Here’s a cool steam candle you can make!
How to make a cool rotating steam engine using only a candle and a thin tube. VERY easy to do and fun to watch! Runs for hours! This is my personal favorite for Christmas decoration 🙂
Here’s a cool DIY voice recognition system by computer engineering students at Cornell University. Nice job, keep up the good work!
When we think of programmable speech recognition, we think of calling FedEx customer service call center with automated voice recognition response systems. We also think of PC-based speech recognition Dragon NaturallySpeaking. Now we took that a step further. We are talking about speech recognition in a tiny M

Cool propeller clock you can make!
How this clock works: A motor spins the “propeller”, and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely.
If you want to build this clock, you will need a few things, including: Skill with motors and mechanical things. Prior electronic experience. A dead VCR or floppy drive or other source of a suitable

But I don’t own a Wii console. So I hacked away in linux and got it to control my xmms mp3 player. All buttons except power button work as follows:

Check out this cool etch CNC. Actually we were thinking of making this too, but since it’s already made, we can learn from it and make it quicker. Awesome! 🙂
I am using a retrofit machine that fit within my budget. It’s a 2-axis machine with approximately 170x130mm travel.
The circuit board is my own design, using a ULN2803 per motor to supply approx. 0.3 amps per winding. The power supply is a standard AT hard-drive power connecto
