We're not really hung, but it is taking a while for us to decide just who get the title. While we decide, here's a couple more entries remind you what it's all about.

[Razvan] sent in this excellent entry. (I'm hosting it on my personal server since he didn't have one)
The writeup could be a bit clearer, but the design is pretty sweet. It features a mega avr brain and a microchip ethernet controller with a software based USB interface. It's a pretty intriguing design - lots of possibilities for ethernet controllable projects.

[Tom D] sent in this rolling codes garage door opener. This will step through all the garage door opener codes for garage doors made before 2003.

21. Anyone know what LSP11 is for?

22. Also, I checked out the BOM and found that the 555 timer, the 12-bit counter, and NAND have supply voltages of about 5V. The problem is that there isn't any handy 5V batts around. I'm thiking of just addding a 1k resistor right after the +'ve terminal to reduce the voltage to 5V (assuming the current draw from the datasheets come out to ~4mA).

Can someone confirm the required voltage for the circuit?

24. I was wondering how to use these programs submitted by the two people? I've also been looking for the source code for hacking the garage doors
