Thumb lights (TL10, cr1 for a package of 10)
These are 0.5mm thick, 4mm x 4mm transparent plastic with one side covered in sticky substance. They come on a sheet of plastic that lets you peel them off one at a time as desired. Each one has a small battery, a pressure switch, a small microcontroller with a Bluetooth style radio and an array of microscopic LED lights.
Normal usage is to stick one to your thumb nail. Pressing on the thumbnail activates different modes
Mode setup and what pattern of presses selects the mode are done with a hand computer app.
The default mode selection is a long press to turn on or off, and taps to go to the next mode
Modes are set up as color, intensity, blink pattern. For example, the default options are;
White, 100% bright, always on
White, 50% bright, always on
Red, 50% bright, always on (save night vision)
Red, white, 100% bright, alternating colors every 0.25 seconds
Red, 100% bright, SOS in Morse Code followed by GK in Vilani version of Morse
The devices have enough power for 8 hours at full bright, with corresponding increases in battery life if the mode uses fewer LEDs or is at lower intensity. The red/50% mode (the longest running default option) stretches to about 33 hours
When the battery dies, a chemical is released that causes the sticky to fail, and it easily peels off the thumbnail
