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
Here’s a Piece of Cake DIY, Mouse pad Couch you can build for yourself if you have lots of extra mouse pads. The thing is, it look really comfortable with all those mouse pads…maybe you can make one out of a memory foam mouse pad.
Here’s a cool upcoming technology that can change the world forever for you if you are blind. It translates text into braille and lots of more features.
The bridge is a neat device. None of the technology is not revolutionary
Check out Bugbots or real bugs with clock embedded in them! Our review is two thumbs up for ingenuity and creativity.
It’s the though that counts right, well if you get your special someone this gift for the holidays I am not sure you will be around to celebrate next years holiday season.

Tool Using Animal shows us how to make a UV flashlight by simply replacing LEDs on a regular flashlight. Well I have a whole bunch of UV LEDs Alan sent me from

Here’s a video of how an electronic drum would work if you made one. This one if cool as it’s a “sponge” drum.
I made a “home made Drum” out of a guitar pickup and a string installed within a piece of sponge. I use Reaktor to translate the signal with its amplitube to snare drums. Each punch, with sound a snare drum (not the same snare all the time, it changes after every puch) and it has a the amplitude of the punch. It is very sensitive and there are some great stuff i can do with the reaktor , like settin

You can now watch races using power tools!
It’s a rocket. Stuck through the back of a skull, sitting on an aging belt sander rigged to a pair of sawed-off skis. And it can haul butt down a track.
Scott David and his 10-year-old son, Cal, built El Diablo del Muerte (“the Devil of Death”) for last summer’s first annual Seattle Power Tool Drag Race and Derby. Inspired by earlier events in

wow… :-]
The ultrasonic sensor and computer software provide a convincing illusion of direct interaction.
“Another installation exercise. Idea copied from another installation for ease. Ultrasonic range finder is used to detect distance of object form it and data is processed in flash, and displayed in form of grass. Same technique can apply to many other skin like running people (from the UFO… )”

Here’s the video for the Bike POV earlier.
Nice “Merry Christmas and Happy New Year”, guys! (or girls)
Nicely done RGB Bike POV! POV stands for Persistence of Vision, check out wikipedia definition if you don’t know it yet.
The whole thing is based on a pic16f628A, with some SMD mosfets to power the led’s. Those are very bright RGB led’s with SMD resistors for smaller PCB size and lower weight. That’s important too when keeping in mind
