CG Scale Heltec wiFi Kit 32 with Oled screen and charger

thingiverse

A redesign of the classic CG-Scale. For me the base was a little bit to small. As well I wanted to have a Helted ESP32 that enables the scale to connect via WiFi to a computer and interact with a Windows app. I wanted to have a hassle free installation and setup of the scale. But flashing the ESP still needs some knowledge of Arduino. Shematic will follow as soon as i have done it. But the code already explains where to connect the loadcells. I used a 1S Lipo cell. It is charged as soon as the USB cable is plugged into the computer or a wall charger. I managed to bring the ESP to sleep, but still the current consumption is quite high and fully drains the cell after a while. So I decided to remove the ds function and added a switch to be able to disconnect the battery fully. Please treat this as a first off, for sure it is not super documented. But if you dig a bit into it, it should be self explanatory. Update 16.01.2021 A bug was found in the APP where L1 and L2 were swopped. The fixed App can be found in the attachements now. Update 30.05.2021 Aa a lot people asked for it I made a shematic and attached it.
