Digital Capacitors

Afroman’s digital capacitor writeup is mostly theory, but it has some good applications and looks like it could be pretty useful for future projects “By manipulating the input/output states on a microcontroller, you can effectively switch capacitors in and out of circuit, as long as the circuit requires one end of the capacitor to be connected to ground when it is in use. When you set a PIC’s tristate buffer

Interactive LED Table Build

Our friends over at the Deadly Computer Blog have just finished an Interactive LED Table Build. The results are great! “ A few months ago I saw this Interactive LED Table on a bunch of blogs and instantly knew I must have my own. I contacted the people over at Evil Mad Scientist about their kits, and put in my order. That was in October, and I have been slowly

Crazy Wii Case Mod - UV Hack Up

This Wii mod is one of the most extreme mods I have seen for the Nintendo Wii so far. The video goes over the mods that this machine went through. “After a long time of work I have completed my Wii Here is my Worklist: -lightbar led exchange to Ice blue -clear/black case install -internal gecko adapter -internal GC memorycard -black painted Wii drive -black painted metal back plate -leds

Cornell University ECE576 Advanced Microcontroller Final Projects

Bruce Land teaches a great course at Cornell University called Advanced Microcontroller Systems on a Programmable Chip (ECE576). This looks to be the big brother to this course. Bruce was kind enough to drop us a line to share the latest group of ECE576 Final Projects. They are all impressive but here are a few of my favorites. This is the Light Source Motion Tracking project. One thing to remember

RFID Proximity Security System

Here is final project from two Cornell students who researched, designed and implemented an RFID proximity security system. They decided to build a proximity security system as their student id cards supported both magnetic strip and RFID tags. Many of the controlled areas on campus were switching to proximity entry systems. The maximum range of their proximity card reader is about 1.5 to 2.0 inches from the antenna coil. There
