Wiimote Hacked to Analize Tennis Serves

  If you are looking for a compact, rugged, and cheap sensor filled package there is nothing better than a Wiimote. This Wiimote was Hacked to Analize Tennis Serves. It’s great that there is an abundance of creative people working to make interfacing to devices like the Wiimote a bit simpler than it could be if everyone was starting from scratch. Via: Hack a Wii "So if you are a

Spinning LED Display using Fan Motor

  Csaba Bleuer has completed version 2 of his spinning LED display. Here is what version 1 of the spinning LED display looked like. "Improvements are: The rotation speed is 25/s instead of 7/s like in the earlier version, thanks to a cooling fan motor, which can give about 10W power and enough torque at 1800rpm. Also the power supplying is changed for the rotating part. It gets negative through

Automatic Cat Food Dispenser

  This is a very cool Automatic Cat Food Dispenser project. Who wouldn’t want to feed their cats automatically. The project could have stopped at about 10 percent of where it is at and still accomplished the goal of automatic feeding but that would be no fun. If the project is worth doing it is worth over doing, and this is exactly what happened here. Andres Leon built this automatic

Loo Log - Washroom Usage Monitoring

  If you live in a house that has more people than washrooms you have probably come across the situation where you are waiting for one to free up. Sven has come up with a solution, use a microcontroller to capture usage information and graph it so that you can see what the typical usage patten is like! Have a look at the recent graphs for some additional details. 🙂

Coffee making Robot

  I need one of these robots to make me some coffee in the morning! Even though I a sure there was lots of prep prior to each mini scene this robot is actually very strong and flexible! Thanks for sending it in Alex.

ioBridge and Arduino Internet Message Center

  With a few buttons, an LCD screen, an Arduino and a ioBridge, this project allows you to gather information locally and from the internet for instant display. In this example a local temperature sensor displays the local temperature while a internet based service used to get the temperature from another location. An online financial site is used to gather stock prices so that when you are in the kitchen

Nevada Lightning Laboratory Experiments

  The Nevada Lightning Laboratory were recently trying many experiments, such as what would happen if you flew a small radio controlled helicopter between two Tesla coils, could a small vehicle big enough for one person be powered using a Tesla coil. Watch the videos below for the cool answers. "We’ve done a number of things using Tesla’s original schematic, and have been able to transmit and receive considerable amounts
