Minimum Viable 1-D PONG

What makes a game a game? Like, how do we know that we’re looking at a variation of PONG when confronted with one? And how do we know how to play it? [Bertho] sought to answer this question as he designed what is probably the smallest-ever 1-D PONG game. His answer involves charlieplexing LEDs, using a voltage divider to save I/O pins, and a couple of AAAs that should last for a long, long time.

[Bertho]’s Minimum 1-D PONG, or m1dp for short, puts an ATTiny85 through its paces as gameplay quickly progresses from ‘I got this’ to ‘no one …read more

Wire-bots, Roll Out!

Designing and 3D-printing parts for a robot with a specific purpose is generally more efficient than producing one with a general functionality — and even then it can still take some time. What if you cut out two of those cumbersome dimensions and still produce a limited-yet-functional robot?

[Sebastian Risi] and his research team at the IT University of Copenhagen’s Robotics, Evolution, and Art Lab, have invented a means to produce wire-based robots. The process is not far removed from how industrial wire-bending machines churn out product, and the specialized nozzle is also able to affix the motors to the …read more

Video Games In As Few Dimensions As Possible

First there were text games, then came 2D dungeons. When Wolfenstein 3D broke out on the gaming scene, it created quite a fuss. But if all you’ve got is a strip of WS2812 LEDs, those are a few dimensions too many.

[treibair] has started up a project on Hackaday.io to start working on 1D video games to be played on a single LED strip. While the end application is something with a cool physical interface, probably driven by a microcontroller, prototyping is a lot easier on the big computer. He’s writing it in Processing, though, so that the transition to …read more
