Bricked! ATTINY2313 Repair with HV Rescue Shield

Summary

This blog post contains my build of a "HV Rescue Shield" by MightyOhm.  The High-Voltage Rescue Shield is a high-voltage programming shield that fits on an Arduino.  The Rescue Shield works on 28-pin ATMEGA ICs and on 20-pin ATTINY2313 ICs.  My use/instructions for now only concern resetting the LFUSE (clock fuse) so that the IC can be used with a 16MHz crystal.

Introduction

I bricked my $3 µC IC on my first attempt at programming.  Recently I found some DIY AVR HV programmers that could be made from stuff in my lab.
