The batteries in interruptible power supplies are normally stuck side by side by using just a foam pad. These things are often rated to discharge the batteries in 5-10 minutes at full rated load

Have you taken a look while it is filling to see what is happening? Limescale on one of the other outputs causing spray to go across into softener compartment. Damage inside the water guide from the valve to the output nozzle allowing water to leak from one section to the other. Faulty water...

You don't say what size your existing pipe is. The following information is from discussions with a couple of fitters and is what they said so don't rely on it being totally accurate. In my house the distances were about the same but the pipe from the meter was 22mm and then it split under the...

www.ebay.co.uk/itm/20-50-100-LED-String-Battery-Operated-Copper-Silver-Wire-Fairy-Lights-Xmas-Party-/322489742957 These are very small. You could get one of these kits including a battery box and run the cable in the roof area of the model and have the light coming down into the room area...

Maybe this type would be a good style to use. The shape would make it esy to mount and at 100 lumens it would be capable of producing much more light than you need. http://www.ebay.co.uk/itm/10-50PCS-3V-Brand-New-1W-White-Warm-White-High-Power-Led-Lamp-Beads-DIY-Bulbs-/172017766483 They need...

In that case I would get a splitter like https://www.amazon.co.uk/BT-Socket-way-Adaptor-Splitter/dp/B009PJJ59O and then chop the end of the existing extension and crimp on a new bt plug.

Looks like a BT to RJ11 adapter like https://www.amazon.co.uk/DealMux-Telephone-Converter-Adapter-Landline/dp/B072SK9XYQ

Fitting looks quite long for a simple tap connector. Does it have an isolator built in? I would cut the pipe a bit lower and fit an isolation value and then a short bit of new pipe in the other end to a new tap connector. I am not a plumber but for me not being very experienced that seems the...

Yes certainly worth a go. That arrangement of LEDs is probably going to be more reliable anyway and they are probably 1W units so going to be run a little under rated. It would not be too difficult to replace a LED if one does fail. If one fails I would expect it to only take out one of the...

You always have the option of modifying a mains LED floodlight. The 10W variety can have two different types of LED inside. One runs at about 12V and the other at about 33V. The 33V type would actually be the easiest as you can pick up a DC-DC Boost power supply off ebay cheaply (e.g...

Would the switch be rated to work on the higher UK supply voltage? Alexa works with the Samsung Smartthings hub so looking for a light switch which works with that might be the better option. One example would be https://www.amazon.co.uk/dp/B00JGSDL1C which you could install in the ceiling...

1) Yes it will use a standard ES bulb holder. 2) Yes it will connect directly and work fine although the beam angle might be too much of a spot light. 3) I doubt they have a transformer. If you are talking about a LED type then the power supply will be a constant current switch mode type if it...

I would follow the standard electronics fault finding procedure. Step 1 is checking all the voltage supplies are present. So find the power supply and check that it is working. You might not have power on all its outputs as the main board may tell it to power on (like a pc computer does to its...

What are you planning to fit?

6*1W would just mean there are 6 1W leds which may be in parallel or series or a combination of both. A lot of the power supplies on ebay are pretty bad. They may be reliable but they often don't have the required mains separation to comply with UK safety regulations. LED drivers are constant...

If you put your ear to the sensor with the car in reverse you can often hear them clicking. Your daughter might hear it easier than you can. That is only a very basic test though. The repairer would link it up to a diagnostic system which would check and see if it was getting a response from...

The free mobile phone sat-nav app 'Waze' has had every one that I have come across in it. There is an app by pocketgpsworld I believe which also contains a database of popular speed trap sites.

It looks like a Flomasta valve. I am not familiar with that model but if you isolate it you should be able to unclip the top and inside there will be one or more rubber washers. Sometimes you can get grit or limescale stuck on them which stops it shutting off the water properly. Give them a...

https://www.youtube.com/user/jjward is quite good for general electrical stuff. It might be worth contacting Kenwood anyway. Under consumer rights the product has to be free from defects and this isn't a normal failure mode. It is probably a manufacturing defect or a foreign substance has got...

Ah so those reading are just in plain ohms. It does certainly seem like start is shorted to earth
