The video takes you through my struggle to make this mod work:
- looking at grounding of the unit
- getting the parts
- drag soldering
- Arduino
- ICSP programming and fusebits
- missing reference on the board
- only 1.1V reference in the 328p
- external 2.5V reference added
- still wrong gain.
See the previous update video for how I made it work.
