I can’t wait to see some video of this electric bike conversion in action. TheWorkshop.ca has taken an old Suzuki dirt bike and hacked in a powerful electric motor. This isn’t a simple rip and bolt project that we have seen others perform, there was lots of machining and fabrication needed to get it to this stage. An open source motor controller was used which earns it a big
Looks like there is another gas to play around with, we have seen that breathing helium and sulfur hexafluoride has some crazy vocal effects. But now we have an example of breathing xenon gas to change your voice! This was done by the guys over at the Benwl’s Channel who look to be having way too much fun. 🙂 "Xenon’s anesthetic effect is 1.5 times more potent than N2O.
If my fire alarm bell alarm clock clashes with your industrial decor have a look at this Indestructible Binary Alarm Clock. This clock will force you to get up and walk out the door before it shuts off! "When I was laying awake again I started thinking about building the ultimate alarm clock. After some tinkering I decided that it should have these features: It should use an actual
We have featured DIY Induction Heaters here before. There is something about heating a big chunk of metal with no contact that is so appealing. Uzzors2k has a great write-up about his experiments with his Induction Heater, it is filled with trial and error which we can all learn from. "To test my new driver I had a large work coil and tank capacitor already built for a previous
Using a hall effect device a magnet is allowed to hover in mid air. A microcontroller monitors the hall effect feedback to determine how close the magnet is and adjusts the strength of the electromagnet to attract the magnet or allow it to drop. This calculation and adjustment is performed so quickly that the magnet appears to remain at a constant height. Project Page Thanks for the tip Chris.
Greg Pyes has done a great job of hiding a huge Subwoofer in a Floor Cavity. He took pictures along the way so that you too can have your thumping bass and no big speakers in sight.
David from Volunteer Lab Rats is playing with his new ADXL202 Accelerometer. He documented the results so that we can be a few steps closer to getting it to work when we rig one up. "The board is supplied with +5v and ground. There are two output pins on the board. They each output the square shaped signal seen on the picture below. The duty cycle of the signal
