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.
The amplifier was designed with an early version of Agilent ADS, PCBs were fabricated on Rogers 5880 (Duroid), and we hand built several prototypes on K-connector fixtures that Tony designed. Measured results were consistent with our simulations.
Tony and I won an award for this project at the Eureka! undergraduate research conference in June 2000.
I heard recently that this project is being used as an example of a good EE senior design project at other universities, so I dug up an original copy of the paper we submitted and posted a PDF here.
