Sean over at LED MOD has some cool LED car mod products. I would be interested to know how the RPM changing kits sense the RPM. Is there a line that goes to the spark plug or is there some sort of data connection to the car computer? However it works the results are great!
The VGA Test Box project allows a normal microcontroller to output directly to a CRT monitor for testing. “The goal of this project is to create a device that is capable of outputting VGA signals to a CRT monitor in order to display figures, text and characters. Timing is a core essential in this project. If the signal is off by even 1 microsecond, the signal synchronization with the CRT
Johnny Lee a Ph.D. student from Carnegie Mellon Univerisity is working on some interesting projects. Looks like these prototype Foldable Displays are quite advanced. I can think of so many applications for these displays. The second video demonstrates an prototype automatic projector calibration system that is fast and accurate. “Using infrared tracking and projection, we can simulate displays on flexible and foldable surfaces. This allows us to fit a
Doktor Andy is back to his crazy designs! When you can’t easily hack out a signal from a controller why not make a circuit that “looks” at it for you. That is exactly what the Ghetto BPM Detection does. 🙂 “This one is inspired by my experiences with the band and the DJ-Set and…well…you know why =-). Anyway, for already quite a long time I am looking for a way
LloydGod has created a bot that senses light and walks away from the shadows. “This is a little project from last winter. I hope to make some better shaped legs one of these days for improved walking. When the light on the 2 photo diodes is balanced the rear legs movement is equal on each side. When 1 photo diode is brighter than the other the rear legs will
The Wii Remote has an infrared camera in the front that is normally watching for the infrared LEDs that are mounted in the sensor bar. This camera is actually quite sensitive and can be used for some cool things! Jcl5m has come up with a method that uses reflected IR light from small reflectors to provide the Minority Report style interaction. Via: Hack a Wii
Carlos demonstrates how to build a simple IR detector. Looks like it could be done for a dollar or two. “An IR signal is “seen” by a reverse biased IR diode which produced an electrical signal according to the light intensity. This signal is then amplified trough a transistor and used to power an ordinary LED. This means that the LED will light up when the IR diodes receives some
