Description
A redesign of the classic CG-Scale. For me the base was a little bit to small. As well I wanted to have a Heltec 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.
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.
Update 19.03.2023
The software is made to run on a V2 Heltec. As the V3 has a different pinout the code needs modification prior usage.
