You Gotta Want It

August 22, 2026 by Elliot Williams 20 Comments

On Hackaday last week, and on the podcast, we were talking about one of the educational toys of yesteryear that launched a thousand careers, at least if the comment section is to be believed: the Radio Shack 200-in-1 electronics kit. The “toy” itself was basically a bunch of components with spring terminals, but the secret sauce was in in the instruction book, and maybe the marketing.

Tom had one of these when he was a kid, and told a great story about wanting it desperately based on the ads he had seen with kids Morse coding to each other. When he got the kit, and found out that “it was just a bunch of wires” he was fully pissed off. But he worked through the examples, learned some basic electronics, and the rest is history.

What I really love about this story is the siren’s call of a good project. Tom was pulled in, and maybe even fooled, by the advertising, but it probably changed his life. It’s funny how many of our folks can remember the first project that got them hooked as well. With me it was some simple audio effects pedals and then maybe later some simple BEAM robots, and for younger hackers maybe it was a 3D printer or Arduino project.

Digital or analog, the common ground here is that we all thought that some project was cool enough to warrant the sweat of learning enough to do it. Good instructions are helpful of course, and having the parts on hand never hurts. But it’s the promise of making something that you really want that I think underlies all good first projects. (And heck, every subsequent project as well.)

So while Tom, and a bunch of our readers, were looking back with nostalgia at the 200-in-1, I’m thinking about how many more than 200 projects I’ve seen made by our community, and even featured here on Hackaday, that are out there to provide the motivation to get someone started. Keep on hacking!

For Art’s Sake

March 28, 2026 by Elliot Williams 13 Comments

Hackers can be a strange folk. Our idea of beauty, for instance, can be rather odd. This week, Hackaday saw a few projects that were not just functional – the aesthetics were the goal. I don’t think we’ll be taking over the fine art world any time soon, but I’m absolutely convinced that the same muse that guides the hand that holds the paintbrush sometimes also guides the hand holding the soldering iron.

Take “circuit sculpture”, for instance. Heck, we even give it an art-inspired name that classifies it correctly. This week’s project that got me thinking about the aesthetics of hand-bent wire circuits was this marvelous clock build, but the works of Mohit Bhoite or Kelly Heaton are also absolute must-sees in this category.

Outside of the Hackaday orbit, one of my all-time favorite artists in this genre was Peter Vogel, who made complex audience-reactive sound sculptures that looked as good as they sound.

Is a wireframe animated moving jellyfish art? It was certainly intended to be beautiful, and I personally find it so. Watch some of the video clips attached to the project to get a better sense of it.

In the sculpture world, there is a sub-genre of kinetic art pieces where the work itself is secondary to the beauty of the motions that the pieces pull off. Think ballet, but mechanical. Perhaps my absolute favorite of these artists is Arthur Ganson. If you haven’t seen his work before, check out “Thinking Chair” for the beauty of movement, but don’t miss “Machine with Concrete” if you’re feeling more conceptual.

If you’re willing to buy an insane geartrain as art, what about these 3D printed wire strippers? Is this “art”? It’s clear that they were designed with real intent and attention to the aesthetics of the final form, and am I wrong for finding the way they move literally beautiful?

99% Partspiration

July 8, 2023 by Elliot Williams 37 Comments

Thomas Edison once said that genius was 1% inspiration and 99% perspiration. That doesn’t leave much room for partspiration.

I’m working on a top-secret project, and had to place a parts order on AliExpress with a minimum order quantity of five in order to get decent shipping times. No big deal, financially, and it’s always great to have spares as backup for the ones you fry.

But as I started lighting up the little round smartwatch displays to put them through their paces, I started thinking of all sorts of ways that I could use something like this. I had no idea how easy to drive they were, or frankly, how good they looked in person. When you get a round display in your hands, you find that you need dial indicators everywhere.

And then my son came by and said “Oh neat. I want one!” and started thinking up all sorts of gizmos that I could put them in. Two of them would make awesome eyes, and he’s been on a chameleon kick – the animal, you know. So we’re looking for chameleon eye animations online.

And all of a sudden, I have more projects lined up than I have remaining screens. I’m calling this phenomenon “partspiration”. You know, when you figure out how to use something and then you see uses for it everywhere? Time to place another Ali order.

