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.

The best part? the ribbon cable that matches the rainbow (more or less) XD
All around this is great use of aesthetics. The rainbow cables as you mentioned, SMD LED eyes, and use of the silk screen and copper holdoff to see the substrate on the top side. Really artistic work!
Yes +10 internet points awarded
Well that’s totally useless but as cute as f**k, I say it;s a winner!
This is awesome.
Radomir deserves to win the Hackaday prize for this ! Congratulations my friend ! :-)
This might be the most annoyance per square inch EVER. Where can I get six?
Yes, book it for the HaD Store!
I’m afraid there are copyright/trademark issues involved with selling such things.
Okay, so we’ll call it Ryan’s Rainbow Kittyand change a couple of musical notes… B^)
The code on your site is the Rick Role theme….
Check the alternate folder.
Also, well played dasheep.
Me: Okay, there are 3 entries, and 5 or 6 prizes to be awarded, a blinky light, and I win!
Me: Doh! Brain, did I just post that?
Brain: You sure did!
Make the arduino tone lib work on an attiny and we’ll talk again ;)
That’s exactly how I made it.
me knoes… I was replying to Ren that it isn’t ‘only’ blinking.
Oh, I know, it does more than that, I was aiming for the lowest rung on the ladder…
i.e. What can I get by with, and still get some serious schwag! B^)
wuahhhh. I’m sorry, I read it in the tone of the average blog commenter and also to reply I just hit the report comment by accident. Sorry, not my day :( I’d suggest you checkout the competition. I love blinky stuff and am a judge, just saying :D
and there are currently 46 entries :)
Time for a “Hacklet”!
OMG THIS IS AMAZING!! :D
thanks for the credits :)
No tiny CPU to compress the music as 2-bit ADPCM feeding an 8-bit DAC to get annoying sound to go with it. I WOULD buy one…. if they were cheap I would buy 4 – a GREAT stocking-filler.
This is all kinds of awesome I absolutely love it and would buy this ten times. I can’t wait to enthuse about this next to the water cooler in the morning to anyone who’ll listen.
