cheap-fuse-doctor

I'm showing two different high voltage fuses programmers here, they are:

Number one:

Resetting the fuses on a Atmel Attiny85 with a Serial High Voltage Programmer ( ... well a frightening 12 volts DC mind you ! )

Just some pretty printings, to help my failing memory, to an excellent instructable: Attiny fuse doctor.

I just added some code to print-out on the serial port, which Attiny(13, 24, 25, 44, 45, 84 and 85) the Doc has detected.

Thank's !

I like to add stuff like this in Github, just in case it disapears from instructables in this case or from other sources. I also added some pictures and fritzing breadboard and schematic views.

Number two:

Based on new Stuff from:

This is the simplest fuse programmer I ran into, so far. Instead of an Arduino it uses an Attiny85 as a master fuses programmer. I initially had issues with it, but it now works fine after I added 10 uF and a 0.1 uF between +5 and ground, as suggested by the author. I also added a 1K resistor on the base of the transistor. This version is showned in all FuseDoctor_Master_Attiny85 files and a copy of it's .ino file in AttinyMaster-Target.ino.txt.

enjoy !
