    PC Mainboard - CMOS Bios Battery Circuit

    Higher probability that the new battery is at fault, voltage measurements as said are very deceptive on that type of battery, buy a good one and do a very quick short circuit dab current test on a suitable current range (100mA or 200mA) (- an analogue meter is better for this), then do the same...

    Wiring PIRs

    If the PIRs are powered up but not triggered and the lights are off the PIRs will consume some power whether or not it's dark so if your mother (or you) are worried about the 24/365 overhead of powering the PIRs (which actually isn't quite as trivial as you might assume), feed them from a smart...

    Recall: Proteus Switchgear - 100 Amp Double Pole Isolator - which might not isolate.

    Yes I wondered why only e.on were mentioned. Unless it was a faulty batch that only e.on had or maybe it was that e.on had instigated the recall.

    Recall: Proteus Switchgear - 100 Amp Double Pole Isolator - which might not isolate.

    Disconnect once check twice..(or more) Found HERE at Trading Standards Risk level Serious Risk type Electric shock Risk description The fault was identified during routine installation process which includes a test. It was found that the switch did not isolate the circuit. The product does...

    Dimmer switch ring removal tool

    I meant spindle not toggle (sorry about that, you did say dimmer) and I can't tell from the photo whether the inner ring overlaps the outer or sits inside it. If it sits inside it then you should be able to remove the outer ring only and leave the potentiometer attached to the plate. You MUST...

    Dimmer switch ring removal tool

    You might try carefully placed normally closed small circlip pliers, with the pins in the slots as long as you can apply even pressure as you twist them, angled ones even better, or failing that you could always make a key by cutting a slot of sufficient depth to clear the toggle in a suitably...

    How to reduce power to a heating device.

    The device you need is another 3kW element connected in series with the first. No tangents to go off on (or sines or cosines) for this method as there is no reactance. Efficiency of energy conversion will be close to 100%, and why not arrange a suitably rated switch to short out the second...

    EMF dangers - advice needed

    I can't and won't comment on the sensitivity to em fields other than to say that there could be alternative (cheaper) ways of shielding using foil panels to create a faraday cage, which could be an easier remedy depending on construction. The OP could consider that. Do any supermarkets connect...

    Mechanical timer

    Permanent live to rhs clock permanent neutral to other clock terminal, this will keep clock going. And guessing.. Live to C and either A or B will become switched live when on or off (when A is on B will be off and vice versa) Choose whichever suits what you're doing - if it's on when it should...

    Resistance in a Volt meter

    The current doesn't "bypass" the voltmeter although I know what you are trying to say, it just may be too small to measure. Current will always favour the path of least resistance, but that doesn't mean none will flow where the resistance is higher. Typically a decent analogue meter moving coil...

    Anyone any good with a camera?

    1.How important is the size of the camera to you? 2. How much do you want to spend (roughly)? 3. Do you want to be able to change lenses or is a fixed zoom lens Ok with you Once you've answered those it will make your choice a lot easier

    Left handed people, what finger do you use?

    Windows 10 (if you're unlucky enough to have it) Open the Start Menu. Settings. Devices. Touchpad. There is a toggle on right under Touchpad. Toggle to off. Mac OS System Preferences, Accessibility Select Mouse & Trackpad Tick the box next to “Ignore built-in trackpad when mouse or wireless...

    Left handed people, what finger do you use?

    As the buttons can be configured to be either way around with os settings, what difference does it make? However, if signalling I recommend holding up a big note saying “This is really my index finger, it is not my intention to insult” Probably better on stiff card, it won’t flap about so much...

    T.V aerial installation

    I agree, you certainly need at least 2 uhf aerial connections/cables from each point where there is a receiver, to a central point (loft?) -one in, one out, (if lucky enough to have a uhf output or with your technomate), but I'd add that to future-proof further, cat6 between receiver and other...

    Gluing alarm cables to UPVC Window frames & Door architraves

    Superglue might not melt the cable, but it might melt the upvc frame and it's quite hard to contain, you risk marking the frames. Beside which you'll never be able to hold the cable in place satisfactorily while it sets/dries. I wouldn't use it, but then even though I'm mean, I wouldn't worry...

    Ethernet point no internet

    That is not true, however you can make a crossover by wiring to "A" at one end and "B" at the other. If you wired the sockets A to A or B to B either would work.
