I made engine tester based on arduino. I would like to ask you, if someone/something does exists ? I found only too expensive commercial project: https://www.rcbenchmark.com/.
My cost only few $$ and I dont know if Im missing something. Here is what Im doing:
(ACS712 20A, resolution 40mA) on ESC input, current measurement is tricky - the value is really unstable so Im doing averiging from 300 values but still... it needs improvement [$2]
So I can calculate:
I used Arduino UNO copy with LCD + buttons shield [maybe $10 ?] + extra potentiometer. There are two modes:
My motivation is compare ESCs, motors, propellers to get best combination. The tool is mounted on my table during measurement so there is a lot of space around. I know it is not exatly as during real flight but still, it is good to compare.
Are you interested in or am I doing something what exist or is useless ?
btw sorry for my english..
