A Square Inch Of Nyan

Over on Hackaday.io, there’s an unofficial contest to cram as much electronics and awesome as possible into a single square inch of PCB. While the measurement system is logical, the Internet is not: it feeds on cats and is entertained by rainbows. [Radomir]’s project feeds into this bizarre fixation with the Nyan Board, a Pop Tart cat that poops rainbows, all the while playing bleeps and boops that would fit well in a Nintendo game.

[Radomir] built this square inch of twee for the square inch project, an unofficial contest to fit the coolest project on a 1×1 inch square PCB. Prizes are credits for the Hackaday Store and OSHPark. This entry uses an ATtiny85 microcontroller, a few resistors, LEDs,  and a buzzer to play the strange, syncopated Nyan theme song. Power is delivered over a colorful ribbon cable that emulates the rainbow tail of the Pop Tart cat.

This isn’t the only project in the Square Inch Project, or even the most blinky; there’s also a RRROYYYYgYgGGBgBPW LED, a square inch quadcopter, and a device that detects the world’s smallest bat. All very interesting projects, and we can’t wait to see all the entries finished.

Embroidered Nyan Cat Brings A Meme To The Real World

Have you ever come across an Internet meme and just thought to yourself, “I have to bring this into the physical world!” Well [0xb3nn] and [Knit Knit] did. They decided to take the classic nyan cat meme and bring it to life.

The frame is 24″ x 36″. Many hours went into the knitting process, but the result obviously turned out very well. The stars include 24 LED sequins to add a sparkling animation effect. These were sewn onto the back of the work using conductive thread. They are bright enough to shine through to the front where needed. These connect back to an Arduino Pro Mini 5V board.

The Arduino is also connected to a capacitive touch sensor. This allows the user to simply place their hand over the nyan cat image to start the animation. No need for physical buttons or switches to take away from the visual design. An Adafruit AudioFX sound board was used to play back a saved nyan cat theme song over a couple of speakers. The source code for this project is available on github. Be sure to watch the demo video below. Continue reading “Embroidered Nyan Cat Brings A Meme To The Real World”

Meme Themed Pinball Machine – Much Flipping, Y U No Win?!

Summoning 4chans, 9gags, Reddits and other denizens of easily-digested content, Liberty Games stripped apart a dilapidated “Baby Doll” pinball arcade machine and turned it into this meme-spouting monstrosity. A complete redo of the vinyl and graphics to sport dozens of familiar internet tropes was first, then they had Shapeways create internal scenery and finally some electronics were added to spice things up.

We have seen PINMAME-based digital machines but this took a different path. Pinball machines this old pre-date common transistors so they rely on electro-mechanicals for everything. This made hacking the machine challenging so the team intercepted most of the signals and tied them into a Raspberry Pi with a Pi-face interface board. A videoscreen was added to the scoreboard, triggering all manner of memey videos and sounds according to actions performed and unlocked on the screen.

If you yearn for expired pranks of years gone by and are bad at pinball, you are in luck. Losing the game gets you Rickrolled – over and over again. On the plus side, Nyan Cat rockets away to bonuses and even the Admiral himself warns you of impending danger.

We resisted the urge to write this article as a chain of one meme to the next, you will get plenty of that from the well-documented project conversion and the following video. Someone in the comments will probably make a list of all memes.
