The purpose of this project is to build a device that measures acceleration/tilt on one axis (backward/fordward) capable of fitting onto the dashboard or hanging onto the window of a standard car. The device will have 3 7-Segment LED Displays to show the instantaneous acceleration measurement to 2 decimal accuracy.

This is a very small telephone exchange system with two ordinary telephones attached. Full bi-directional facility with an intercom system: when a phone is in off hook condition , the circuit will detect it & send ringing pulse to the other phone. When it will be picked up , the connection will be established between both phones. This will take place vice-versa also. This project sounds great if you need a simple and efficient communication system, like in a tree house, you place on telephone in the tree house and the other one in your house. This is just an example but there are far more applications for this system.

This is a great project if you have some spare time, and some spare junk. The boat is built entirely with what you can find around the house like: 2 computer fans, remote controll,servo and battery from a broken RC plane and an old bicycle tire tube. And it actually works, it floats and can be steered around. From the movie we can also notice that the fishes like it 
The idea is so original and cool, a box that closes itself ? c’mon :). There is also a website www.leavemealonebox.com but it is unavailable now when I’m writing the article.
This project’s display is made of a number of tiles, about 2″ square with an 8 x 8 array of color LED pixels. Each tile is individually powered and animated, so your can freely pick them up and re-arrange them. To set up a display, the tiles are placed in a special tray. Animations are downloaded into the tray via Ethernet and stored locally on an EEPROM, or loaded via an SD card. The tray broadcasts the animation to each of the tiles, and then synchronizes them.
If the pieces are left in the tray, the animation can be updated continuously over the Ethernet connection. If the tiles are removed from the tray, they’ll display the animation for several hours with their own re-chargeable battery power. Once the animation is synchronized and running on the tiles, you can pick them up and place them anywhere.
