Here’s a real cool doodle dome using a PICAXE and a 5.25″ floppy drive!
The Doodle Dome was a toy made by Tyco in the early 1990’s. It is basically an Etch-A-Sketch type deal, except that instead of a flat rectangle, it is (most of) a sphere. Like an Etch-a-Sketch, there are two knobs that move a little pointer
Cool, now you can use some regular PC camera to scan 3D objects!
DAVID is a freeware software for laser range scanning. All you need is a PC, a camera (e.g. a webcam), a background corner, and a laser which projects a line onto the object you want to scan. So everyone can use it to scan objects without high costs; this is the big advantage over commercial solutions which are rather expensive.
DAVID has been developed by the computer scientists Dr. Simon W
Here’s a nice vector art CNC tutorial on robotic hand design by Ben!
For today’s How-To we’re going to go through the process of designing a somewhat complex item that can be cut with a standard 3 axis homebuilt CNC machine: a jointed “robotic hand”. This requires several design methods drawn in multiple vi

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)
I don’t know what it is lately, MACs have been very appealing to me lately. Maybe because the new MACs are unix based or what… Regardless of how much money I don’t have in my pocket to buy one, here’s a way you can make your PC look like a MAC and fool people if you have Linux installed…
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

I picked up couple broken monitors at the garbage can nearby where I work last week. (Yes, I am such a el cheapo, I have to go to the dumpster for some hackable parts. Regardless, I also found some PCI serial cards which I needed badly for FREE!) Well, I am planning on some visualizing device…and this VGA expropriator might help me…
