PICBASIC complex LED matrix

This PICBASIC complex LED matrix solution was developed by [Olivier de Broqueville] to drive a matrix of LEDs. Using some cheap transistors, common red LEDs, and a PIC16F628, he is able to drive a 6×6 LED matrix. This project is very well documented and has everything available including: circuit board layouts, schematics, PICBASIC source, VB computer interface program, and parts list.

NES controller connectors for sale

If you weren’t looking forward to trying to find a NES Four Score just to rip connectors out of it or were reluctant to cut the ends off your NES controllers and use different connectors for your NES hack, you’re in luck. Parallax has released an NES controller connector (7-pin, male) that is compatible with the Nintendo controller. They also provide the socket pinout. It’s interesting to see a product like this come out so long after the original console, a testament to the popularity.

6 PC render farm in one clear case


Normally case mods are all show and no go, but [Fredrik Perman] and [Michael Stabile] took their old render farm and made it a working showcase for the front lobby. This is a perfect combination of function, beauty, and practicality. It is a great conversation piece, allows easy working access, and provides a tremendous space savings in one sweet looking wall-mounted case. The frame is aluminum, the back consists of sheets of polished diamond plate, with a clear acrylic sheet for a cover. The case sides are left open to allow the blue LED fans to circulate air. Cooling a render farm crammed in a closet can be quite difficult, but isn’t a problem with this open design. This build is also much prettier and maybe more manageable than the setup in ExtremeTech’s Build Your Own Render Farm article.

There are a few more pictures after the break.

Cloning and modifying E-Passports

[THC/vonJeek] have released an application that allow you to backup and modify E-Passport data.  Check out the video of Elvis checking in at the airport.  Apparently there is no way for the machine to know if the passport has been tampered with.

Buy a camera on eBay, get spy pics

This is a picture of MI6 headquarters. The people in that building are quite curious how a camera loaded with super mega secret stuff was auctioned off on eBay. Well, maybe they are more curious as to whom was doing the selling and how they acquired the camera. They’re investigating it now.

Cheap XY table using hobby servos

[CarlS] wanted to build a low cost x y table for display on teletoyland.com. He realized that to keep cost low, he could use hobby servos instead of stepper motors. Exact precision wasn’t a big issue here, so the hobby servos would be perfectly acceptable.

Though Linear hobby servos are available, he decided that the cost was prohibitive.  He used normal hobby servos, but had to modify their internals to get the exact amount of travel necessary. Many people modify the hobby servos for continuous rotation, but this would cause a loss in the ability for exact positioning. Instead, he replaced the potentiometer that measures the position of the servo with a 10 turn potentiometer. This allowed him 10x the travel.

PS3 Eye as a webcam on windows

The NUI Group has been working hard to bring the PS3 Eye to windows.  From the factory, this device has pretty impressive specs, but no windows drivers.  After a bit of hacking, they’ve developed a driver for it and released it on their forums.  The main reason they are so interested in it is that it can capture full frame at 60 frames per second, making it perfect for multi touch sensing.  Now that they’ve got it working with windows, they’re working on a custom PS3 Eye filter for touchlib.
