Lost Version Of Amiga Unix Suddenly Reappears

Some of you may know there’s a version of UNIX for the Commodore Amiga, aptly called Amiga Unix or AMIX. There is an almost complete record of versions from 1.0 to 2.03, but 2.02 was lost media–until [Forgotten Computer] found it on an old Amiga.

It starts with an auction held for the 40 year anniversary of the Free Software Foundation where, by just one second, the highest bidder was too late. What do you do first with an artifact as valuable as an old FSF computer? You image the hard drive. Then you make several copies, including on different computers–after all, you wouldn’t want to lose the data on it. Preservation secured, the natural next thing is to boot it–and that’s when we see the magic 2.02c version number.
According to thorough digging by [Forgotten Computer], this version was–until now–lost.

In the video after the break, [Forgotten Computer] goes over what Amiga Unix is, the discovery process, and explores what’s on the disk–including FSF staples like GCC, G++ and core utilities like GNU less.

NoiseCloud: Storing Data On YouTube

Storage is expensive these days, whether you’re looking at the prices of spinning rust or magic little sticks of silicon. But what if there was some benevolent overlord that you could trick into giving you unlimited storage? That’s where Noisecloud comes in.

Created by [Lucas], Noisecloud is a tool that lets you use YouTube as a form of effectively-unlimited file storage. It works by taking whatever file data you have on hand, and turns it into frames of digital noise that can be stored and transported as an MP4 file and uploaded to YouTube. The encoding process involves first compressing the data with gzip, then packaging it into a high-constrast series of video frames that are then encoded with FFmpeg. Video containers can be produced in various resolutions, all the way down to 640×360 @ 30 fps. There’s also a special “TikTok mode” which is optimised to best preserve data on short form sites that use vertical orientation as default. More commentary from the creator is available via the supporting article on Github.

It’s probably not a practical way to store your files, given the fussy encoding and decoding required to actually use the data. However, it’s an interesting proof of concept that explores how data can be stashed in unexpected places via publicly-accessible services. We’ve explored similar work before, too.

Adding Capabilities To Inexpensive Solar Modules

Solar power has gotten cheap enough that putting up panels is among the cheapest ways of providing energy. This isn’t just the case for bulk electricity on a power grid, either; even small devices are easier and cheaper to power with solar than ever before. For example, landscape lighting which once relied on 12V or 24V DC wires all over one’s yard with a transformer and power supply hidden somewhere have partially been converted to simpler individual solar-powered lights now. These small devices can also be given additional capabilities as [Mauro] demonstrates.

In this case, [Mauro]’s goal was to add on-demand lighting to a solar-powered light which was otherwise motion-activated only. To do this, they added a NRF24L01+ radio inside the light’s housing paired with an STM32 microcontroller. This secondary system is largely separated from the existing control circuitry with the exception of being able to switch the lights and receiving its power from the same solar panel. [Mauro] also created a small library to help with communicating with these new modules, whether that’s using a home automation system like Home Assistant or some other method.

Although adding in a few capabilities to inexpensive solar lighting might seem simple on the surface, a project like this is a gateway to adding in all kinds of interesting features to things with built-in solar panels and lots of free space in their cases. The best example here is the addition of a Meshtastic node to one of these lights, making it convenient and stealthy, but we could also see adding in other remote hardware to a landscape lighting module like a gate sensor or a plant health monitoring system.

2026 Hackaday Europe: Pre-party, More Workshops, And Everything Else

With Hackaday Europe no more than two days away, we want to help you wrap up all of the last loose ends. And that means last-minute changes in the workshop schedule, details on the Friday night pre-party, and more! Some tickets for the event itself, the workshops, and the pre-party (reservations required) are still available right here.

Pre-Party, Friday May 15th

Kick off the weekend with us at the official Hackaday Europe pre-party at Soqquadro Restaurant, Piazza Era 7, 23900 Lecco, Italy. Enjoy the Italian aperitivi on the gorgeous Lago di Lecco waterfront. Your ticket includes two drinks and an array of delicious snacks. It’s the Italian way to pregame the weekend ahead. Bring a hack, or just relax and hang out. Your choice. Either way, make sure you pre-register. (On the preregistration page, scroll all the way down past the workshops.)

