At the core of the projector are six 100-W metal halide lamps, shining through six images of a horse, laser-cut out of oak plywood. The series of circular shutters between the lights and the cut-outs are set up so that only one light at a time is unmasked, allowing it to shine through and cast the image on the wall. So as the shutters rotate, the images are cast in sequence.
The rotation of the shutters is powered by a generator mounted onto an adjacent exercise bicycle. And, of course, by getting on the generator bicycle, the viewer casts his shadow onto the image of the horse, so that he becomes the horseback rider. A circuit on the front of the bike smoothes out the power coming out of the generator, limiting the voltage to the machine so the shutters don't spin too quickly, and also sending the proper voltage and current to a cassette player on the front of the bike (it plays music on the headphones when you pedal) and a device that makes the viewer's shadow flicker in sync with the horse.
Jason Koebler and Lorenzo Franceschi-Bicchierai received a $100 iPhone X from China and marveled at how convincing the top-to-bottom, software-to-hardware bootleggery is. iOS is recreated down to the pixel as an Android skin; only the sluggish performance, on-screen keyboard give the game away. Even many of the apps are nearly perfect, though once they run […]

A similar tally is listed at a follow-up Indiegogo page. Unlike […]

A great sign: not only has it received spec bumps to 8GB of RAM and a decent GPU, but owners can install Linux. You probably […]

It’s good to be proactive, but when it comes to preparing for an emergency situation, one of the most important items you can pack is a flashlight. After all, whatever else you include in your kit won’t be of much use if you can’t see what you’re doing. The Viper 1000-Lumen Tactical Flashlights not only […]
Chances are you took a handful of language classes in high school, and aside from a smattering of conjugations and vocabulary words, the only things you likely remember are the dry, rehearsed sentences that did little to make you speak like a true native. If you’re still hoping to learn a new language but want […]
