1UP is a simple indicator of activity through the use of a Bluetooth LE link to your gyroscope/accelerometer-enabled mobile device. At any given time it reports one of three states:
- Low activitity level (flashing blue arrow only)
- You've met your daily activity average (alternating blue and green arrows)
- You are well over your daily activity average (flashing green arrow only)
With the generous assistance of Mr. Fletcher Bach, I etched my first custom circuit. It has two LEDs and two 220 Ω resistors. I surface mounted the components for a thinner profile. There are also three holes for pins to connect to the TinyDuino that I used as the microcontroller.
The enclosure is a small acrylic box with a cover of two halves of acrylic sandwiching a strip of wood.
Key challenges encountered:
- Form factor (difficult to make device as thin as I had wanted)
- Charging/power (could not figure out a good way to make the battery removable)
- Bluetooth integration (the development of the BLE link was far too ambitious for only a few weeks)
- How difficult it really is to design a wearable deice that not only works but is fashionable/aesthetically pleasing
After creating this device, I finally understand why the concept of wearables has been so slow to take off. It's an incredibly hard design and development process that requires knowledge in several very different fields. I now have more of a respect for why "failed" wearables fail.
