You Wouldn’t Steal A Font…

April 25, 2025 by 67 Comments

In the 2000s, the DVD industry was concerned about piracy, in particular the threat to their business model presented by counterfeit DVDs and downloadable movies. Their response was a campaign which could be found embedded into the intro sequences of many DVDs of the era, in which an edgy font on a black background began with “You wouldn’t steal a car.. “. It was enough of a part of the background noise of popular culture that it has become a meme in the 2020s, reaching many people with no idea of its origins. Now in a delicious twist of fate, it has been found that the font used in the campaign was itself pirated. Someone should report them.

The font in question is FF Confidential, designed by [Just van Rossum], whose brother [Guido] you may incidentally know as the originator of the Python programming language. The font in the campaign isn’t FF Confidential though, as it turns out it’s XBAND Rough, a pirated copy of the original. What a shame nobody noticed this two decades ago.

It’s a bit of fun to delight in an anti-piracy campaign being caught using a dodgy font, but if this story serves to tell us anything it’s that the web of modern intellectual property is so labyrinthine as to be almost impossible to navigate without coming a cropper somewhere. Sadly the people caught out in this case would be the last to call for reform of the intellectual property environment, but as any sane heads would surely agree, such reform is overdue.

If copyright gives you a headache, here’s our take on it.

A Bicycle Is Abandonware Now? Clever Hack Rescues Dead Light

April 24, 2025 by 77 Comments

A bicycle is perhaps one of the most repairable pieces of equipment one can own — no matter what’s wrong with it, and wherever you are on the planet, you’ll be able to find somebody to fix your bike without too much trouble. Unfortunately as electric bikes become more popular, predatory manufacturers are doing everything they can to turn a bike into a closed machine, only serviceable by them.

That’s bad enough, but it’s even worse if the company happens to go under. As an example, [Fransisco] has a bike built by a company that has since gone bankrupt. He doesn’t name them, but it looks like a VanMoof to us. The bike features a light built into the front of the top tube of the frame, which if you can believe it, can only be operated by the company’s (now nonfunctional) cloud-based app.

The hack is relatively straightforward. The panel for the VanMoof electronics is removed and the works underneath are slid up the tube, leaving the connector to the front light. An off the shelf USB-C Li-Po charger and a small cell take the place of the original parts under a new 3D printed panel with a switch to run the light via a suitable resistor. If it wasn’t for the startling green color of the filament he used, you might not even know it wasn’t original.

We would advise anyone who will listen, that hardware which relies on an app and a cloud service should be avoided at all costs. We know most Hackaday readers will be on the same page as us on this one, but perhaps it’s time for a cycling manifesto to match our automotive one.

Open Source Commercial Synthesisers You Will Love

April 23, 2025 by 17 Comments

Drumboy and Synthgirl from Randomwaves are a a pair of compact electronic instruments, a drum machine and a synthesiser. They are commercial products which were launched on Kickstarter, and if you’re in the market for such a thing you can buy one for yourself. What’s made them of interest to us here at Hackaday though is not their musical capabilities though, instead it’s that they’ve honoured their commitment to release them as open source in the entirety.

So for your download, you get everything you need to build a pair of rather good 24-bit synthesisers based upon the STM32 family of microcontrollers. We’re guessing that few of you will build your own when it’s an easier job to just buy one from Randomwaves, and we’re guessing that this open-sourcing will lead to interesting new features and extensions from the community of owners.

It will be interesting to watch how this progresses, because of course with the files out there, now anyone can produce and market a clone. Will AliExpress now be full of knock-off Drumboys and Synthgirls? It’s a problem we’ve looked at in the past with respect to closed-source projects, and doubtless there will be enterprising electronics shops eyeing this one up. By our observation though it seems to be those projects with cheaper bills of materials which suffer the most from clones, so perhaps that higher-end choice of parts will work in their favour.

Either way we look forward to more open-source from Randomwaves in the future, and if you’d like to buy either instrument you can go to their website.

Thanks [Eilís] for the tip.

