    Charging Li Ion batteries.

    Ah, good ol' Dave. Yeah, I think that gave me my answer. Unfortunately to questions I didn't know I had to ask. Which now leaves me with a pickle as to whether build proper kit which may come to naught if the pack that someone else tossed, and I don't actually need, is junk- or put it in the...

    What tool do I need?

    That entirely depends on the phase of the moon, lol. Quite a bit also depends on your skill with the tool. What are you soldering/desoldering tomorrow morning? I went most of my life with a bog standard Weller 40 Watt stick for almost everything PCB including early surface mount, and carry a...

    Charging Li Ion batteries.

    Well yes, if I had the proper charger I would be using it. If the pack isn't buggered, I'll look into building a proper charger. If it is buggered, I'll tear it down and do have a charger for individual 18650 cells. I'm just wondering if pounding 3/4 of an amp up the butt of a 5AH pack at...

    need help repairing 2006 "Zoundz" toy - broken rfid

    Hmm. That coil in the picture didn't scream RFID and I did a quick google on Zoundz, YouTube return. If I'm not mistaken, you place a piece on a mother ship/board and it does something? The actual game play not clear. Your pictures as I see are of an electronic bit. The chip - or brains - is...

    Hi there!

    "When you do ask questions, you may look stupid. When you do NOT ask questions, you will STAY stupid." I like that! I build US Navy force protection boats and fire boats. I always tell the new guys, ask me anything, I will never think you're stupid for doing so. I believe in kindness and...

    Charging Li Ion batteries.

    Ask me about lead acid and I'll write you a book. But I have a Chinese 36V 5AH (on the label) Li Ion battery pack. I want to charge it and not die or burn my shop down. Eyeballing what's at hand: a variac, bridge rectifier, capacitors, multimeter, resistors, battery pack. So can I just fly...

    Driving 3p delta wound motor with H bridge.

    Hey. No particular project in mind, but just mulling the possibilities. I've scavenged a few motor/wheel assemblies - one from an E-bike, one from an E-scooter. Both delta wind three phase. No specs. Wondering how to build a controller (Yes, I know potted boxes are available online) over a...

    Hi there!

    My name is Jim, but you can call me Jimbo. I haven't been on a forum since Dutchforce went dark in '15, but I kind of miss the world. I can hold my own on a breadboard, but I certainly don't know near everything, and often have 101 questions. I let the magic smoke out occasionally, but that's...
