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

Remote Controlled Camera from a Cellphone

Wow what a hack! SMS your hacked cell phone and it will take a picture and send it back to you! Have a look at the details of this Remote Controlled Camera from a Cellphone that uses a Picaxe microcontroller. I would dare anyone to try to take this onto a plane. I am sure the conversation would include “Honestly it is just a remote camera that looks like a

Mech Robot

Andres Bella has created a cool Mech Robot that is powered by a Parallax Microcontroller. “I used a Basic Stamp II microcontroller, is pretty easy to program, and it does everything I need for this project, I got a Power Started that is a very good power supply and gives me enough juice to power up all the electronics, the motors, and the compressor. The micro-controlled controls the solenoids valve

ShakerRacer BlueTooth RC Cell Phone Car

Andreas Jakl developed the software and Stephan Selinger developed the hardware for the Shaker Racer at Symbian Resources. It reminds me of this RC Car Wiimote hack. Stephan sent in some pictures of the car hardware and some additional details. Thanks Stephan! “We are using an MSP430 microcontroller by Texas instruments on a board by www.olimex.com and the BlueNiceCom IV Bluetooth module. The microcontroller software is written in C.” Video

Video Circuit Bending

In most cases when you hear about circuit bending it refers to bending of the audio signal of various hardware devices. I ran across this web site that deals with the bending of video devices. This web site is packed full of stuff. The author displays sequential images of bending a device and provides video links of bent output. When possible he provides links to manufacture documentation and schematics. In

Battery University

Have you ever wondered about all of the different batteries on the market these days? Urban legends about batteries?? Are you suppose to drain them completely before you charge them or charge them after every use? Would you like to build a smart battery charger to charge the your batteries just enough so you will not fry them? When would you use nickel-cadmium over nickel-metal-hydride? Why would you want to

Smart RFID Poker Table

James Brown, Shawn Ironmonger, Michael Moninski and Dan Moore from Purdue University put together quite the gambling machine. They made a Smart RFID Poker Table that could keep track of where chips where placed on the table. After watching a few of the gambling cheat shows on TV where people use misdirection and slight of hand to increase their bets when it is in their favor would be shot down
