Finally, here’s how the site should ideally look on your computer screen. If you discover broken links or features that don’t work in your web browser, please do let me know [...]

AVR microcontroller based electronic dice

A dice is essentially just a special display for numbers from 1 to 6. Why is a real dice a random number generator? If your hand would have perfect precision mechanics and you could control speed and position exactly then a real dice would probably be deterministic. In other words the one tossing the dice [...]

Short Range Personal Radar

The system will only be required to measure close proximity at an angle of 90 degrees as seen in the example above. The range of system is roughly 4-30cm, 20-150cm & 1m-5.5m depending upon which sensor you choose to use. The outcome of this project will shape future projects where we try to integrate such [...]
