Push to Reboot

A power strip controllable via DTMF commands issued using a handheld radio. My original goal was to provide a way to reset network equipment while away from home.

Since starting the project I have cleaned up my network and no longer experience device lockups. I gave it some thought and decided to defunct the project as it requires legacy equipment to build and has timing attack issues at the protocol-level.

I keep the project listed here because it can be used as a reasonable starting point for other AVR GCC projects. It also contains a memory-conscious implementation of HMAC-SHA1 that may be useful to someone.
