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.
Wow camera technology is getting small! When attaching the wires to the camera is one of the main challenges you know you are dealing with something that is very small. These cameras are build using VSLI production just like chips are made. Awaiba has been working on perfecting this camera for a long time, it is best suited for the medical field but I can think of lots of other
This solar tracking system uses an antenna motor which is normally used to spin an old school roof mounted antenna around. The structure is home made from some satellite dish parts and unistrut as the main frame of the solar panels. I was expecting to see several light sensors and some circuitry to see where the sun was and constantly follow it like we have seen before. But fanman1981 actually
This 3d iPad Demo is future of portable media! Laurence Nigay, a professor from France was inspired by the 3D work done by Johnny Lee who we interviewed a few years ago (blogs here and now works for the Google). “We track the head of the user with the front facing camera in order to create a glasses-free monocular 3D display. Such spatially-aware mobile display enables to improve the possibilities
This is a cool looking Bubble Display Project. Who doesn’t want to play an instrument that is connected to bubble making system! I think there would be a lot more piano players out there if this was hooked up to pianos in schools. 🙂 “The board was built to support up to 64 outputs. Each output had an LED. It was a simple design of several I/O expanders on an
Remember those magic 8 balls that would help you make decisions? Well Pete Mills decided to make one but of course it isn’t filled with fluid this Magic 8 Ball is filled with electronic goodness. It is controlled by a ATMega328 and if you want to make your own Pete has posted the code here. “You can see the mercury switch in the picture below. It is hot glued to
Now that spring has arrived you might be looking for something new to build that can be used outside. Why not make something that can be used to protect your property in a non-lethal way? We have see lots of sentry guns over the years but quite a few of them has closed source code. This Sentry Gun Project has code that has been released which is sure to help
