With a few LEDs and some creativity you can put together some very impressive effects. The guys over at Freddiew’s Blog have put together a great video and a how to so that you can make your own LED Light Painting video. Via: Laughing Squid “It’s easy! Here’s what you need: A camera that can do long exposures, or has a “bulb†mode. You can do this with a camera
Congrats to the guys at YourITronics, their BlueRover robot won 1st place in the Digilent Design Contest. `The idea of a remote controlled rover excites almost every electronics student and when we heard about the Digilent contest we realized that we have the possibility to make such a project real. We decided to build our own remote controlled rover but it had to be different from what we’ve seen before. We came up with
Thanks to Dangerous Prototypes for sponsoring the contest this week. They will be providing a project that most of you have already seen! You will be able to test your own storage to death with your very own Flash Destroyer. The current count is just shy of 10 million which is my failure guess. If it doesn’t go soon who knows when it will fail. If you can’t wait you
The Geek Group has lots of interesting equipment but the Thumper Project is one of the most impressive. The system has gone through 7 revisions so far and more are in the works. Our friend Bob Davis has been making lots of similar devices but on a bit of a smaller scale. “Thumper is a High Energy DC Impulse Generator that is capable of producing a 1,800 Volt discharge of
Vassilis Papanikolaou has made a nice Motorcycle Universal Gear Indicator Circuit which allows you to easily see what gear you are in. I am now curious how my first motorcycle indicated the current gear, there was a single 7 segment display between the speedometer and tachometer. I am guessing that it was probably all mechanical but who knows, it might have been this complex! Thanks sending it in Vassilis. “The
This robot by Oddbot is a great example of what can be done with IR light. `The eye consist of 4 IR LEDs and 4 pairs of photo transistors. The phototransistor pairs are connected in parallel to increase their sensitivity. The phototransistor pairs are then connected to your analog inputs the same way you would connect an LDR. This circuit is really 4 FritsLDRs but using phototransistors instead of LDRs.
There was a thread over at DIY Audio that got Toon Beerten thinking about putting together a new amp. I have heard about all these strange amp classes but I haven’t been following them for many years. This Class D amp is actually a class T amp but because of some trademark issues it is branded as a class D. “I considered to construct the AMP6 kit from 41Hz Audio
