Would it be possible for you to make one of these for me? at a reasonable cost? And calibrate it.etc....I am wanted to test small BP Estes motors..... I would be willing to pay you for the parts, and the time to build ,test and calibrate it. let me know if you are interested

Incredible project, can I use a higher capacity load cell with this same configuration and code?

I'm trying to calibrate the 5 kg load beam using 20, 30, 50, 100 and 150 gram total weight. I have tried and I keep getting 0.00 for a Calibration value. When I save it to EEPROM it keeps displaying "Load_cell output val : nan" What is going wrong?
