OPEN SOURCE: "MAGIC" Polarity Correction
I want to make some of the neat things I've created over the years available for others to use/enjoy/ignore/whatever So I've decided to make these neat creations open source, and am releasing the Eagle schematic and board files. They're free for anyone to do with as they see fit!

These are the "magic" polarity correction (not just protection) driver add-on boards that I teased here:

and that Benmw (through CajunLasers) had for sale, discussed here:

They only use component, an IC called the DMC3021LSD. It currently sells for 68 cents on Digikey, and you need 2 per board. The circuit is similar conceptually to a bridge rectifier. However, these don't drop voltage the way bridge rectifiers do (they drop only around 60 mV per Amp).
The IC can be sourced here:

Enjoy!
