Receipt racer wastes a lot of paper

[Joshua Nobel] and the team at undef came up with a receipt printer game for the OFFF 2011 festival in Barcelona.

The game is a small openFrameworks app that prints a maze on a thermal printer. A ‘car’ is guided through the maze with input taken from a DualShock 3 controller. The game is limited to a maximum distance of 50 meters, the length of the roll of paper. We wondered about the waste of paper this would be until undef pointed out, “ecologically it’s pretty much a disaster, just like any real car.”

The undef team tried to use the printer for the entire visual representation of the game but that didn’t quite work out until [Joshua Noble] came up with a ‘beamer’ to project the car and score onto the paper. We’re not quite sure what the ‘beamer’ is, but everything syncs up and the resulting game is quite nice.

The game itself reminds us of a certain flash game, but that can’t be where the original idea came from. Check out the Receipt Racer gameplay video after the break.

Game Boy printer USB cable and software

[Furrtek] hooked up his Game Boy printer for use with a PC (translated). The two-part hack started with a cable to attach the device via USB. A Nokia interface cable was used as a base to translate the USB signals into serial, and an ATtiny45 microcontroller added to talk to the printer. He did a great job of free-forming the circuit alterations and fitting it back into the plastic USB plug housing.The next step was to write some software. Using VB6 he coded an application that loads in an image, scales it to fit, and allows you to adjust the contrast that the thermal printer produces. For testing purposes he’s reusing old receipts. See it in action after the break.

Receipt FAIL


Today’s fail comes courtesy of GNUCITIZEN‘s [pdp]. This would have made that TJX WEP crack much easier.
