I sold out of Rescue Shield kits just after the holidays. Fortunately, new PCBs and components arrived last week. Hooray for no back-ordered components this time! What used to be the norm is now the exception. (Technically, green LEDs did ship a week later than the rest, but as I was still busy soldering boards it didn’t affect the overall lead time to produce kits.)
I’m happy to announce that kits are back in stock now.
The Rescue Shield is a 100% open source, Arduino-based high voltage mode fuse programmer for AVR microcontrollers.
It allows you bring an otherwise “bricked” or misconfigured AVR back to life by editing the configuration fuses that control the operation of the RESET pin, the internal oscillator, and other features of the microcontroller. The Rescue Shield can talk to chips when ordinary ISP programmers can’t.
Not content to simply duplicate my work, he added a few creative twists of his own, including a custom handmade case made of alucobond, MDF, and real wood veneer that gives his finished radio a nice, modern look. Inside, a hacked WL-520gU wireless router running OpenWrt runs the show and an ATmega microcontroller programmed with BASCOM interfaces with a rotary encoder and graphical LCD display.
The very impressive result is shown in this video:
