Retro hardware mash-up spouts archaic geekery

This delightful little box is something only a hacker could love. It uses some second-hand hardware to display random sayings attributed to [Buckminster Fuller]. The image above doesn’t do the display justice. There are other photos which show very crisp lettering which is easier to read.

[Autuin] always keeps his eyes open for cool gear at the end of its consumer life. The screen for this project is a CRT from a Coleman TV lantern (you know, for camping… bah!). It finds a home in the chassis of an old non-functional radio he had picked up a few years earlier. With those parts in hand the real adventure started: getting an Arduino to read in quotes and generate a TV out signal to display them.

We love the SD card holder which he fashioned from a card-edge connector he grabbed at the local electronics store. From there he scoured the Internet for help on where to patch into the TV signal. Once the right trace was discovered the Arduino TV out library does the heavy lifting.

Would you like to play a game?

[Itay] dropped a link in our inbox about creating a simple video game system using Arduino. Yes we all know where that is going … the TV out library for Arduino. However this tutorial should still be mentioned because it pretty much covers everything someone new would need to quickly and easily hook one of these things up, along with wii Nunchuck usage, library basics and creating your first game.

Lots of large pictures, diagrams, and explanation of software is included. Yes we know we feature this little setup a lot, that is because its so darn fun. So if you ever wanted to make your own little video game system (without going crazy bit banging VGA out of a little micro in ASM) this guide will help you get started making that next arcade masterpiece.

Adding video out to the Open Pandora

There’s very few users out there who actually have their hands on an Open Pandora Console. But the ones who do might find this hack useful for getting TV out up and running. It’s actually not hard at all, but if you don’t want to alter the hardware on the device you’ll first have to find a cable plug that will fit the EXT jack. This proved more difficult than it needed to be, since TI carries the connector but only sells them in multiples of 2200. A group buy was organized and we’d bet you can still get in on that action.

The connector in question carries TVout1 and TVout2 conductors. These correspond to the Luminance and Chrominance signals needed for the S-video protocol. But [MarkoeZ] wanted to use a composite connection. Turns out that’s not hard either, he hooked up the ground from the plug to the ground of the RCA jack, then connected both video lines to the center conductor, making sure to add an inline 470pf capacitor on the Chrominance side. Check out the demo video embedded after the break to see the final product.

Playstation 2 controller to PSP adapter

[TokyoDrift] built an adapter that allows you to connect a PlayStation 2 controller to a PlayStation Portable. It’s a bit different from similar hacks as this adapter doesn’t require any hardware alteration to the PSP or the controller. To do so, a plug-in is used on the PSP firmware side of things. The adapter then makes use of video out and PS2 controller extension cables, along with an ATmega8 microcontroller to handle the signals between the two devices. We posted a picture of the guts because we like that king of thing but the finished project is nicely housed inside of a project box. See for yourself in the video after the break.
