[ViDAR] was looking for a project to keep him occupied and settled on creating a VGA converter for his Game Boy. He had some difficulty finding pinouts for the LCD and CPU but working with what was known, and an oscilloscope, he found the necessary signal. Tap into just a few lines using those thin blue wires; Vsync, Hsync, clock, and two data pins. From there a development board with an Altera Cyclone II field-programmable gate array takes care of the heavy lifting. The board already has hardware for a VGA connection so it was just a matter of processing the incoming signals into the VGA standard. His demo video is embedded after the page break.

In case you needed another reason to build, borrow, or buy a 3D printer, here’s one way to design and print your own cookie cutters. [Nikolaus Gradwohl] put together a processing app that aims to make the design process a bit easier. So if you’ve never designed a printable object before, but can get your hands on a MakerBot or similar device through a friend or your local hackerspace, this is for you. Check out the video after the break to see the process of making a cutter in the shape of a mushroom, or just download the app and give it a go.

Nookdevs have released information on how to root your nook color. So naturally, I had to run out and get one. Who doesn’t want a multitouch android tablet for $250? The instructions for rooting are extremely simple. You really only need microSD card and a Linux/Windows/Mac computer to connect to. After rooting, your nook will work exactly as it did before, but you can now install android applications on it. Many applications are built for a phone that has more physical buttons, so I have run into some issues, but over all, the applications that work tend to work well.
Join me after the break for more thoughts, a video of it in action, and a few pictures.

For Halloween [Paul] wanted to build a Jacob’s Ladder without the peril that working with high voltage might bring. He was inspired by a sequencer board for electroluminescent wire and decided to build a Jacob’s Ladder simulator using the glowing material. What he ended up with is quite convincing. Eight segments of EL wire have been mounted between two diverging towers. When a PIR sensor detects motion in the room, an Arduino switches on the simulation, playing a recording of the classic sizzling voltage sound while using the sequencer board to flicker the wires from bottom to top. See for yourself in the video after the break. We give [Paul] bonus points for constructing the base out of Lego.
But if you’re not one for being cautions, there’s always this real Jacob’s Ladder build. Or maybe you just want to make something glow with the EL wire.
