated, this will be continue to be added to.
  • Contact Us form has been amended to included a drop-down selection menu box to help administer alert subscriptions.
  • Changed a tab to ‘Take a break’ from ‘Lottery’ as I’ve added a number of games.

2 March 14 Relocated solar sensor is performing well, one anomaly noted was that the Weather Display software predicts a solar curve based on the longitude and latitude of the weather station, and yet the solar sensors peak greater than this making me question the accuracy of either the prediction curve or sensor, it appears that the solar curve is derived from a cloud free day, what is happening to make the readings to peak past the predicted maximum in my case is solar reflections from broken clouds, this explanation may be of use if you are looking at the graph containing solar information and wonder why the discrepancy. Graphs can be found here, of accessed from the main home page of Chatteris.biz.

Road Traffic pages have been added to, links to the Highways Agency and to Frixo for an alternative live traffic information pages.

Marine Traffic had an outage, this is now back online.

Status of lightning detection is now displayed on the header of all pages, this is a dynamic indicator, so I’ll have to see what effect it has on the page formatting when it picks up strikes within 50 miles which is the trigger for the script.

16 February 14 Camera relocated to the West side of the house, also the UV and Solar sensors have been mounted above the ridge line to give an uninterrupted view of the sky, certainly a huge improvement over where it was originally.

15 February 14 Chatteris station record winds of 50.1mph have been recorded today, this caused ‘The Lucky Parrot’ building in East Street to collapse and intermittent power outages.  Added a Marine Traffic tab to the site showing shipping zoomed to the Wash area, the map allows you to zoom out world wide, this page also gives the details of each of the icons when clicked on.

9 February 14 Made some minor additions and tweaks to the web site:

  • Added postscript after the countdown clock indicating the season leaving.
  • Added wxalltimehigh script this has been included in the ‘Almanac’ fly-out menu and list station records.
  • Included a script which will bring up an alert box on the home page of the site when any station record has been broken, I chose for the alert box not too be visible when no record has broken.
  • Menu bar items moved about to make it a bit more logical.

Glued the external sensor assembly together and the new pipework parts arrived from Harrison Plastics, everything is ready for installation once the winds abate.

7 February 14 Added a season countdown clock to the main home page, in the ‘Links’ section is a shortcut to the scripts author.

6 February 14 Added a RSS feed button to the home page, this feed will be updated when I add pages or make changes to any aspect of Chatteris Weather.

5 February 14 Weather Buoys page added and some minor tweaks done. UV and Solar sensors have been mounted in a new housing ready for mounting on the same tube that supports the Boltek lightning sensor.

2 February 14 Disconnected the weather station to allow me to run and connect cables ready to move the UV and Solar sensors, these have been removed from the system and will remain so for the next couple of weeks until I can get the ladder out and mount them higher, no real point leaving them connected as the readings are quite inaccurate, during the connection process I knocked the rain gauge, so for today it indicated 0.2mm of rain which is not the case, I will try and get this removed from my stations stats, so please note that it didn’t rain on the 2nd!

1 February 14 Added a few things today, to highlight what has been done since peoples last visit, you may see a flashing ‘New’ icon, these will stay next to the relevant tab for 5 days before being removed, new items are the CWOP quality status page, I have been exporting data for quite a while and I’ve mailed them about getting registered so that my data can be quality checked if it’s possible. Raw data is a new fly out tab, this tabulates everything the weather station sends out and will allow me and others to check if the information leaving the weather computer is current.

Weather Map Live went on line yesterday, I’m still playing with this, so be patient with me if at times it seems all over the place, I will remove the message under the map when I’m happy :-).

31 January 14 Installed Weather Extremes tab, this is a great script from Relay Weather which shows maximum and minimum temperature and rainfall, I have down loaded a few scripts from his site and aim to get these working over the next few days.

29 January 14 Lots added to the site in last few weeks, some of them are quite subtle such as the animated forecast icons and the wind rose changing colour making it easier to read, also a few pages now automatically go full screen to match the page they display.

Recent pages added to the site have been the flight radar showing the aircraft overhead, where they are going, where they have come from, clicking on the airport icons displays arrival times. The tide page has been improved to show a tide clock for Hunstanton (we love taking the kids there, especially when the tides out so the dog can have a run), other improvements have been a new lightning page and rehashed VP2 console which mimics the display of the main controller.

