World Weather Umbrella


[Peter] brings us the oddest hack of the week. It’s a little esoteric, but interesting. This modified umbrella is used in conjunction with a giant world map outline. A camera takes note of the umbrella position and correlates the location. The user walks around and ‘experiences’ the weather in that location of the world. If you’d prefer to have everyone think you’re nuts, you could just interface it with your ipod.

Balancing One Wheel Scooter


Fresh off the tip line, [Ben] sent in his one wheeled balancing scooter. It’s a nice simple design – I just might have to build one myself. The steel frame surrounds a pair of 12V 12Ah SLA batteries, a 400w 24v DC motor, one of the ever handy OSMC motor controllers, rate gyro, accelerometer and a PIC 16F876A. I love the entire concept! (For some reason, I’m thinking it needs a brake light on the rear…

Check out the video after the cut. He walks through the hardware at the end.

By the way, Eliot and I’ll be at Shmoocon in a couple of weeks. We won’t have boards from the Design Challenge yet, but we should have something to give away to people who find us there.

DIY ‘midi’ Footpedal


[forrest] passed along this diy foot-pedal ‘midi’ controller. It’s a good re-use of hardware, but not a true midi controller. The pcb was gutted from an old keyboard, and the pedals were scored from a mad 60 mile tour of the local radio shacks clearance bin. Since the pedals are simple momentary on switches, it was a matter of wiring them to the controller and using a laptop to generate signals via usb midi interface. Replace the keyboard pcb with a drum controller and you’d have an interesting stand alone solution.

Just so I could enjoy some extra crow, I managed to leave one other entry out of my published list of Design Challenge entries. [Jason] sent in this MEGA32 programmer/dev board. He kept it single sided, but you’ll need a parallel port to use it.

AVR Game Console


This is a bit reminiscent of the missing DC entry, so consider it a bonus hack. [Eric] sent in his latest project, an AVR game console. It uses a pair of ATMega168v micro-controllers, a nokia 3110 LCD, and an eeprom to store a selection of games. The interface above the console is the serial loader/charger. No word on the game source, but judging from his site, maybe he’s writing them all on his own.
