Ok, just a quick update about this little project.
First of all, a big Thank You to Hackaday.io and all the judges that thought this project was worthy of winning a Pi Zero! And a congratulations to the other 9 winners https://hackaday.io/contest/9326-adafruit-pi-zero-contest/log/32973-winners-of-the-10-pi-zeros
I have now sent off some new gerber files for an updated PCB. This gives more mechanical stability to the Pi Zero and fixes the composite output and should be in my Tindie store in a couple of weeks time.
Due to the limited supply of the Pi Zero, some people have asked if a regular non-Zero Pi will work. Well, yes, but no, well, kind of. Physically, it won't fit as the USB ports obscure the PCB - even without the composite socket (which you wouldn't need anyway)
However, if you used extra deep header sockets, or if you were to unsolder the header on the Pi and mount the boards back to back, then it would - although mechanical support would be a problem. Running jumper cables over to a Pi would work fine though.
Then install and run Screen;
sudo apt-get install screen screen /dev/ttyAMA0 115200
And you're good to go!
