As always we're sponsored by PCBWay.com/?from=atomic - I'm waiting on some components so I can solder up the latest set of boards so I thought we'd do a bit of a hack on my old wireless keyboard.

I've been getting fed up with having to swap out the batteries for fresh ones, so I've made it USB rechargeable - just like the new fancy ones you can get from Apple nowadays.

It works very nicely.

Special thanks to James Sharman for the SMD soldering footage - you can check out his channel here: youtube.com/c/weirdboyjim

And if you're interested in how a SEPIC converter works, this is a pretty good video: youtube.com/watch?v=m5OG_3-sbCs
