In what can either be described as a fun way to make random decisions, or a case of solid over-engineering - comes the latest Instructable by Randy Sarafan. In this example he's designed and built a huge "prize wheel" which is used to determine what the people in the office will have for lunch.
Instead of manually spinning the wheel, it's programmed to automatically spin up at 1145h, and uses a large electric motor with a clutch that's disengaged to allow a natural spin to the point of stopping at a decision.
This could also be used for various games, raffles, perhaps an office chore-wheel and more. Plus the design files have been included so you can order the parts to be laser-cut for neatness. So visit the project Instructable to get started. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
