This is a Binary Counter based on 555 timer and 4520 CMOS integrated circuit.The circuit looks simple and easy to build ,but with a simple modification you can turn your circuit into device that works like high tech dice.Rather then throwing dice to create a number you can use your 4520 to create random numbers between 0 and 15.

Miniature fires that flicker create the sense that someone is nearby in a model scene. They can add a moving effect to a dolls’ house, model railroad or Christmas Village scene.This fire will be created using a set of LED’s especially for the purpose of fire from Evans Design. As this fire is going to be part of a portable table display, a 9 volt battery will be used to power the LED’s which in this case are designed for DC (direct current) use.[more]
On this website you will see how to build a meter which measures the lateral acceleration force in car, also called g-force or centrifugal force. This is the force which pushes the driver or passenger to the left in a fast right hand turn. The force is normally expressed in g, 1 g (9.8 m/s/s) corresponds to the acceleration due to gravity.A normal car can handle approximately 0.8 g, above this values, the tires cannot handle the sideways force anymore and the car will move sideways. The best sports cars can handle up to approximately 1 g.[more]
Cool idea place of wearable computing art projects from REACTIVEfashion website.REACTIVEfashion is a cross-disciplinary collaborative project created by Angela Sheehan and Rebecca Grabman at Bennington College. A combination of physical computing and costume design, the REACTIVEfashion line is a series of wearable computing art projects exploring the intersection of technology, clothing, and performance. REACTIVEfashion was featured in the Spring Fashion show, the Senior Art Show, and a DIY Workshop throughout Spring. [more]
This is a cheap DIY credit card reader project.The reader mechanism consists of magnetic head on a spring mechanism along with low level head signal amplifiers and data slicers. Three signal lines comming from the unit provide card presence, clock, and data.The data from the unit read by PIC12F675 in ASCII format then send to PC via RS232.[more]
