More hardware,... for now.
I thought about using my ANT+ sensors to calculate my speed/distance, but my garmin hub sensor only works accuratly when combined with GPS ...so sinc I'll be training in the basementon, on a "stationary bike" .... no GPS data for me.
Therefore I built a sensor to get the data I need.
I'm using the the flywheel from the bike trainer and a CNY70 (Reflectic Optical Sensor) to calculate my speed and travelled distance.
Here, my "minimal-invasive" version of a sensor fixture.
First test on how and where to put the sensor. I'm shooting from the hip here,... (no plan made previously)
Sawing and bending the aluminium profile
Drilling and cutting the thread on the counterpart
Finding the right position
a little bit of hot glue to position the sensor
fine tuning for minimal distance
