DIY coffee scale / load cell controller.
Video of it in action: https://youtu.be/54p8B-DXDt8
Whey v2.0 is a wireless 2-piece hardware that is separated between the sensor plate and the display screen. This project currently uses 500g load cell, with ADS1232 analog to digital converter. It uses ESP-Now to communicate between each microcontrollers. More specific information are available in each directories. The story behind this are available in my blog, everything is linked all the way back to the very first iteration.
- No battery indicator on the plate -- I just have a powerbank ready when it's not turning on
- TFT_eSPI library only works with the one from TTGO T-Display repo, but won't compile when using the latest one by Bodmer.
☐ Battery indicator for the plate?
☐ Make another plate with 3kg load cell
☐ Add support for multiple plates (at least 2) to screen
- 29 Dec 2021: Officially release v2.0
- 19 Jan 2022: Fix so the low batt indicator doesn't blink when the voltage is right on the edge
