10M Balloon Beacon

This is an AVR based project of 10M CW balloon beacon, the beacon can send information besides ID in CW, like battery voltage, temperature. Here is the schematic in GIF format or PDF format, and this is a really simple source file for AT90S2313 to send ID in CW, can be easily modified to fit AT90S1200. The Frequency is about 29.491MHz, output about 0.5 watt. I am still working on this project, so stay tune!

A Simplified AVR ISP programmer

This is the simplified Diagram of the original AVR ISP (STK200/300) parallel port interface. It is very simple and low cost. The software can be download from ATMEL or PonyProg, I personally strongly suggest you use the software of PonyProg, because it almost support all of AVR MCU including the brand new ATMEGA8, ATMEGA16, etc. :)