One other thing I have done since the last post was to advertise that Chatteris weather exists in ‘Shape your place’, so pass the word! Till next time.

11 January 14 Added lots of functions to the site, these include RRS display box which automatically displays weather warnings issued by UK Met Office, a facility for mobile users to view the weather data in format suitable for their device (www.chatteris.biz/iwdl) and finally webcam time lapse options.

I have also linked Twitter outputs from the station to Facebook.

5 January 14 Work is progressing well using the Saratoga template, the advice from WXForum has been indispensable, as a novice with regard to web code, I would have been lost without the help of the experts on the forum, the other place I lurk is the Weather Display Forum, again, an invaluable source of information.

I have changed the logo from a fat man as I need to lose some weight this year, so it got changed to a picture of the wind turbine farm, just off High Fen Straight Drove (A141), the picture was taken on the 3 January 14.

28 December 13 Well finally took the plunge and decided to download a website template from Saratoga (Saratoga-Weather.org), the new site is accessed via the normal address of www.chatteris.biz, this site is linked back from the home page of the Saratoga template, this site can be accessed directly by entering www.chatteris.biz/oldindex.html.

I will keep this site updated as things develop, so I have not abandoned here that’s for sure.

Hope you have a great 2014, all the best, Ian.

7 December 13 High winds and tides on the 5th December caused localised flooding on the Norfolk coast, worst combination of events in 60 years, winds recorded in Chatteris measured gusts of 46 mph.

21 November 13 Added pictures of my power transfer switch and intake in case of utility power failure, over the last few days I have been setting up another PC after a hard drive failure, everything is going ok apart from the Comms port on the Virtual Serial programm doesn’t work and also WeatherLink keeps dropping out, hopefully this will be easy to sort out with the help of the forums.

20 October 13 Well it’s been a while, so I’ll start with the Blitzortung problem display, this needed a new one, I found another company which was cheaper than Mouser, so it cost £26 to replace and it was now all back to normal, the Boltek lightning detector had a damaged RS232 circuit, the unit was returned to the manufacture via Skyview and they repaired it free of charge which was superb customer service, I use a laptop at the moment which hasn’t a serial port and I can’t seen to get a USB to Serial converter working, so I’ll be transferring everything back to a PC soon so I can get the lightning map on Weather Display working again.

1 September 13 Well lots has happened since my last update, the main one being that the Blitzortung lightning detector, boltek lightning detector and external camera all stopped working, the only thing they all had in common was a earth I fitted a week or two before, problem started when a circuit breaker operated in the night, the UPS kicked in but the batteries exhausted and power was lost to the system, on power up next to nothing worked, to compound this my weather PC hard drive did indeed pack up.

I replaced the STDiscovery board on the Blitzortung and it came back, although the display is damaged and only shows half the information, the other thing is that the signal has gone really noisy on the red channel, not sure why but at least it’s working.

I have got the weather programs on a laptop, so that’s what I’m using at the moment, the loss of camera feed was the external balun stopping working, so we are nearly there.

Transferred programs before the hard drive failure so I’m in the process of getting everything back together, it’s been an arse of a last few weeks to be honest 🙁

24 August 13 Did a few jobs on the Blitzortung system today, first job was to flash a new version of firmware into the controller, the system is pretty cool in that it tells you on the LCD display that a newer version is available, you also get a message when you login to the controller, I was a bit nervous at first about doing this, but I’ve done it 3 times now and it’s really straight forward and as long as it keeps working afterwards, I’m happy.

I was in the loft, yet again, installing a longer shielded cable for the lightning amplifier so I can move it away from where my computers are, I could only move it 5 meters, but I can now ramp the gain up slightly higher than before without going into the dreaded interference mode.

My eBay 10 meter USB extension lead came today, this is used to connect my UPS monitoring software to the PC running the Weather Station stuff, the cable was a bit of a bitch to get in but I got their in the end with a bit of help from the wife, just got to figure out how I can get it to automatically shut the PC off before the UPS batteries fail.

20 August 13 Adding more information and updating the site, installed an energy monitor from Amazon, at £8.00 is great value, my total configuration measures 315 watts, when the monitors are off it drops to a normal running value of 280 watts, could do with getting it lower but that will involve getting a different PC, so it will stay as it is for now.

