TinyLEDs

We built them quickly and didn't connect all the pins needed for the accelerometer. Later designs will correct for that.

The Freescale chip supports 5V, but no economical accelerometers support such high voltages. We are trying to exploit properties of the i2c bus that 3.3v is likely readable for the microcontroller.

When we made the first symbols we used the smallest circle we could generate that 'looked' like a circle. The Peace symbol is about twice the size, but it is again the minimum to convey the symbol.

Trying to keep the boards small helps to keep them cheap as well as versatile. We will experiment with various uses in jewelry and will seek consumer feedback on the concepts.
