Most of us have a bunch of these old mice laying around collecting dust. If you didn’t make some cool art with your mice last week here is another idea to recycle it into a cool project. This article will show you how to turn an ordinary mouse into a flashlight, perfect for looking into computer cases that always seem to be in the darkest corner of the room. You
Check out the cool coil gun projects at Another Coilgun Site. Near the end of the video you will see the coil hand gun! This thing is computer controlled using a microcontroller for enhanced operation. “At last!! A functioning example of the combined wants in a coilgun pistol. You always see posts for this and that, read how if it could do such and such and the inevitable plans on
Here is a nice simple LED light chaser from the Hacked Gadgets Forum. There is a full schematic provided, I am not sure if the author will be providing the chip code however. “4 functions triggered by the length of time control button is pressed. 1. Tap once to change patterns. 2. Press and hold for 0.5 seconds until 2 Leds start flashing then release. Unit will power off. 3.
Here is a cool mod to add a USB port to your alarm clock. “To add our USB power port, we’ll steal some DC voltage from the clock. We are going to run power through a LM 7805 voltage regulator to take it down to 5 volts. Adding a 220uF capacitor between the output and the ground can help smooth out the voltage if that’s a concern. We referenced the
If you are looking to make a DIY PIC chip Frequency Counter check out this site. There is full instructions on how to make your own. “The circuit diagram is so simple that I didn’t make a complete Eagle schematic for it yet (other builders did, see links). The first prototype was built on a breadboard with round pads. A very similar design could be used for a single-sided printed
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
