Design for A Cause 2021Trakcore #1 AI Assisted Posture Modification - Project Introduction
I've described in my previous blog Trakcore #5 AI Assisted Posture Modification - Using Cordova Bluetooth (BLE) Plugin to Connect Arduino Nano 33 IoT with Android Phone steps to build an Android app, which can communicate with MCU. Now I need to validate the app and embedded code in a real-life working conditions.
It will be great if Arduino Nano IoT 33 had a wearable accessory available. I was not able to find any. So I came up with my wearable design requirements for Arduino Nano 33 IoT, which should support the following.
- I can clip it to my back
- I can walk with it
- The device should support at least a working day without recharge
- I can easily recharge it without disassembly
- I can easily reprogram it without disassembly
- LEDs on the board must be visible, so I can check its state
I've decided to limit myself to materials which I already have to eliminate risks of delays due to supply chain constraints.
I've used the following materials and tools:
- USB Power bank
- USB cable
- Plastic from a packaging
- Foam (came with MCU)
It took me around 15 minutes t cut and connect all pieces.
Here is the result
Findings and Future Improvements
Here is my findings after several hours of usage:
- Easy to use
- Not reducing my range of movements
- Nerdy look
- Smaller battery
- Magnetic clip
- 3D print
- Smaller board
