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
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
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
MechRC is a cool new robot that is very technical but unlike other applications of technology where the product becomes more complex this device is simplified by it. Unlike most programming where you need to enter complex commands to be executed with this robot you simply show it what you would like! Our friends over at Trossen Robotics are the first in the United States to offer the robot,
You may remember the Grad Cap LED Hack that we had here last year, this Grad Gown LED hack uses a bunch of LEDs that are connected to an audio detection circuit that makes it into a VU meter! It is one of the entries in the Curious Inventor Contest, this is the last day of the contest so hurry to get an entry in. "I had an idea
