So yeah, as a PR stunt Volvo let an actual Hamster drive a truck. See for yourself, not bad. There was a guy helping the little critter, but nonetheless the ad was for smooth steering. And if a tiny hamster is enough to turn the steering wheel I’d have to agree, that is smooth steering.
Yeah, the gears move, naturally. That isn’t even the best part, the gears form a sort of mechanical calculator, as the gears are embossed with the number of teeth on each, so you can work out ratios and such. Not a particularly useful calculator, but most certainly a cool iPhone case.
This is a question that the artist Nickolay Lamm wanted to answer. With the help of Astrobiologist M. Browning Vogel, he launched a number of images representing just what wi-fi would look like if it turns out to be visible to the human eye. Of course these are only virtualisations based on wifi signals, so 2.4ghz and 5ghz, If you could actually see radio waves with your eyes the result would be somewhat different.
Thats right, this homemade 3D printer is made of Lego, and you could make one as well! The NXT controls the LEGObot’s power elements: a hot glue gun, a fan and an old VHS camera motor, which powers the printer’s extruder and build platform. So it actually uses melted glue as the material of choice. Besides that It is only made of Lego Parts, and while no match for a MakerBot or similar commercial 3D Printer, It certainly is cool!
