[Justin] sent in his Digitally Assisted Billiards project. Using a web cam, a computer and a projector, these guys have set up a system that shows you the trajectories of your current shot. It detects the angle of the cue and displays a glowing blue line showing where each ball would go and where the collisions would be. It is a bit slow right now, and made somewhat less accurate by a low resolution web camera. This could be a fantastic teaching tool if it were to get some more polish. The source code is available on the site, so you could try this one out at home.

22″ Binocular Telescope

binocular

This is the worlds largest known visual binocular. Why binocular and not just a regular telescope? Well, it all has to do with clarity. Apparently when you can use both eyes, you can see much more detail and pick up light better. The author states in one story that he was able to see a spiral galaxy clearly with a binocular telescope, but couldn’t see it at all with a monocular telescope of the same power.

There is information on several models on the site. Look in the right hand column as well for useful links to parts distributors.

Simple Laser Projector

[kap4001] built what has to be the simplest laser scanner possible. It’s two servos strapped together with zip ties plus a 5V laser module. They’re connected to a Pololu serial servo controller. The laser is pulsed by switching the DTR line. You could use it to draw images like the one above… except that’s an 85 second exposure.

You’ve probably seen musical Tesla coils already. People have wired them up to computers and keyboards to make them serve as dangerous and awesome speakers. This video popped up of someone playing his guitar through one. It is rough, and not very good at polyphony, but still cool. We would like to see several coils, split by different filters to be able to hear more of the guitar chords. If only someone had rigged these up for Queen when Flash Gordan was made.

Roboexotica 2008

We couldn’t make Roboexotica in Vienna, Austria this year (check out last year’s coverage), so we asked [Bre Pettis] to act as our liaison.

Last night was the opening party of Roboexotica, the worldwide gathering of cocktail robots. It was a blast! Pictured above is Robovox, a 40 foot high robot that you can text message to and it will say what you text to it! Continue reading “Roboexotica 2008” →

A couple months ago we posted [Ben Heck]’s in-progress photos of his Xbox 360 laptop (with links to his other versions). He’s just put the finishing touches on it, and dubbed it the Xbox 360 Portable. It has a removable hard drive on top and memory slots on the side. The webcam is embedded in the frame and there’s internal WiFi. With chatpads available now, he’s decided not to include a keyboard. It’s really a nice machine. Check out the video below for a tour of the system.

Nintendo 64 Crammed Into A NES

[Matthew] sent us this Nintendo 64 stuffed into an NES. He did a great job really, everything looks nice and tidy. the presentation is decent with only the game ports visible on the front to tell you its not stock. The accent lighting on the side vents is not overpowering. Overall this was a really well done mod. Just like the Nintendo 64 in a Wii mod, this only plays Nintendo 64 games. OK guys, lets get some mods going that don’t involve cramming one Nintendo product into another Nintendo product.
