Time-Saving Exercise Bike for Computer Users
Replace Belly with a Six Pack without a Time Investment
Lots of people today spend large amount of time in front a computer without moving. That's bad for their bodies. But now, with Twibright Exciter, Internet surfing can have similar effect on your fat level and aerobic fitness as wave surfing. Exciter is an exercise bike designed to be ridden when using a computer. It can be connected to power a laptop, LCD monitor or a desk lamp and this way the user has a great motivation to continue the exercise.
Have Fun riding an Induction Generator with Your PC
We designed Exciter with SEIG, Self Excited Induction Generator. Ordinary 3-phase squirrel cage asynchronous motor and some capacitors create a difficult to understand generator circuit. When Exciter is pedaled above critical speed, positive electromagnetic feedback is established and powerful voltage oscillation appears. This manifests as three-phase sine wave on the motor output. This is rectified with 6 diodes so that all three windings can work together into a single load. Exciter then produces up to 120 watts of line voltage DC power, which can be used to power computer or laptop power supply, switch mode AC/DC adapters, fluorescent or incandescent light bulb.
Wow, just what I need. I just happen to have a broken bike (I garaged it while on my roof rack) and I could take this build this for this winter. I could generate enough power to run the Powerbook and get into riding shape at the same time!
I'd rather ride in the winter than now -- criminey, it must be 60% humidity with 73 degrees at 7:30 in the morning. Gonna prove to be a sticky, icky day, with a high above 90. And I gotta work at the liquor store tonight too. I rode slowly as to not work myself up too much, but that didn't work. In this weather you're going to sweat.
Bleah. This is my least favorite time of year. I'm not really heat tolerant and I hate humidity. Normally, I'm just a cool, collected guy, but weather like this just makes me that fat, sweaty guy I really am. Bleah.
