To start off, thanks to the video sponsor: JLCPCB for sponsoring this project. $2 for 1-4 layer PCBs, PCB assembly from $0: jlcpcb.com/DYE
In my recent projects moving to the Attiny series of microcontrollers, I've found a need to be able to reset chips I've accidentally "bricked" through incorrect fuse settings that prevent low voltage serial programming. So in this video we take a look at a pcb I designed based on work by Paul W (rickety.us/2010/03/arduino-avr-high-voltage-serial-programmer/) and Jeff Keyzer (mightyohm.com/blog/2008/09/arduino-based-avr-high-voltage-programmer/). Huge thanks to Paul and Jeff for their software and hardware which this project wouldn't be possible without.
In this project I've added to the design to make the unit standalone by utilizing an OLED display for status info and also integrating an interrupt based closed loop PID compensator and boost converter to generate the 12V high voltage required to reset attiny chips. This way, my board is completely standalone and only requires a 5V usb power supply to operate.
Board files, modified software and detailed writeup available on the Hackaday.io project page here: hackaday.io/project/184867-attiny-high-voltage-fuse-reset-er.
