pretty cool effort!

My brother shared this with me this morning. What an excellent solution and as he said "yay for smart (and curious) people!"

I'm kinda hoping that someone does this with the original kickr. Apparently Wahoo can't repair them if the controller dies, which has happened.

Somebody needs to package this up into a kit with the Raspberry Pi in a case so sweat doesn't destroy it.

I'm not surprised to see this at all but was really surprised to see the bare circuit board on the handlebars and him saying he used it for 2000 "miles" and it was still working.

That's way harder... this guys is just reading the stuff the original controller is outputting on bluetooth and retransmitting it on Bluetooth in the more open format Zwift, etc.. can understand.

To replace the original controller would require doing all the analog electrical engineering again to actually talk to the sensors and figure out what the heck they mean.

In this article there sounds like there's a lot of magic in that part, like the way it outputs power based on a known brake force curve + cadence instead of having a real power meter.
