I have quite the collection of Raspberry Pis and Pi flavored accessories. The new Pi Zero is right up my alley in terms of cost, size, and power consumption. It's so cheap, I don't mind soldering something onto it and devoting it to a project. One of my Bs is pictured here soldered directly to a screen, along with my A+ and Pi 2:

I saw the page that announced the upcoming Pi Zero contest just a few days after mine had arrived in the mail. There's not any real details yet, but I know I want to make something with this Zero, so hopefully February 1st will bring my project into more focus.

So far, my idea is to make a Gameboy Micro form factor device with a small screen, inputs (buttons and maybe a PSP joystick), and a battery. Tests with my A+ a while back say it should be able to at least emulate up to Gameboy Advance, which is perfect for me. As you can see above, the screen is just about the same size as the Zero board. I might even need to find a smaller screen to drop the size of the finished unit even more. But for now I have bigger problems: I can;t get anything to work! I tried hooking up various things I had lying around, but the Xbox 360 chatpad wouldn't work after hours of fiddling with it. There's a great tutorial with drivers and a step-by-step walkthough for installing it from the command line.

The last install script game me some errors, but a Google of the error said it wasn't important and it would be fine, but no dice. So next I tried this screen I had sitting around, thinking it would be easy because Adafruit had a nice tutorial on it. They even had a preconfigured disk image that ran Jessie, just like the Zero wants! The image wouldn't even boot for me, so I tried the long way with still no luck. I think tomorrow I'm going to try to get my little 128x64 OLED screen working with it. Maybe I'll have better luck with that. I'll keep you posted!!!
