How about a wireless RC car in a friend's living room in say Germany, operated by a girl in New York (or San Francisco). Should be simple: girl uses keyboard to transmit instructions through German friend's computer. German Friend has a wireless transceiver that communicates to the RC car. How does she know what instructions to send? Easy way is Skype. Creative way are sensors, even cameras on RC car that comunicates back to her in NYC!

  • Here's something I've wanted to do for a long time. It's funny, or more like totally zany. Imagine, if you will, a pair of sunglasses. Preferably big, round sunglasses. We make them with polarized lenses, being careful to align the polarization at the same angle in both (fixed) lenses. Then we have another set of polarized lenses in front of the two fixed lenses. Now imagine we have a motor, and a drive belt or gears, or a chain that will turn the two front lenses. We mount a photocell somewhere on the earpieces such that it looks forward though the lenses. When the light through the lenses changes, the photocell detects it, and the Arduino (preferably a very small one), drives the motor, letting in more light or less light. As the wearer turns his head, the lenses react quickly (and perhaps a little audibly), to the astonishment on onlookers. I visualize them as somewhat "steampunkish" in appearance.
  • Solar panel array tracking monitoring system. Monitor the voltage, current, and temperature from each solar panel in each of several arrays. Each array is mounted on a post with linear actuators and light sensors to move the array towards the sun. The system will use low power bluetooth and WiFi to interact and store data as well as activate virtual meters. One of the issues to be addressed is the control of several Arduinos. Can Arduinos be daisy-chained? Will software coordinate the several micro-systems. The design is intended to be modular and expandable.
