Laptop Powered E-Bike

Ok, got some goodies in the mail, including the isolated power supplies I was waiting for!

Also got a few other things, but those are for other projects. I did some soldering, and of course, I had to do a brief household power test with my fingers (yep, still works). Anyway, I got my little test rig put together.

So 120VAC from a boring old plug to two 120VAC to 5VDC isolated supplies, then to two TP4056 charge control boards to two cells hooked up in series. So far, no melting or burning or smoking. I still need to charge them up and make sure the TPs behave properly, but so far so good!

Also, I was removing some old, unused conduit from my house the other day, and found some old Type TW wire inside. No good to reuse as household wiring, but at 12 gauge (about 2mm) it will make good battery wire. I did the razor blade in the vice thing to get the insulation off. Then I had to clean of this oily stuff coating the wire itself, but I got several meters, which should last me for a few small projects.

Very slow progress, but still progress. Smile
