after assembling a PCB for 3h you owe it to yourself to make it look nice xD

It is not a cinematic masterpiece but I think it shows how the device works.
Full list of functions: (“trip” values can be manually reset to zero)
- total distance
- trip distance
- range estimation
- power use/regen
- total Wh regen
- total Wh discharged
- trip Wh used (discharged-regen)
- trip Wh discharged
- trip Wh regen
- speed
- Wh/km trip
- Wh/km total
- driving time
- power cycles
- max. speed
There is no “save” function. Data will be recorded fully automated and is stored in 3 redundant sets over the whole 256Byte FRAM page.
Controls:
Push the wheel to the left or right until the buzzer sounds. Repeat up to 4 times to reach the requested function. The buzzer tone’s frequency will go up respectively.
After keeping the wheel centered for 500ms the requested data will be beeped out.
Holding the wheel to the max. left/right position fir 3s will reset the trip (left) or also show data (right).
The “positions” of the data can be set through the software PC tool.

New hardware version incoming!
4 layer PCB, only parts on the front for better mounting.
Fixed some stability issues.
JST-PH-2.00 connectors for the ESC and also to optional external buzzers outside of the enclosures.