18 August 13 Busy few days, the main job was to try and get the weather station PC back up and running fully, I had not been able to update the webcam since the lightning strike damaged the mother boards USB ports, the Video card arrived (Hauppauge PCI) and was fitted OK, bit of hassle getting the drivers, but’s it’s ok now, a major bonus was the PCI mounted USB card, this worked straight away and so I could simple plug the Davis USP lead in, and I was back in business.

While I was waiting for the bits I have mounted the Blitzortung antenna and GPS in the loft and rewired things so that everything related to my weather station is via a UPS complete with new batteries, updating all the web pages now to reflect the changes and add so pictures, I just love this hobby, but boy it can be frustrating!.

12 August 13 Well what a nightmare! Decided to move the Davis console from free standing on my desk, to mounting on the wall, all went well apart from I couldn’t get it working again, checked and double checked everything (I even learnt their was an LED on the ISS which I have never noticed before), anyway thanks to all the guys on WXForum who helped, it turned out to be a dodgy connection on my patch panel, and to further confuse me, as I was fault finding, the lid of the ISS caused the plug to the console to not make a really good connection when the lid was slid down, I had to make sure the wire was in the groove to the side of the board.  Luckily I’m back on air so to speak, pheww never again.

6 August 13  Done a few things this week, I’ve put an earth rod next to the weather station and earthed the cable containment and camera, pictures to follow, the other main things is to start construction of the lightning detector, I posted for the first time ever a couple of videos on YouTube, let me know if you like them or not!

My other new adventure was that of Twitter, the link is at the bottom of the main page and Weather Display will send from 07:00 to 19:00 at 2 hour intervals current weather conditions in Chatteris, again let me know what you think.

August 13 Turns out it was the KWorld weather cam video capture USB device that damaged the mother boards USB ports as it also has given up the ghost, looking at the last image transmitted to Weather Display Live it was damaged at around 03.40 on the 23 July 13, must admit to not hearing a thing as we were in Gran Camera 🙂

Ordered from eBay a PCI video card for £2.99, so I’ll have to see how that performs, (if I had the money I’d use media converted to fiber and separate the PC from any external influence, well apart from power of course)

30 July 13    Just got back from holiday to find we had missed huge lightning storms and a couple of power outages, not sure which to blame but the weather station PC USB ports no longer work and hence the web site was not being updated, I’m up and running using my office pc to ‘back feed’ the weather PC using VP Virtual and running weather display in IP mode.

Ordered another HP second hand pc with a lower spec, and I’ll butcher the hard drive and RAM out of my original station to get back up and running fully, one good thing is that the Blitzortung kit has arrived as have the parts to put the weather PC on the main UPS (bit late now grrrrr).

21 July 13    Added a site map as I’m new to this and the pages are growing all over the place and if I don’t know where stuff is, other won’t have much of a chance either.

20 July 13    Finally sorted the problem of my host server filling up with time stamped images doing the following:

  • Weather Display – Control Panel – Web Files/Web Page Real Time FTP/WDL – Time Stamped File Setup – untick ‘Upload the latest time stamped jpeg web cam file every minute’.
  • Weather Display – Control Panel – Web Files/Web Page Real Time FTP/WDL – Animated Web Cam Images Setup – untick ‘Still upload the normal web cam image (at the web cam upload times)’.

Revolver Map detected my first visitor apart from me!

19 July 13        Fighting to get the webcam to update without filling the host server with time stamped images, working on it but Weather Display has so many settings it can be a bit confusing.

  • Ordered my Blitzortung lightning detector kit today, so that should be a nice project to construct and get working.
  • Installed Revolver Map, it’s out of interest, I won’t get hung up if it’s only ever me who checks it out 🙂

14 July 13       I’m using Expression 4 which is free download from the internet, and it’s getting easier the more I do. I have added quite a lot of pictures and links today as I move down the Configuration schematic filling in the detail as I go.

11 July 13    Managed to work out using iFrames how to embed Weather Display Live into the main page, had an issue where Weather Display wasn’t updating the web cam images which was really frustrating, this was resolved by re-entering the settings, not sure why it stopped working, but it’s back now, this means that the webcam image is uploaded every 5 minutes with the display auto-refreshing every 2 minutes, I will be posting up screen grabs of my setup as it may be of use.

General information and status updates.