Gearing Up for the Hackaday Prize

And don’t forget, we just started the next round of the Hackaday Prize: Gearing Up. In this challenge round we want to see your best DIY tools, jigs, and workflow accelerators. Custom reflow plates, home-built power supplies, or even software tools – as long as it helps you get the job done, it has a place here. You’ve got until Aug. 8 to get your entry finished, but head on over to Hackaday.io and get started now.

Badminton Inspired Heat Shield Aims To Fly This Year

May 18, 2023 by Bryan Cockfield 15 Comments

Badminton is not a sport that most of us think about often, and extremely rarely outside of every four years at the summer Olympics and maybe at the odd cookout or beach party here or there. But the fact that it’s a little bit unique made it the prime inspiration for this new heat shield design, which might see a space flight and test as early as a year from now.

The inspiration comes from the shuttlecock, the object which would otherwise be a ball in any other sport. A weighted head, usually rubber or cork, with a set of feathers or feather-like protrusions mounted to it, contributes to its unique flight characteristics when hit with a racquet. The heat shield, called Pridwen and built by Welsh company Space Forge, can be folded before launch and then expanded into this shuttlecock-like shape once ready for re-entry. It’s unlikely this will protect astronauts anytime soon, though. The device is mostly intended for returning materials from the Moon or from asteroids, or for landing spacecrafts on celestial bodies with atmospheres like Mars or Venus.

With some testing done already, Space Forge hopes this heat shield will see a space flight before the close of 2023. That’s not the end of the Badminton inspiration either, though. It’s reported that this device can slow a re-entering craft so much that it can be caught in a net. Not exactly the goal when playing the sport, but certainly a welcome return home for whichever craft might use this system. Of course, getting down from space is only half the battle. Take a look at this other unique spacecraft that goes up in a fairly non-traditional way instead.

Honor Your Hacker Heroes

September 24, 2022 by Elliot Williams 3 Comments

We recently ran an article on a sweet percussion device made by minimal-hardware-synth-madman [Gijs Gieskes]. Basically, it amplifies up an analog meter movement and plays it by slamming it into the end stops. Rhythmically, and in stereo. It’s got that lovely thud, plus the ringing of the springs. It takes what is normally a sign that something’s horribly wrong and makes a soundtrack out of it. I love it.

[Gijs] has been making electro-mechanical musical hacks for about as long as I’ve been reading Hackaday, if not longer. We’ve written up no fewer than 22 of his projects, and the first one on record is from 2005: an LSDJ-based hardware sequencer. All of his projects are simple, but each one has a tremendously clever idea at its core that comes from a deep appreciation of everything going on around us. Have you noticed that VU meters make a particular twang when they hit the walls? Sure you have. Have you built a percussion instrument out of it? [Gijs] has!

Maybe it’s a small realization, and it’s not going to change the world by itself, but I’ve rebuilt more than a couple projects from [Gijs]’ repertoire, and each one has made my life more fun. And if you’re a regular Hackaday reader, you’ve probably seen hundreds or thousands of similar little awesome ideas played out, and maybe even taken some of them on as your own as well. When they accumulate up, I believe they can change the world, at least in the sense of filling up a geek’s life. I hope that feeling comes across when we write up a project. Those of you out there hacking, we salute you!

Inspiring Hacks, Unfinished Hacks

March 26, 2022 by Elliot Williams 5 Comments

We got a tip this week, and the tipster’s comments were along the lines of “this doesn’t look like it’s a finished work yet, but I think it’s pretty cool anyway”. And that was exactly right. The work in question is basically attaching a simple webcam to a CNC router and then having at it with OpenCV, and [vector76]’s application was cutting out freeform hand-drawn curves from wood. To amuse his daughter.

But there’s no apology necessary for presenting a work in progress. Unfinished hacks are awesome! They leave room for further improvement and interpretation. They are like an unfinished story, inviting the hacker to dream up their own end. At least that’s how this one worked on me.

My mind went racing — adding smart and extensible computer vision to a CNC router enables not only line tracing, but maybe smarter edge finding, broken tool detection, and who knows what else. With the software end so flexible these days, and the additional hardware demands so minimal, it’s an invitation. It’s like Pavlov ringing that bell, and I’m the dog-hacker. Or something.

So remember this when you get half done with a project, get to a workable first-stage demo, but you haven’t chased down each and every possibility. Leaving something up to other hackers’ imagination can be just as powerful. Your proof of concept doesn’t have to be the mother of all demos — sometimes just a working mouse will suffice.
