Next steps:
  - write firmware that gets motor instructions over http
      - check motor driver parametrization
      - think about data model for motor driver
      - give sensible hostname to testdriving system
  - manually start a test cycle and view in app
  - for debugging write a python logger that shows current state in a graph (live)
    and prints live prints the current logs
     
{"speeds":[-0.1, 0, 0.1, 0], "durations":[500, 1000, 500, 1000]}

{"speeds":[0], "durations":[10]}




Test could produce a html report with graphs and tables


Short physical test:
--------------------
  Sequence:
    - start session
    - phase 1: no load
      - check sample rate
      - check min/max values
      - output: graph, min, max
    - phase 2: 
      - periodic loading/unloading
        - about 20 cycles
      - run peak detector, compute cycles
      - output: graph
    - stop session
    - download session
