Bikexi generator

The exhibit uses electromechanical interactive devices to recreate the hand cranked DC power generation invented by Bixi to visitors.

Interaction type: Electromechanical, hands-on. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The exhibit mainly consists of booths and DC generator models. There is a coil fixed above, and the magnet below can be controlled to rotate through a handwheel. The light strip will display different states according to the strength of the power generation. When participating, visitors rotates the magnet through the handwheel, which produces a changing magnetic field. Close the coil to process the changing magnetic field and generate induced electromotive force to light the bulb. The faster visitors rotates, the more lights are illuminated.
