    Hoping to ID this connector for LED array power supply

    My old laptop with windows ME had a S-video out on it. I used to connect it to my large CRT TV and watch DVDs on the bigger screen. Martin

    pioneer vsx-d307-ht

    Do you hear any clicks before it switches off?. Any display on switch on? I should have asked the obvious first. Have you checked the wiring at the back to make sure there aren’t any stray strands shorting?. Martin

    PIONEER CDJ MK 800

    Yeah, these have a bad name in the DJ industry. Fine for static work but not so for mobile. They are very fragile and as so, I would definitely recommend checking the connections. I can’t remember if these have a zebra strip or not. If they do, it could be the problem. As for the ‘caps lock’...

    Maker pro crevices ?

    If he did, he wouldn’t be asking!. You sound like my ex wife. “I lost my keys”, “where did you leave them?”. “If I knew that, I wouldn’t have lost them”:)

    Information on purchasing electronic components

    Where are you in this small world?. I use a high street shop and the big guys like RS components. I found by accident a good electronics shop in Cricklewood Broadway while working there. I use them now and they post it to me. Sometimes though, it’s cheaper to buy 10 rather than 1 if you’re...

    Trouble converting from battery power to DC adapter

    I think that question was for me. Connect the DC adapter direct to the BLACK and RED, observing polarity!. Then you don’t need dummy batteries.

    Trouble converting from battery power to DC adapter

    Don’t use the dummy batteries. Go direct to + and - of the full 4.5V. Martin

    Trouble converting from battery power to DC adapter

    How have you connected the DC adapter?. Sounds like the on/off switch is in series with battery wiring only. What light is it?. Edit: When you toggle the switch, the light works. Does the light work properly on batteries?. If not, the switch is faulty. Martin

    How to fix TV-BOX problem

    Yes, I agree it’s a little ambiguous, but I’ve never known hardware of any kind to contain an unzipper/extractor software. I would unzip/extract the ‘zipped’ files to a blank formatted drive. Then try again. I could be wrong, but it’s worth a try. Martin

    Help converting lathe from 110v to 220v?

    Yeah, the OP hasn’t responded for a few months but it seems like a simple enough reconfigure of wiring on the connector block. Martin

    Contacts?

    What about magnets in the ships and Reed switches in each grid?. Also a 5mm hole in the ships base and use the RGB LED on the board for it it sit on like a stand?. Martin

    How to fix TV-BOX problem

    Unusual for firmware to be in .zip format, I would have thought it would need to be unzipped/extracted first. Martin

    how to go from one power source to many power sources

    I thought this was going to be an oscillating amplifier for magnitude and amplitude.

    @dragon Where are you from? And located?. I’m trying to work out if English is your first language. Because you seem to understand something that nobody else does!. I’m just curious. Martin

    how to go from one power source to many power sources

    I’m baffled and discombobulated. What does that schematic do?

    My son's toy car exhaust sound :)

    Change the amps volume pot and use a sliding pot. With a bit of engineering, you can get the slide pot to work in conjunction with the accelerator pedal.
