DC Rainmaker who once said «science sucks» did some «Treadmill Accuracy Testing Fun» in the following video:
this is the title of the above review. And fellnr uses a high speed video camera and the Kinovea software for treadmill calibration:

Christian Galeffi has built a Raspberry Pi treadmill sensor:
But then he sends the sensor data over ANT+ up to Zwift so that we cannot access the sensor raw data from his project. This was all very strange for us personally. Now we know why DC Rainmaker said that science sucks. If we as scientist look at treadmills, we have found out that a Xiaomi WalkingPad A1 which can be bought used for about 250 USD on eBay is eventually only a toy for treadmill enthusiasts. And scientists who played with those like this have built «toy treadmills for medical doctors» which costs 10 00 USD.
A device which is not a toy and can be used by scientists is the GE Marquette CASE Stress Test System which costs $ 13`249. But we still think that it is possible to build a GE Marquette CASE Stress Test System alternative for about 10 % of these costs with the knowledge we shared here.
Science about treadmills sucks, since if want to buy a treadmill to do science with it it costs 13`249 USD. And if we want to build one for 10 % of this costs it is a lot of work for scientists like us.
