Blink Box Box
Bilnk Box Box designed by Craig Hickman.He used a Roland CNC milling machine to fabricate the case out of 1/4โ€ and 1/8โ€ acrylic scraps. This project consists of a do-it-yourself Arduino driving 10 LEDs.The LEDs change flashing patters whenever the luminosity level dips below threshold. This lets you change patterns by passing your hand over the device. It also contains a cell phone vibrator to let you know itโ€™s turned on and to give it an extra sense of presence when itโ€™s in your hand.
