Exploding Watermelons
This is just a fun video of some exploding watermelons, the fun starts at around the 50 second mark. Check out more electrifying elexperiments on his Youtube channel. Via: Make
What Were They Thinking
Wooden Gear Kinetic Sculpture
Brett Dickins has uploaded a new video on the Mechanical Kinetic Art channel. We have featured some their moving sculptured before, this video features a number of sculptures, the first is 9 wooden gears that rotate around themselves. There is a motor driving the sculpture which looks like it must be connected to the center gear. I am assuming that the 8 outer gears are connected with a square frame
Scuba Diving Chair
I thought I had seen it all. If you want to do some scuba diving this is not the way to go about it… Some ideas don’t need to be invented. It looks like the user is tethered to a boat on the surface and probably just hangs on for the ride. It would have been so much better if it was at least an underwater motorcycle.
High Voltage Bat Hook Power Tap – Remote Auxiliary Power System
Dave Coates from the Air Force Research Lab in Dayton Ohio designed this Remote Auxiliary Power System. I don’t know where to begin with this device! I think this device is flawed in so many ways, I hate to think of how much money was pumped into getting this device to this stage… The cable that is being shown in the demonstration is one that would deliver power to a
DIY Sidecar Superbike
François Knorreck works as a technician in a hospital in France, but when he isn’t working he tinkers with motorcycles. He spent 10,000 hours over 10 years and spent 15000 Euros on this DIY Sidecar Superbike. After all is said and done the bike looks a bit different than it did when the build began! François has documented some of the build details here. “While this is a very special
Geek Group Impulse Generator Demonstration – Project Thumper
The Geek Group has lots of interesting equipment but the Thumper Project is one of the most impressive. The system has gone through 7 revisions so far and more are in the works. Our friend Bob Davis has been making lots of similar devices but on a bit of a smaller scale. “Thumper is a High Energy DC Impulse Generator that is capable of producing a 1,800 Volt discharge of
Flash Destroyer – Testing an EEPROM device to Death
Designing a circuit requires reading lots of data sheets. The data sheets contain lots of parameters, for Flash memory one of those values is the number of times the device can be read and written to. In the case of a Microchip 24AA01-I/P 128byte I2C EEPROM the rated number off write cycles is 1 million. Our friend Ian Lesnet from Dangerous Prototypes has designed a device he calls the Flash
