    Repairing broken cable pls help - pc xbox 360 controller

    cut the lead completely off maybe 25mm behind where the (cat then) chewed it and redo termination. If you can get access to the other end you can test each conductor for continuity with a multimeter.

    Repairing broken cable pls help - pc xbox 360 controller

    In #3 above you said you had soldered the wires back into the board but it did not work.....??????????? Anyhow, one thing further you can do is cut back the lead further back than where the dog has chewed it, as it is likely the wires inside are broken.

    Reducing Voltage Drop over distance

    Possibly but that is entirely dependant on cable size and loading as Whones says and what we have been saying all along.

    Magnifying light voltages

    If all else fails, there are LED fluro type tubes out there which connect directly to the mains. Just need to install a supplied fuse in the form of a fluro starter between both ends of the tube and you're done.

    Reducing Voltage Drop over distance

    Usual is 5%.....

    Reducing Voltage Drop over distance

    The correct place to start is how much maximum current will be drawn and go from there.

    Magnifying light voltages

    Not the wires, the pins on the tube.

    Magnifying light voltages

    Fluorescents take a couple of thousand volts to "strike" and you won't be able to measure it anyhow. Best just to check the pins on the lamp itself. If they are intact(circuit on each pair) then the driver is kaput.

    Question about SMPS repair

    You cannot test the caps in place on the board. Can you show the other side of the board..? Preferably the top 1/3 section....

    Handholding request

    You could select either depending on the run length or the loudness of the chime. 12v should be ok. Solenoid pulses one way when the button is pressed for the "ding" and springs back under no power for the "dong". So in most instances, power is only applied for perhaps less than a second. Note...

    Handholding request

    More likely poweted via a 12v transformer. Any brand name...? Freidland for example.... post a photo and it may be recognisable...

    Question about SMPS repair

    SMPS units are anything but straightforward when you know next to nothing about them. Power resistor looks like 5w to me. Difficult to say whether it should be fusible or not given the photo is taken a long way out to be able to make out anything. Also a shot of the other side of the board would...

    SPST Non illumination of LED - Driving me mad

    Call me crazy but why would one need an LED illuminated switch when the switch turns on a light, a strobe light at that.

    Looking for a suitable universal charger for a variety of electronics

    One checks the internals. Look for an electrolytic cap close by the input.

    Pedestal fan stopped working - capacitor issue ?

    Anywhere on the stator should be ok. Word of warning, crimp the connections , do not try to solder otherwise you will have an open circuit thermal fuse once again..
