I'm nearly through my stock of Rev3 boards and close to another order. There was an issue with the LEDs glowing a bit when the battery was fresh. Two red LEDs in series on a fresh batterie just wasn't enough of a voltage drop. So I sat down and added 4 more 0805 resistors and rewired it completely. Now it should definitely not glow dimly in a "supposed to be off" state.

The SAO connector was moved to the bottom center, but I was too lazy to redo the OSHpark upload - png download cycle again.

I've added a little smd / smt 2x2 header to the badge for future boards, kinda liked the idea to power boards over that instead. Just don't solder the battery holder and the clip and everything should fit.

Recently on twitter Jon Raymond asked about a firmware update for the older versions of the badge. My hesitation was big until this point, since I thought the charlie-plexing would take up too much space alone, to integrate animations like I did with the newer 0805 version of this badge. As you can see here, I've logged a bit about the progress over on twitter https://twitter.com/davedarko/status/959491261903310848.
I was able to put 7 animations onto the badge! If you want to try out some other animations on the push of a button, you now can!
added 7 animations, cycling through on push of a button
removed digitalWrite and pinMode functions and replaced them with setting appropriate registers
converted every int to 8bit / 16bit unsigned integers where I could

Oh help me Michael Knight! So this started yesterday and I just finished a box of 20 "badges" (gotta be careful around here what to call badge and what not). Some conclusions for the next badge, if I ever tend to be so crazy:
only do ten at a time
change footprint to 0805
there's a spare pin that could run through some modes (fast, slow, pov)
Change to two leds per pins
I stole the idea of processing from tymkrs.com where they put together 10 badges at a time with the help of a lazy Susan. Pretty cool idea and it worked great (unless I forgot I can rotate the assembly line).
So 7 hours of production and I was able to take this picture:
Now I'm off to @Tindie and see that I can put up a store etc. I don't have 0603 resistors for kits yet, once they're here I will put up kits as well. Any tindie tips?

And for the money I've bought some more boards, this time black pcbs from dirtypcbs.com though - sorry to every other vendor, but please add eagle brd file support :D Anyway, I wanted to have some black K.I.T.T.s with red LEDs as well.
