    Component Identification

    It’s probably a semiconductor.

    110 220V detection

    Wouldn’t a SMPS suitable for 110V to 240V suffice?. Some voltage input range from 80V upto 240V.

    Home Based Income as an Electronics Hobbyist

    Absolutely. As Hop says “your mileage may vary “. I honestly cannot remember many things about my electronics night school (city and guilds). Apart from wasting 6 months on how to wire a plug properly!. The ‘professor’ shouldn’t have been teaching night school, he should have stayed in the...

    Protocols and Systems

    Are you connecting it to an output? Rather than input?. You say “input” then “output “.

    Old Car computer (ECM) may be faulty

    The 4 diodes definitely could have problems or even a short. Plus a short to the capacitor to the left of the 4 diodes. Absolutely clean it first with IPA (isopropyl alcohol) and the fibre glass pens are great for tracks and connections as suggested above. Martin

    SONY WF-1000XM3 loud screeching when charging case opens

    Apart from this being an old thread, it appears to have been solved. Did you read it?

    Protocols and Systems

    Perhaps i misunderstand. I thought DB-9 was RS323 protocol. I could be very wrong here, but I don’t think it’s anything to do with universal serial port (usb). RS232 ;)

    Whirlpool oven timer problem

    The grey device has refdes of a capacitor or a small bank of capacitors. The white device is clearly marked as a relay. As already stated above, should read open circuit when no power to the element/s. That relay is a typical failure point as a large current arcs across the contacts, eventually...

    Using a PIR to both turn on and turn off LEDs

    You might be better off with a simple ‘clap’ switch. Clap and it turns on, clap again and it turns off. A PIR will only turn on and time out. It’s just a switch with a timer. You can of course have it switch off when activated too. But not both. The poor PIR won’t know whether it’s coming or...

    Boardgame wiring question......

    Well, plastic is an insulator. And the heater was disconnected. Unless there is something seriously wrong with the house wiring and the water is at mains potential?. But then washing the dishes would kill you!. Martin

    Boardgame wiring question......

    Sounds more like static electricity as the heater was disconnected.

    Boardgame wiring question......

    That would depend on the zapper. Show us what you have. Series connections double the voltage and parallel double the current. (Assuming same batteries are used). Martin

    Yep, £1000 per metre. Cheap at half the price for having (well, half a brain).

    LED power on

    I agree. These must be ECU controlled and therefore constant current controlled also. Nothing to say that you can’t control the current if using in a different environment. A resistor would then be the appropriate component. Martin

    LED power on

    That LED might have built in resistors. But not knowing the voltage of the KTM, I would start at 6V. Some motorbikes are 6V, then try 12V if it’s not very bright.

    Appears to be discontinued. Why not try fixing yours?. Post some clear photos and a description of the fault. Martin
