So I sat down and poke around on uCs today for proabably the first time in a month. I didn't necessarily get a lot done and probably spent more time reading wikipedia pages than programming but, at least I feel as though my mind is directed for having a little gadget ready to show off at notacon. I think what I'm going to try to make is my own compact 'digital mode' transmitter that will be able to transmit text data and images over a short range using a toy fm transmitter. Through hours of poking today, I found a good library for sd cards that supports the badgeduino hardware I want to use. It also includes a uart module for easy troubleshooting.
The remaining tasks are;
Get AVR sending tones
Get AVR sending KCS (cassette data) tones
Successfully record and decode data (I had all this done before; the code must be somewhere?)
Feed data from sd card to tone ouput
Integrate FM transmitter
Build badge shield
Sorry, this is a bit scattered, I'll repair it later.
Sleep.
