Limitations, Creativity, And Challenges

This week, we announced the winners for the previous Pet Hacks contest and rang in our new contest: The One Hertz Challenge. So that’s got me in a contesty mood, and I thought I’d share a little bit of soap-box philosophizing and inside baseball all at once.

The trick to creating a good contest theme, at least for the creative Hackaday crowd, is putting on the right limitation. Maybe you have to fit the circuit within a square-inch, power it only with a coin cell, or use the antiquated and nearly useless 555 timer IC. (Yes, that was a joke!)

There are two basic reactions when you try to constrain a hacker. Some instantly try to break out of the constraint, and their minds starts to fly in all of the directions that lead out of the box, and oftentimes, something cool comes out of it. The other type accepts the constraint and dives in deep to work within it, meditating deeply on all the possibilities that lie within the 555.

Of course, we try to accommodate both modes, and the jury is still out as to which ends up better in the end. For the Coin Cell challenge, for instance, we had a coin-cell-powered spot welder and car jumpstarter, but we also had some cool circuits that would run nearly forever on a single battery; working against and with the constraints.

Which type of hacker are you? (And while we’re still in the mood, what contest themes would you like to see for 2026?)

Announcing The Hackaday Pet Hacks Contest

A dog may be man’s best friend, but many of us live with cats, fish, iguanas, or even wilder animals. And naturally, we like to share our hacks with our pets. Whether it’s a robot ball-thrower, a hamster wheel that’s integrated into your smart home system, or even just an automatic feeder for when you’re not home, we want to see what kind of projects that your animal friends have inspired you to pull off.

The three top choices will take home $150 gift certificates from DigiKey, the contest’s sponsor, so that you can make even more pet-centric projects. You have until May 27th to get your project up on Hackaday.io, and get it entered into Pet Hacks.

Arduboy Cassette Award Explores New Features

When [Press Play on Tape] entered their game Prince of Arabia into the Arduboy FX Game Jam, we bet they had no idea that they’d be taking home a prize quite like this — designed by Arduboy creator [Kevin Bates], this gorgeous new variant of the handheld system brings some exciting new capabilities to the platform. Plus, it looks awesome.

The system, which is made up of a stacked pair of PCBs, has been designed to resemble an audio cassette. Thanks to the full-color silkscreen service offered by PCBway, it certainly looks the part. But it’s also a fully functional Arduboy, which means it has access to all the games already written for the 8-bit system.

Always Something New Under The Sun

Some of the entries we got into the Tiny Games Contest have been really mind-blowing. Just as you think you’ve seen it all, for instance, alnwlsn comes along and mills the DIP-package ATtiny84 and embeds a complete Simon game in the space normally wasted by all that plastic overmolding. It’s the tiniest, and most gonzo, circuit-sculpture Simon we’ve ever seen.

Soldering fine wires to the leadframe of an ATtiny84 in a DIP-14 package.Now, our judges are hard at work ranking all 80 of the entries, and we have a fantastic range of entries all around, so I’m not calling any winners yet. But have you ever seen a project milled into a chip before? Nope, me neither.

What’s amazing is that this happens every time we run a contest. The second you put limitations on a project, there’s always someone out there who says “Hold my beer” and blows the limits out of the water. Indeed, the frequency with which we see someone pull off the impossible on Hackaday makes me wish I were buying more lottery tickets. You all really are stupendous.

We hope that feats like this are as inspirational to you as they are to us. No idea is too bonkers to not at least give it a try. Who knows, it might work! And when it does, please write it up and let us know. Keep the cycle of inspiration going!

Show Us Your Minimalist Games, And Win

Sometimes the tightest constraints inspire the highest creativity. The 2024 Tiny Games Challenge invites you to have the most fun with the most minimal setup. Whether that’s tiny size, tiny parts count, or tiny code, we want you to show us that big fun can come in small packages.

The Tiny Games Challenge starts now and runs through September 10th, with the top three entries receiving a $150 gift certificate courtesy of DigiKey.

Congratulations To The 2024 Business Card Challenge Winners!

When you ask a Hackaday crowd to design a business card, you should expect to be surprised by what you get. But still, we were surprised by the breadth of entries! Our judges wracked their brains to pick their top ten, and then we compared notes, and three projects rose to the top, but honestly the top ten could have all won. It was a tight field. But only three of the entries get to take home the $150 DigiKey gift certificates, so without further ado…
