sebastianpsm / orc Goto Github PK

Orc was started during the corona pendemic and the time where it wasn't possible for me to go rowing. The basic concept: Use available electronic parts (e.g. from Reichelt Elektronik) and a 3D-printer (service) to create a good and solid rowing computer for the day-to-day-training.

The system consists of a microcontroller, SD-card, 9-DOF-sensor, e-paper display, a li-ion battery and charing electronic.

• Electronic parts working together
• 9-DOF-sensor software works
• e-paper display software works
• Logging to SD-card works (result is stored as csv file)
• Bluetooth works
• charging works

• Design, build and test a housing
• Add a voltage divider to show the battery state-of-charge
• Use Bluetooth to publish battery status and SRM (strokes per minute) value
• Use Web Bluetooth to show orc values like battery status and SRM

• The needed electronic parts can be found in the parts_list directory. Currently theres only one parts list for Reichelt Elektronik available.
• More information about the first version of the housing will be uploaded soon

• Display
• ESP32 Module (espressif esp32-devkitc)
• 9 DOF Sensor
• Charger
