    Power supply for CB

    Harald, was my assumption correct about shorting the output leads?. I don’t want to give false information. I just remember my son’s friend at university not being able to set current on his. But his was a £30 unit from eBay, this one seems rather pricey for what it is!. Mine is programmable so...

    Power supply for CB

    I do believe that shorting the output leads is the way to set current limit. If you set voltage to approx 5V, then clip the output leads together. The CC knob should now be active. Set Current to 4-4.5A and then separate the leads. Now just set your voltage to 13.8V or similar. If the current...

    Help with reading an LED Datasheet

    Hi Jamie, if the LED is too bright for your liking, you can of course lower the current. Modern LEDs are still very bright at 5mA. Martin

    Power supply for CB

    Yeah, sorry. Typo of 13.2V. Should have been 13.8V. Thanks @bertus . Martin

    Power supply for CB

    Have you got current limiting set? Set it to max. Plus, my old (linear) CB supplies were 13.2 Volts. Martin

    DVD drive to usb

    These adapters work perfectly fine. I use them for external HDDs, DVD players and even a floppy disk drive!. I have several of these adapters for SATA to PATA etc. Have a read of this. Martin

    Help with pin connector identification

    Good idea, they’re not expensive. You could always add your own connector type if you don’t mind opening the unit and changing them? Or hardwire to inside and have external connections?. Just another idea. Martin

    Help with pin connector identification

    Do they lock in and pressing the plastic lever above, unlock them? The ferrules that @Kiwi mentioned might well work better than banana plugs. Martin

    Help with pin connector identification

    Ah ok. That unit doesn’t look like it has banana sockets. Did your original wire and plug come with it from new?. I would think somebody on here can tell you what connectors/jacks your unit requires. Martin

    Help with pin connector identification

    Has your device got ‘female’ banana sockets? Too loose? You can open them up a little by spreading the blades out. Quite common for older jacks. Banana plug and banana socket. Martin

    capacitor replacement help

    My apologies, I don’t mean to sound horrible, but reinventing the wheel is pointless. There are countless crossover calculators online which do a reasonable job but as some have already told you, simulations and real world tests are somewhat different. Having flying leads out the back of the...

    Change timing period to gadget ?

    Hiya, Look up bigClive on YouTube, he did a few videos and reverse engineered several of these non contact pen types. I just looked and found one but it wasn’t your type. Go through his videos and have a look. He definitely has a couple of vids. Martin
