Ray Ho and Ayo Ositelu from Cornell University came up with an inexpensive (around $25) way to do eye tracking. They’re using an IR LED and an IR transistor to get the job done. They note that the best way to perform eye tracking is to use a camera and process the image but this would require more processing power than they had. We have seen eye tracking done
It’s just a matter of time before you spill some liquid into your computer keyboard or it naturally gets full of dust and dirt. When this happens keys can stick or may become intermittent. Keyboards are priced to be disposable but that doesn’t mean you should just toss it and buy a new one. Chances are you can take it apart and clean it out. The process should take about
Have a look at the Dune Bug E project. Looks like the warm weather kicked the build into high gear! You know you are dealing with some serious power when you need to cut your cables with bolt cutters and solder on lugs with a blow torch. 🙂 “At this point the Dune Bug-E is up & running, and has had 8 or 9 test drivers without any issues ie;
The new batch of Cornell University ECE 4760 Final Project are in! There are tons of cool projects as usual, everything from Human Tetris to this MIDI Glove Controller project by Anson Dorsey, Eric Gunther and Jonathon Smythe. The project is based around an Atmel Mega644 microcontroller which has lots of processing capability and all of the projects are developed in WINAVR/GCC. Since the system is outputting MIDI you are
DIY medical equipment is not a big hobby area but this DIY Pulse Oximeter is one cool device. I have no idea what a commercial Pulse Oximeter but like anything medical the real stuff that is used in hospitals usually costs big bucks. In this case your finger is slipped between two pieces of medical grade oak to take the reading. The project is based around the powerful 68HC908AB32 microcontroller.
If you are looking for a new piece of test gear to help you with your next design have a look at what Matt from Openschemes has come up with. He has taken a Top2005 EPROM Programmer and hacked into a Desktop Test Bench! “Do you ever find yourself wanting an IC tester? Some way to power up an IC and apply various voltages and signals to different pins, in
This cool PIC Microcontroller based IR to Remote Control Project allows you to program codes from a standard remote control to control this small module. When setup you will be able to control two items from across the room. If you attempt this project make sure you are careful since line voltage is involved. Thanks Muris. “Features of current beta version of firmware: – Controlling two independent appliances via remote
