The Personal Mobility Robot (PMR) has a chair for a passenger and balances on two wheels like a Segway. Now the clever folks at the University of Tokyo have added Wii remote control to the platform in a full-sized version of the Segwii. We understand that adding Wiimote control to anything isn’t exactly groundbreaking at this point. That being said, if using stock hardware can increase the quality of the user interface on something like a wheelchair, while decreasing the production cost at the same time, we’re all for it.
[Matlo] worked out a way to use a PS/2 Keyboard and USB mouse with a PlayStation3. The hard work is handled by a Teensy board, which is becoming a popular choice with controller hacks. It interfaces with the keyboard and mouse, translates their input, and sends joystick button commands to the PS3. He is limited to mapping the inputs from a PS3 controller but that is still enough options to work beautifully with first person shooters, especially if you’re used to gaming on a PC instead of a console. If you want to give this one a try, head over to the google code page to download the source code.
[W1VLF] is on a quest to communicate over long distances with a 9 kilohertz transmitter. He built this giant coil with that in mind. A round concrete form was used as a base and wound with magnet wire by hand. We’d recommend building an automated winding device, but this method seems to have worked. Operating at 50 Watts on the air-core coil at 8.97 KHz he was able to pick up the signal at a distance of 5 kilometers. It’s not breaking any overall distance or portability records, but on a project like this the quest is where the fun is at.
