a small demo of the scale accuracy.
It used a hx711 and 4 x 10kgr load sensors off aliexpress, the hx711 runs from battery voltage. I used the nordic PPK2 to test the hx711 at voltages from 3 volts to 4.2, readings were not affected by voltage, I read online that the hx711 modules are 5v only, but testing says they work fine from 3v upwards.
there are tree BIC lighters in the video, blue=empty, green =almost empty, yellow=brand new.
The scale is stable and can accurately tell which lighter is the full one, amazing espruino, I thought it would half work, instead it is the best scale I have in the house.
