fresh new (not yet working) version on the top left I call "Kürby", since it's orange with a green top - a pumpkin in German is "Kürbis" and it almost sounds like Kirby. 

Can't tell why it's not working yet, but also am tired and want to clean up the desk...

Well that clean desk motivated me to check my AP2112K layout on my Rev2 board - let's say that escalated quickly :D Found out that my enable pin was connected to the switch and the other side connected to VCC, not VREG_IN. There's no VCC to turn on VCC :D luckily it's just a bogde wire and a little cut, if anyone bought this.

Lovely colors, all of them. How long did you plan doing that pumpkin one? You must have ordered the orange buttons...

Well that was more a "hey, colored buttons, I'll take, orange, green, red and blue please, Mr. eBay Store" some weeks ago. The orange case was printed right when I got back home, since I thought it would fit the purple boards. Then I wrote the Aisler review and thought at least one board should be made, although it's two revisions old now. So there's that :D I'm planning on ordering a nice neon pink filament, since I can't get pink pcbs ...

How many revisions did you do already?

currently on Rev3, Rev2 is on the right side but the slots are missing on the boards so I'm tempted to only test the power section, especially the AP2112K since the adapter board I made for Rev2 didn't work out. The regulator is already on Rev2, so there's that. Rev3 will have footprints that accept anything from 1206 to 0603 passives. Then *maybe* there will be a Rev4 one day with sound on it, but maybe there's a complete different handheld coming instead. Not sure.
