Now make it life size

Here’s a scale model of the classic Playstation game Wipeout. It uses quantum levitation, superconductors, liquid nitrogen, and incredibly detailed models of the cars in Wipeout. They’re able control the speed and direction of the cars electronically. Somebody get on making one of these I can drive. Never mind, it’s totally fake, but here’s a choo-choo that does the same thing. Thanks for the link, [Ben].

Found a use for eight copies of Deep Impact

Where do you keep all your wire? [Paul] keeps his inside VHS tapes. It’s one of the most efficient ways of storing wire we’ve seen, just don’t touch those VHS copies of the original Star Wars trilogy.

There’s MAME machines for pinball?

MAME arcade machines are old hat, but we’ve never seen something to emulate pinball. The build uses two LCD monitors, a small computer and PinMAME. There’s videos in the build log; tell us if we’re stupid for wanting to build one. Thanks go to [Adrian] for sending this one in.

LEGO binary to decimal conversion

[Carl] is doing a few experiments to see if it’s possible to build a calculating machine out of LEGO. He managed to convert four bits of binary into decimal. We’ve seen a LEGO Antikythera mechanism but nothing on the order of an Analytical Engine or some Diamond Age rod logic. Keep it up, [Carl].

Lubs and Dubs that aren’t for dubstep

The folks at Toymaker Television posted a neat demo of heart rhythms emulated with a microprocessor. It cycles through normal sinus rhythm, atrial fibrillation, atrial flutter, and everything else that can go wrong with your heart. We know some nurses that would have loved this in school.

Using videotape tape as a controller

Behold the Bodystick, an instrument built and demonstrated by [Erich Lesovsky]. It’s a bit like a string bass but instead of strings there is a strip of VHS tape. Apparently not all VHS tape will work, but if you have the right kind you can run voltage through it and then change the resistance with a touch of your finger. It seems that the hand not touching the tape needs to be touching a conductive pad, completing the circuit. The resulting resistance changes the oscillator values on a CD40106 CMOS chip. This project is a bit out there (just like [Erich's] Mega-Tape-O-Phone), and in keeping with its peculiarity is the demo video after the break. Enjoy!

VHS toaster

vhs-toaster

Though the inspiration was said to have come from a clip of The Young Ones, we all know this was bound to happen eventually. [lemonie] has turned a VHS deck into a toaster. They’ve done a fantastic job, it looks almost perfectly stock. We can imagine that maintaining the look of the VCR was pretty difficult especially getting everything to line up correctly. Finally, we have a use for our old VHS deck. You can see a video of it in action after the break.
