1. 32 RGB LED Magic Ball With a bunch of RGB (Red Green Blue) LEDs you can make a real cool display. This one was made using a Microchip 16F628 microcontroller and serial to parallel converter chips since the 16F628 doesn’t have 32 outputs. 2. SPIN Talk about life size. The SPIN display is massive and has a nice effect. “We’ve all seen a train or a car whizzing past
If you need to do some temperature measurement, this project will allow you to interface an inexpensive yet accurate sensor to your computer. “This small circuit can measure and on the Bildschirm/in of a log file spend/store a temperature exact up to 0.5 C° with a DS1820 Temeratursensor. That e.g. is. practically in order over Internet/Lan temperatures in areas to supervise (server area) or around the outside temperature on an
I hate running out of USB ports. Some manufactures think they know best and stick a bunch of ports in the back of systems and none in the front. Well with this hack your USB problems will be over for good. Via: Make
This bike mounted POV is unique, there have been quite a few floating around recently but I have never seen one that calculated and displayed the RPM of the device. Based on wheel diameter the current speed would also be easy to calculate and display. Original article (link within text is converted to English) Here are some links to some other Bike POVs: Link 1, Link 2, Link 3, Link
This clock hack is a neat idea. Passing light through the LCD allows the clock image to be projected on a wall. To make the project a bit cooler it activates with a remote control. The inspiration was the watch projection clock project. ” This is a clock that projects the time onto the wall of a darkened room whenever any IR remote control (like a TV remote) is pointed
If you have an old microwave that is not being used why not use it to melt metal. “Research is nearing completion on a system that will allow the melting and casting of bronze, silver, gold, and even cast iron, using an unmodified domestic microwave oven as the energy source. To be of use for metal casting, a domestic microwave oven rated D or E (850W or 1000W) needs two
Sylvain Ferrand from France has made a Web server that you could build and stuff in your pocket. No hard drive, monitor, CD-Rom drive etc. Just a handful of components and some code. Take a look at his site for the schematic and components you need. “The ENC28J60 is a single chip 10mb Ethernet controller easy to drive by a microcontroller with SPI bus. It’s a cheap low pin-out (28
