Stealing Joules From An Aluminium-Air Battery

While batteries are cheap and readily obtainable today, sometimes it’s still fun to mess around with their less-common manifestations. Experimenting with a few configurations, Hackaday.io user [will.stevens] has assembled an aluminium-air battery and combined it with a joule thief to light an LED.

To build the air battery, soak an activated charcoal puck — from a water filter, for example — in salt-saturated water while you cut the base off an aluminium can. A circle of tissue paper — also saturated with the salt water — is pressed between the bare charcoal disk and the can, taking care not to …read more

Light Rider: A Lightweight 3D Printed Electric Motorcycle!

It sounds like the name of a vehicle in some sci-fi tale, but that fiction is only a short leap from reality. Light Rider is, in fact, an electric motorcycle with a 3D printed frame that resembles an organic structure more than a machine.

Designed by the Airbus subsidiary [APWorks], the largely hollow frame was devised to minimize weight while maintaining its integrity and facilitating the integration of cables within the structure. The frame is printed by melting a sea aluminium alloy particles together into thousands of layers 30 microns thick. Overall, Light Rider’s frame weighs 30% less than similar …read more
