Ketan Desai just posted photos of his exciting DC-DC converter project that squeezes an After Dark PCB into a TO-220 package:

Got the boards in from @oshpark and got them put together! I’m pretty happy with how well they work. Its crazy that the silk is so sharp when each letter is less than 1mm across!

Thanks @BenSommerf for taking some sweet macro shots of these!

Pretty impressed at how well hot glue picks up the super tiny chip markings.

The renders of the project were pretty amazing too:

Decided to try out one of these integrated DC-DC converters. The small size means I can make it a drop in replacement for a TO-220 LDO. The @oshpark order is in! pic.twitter.com/Z4d8qgyHkd