Workshops

Unfortunately, the Let’s Mesh workshop has been canceled, but the good news, thanks to our incredible sponsors, we’ve added two great new workshops to the lineup. On Saturday, May 16th, we’ll have Tiny Tapeout, When Code Needs a Body, and Fault Injection 101. Sunday features EchoGlow: Arduino UNO Q Workshop with the brand-new Arduino Q devices, from 11:00 AM – 2:00 PM.

Tickets and full descriptions are available at registration.

Lightning Talks

On Sunday afternoon, we’ll dedicate some time to Lightning Talks. These are short, seven-minute talks, with or without slides, on whatever interests you at the moment. If you’ve got hacks or deep thoughts to share with us, you’ll never find a more receptive audience. Register now! Talk slots are FIFO.

Thanks, and See You Soon!

If you’ve never attended a Hackaday event before, we’re excited to see you. Half the fun is the crowd that convenes. If you want to bring along a hack to informally show-and-tell, it’s a great icebreaker. You won’t have to bring food or drinks – we’ve got that covered all weekend.

If you’re an old Hackaday hand, we’re stoked to see you again! A first at Hackaday Europe is going to be whatever large fraction of our SAO collection fits into carry-on luggage, and a sweet-looking SAO wall made by Hackaday Superfriend [Thomas Flummer]. If you have an SAO that you’d like to add to our pile, bring it along! It’s about time for us to do a photo gallery and write-up of everything we’ve got.

And we can’t leave without thanking our broad array of sponsors who make Hackaday Europe possible:

The Walls Don’t Have Ears, But Fiber Optic Does

You normally think of fiber optic as something used in network cables. However, scientists employ dedicated fibers to detect earthquakes. In simple terms, they fire a laser down the fiber and watch reflections caused by imperfections. When vibrations hit the cable, it changes the defects, which show up in the return pattern. However, with the right techniques, those vibrations could just as easily be from people speaking near the cable.

If you are alarmed, there’s good news and bad news. The good news is that the technique seems to be limited to coils of fiber that are not buried, and you have to be within about 5 meters of the fiber. The bad news is that there is plenty of dark cable all over the place. Besides, if researchers can do this successfully, you would imagine three-letter agencies around the world could do it even better.

Honda Wants To Complicate Your E-Motorcycle

If you ride a motorcycle, you know it is a bit of an art to manage the transmission on a typical bike. Electric motorcycles lose some of that. You usually just have a throttle and a brake. No transmission and, crucially, no clutch. Honda just patented a simulated clutch for those who want the old-school experience, according to [Ben Purvis], writing for Australian Motorcycle News.

This isn’t just a do-nothing lever on the handlebar. There’s haptic feedback to feel when the clutch engages. The motor responds to your actions on the lever. If you pull the clutch in part of the way, the motor loses power up to the point where there is no engine power with the clutch fully in.

You’ve Seen The Chip Shortage And The Memory Shortage, Now Prepare For The PCB Shortage

It’s nice to hide away in our little corner of the internet and talk tech, safely away from the turmoil of world events. Sometimes though, geopolitics intrude even into our space, and Reuters are here reporting on a new concern that will probably affect many Hackaday readers. Conflict in the Gulf of Arabia, and in particular raids on Saudi petrochemical plants, is threatening PCB production far away in China.

Most of us probably have a mental image of tankers sailing through the Strait of Hormuz laden with Gulf crude, off to be processed by refineries somewhere else in the world. Certainly a load of oil takes just that route, but for the Saudis and other oil-producing nations in the region, it also makes economic sense to site petrochemical industries at source. They export the much more valuable refined products, among which is the polymer resin used in PCB production. The Reuters report says that consequent to this and a rise in copper prices, the cost of a PCB in China has risen by 40%. Naturally this doesn’t sound like good news.

Here at Hackaday, when it comes to component shortages this isn’t our first rodeo. We’re in the middle of a memory shortage due to AI companies, and the COVID-era chip shortage is still fresh in our minds. Unfortunately, this type of thing as been a regular of the technology world for decades. Here we are with another one, and should we be worried? In the short term it’s certainly a concern as the Gulf conflict is still searching for an end to its uneasy stalemate, but remembering previous shortages we think that global industry will adapt and expand other sources where necessary. Just as with the similar IC encapsulation resin shortage back in the ’90s, it may eventually be the panic more than the shortage which becomes responsible for the price hikes.

We’ve taken an abstract look at global electronic supply chains before.
