Hacking the Newest Ride of the Fleet - Wahoo Kickr V1 2014

 Craiglist got me again. Picked up a Wahoo Kickr V1 2014 after borrowing TO's V4 - there is a bigger difference than 3 between these models, namely Wahoo wants nothing to do with the V1 apparently.

I have been spending a lot of time not on a real bike, in Zwiftland, getting soft and fighting depression. Healing I guess, missing yet another big chunk of my life as if was Covid2.

Check before the CL purchase, Todd. This happened with the Faraday too, I tend to jump at pretty, though dead, technology.

The V1 "works" but way undereports power. Wahoo let me know the firmware won't be updated by them at least, then confirmed hardware is broken if the speed is not reporting

After way to much obsessing and searching and even joining Reddit and Discord to find info, I got out the tools to find the PCB board. It turns out there are 2 - the power controller one is opposite the heavy flywheel, the "brains" were hiding all along up near the optical sensor near the top axle.

A video on YouTube is here that gets one to the boards fast: Wahoo Kickr V1 PCB Board Location, Removal and Survey

Some stills are below, and I will start inventorying the chips and parts.



















I am thinking it would be most interesting to use an Arduino or Raspberry Pi to replace the "brain", maybe skip the optical board altogether.
