Ashish Derhgawen has built a Computer Controlled Wireless Robot. It uses some linked together off the shelf electronics to get the job done. The vehicle that is being controlled is a Microbric Viper which is normally controlled via IR light. “I’m using a 1/4 wave monopole antenna (6.8 inches) with the RF modules. It’s just a single core wire. The range I get is amazing. I think I get about
This Geiger Counter USB Hack takes an inexpensive Geiger Counter and makes it able to output counts our via USB. This would be very helpful when you want to take readings logged over time. It uses a small microcontroller to interface to the computer. Check out the small circuit implementation above! “The Kvarts DRSB-01 (Кварц ДРСБ-01) is a simple consumer Geiger counter. It does not feature a display of any
Touch sensors are getting more and more popular these days especially since many low cost microcontroller have them built in. If you have a controller that doesn’t have built in touch sensors there are many chips that do just that. The Freescale MPR121 is one of these chips. This MPR121 Touch Sensor Controller Project will give you the pointers you need to get your feet wet with touch sensors. “This
I hope building a Geiger Counter Project is just fun and not a necessity but if you are feeling curious here is a cool DIY Geiger Counter project kit. Via: Dangerous Prototypes “The Geiger Kit is a board that provides the electronics needed to run, and detect events from the GM tube, along with a microprocessor (ATmega328) that makes it easy to customize a solution for processing and outputting the events. Both the Geiger
The spring 2011 batch of Cornell University ECE 4760 Designing with Microcontrollers Final Projects are out. Be prepared to spend a few hours browsing through the details of these cool projects. There is everything from a human tracking fan system to a DJ Touchscreen Device. If you are into playing rock paper scissors have a look at the ECE 4760 project below. David Dunn and Chris Fairfax designed and built
If you had an Atari computer years ago you might remember the 810 floppy drive. Rossum decided to have some fun and make a 8 GB version which is just a bit smaller than the original. The heart of the hack is a microSDdrive with a microcontroller which handles the interface. Via: Make, HackaDay “The hardware is pretty simple: a LPC1114 microcontroller, a microSD slot, a 3v3 regulator, a led
There are some projects that just take your breath away, this 555 Decimal Adding Machine by Alan Yates is definitely one of those. Via: EMSL “The quiescent device pulls 450 mA from its 9 volt supply. Yep, 4 watts! You can feel the warmth coming from the back of it. I could not find ICM7555s in quantity, so was forced to use LM555CNs, making it a rather power hungry device.
