Ashish Derhgawen has done lots of interesting work with vision. You can see all of his projects on his Ashish’s Programming Journal. Best of all the vision is captured with a simple webcam which makes these projects possible for any hobbyist. Here are a few links to my favorite projects of his. Laser Pointer used as a Mouse (first video). Pan Tilt Webcam using a Mouse (second video). This
Carl Erickson from Phenostream has built a very small yet very smart stepper motor. Many of them can be controlled via a daisy chained serial connection which could make it simple to interface with complex projects. This car project is a cool example of the possibilities. "The OpenStepper Module (OSM) is comprised of a GSM_01 and the OpenStepper circuit board. OSM firmware is based on Mike Thompson’s popular OpenServo
Here is an interesting talk with Mitch Altman who is the creator of the TV B Gone. It is nice to see that he is genuinely interested in sharing his electronic passion with others.
I just bought a pair of Sennheiser headphones that isolate the outside sound so that the music you hear is crystal clear, the drivers are also very far into your ear. This produces a music (or podcast) experience that is fantastic. One other side benifet is that the volume is very low. Using the stock portable music player headphones I would have to crank the volume to get an
A Gyroscope, Accelerometer and Magnetometer are used to allow a small electronic device that is worn in a boot to keep track of your movements and therefore your actual location.
If you get a sore back from bad posture habits or repetitive stress situations from work this Strain Sensors technology could help you in the near future. The sensors remind me of the glove keyboard sensors we have seen before. If this technology advances as fast as everything else is we will soon have these microscopic sensors woven directly into the fabric of a shirt and the outputs will
This AVR Microcontroller Based Video Game board is very well made for a prototype board! It goes to show that with the power of a modern day microcontroller you can do what used to take many huge boards full of electronics not that long ago. "When I started with the AVRs, i was wondering if it would be possible to create a fluid game like Super Mario Bros, based
