Hi all
I first did a test stand about 10 years ago using a dataQ but I have never been fully satisfied with the result
I done a new one in the last few weeks which seams a bit more promising
It is using an stm32f103c8t6 board and an HX711 board so it is quite cheap to make. I am using an 24LC512 to store the thrustcurve and some bluetooth or telemetry to do telemetry.
Recording is triggered when firing the motor. It can record 41 measures per seconds. And can be calibrated using the application to use different load cells
test stand can be configured using an Android device and do things such reading thruscurve or flashing board firmware
application is in English and French
code can be found on my github
