# coffee-scale
|
|
|
|
Building my own coffee scale that is tailored to brew over coffee and also has a beeper so your ADHD brain won't forget
|
|
the coffee during the 30 second blooming phase...
|
|
|
|
## Harware
|
|
* RP2040
|
|
* HX711 with a load cell
|
|
* SSD1306 display
|
|
* passive piezo buzzer
|
|
* simple pushbuttons
|
|
* ToDo: LiPo battery and charger
|
|
|
|
## Build and flash
|
|
```shell
|
|
ampy -p /dev/ttyACM0 put libs/hx711.py
|
|
ampy -p /dev/ttyACM0 put libs/ssd1306.py
|
|
ampy -p /dev/ttyACM0 run main.py
|
|
```
|
|
|
|
`run` is just `put` followed by a direct execute of the code.
