Hi Gang. Long time no see; I kind of lost interest in flashlights and the like so I haven't had anything worth posting about here at CPF. But I've recently been working on a something that several of you might be interested in building for yourselves.
Lately I've gotten interested in electric powered bikes and scooters, (Mostly I blame Darell for that) and am in the very early stages of building a few different designs. And of course one of the critical components is the battery pack, and I want to be able to build my own without the danger of damaging cells by soldering them.
So, I decided to try my hand again at building a Capacitive Discharge spot welder , And have come up with a design that works fine and is of nearly insignificant cost. Even if you have to buy just about every component, you can build your own functional unit for $100.00 with just a little shopping around.
A lot of you that are into making your own stuff will probably have most of the components needed already.
I'm not going to post all the details of it here, but I have a pretty extensive and ongoing documentation of text and photos (and soon a video or two) over at the ledhacks.com website, to which I will be adding as I refine the design.
Here is just a teaser:
