    Malibu Landscape Lighting Parasitic Draw

    Seems to be a lot of complaints about LEDs staying on dimly when switched off. On both AC and DC, there is stray current or capacitance which seem to be the culprits. On DC a load resistor helps. On AC, the definitive solution is to switch both phases. A DPDT relay for example for these garden...

    How to keep a pc monitor on with out any connection

    There are ways to do this but can be different for many monitors. I don’t know whether your suggestions would work as there still wouldn’t be any signal. The easiest way I think would be to find the power supply for the inverter board. Then power the inverter board directly from the monitors...

    Identify part please

    Looks like a fuse or fusible resistor. Can you see any reference printed near it? Example: F1 or FR1 or R1. Martin

    Motor and battery for hobby project?

    Yes, it’s very easy. Have a look on YouTube. Here is one ( I haven’t watched) but there are hundreds. You probably have most things somewhere around the house. Broken toy?. Martin

    Motor and battery for hobby project?

    I agree with a geared motor. Example: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F264223490883 This is a small motor that should run from a phone charger or C, D size batteries. Try and imagine the speed you require for the elevator and source a geared...

    analogue pong circuit I found on the internet

    Very impressive YouTube channel. But c’mon dude, we know how you did the video feedback trick. It’s so simple. You used an oscillator and capacitors in series with the video signal. You can’t fool us. Martin

    Lg BH7440P s protection

    You will need to read the part number on each transistor. Look carefully and you’ll see it. You can’t always measure components in circuit as others around it can influence the measurement. Also whether it’s NPN or PNP, so you really need to find that out. There are plenty of online videos...

    Memory chip- reset pin

    The flash memory chips get erased by software. Normally found in USB drives and other digital storage. Using software to program and erase data. https://en.m.wikipedia.org/wiki/Flash_memory Martin

    Video or VR glasses to use with an external camera

    Yes, I see your concern. The headset has HDMI and the features say AV. You should contact them to clarify. Like most ads, they probably used a better headset for the photo. Martin

    LED lit cabinets

    This is why you need to be able to isolate the cabinet lights. A fixed (hard wired) circuit needs its own isolation switch and fuse (UK). I would be tempted to put the switch at the entrance to the room next to the room light switch. Then switch the low voltage side at the cabinets as Bertus and...

    Sorry @ratstar I am completely lost. I am sober, so that doesn’t help. Martin

    Honda MICU Breakdown

    You should take the board off and clean underneath as well. Let it dry properly. Use IPA or similar with a soft brush all over. Getting into the pins might be an issue if they are corroded. I would spray a contact cleaner in there and plug and unplug the connector several times to try and clean...

    LED lit cabinets

    Not sure what you are asking here. A lighting circuit is radial (6A) and each room individually switched. Adding to a circuit requires further switching unless it’s simply adding or changing the light fittings. Adding lighting to a main circuit (30A) will require a fused spur (socket...

    LED lit cabinets

    UK regs require or at least DID require an isolating fused point with switch or separate switch. Either a standard wall switch or under cupboard switch. This is for the lighting circuit. For the 30A ring main, a fused spur is required with a switch and a separate switch for convenience. So the...

    LED lit cabinets

    I suppose it would. If one or both switches are high (on) then the output is high (lights on). Martin

    LED lit cabinets

    You only need the drivers switched. But connecting directly to the lighting circuit will still require a fused spur (country regs dependent). You would be better off getting smaller drivers for each cabinet and one switch on each door. You want 6 non latching push to break switches. Each...

    Honda MICU Breakdown

    If it’s only water Ingres, let it dry out. Once dry, you can concentrate on cleaning the corrosion. Do you mean the PCB layers are separating? Martin
