We have all seen the electric shock game . This hack takes an old Reductronic exercise machine and makes it into a shock game. “Reductronic is a old system to exercise the muscles of the human body by the use of electricity , the system was hacked to interfere the nerve system and establish sinestesia with the auditive system. The electrical current circulates through the body at the rhythm
I didn’t think that the lasers in DVD burners were this powerful. If you have one that died (hopefully not because of laser failure) you might want to make your own high power laser. Be very careful when playing with something like this. I would suggest using laser goggles when operating. “The laser pictured above has a peak output measured at 225 mW (average output 200 mW). It’s a
You might remember the article where uC Hobby demonstrated how to power projects using a computer power supply. One of the issues was that there was a possibility of causing permanent damage if something accidentally got shorted out. Dave has fixed that designing a simple current limiting circuit. With the circuit installed you can now short out the power tap and know that worst case is a 200mA draw. Have
The effect of the Invisibility Sphere is interesting, looks like there are still some glitches that have to be worked out. I would love to see this using flat panel monitors with very small seams between them. “Artist attempts to build an invisible sphere. 215 monitors are placed directly opposite 215 cameras, allowing the viewer to peer directly through a eight hundred pound mass of steel, glass and electronics.” Via:
Check out this very cool lighthouse project “This design is for an octagon lamp for simulating a lighthouse 6 second round trip flash. The lighthouse stands about 6 feet tall, an outline of the lamp head is should on the cardboard of one of the pix. I am really liking the Atmel Tiny controllers, very cool and a true RISC design (no funky divide by 4 microchip T state stuff,
Our friend from Denmark is back at it! After David purchased a wireless keyboard that didn’t have the range needed what did he do? Return it for a different model? That would be no fun… He instead cracked open the equipment and installed some monster antenas that were salvaged from a dead WiFi router. “The core of the antenna cable was soldered to the start of the internal antenne which
I think this is a first! I have never seen a POV golf club before. “As you can see, the letters will go backwards on the backswing and forwards on the forwardswing. Ben Hogan’s “Five Lessons†has a good picture of correct swing arc for a golf swing. Actually that is the reason we named it after the great American golfer, Ben Hogan. I am sure Ben Hogan would
