The electronic portion of the device primarily 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 it’s turned on and to give it an extra sense of presence when it’s in your hand.

The following project its a basic thermometer that can measure data from 2 sensors, for example you place one sensor inside the house and another one outside. The schematic is plain simple DS1621 or DS1631 digital temperature sensor and a bunch of resistors and diodes. You can use smd parts or trough-hole, it doesn’t really matter but if you want to keep things small and cool, i suggest you use smd. Also on the pcb you will solder a DB9 connector so you can stick the small pcb directly into your COM port. The measurement is than showed on the windows taskbar.

POV is a really cool concept, similar to the way a television works, an image or series of colors is spewed out and ‘blend’ together because the light pulses occur at a speed faster than our eyes can properly observe. thus like a camera with a long exposure, we see a blur and this blur can be made directly into an image of your choosing.

This project is for a small electronic unit that allows the user to sense the presence and relative signal strength of wireless hotspots. It can be worn as a pendant or carried in a pocket. It is “always on” and communicates the presence and signal strength of an in-range hotspot by way of sequences of pulses - like a heartbeat you can feel. The stronger and faster the “heartbeat”, the stronger the wireless signal detected.
It does not actually authenticate or otherwise interact with a hotspot in any way. It is a 100% passive device, meaning it transmits nothing. It can detect hotspots, but cannot be detected itself.
I never thought you could use a plastic Easter egg as a headphone holder for an iPod, i must say the idea is really original. I know that by the time you get to this word you’re already thinking that this is a boring idea. Boring or not, its still useful, instead of wrapping your headphones around the iPod and damaging them in time, its better to keep them inside an easter egg, and keep them safe.
