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
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
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
Eric (Turd) from the Hacked Gadgets Forum has shared a project that he has been working on. He has made a FreeBasic program that interfaced to a custom circuit board that he designed and built. This will allow a computer to control an LCD display. This gives you lots of possibilities such as having a temperature monitor or CPU usage display for easy viewing. All the code and schematics
This is a proof of concept project that contains lots of great code and helpful tips that could help us out when we are working on a similar Ethernet / microcontroller project. Project abstract (pdf) Entire Project Details (zip) The “Ethernet Picture Viewer” is a low cost device that allows a user to visualize graphic content stored on a computer in an LAN. A server application that runs on
The Revision 3 show Systm has been on and off since it was introduced many years ago. It looks like it’s now here to stay so we can expect to see videos on a regular basis. Patrick Norton will be joined by David Calkins which should make the shows very interesting and informative. This episode talks about installing a RFID lock in your bar fridge, the locking mechanism is
This DIY Push Pull Tube Amp Build doesn’t need a circuit board since everything is done using point to point wiring. If you open up some old equipment such a TV or stereo you will see that this type of wiring was the norm. It is hard to believe that this was the way mass produced equipment was constructed. "Initially I started with 6EU7 tubes in the preamp stage