A Blacksmith Shows Us How To Choose An Anvil

April 17, 2025 by 16 Comments

No doubt many readers have at times wished to try their hand at blacksmithing, but it’s fair to say that acquiring an anvil represents quite the hurdle. For anyone not knowing where to turn there’s a video from [Black Bear Forge], in which he takes us through a range of budget options.

He starts with a sledgehammer, the simplest anvil of all, which we would agree makes a very accessible means to do simple forge work. He shows us a rail anvil and a couple of broken old anvils, before spending some time on a cheap Vevor anvil and going on to some much nicer more professional ones. It’s probably the Vevor which is the most interesting of the ones on show though, not because it is particularly good but because it’s a chance to see up close one of these very cheap anvils.

Are they worth taking the chance? The one he’s got has plenty of rough parts and casting flaws, an oddly-sited pritchel and a hardy hole that’s too small. These anvils are sometimes referred to as “Anvil shaped objects”, and while this one could make a reasonable starter it’s not difficult to see why it might not be the best purchase. It’s a subject we have touched on before in our blacksmithing series, so we’re particularly interested to see his take on it.

A Cheap Yellow Display Makes A Video Walkie Talkie

April 14, 2025 by 5 Comments

The ESP32 series of microprocessors with their cheap high-power cores and built-in wireless networking have brought us a wide variety of impressive projects over the years. We’re not sure we’ve quite seen the like of [Jonathan R]’s video walkie talkie before though, a pair of units which as you might guess, deliver two-way video and audio communications.

The trick involves not one but two ESP32s: an ESP32-S3 based camera module, and a more traditional Tensilica ESP32 in a screen module. It’s an opportunity for an interesting comparison, as one device uses the Cheap Yellow Display board, and the other uses an Elecrow equivalent. The audio uses ESP-NOW, while the video uses WiFi, and since the on-board audio amplifiers aren’t great, there’s a small amp module.

The video below has a comprehensive run-down including the rationale behind the design choices, as well as a demonstration. There’s a small lag, but nothing too unacceptable for what is after all an extremely cheap device. Perhaps after all this time, the video phone has finally arrived!

Jenny’s (Not Quite) Daily Drivers: Raspberry Pi 1

April 14, 2025 by 47 Comments

An occasional series of mine on these pages has been Daily Drivers, in which I try out operating systems from the point of view of using them for my everyday Hackaday work. It has mostly featured esoteric or lesser-used systems, some of which have been unexpected gems and others have been not quite ready for the big time.

Today I’m testing another system, but it’s not quite the same as the previous ones. Instead I’m looking at a piece of hardware, and I’m looking at it for use in my computing projects rather than as my desktop OS. You’ll all be familiar with it: the original Raspberry Pi appeared at the end of February 2012, though it would be May of that year before all but a lucky few received one. Since then it has become a global phenomenon and spawned a host of ever-faster successors, but what of that original board from 2012 here in 2025? If you have a working piece of hardware it makes sense to use it, so how does the original stack up? I have a project that needs a Linux machine, so I’m dusting off a Model B and going down memory lane.

Repairing Classic Sound Cards

April 12, 2025 by 15 Comments

Sound hardware has been built into PC motherboards for so long now it’s difficult to remember the days when a sound card was an expensive add-on peripheral. By the mid to late 1990s they were affordable and ubiquitous enough to be everywhere, but three decades later some of them are starting to fail. [Necroware] takes us through the repair of a couple of Creative Labs Sound Blaster 16s, which were the card to have back then.

The video below is a relaxed look at typical problems afflicting second-hand cards with uncertain pasts. There’s a broken PCB trace on the first one, which receives a neat repair. The second one has a lot more wrong with it though, and reveals some surprises. We would have found the dead 74 series chips, but we’re not so sure we’d have immediately suspected a resistor network as the culprit.

Watching these cards become sought-after in the 2020s is a little painful for those of us who were there at the time, because it’s certain we won’t be the only ones who cleared out a pile of old ISA cards back in the 2000s. If you find one today and don’t have an ISA slot, worry not, because you can still interface it via your LPC bus.
