Emulating The IPod

August 26, 2026 by 1 Comment

These days there are emulators for all the great consoles of yesteryear, as well as old retrocomputers and arcade machines and so much else to boot. Now, though, a particularly popular MP3 player has an emulator of its own—by the name of clicky!

The name is a reference to the click wheel of the venerable Apple iPod, and as you might imagine, that’s precisely what clicky is built to emulate. [daniel5151] started the project as a neat technical challenge, following on from earlier work he’s done in the NES emulation space. The iPod is a bit of a difficult prospect to emulate, being very much a closed-source device that is very poorly documented in the public space. There are few projects to look to for help, since a complete open-source iPod emulator doesn’t already exist; however, various alternative firmware projects have offered a guiding light.

For now, clicky can boot into RetailOS, which is what you would have used on an iPod you bought from the factory. It can also run Rockbox and iPodLinux, though for now, running the Apple Diagnostics program is not yet achievable. Plenty of functionality still isn’t implemented, either, like USB communication or even audio, which was the iPod’s whole raison d’être. Still, you can play some Brick Breaker like it’s 2006 if you’ve been missing it badly.

We see all kinds of emulators around these parts; this 60 FPS NES emulator running on a microcontroller was a particularly impressive recent effort. If you’re cooking up your own emulators for unique platforms, or unique emulators for non-unique platforms, let us know on the tipsline!

How Packaging Can Kill An Electronics Microbusiness

August 26, 2026 by 17 Comments

Quite a few in our community make a bit of cash on the side by selling our creations, and it’s not uncommon to find that a project which catches your eye can be picked up as a kit for a few of your preferred currency units. But there’s a problem facing such tiny producers in the form of regulations intended for large businesses which are beyond their ability to comply with. [Alain Pannetrat] writes for the Lectronz marketplace about one of them, the new European Union packaging waste regulations.

At face value it sounds like a good idea, that suppliers should be responsible in some way for the disposal of their packaging. It discourages excessive packaging and encourages recycling, indeed the EU even describe the scheme as boosting business. The problem is that its administration is left to individual member states, and someone selling across the whole bloc would have to join multiple schemes. The hefty price is nothing to a large enterprise, but impossible for a tiny one. He makes a very good point, that it’s difficult to claim to champion innovation, while also imposing something like this on grass-roots innovators. Going by the experiences of our acquaintances in this space an extra burden on top of that presented by the current unstable tariff and customs situation involved in selling to the USA would likely be the straw which broke the camel’s back.

In practice we suspect that many are simply doing the same as they have with compliance marking and waste electronic equipment regulations, simply not bothering and hoping they fly under the radar and never get caught. We hope we won’t end up reporting on any future crackdown, the landscape has definitely changed since we tried our hand in this business.

Hackaday Europe 2026: PCBs With A Plot

August 26, 2026 by No comments

Printed circuit boards were developed first for function over form. They were a way to mount components and connect them in a stable, robust fashion, while taking into regard things like packaging and cooling requirements to enable a circuit to function. Circuit boards often end up looking cool in a techy kind of way, but their aesthetic is usually very much secondary to their actual purpose.

Katrin Dietzsch likes to use her PCBs a little differently, however. She designs boards that are intended to be a narrative tool for tabletop roleplaying, and came down to Hackaday Europe 2026 to walk us through the development of this very whimsical hardware.

Claude Plays DOOM

August 26, 2026 by 22 Comments

Large language models (LLMs) are generally thought of as machines that accept textual prompts and spit out textual content. However, if you’re creative in the way you interface with them, you can get them to do a wider range of tasks. For example, [Andrea Ricci] figured out how to get one to play DOOM.

For this project, [Andrea] began by porting the game to the SCINTIX P4. It’s a rather interesting device, being a single board designed in the Raspberry Pi CM4/CM5 form factor, but carrying an ESP32-P4 and an ESP32-C6 instead. The game runs on the P4 and is displayed on a 1024×600 MIPI DSI panel, but it’s only stepped through a few frames at a time. These frames are then passed to Claude Sonnet via a WebSockets setup. With only the same information as a human player would get, the LLM has to figure out what it’s looking at, and then respond with movement and fire commands to play the game.

It’s quite interesting to watch the system play—the LLM mostly accurately describes the game world, navigates down corridors, opens doors, and shoots at enemies. There is a bit of work behind the scenes to enable it to see and understand the game world—namely, using a depth fan across the field of view so it can figure out where walls are and how not to bang into them. There’s also an ASCII automap used to allow the system to keep track of where it has already been. But fundamentally, the LLM is playing the game without any other sort of additional assistance.

We’ve seen some other great ways in which AIs have been whipped up to play various games, like Trackmania.

New Controller Makes Heavy Machinery Intuitive

August 26, 2026 by 24 Comments

As children, many of us looked wistfully into the cockpits of heavy machinery, wondering just how the series of knobs and levers would do something like operate a bulldozer, crane, or excavator. The nature of these myriad of hydraulic and electronic controls for equipment like this is often inscrutable to adults as well; it takes a considerable amount of training to be able to competently operate most of these machines. But this new controller from MIT may help shorten that training time.

The controller is specifically meant for excavators. In a standard excavator, a pair of joysticks is typically used, with one controlling the swing and the boom and the other controlling the stick and the bucket. Getting used to this combination can take practice, so instead the group of researchers replaced them with a model excavator arm that the operator controls directly with their own arm. The new controller is more intuitive to use as it translates the movements of the model to that of either a real excavator or a training simulation.

The researchers plan to include haptic feedback in future versions, which will hopefully further increase the ease of which new operators can get a feel for using these machines. For those not working towards a new career or an ambitious weekend with rental equipment, there are some other ways of learning how to operate excavators and other pieces of heavy machinery.

Blow Those Pyros With A Telephone!

August 25, 2026 by 15 Comments

A pyrotechnic charge is set off by passing a high voltage through a filament within it, melting the filament and igniting the charge. We could think of a variety of circuits that could do this, but perhaps we wouldn’t have come up with [Michał Słomkowski]’s solution. He’s used the ringer crank generator from an old military field telephone. It’s an old project he’s shared with us due to its recent republishing on his website.

The basic principle is simple enough, winding the generator charges a capacitor bank through a bridge rectifier. Then a thyristor is used as the trigger device, dumping the contents of the capacitor into the filament. But the full circuit has a couple of refinements. There’s a charge indicator circuit using a couple of Zener diodes and an LED, and a filament tester which passes a non-triggering current through the filament from a 9 volt battery. We like the use of an over-the-top high-current thyristor, no doubt what he had in his junk box.

Perhaps it’s a symbol of how far technology has moved, that today it’s surprisingly rare to find a bridge rectifier or a thyristor, and building this device today would involve a microcontroller and probably an AliExpress inverter module as a matter of course.

Meanwhile, should field telephones interest you, we’ve been there before.
