Interesting idea. I might give this a try with a set of old speakers I have laying around. I think I would use a more powerful laser though so that it is a bit brighter. “Bryan was telling us over dinner how in school his science teacher setup a laser light show. Bryan has a laser level, so we decided to do it. The concept is so simple. Basically, the
The aims of the project were to: a) Reduce the noise level b) See if I could do it I was not looking to lower the temperature to improve the stability. Ive heard reports in forums of the 360 overheating but I have not noticed this myself. read more | digg story
Thomas Grocutt has built a PC based oscilloscope. He has full plans and build information on his site so you can build your own! “The initial purpose of this project was to create a cheap, easy to use digital storage oscilloscope (DSO). However we have gone a bit further since the original idea. One of the biggest problems with most DSO’s is there small storage depth, we decided to solve
Steve Kosmerchock built a small light weight rocket timer for a friend of his. He is selling them for $40 on the XAVIEN web site. If you want to build your own Steve provides the schematic and firmware for free on his site. Have a look at some of his other PIC projects. Steve explains how the project started, “A co-worker of mine wanted a small timer that ranged from
Check out David Worden’s computer controlled Disco Bar with 128 LEDs! He used control boards from Dropout Design. “Yes, I would sell my bar. A minimum of $5,000. Yes, its a rediculously high price that no one would ever pay, but it would have to be worthwhile for me to sell it with all the work I put into it. The bar is very safe actually. I have epoxy pretty
Mondo Technology has hacked a Furby in a different way. They scrapped all of the existing controllers and started from scratch. “The mechanism of the Furby itself was designed around micro- controllers. It has one motor that runs the eyes, mouth, and ears in sequence. Two sensors are provided from the motor servo system: one counts off about 200 pulses for the entire sequence, the other is an ‘index’ pulse
David Barrett has taken TTL logic to the extreme! No his logic isn’t controlling a photocopier, printer or some obscure computer equipment. David’s TTL handywork is controlling a 180 Amp TIG Welder. “Many modern welder front panel’s were looked at and many dozens of spec sheets studied to gain a list of requirements, then it was simply a case of reproducing those function’s simply and cheaply. The descision was made
