HV Rescue Shield kits are (finally) back in stock! You can order one here.
Holiday sales are picking up and shipments of a few critical components are just now arriving. As of today I only have a few Geiger Counter kits left in stock. I expect to sell out within the next few days, but should have more kits ready within 2-3 weeks.
International customers – I recommend ordering now to guarantee delivery by Christmas.

PS: Rescue Shield kits are running low as well. Once I sell out I probably won’t have more before early 2015.

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.
