2025 Hackaday Speakers, Round One! And Spoilers

September 30, 2025 by 4 Comments

Supercon is the Ultimate Hardware Conference and you need to be there! Just check out this roster of talks that will be going down. We’ve got something for everyone out there in the Hackday universe, from poking at pins, to making things beautiful, to robots, radios, and FPGAs. And this isn’t even half of the list yet.

We’ve got a great mix of old favorites and new faces this year, and as good as they are, honestly the talks are only half of the fun. The badge hacking, the food, the brainstorming, and just the socializing with the geekiest of the geeky, make it an event you won’t want to miss. If you don’t have tickets yet, you can still get them here.

Plus, this year, because Friday night is Halloween, we’ll be hosting a Sci-Fi-themed costume party for those who want to show off their best props or most elaborate spacesuits. And if that is the sort of thing that you’re into, you will absolutely want to stay tuned to our Keynote Speaker(s) announcement in a little while. (Spoiler number one.)

Creating Python GUIs With GIMP

September 29, 2025 by 30 Comments

GUI design can be a tedious job, requiring the use of specialist design tools and finding a suitable library that fits your use case. If you’re looking for a lightweight solution, though, you might consider just using a simple image editor with a nifty Python library that [Manish Kathuria] whipped up.

[Manish’s] intention was to create a better-looking user interface solution for Python apps that was also accessible. He’d previously considered other Python GUI options to be unimpressive, requiring a lot of code and delivering undesirable results. His solution enables the use of just about any graphic you can think of as a UI object, creating all kinds of visually-appealing possibilities. He also was eager to make sure his solution would work with irregular-shaped buttons, sliders, and other controls—a limitation popular libraries like Tkinter never quite got around.

The system simply works by using layered image files to create interactive interfaces, with a minimum of code required to define the parameters and performance of the interface. You’re not strictly limited to using the GIMP image editor, either; some of the examples use MS Paint instead. Files are on Github for those eager to try the library for themselves.

We’ve featured some neat GUI tools before, too, like this library for embedded environments. Video after the break.

Two hands working a TekaSketch

TekaSketch: Where Etch A Sketch Meets Graph Theory

September 29, 2025 by 6 Comments

The Etch A Sketch was never supposed to meet a Raspberry Pi, a camera, or a mathematical algorithm, but here we are. [Tekavou]’s Teka-Cam and TekaSketch are a two-part hack that transforms real photos into quite stunning, line-drawn Etch A Sketch art. Where turning the knobs only results in wobbly doodles, this machine plots out every curve and contour better than your fingertips ever could.

Essentially, this is a software hack mixed with hardware: an RPi Zero W 2, a camera module, Inkplate 6, and rotary encoders. Snap a picture, and the image is conveyed to a Mac Mini M4 Pro, where Python takes over. It’s stripped to black and white, and the software creates a skeleton of all black areas. It identifies corner bridges, and unleashes a modified Chinese Postman Algorithm to stitch everything into one continuous SVG path. That file then drives the encoders, producing a drawing that looks like a human with infinite patience and zero caffeine jitters. Originally, the RPi did all the work, but it was getting too slow so the Mac was brought in.

It’s graph theory turned to art, playful and serious at the same time, and it delivers quite unique pieces. [Tekavou] is planning on improving with video support. A bit of love for his efforts might accellerate his endeavours. Let us know in the comments below!

Drones At Danish Airports, A Plea For Responsible Official Response

September 27, 2025 by 49 Comments

In Europe, where this is being written, and possibly further afield, news reports are again full of drone sightings closing airports. The reports have come from Scandinavia, in particular Denmark, where sightings have been logged across the country. It has been immediately suggested that the Russians might somehow be involved, something they deny, which adds a dangerous geopolitical edge to the story.

To us here at Hackaday, this is familiar territory. Back in the last decade, we covered the saga of British airports closing due to drone sightings. In that case, uninformed hysteria played a large part in the unfolding events, leading to further closures. The problem was that the official accounts did not seem credible. Eventually, after a lot of investigation and freedom of information requests by the British drone community, there was a shamefaced admission that there had never been any tangible evidence of a drone being involved.

Steamboat Willie Still Tests Copyright

September 26, 2025 by 18 Comments

If you know anything about Mickey Mouse, you’ll be able to tell us that his first outing was in 1928’s Steamboat Willie — an animated short that sees our hero as the hapless pilot of a riverboat battling an assortment of animals and his captain. It entered the public domain last year, meaning that it and the 1928 incarnation of Mickey are now free of any copyright obligation to the media giant.

There’s an interesting development from Florida on that front though as it seems Disney may have been testing this through legal means, and now a law firm wants to see them in court over their proposed use of the film in an advert.

Of course here at Hackaday we don’t cover the dry subject of Florida legal news as a rule, but we are interested in the world of copyright as it applies to many other things that do come under our eye. As we understand it the law firm is requesting the judge assert their protection from trademark claims over the use of Disney’s 1928 Willie, given that there have been claims from the entertainment giant against others doing the same thing.

It’s hardly surprising that a large corporation might seek to use legal muscle and trademark law to de facto extend the term of Mickey’s protection beyond the defined copyright expiration date, so for once it’s refreshing to see them come up against someone unafraid of a courtroom.

We hope that common sense will prevail, and this undermining of a cherished right (not to mention prior case law) is not allowed to succeed. Meanwhile if you’d like a 1928 Mickey that Disney have shied away from coming after, look no further than the EFF.

Radio Shack Rebirth May Have Gone Awry In Alleged Ponzi-Like Scheme

September 25, 2025 by 33 Comments

Oh, Radio Shack. What a beautiful place you once were, a commercial haven for those seeking RC cars, resistors, and universal remotes. Then, the downfall, as you veered away from your origins, only to lead to an ultimate collapse. More recently, the brand was supposed to return to new heights online… only to fall afoul of the Securities and Exchange Commission. (via Yahoo Finance, Bloomberg)

The Radio Shack brand was picked up a few years ago by a company known as Retail Ecommerce Ventures (REV). The company’s modus operandi was to take well-known but beleaguered brands and relaunch them as online-only operations. Beyond Radio Shack, REV also owned a number of other notable brand names, like Pier 1, Modell’s Sporting Goods, and Dress Barn.

Unfortunately, the Radio Shack rebirth probably won’t reach the stellar heights of the past. Namely, because REV has been accused of operating a Ponzi-like scheme by the SEC. Despite huge boasts allegedly made to investors, none of REV’s portfolio of brands were actually making profits, and the SEC has charged that the company was paying investor returns with cash raised from other investors — unsustainable, and a major no-no, legally speaking. In any case, the SEC charges apply directly to REV. The RadioShack brand has since been acquired by Unicomer Group, which operates the current online business, and has no ties to REV or its former operators.

We were cautiously optimistic when we heard about the REV buyout back in 2020, but at this point, it’s probably best to come to terms with the fact that Radio Shack won’t be returning to its former glory. The name will linger in our hearts for some time to come, but the business we knew is long gone. Sometimes it’s better to look to the future than to try and recreate the magic of the past, especially if you’re doing inappropriate things with other people’s money in the process.
