Making An LCD UI Look More Like Classic Indicator Lamps

Making An LCD UI Look More Like Classic Indicator Lamps

The TermDriver 2 is a USB-to-serial interface with a twist—it has a built-in screen for displaying relevant information. It can run at anywhere from 100 bit/s to 2Mbit/s, while showing you what’s happening on the wire. [James Bowman] worked on the TermDriver 2, and paid special attention to one feature—the visual look of the status indicators on the display.

[James] had hoped to make the status indicators look a little more old-school, a little more analog. His inspiration was the classic indicator panels from Apollo-era space hardware, which used bulbs behind plastic indicators. Incandescent bulbs don’t switch instantly on and off; they take time to warm and cool. This behaviour is both more pleasant, visually speaking, and would aid in making short-duration events on the TX, RX and other indicators more visible. Thus, [James] set about giving the LCD UI elements sixteen steps of brightness from off to fully on. The simulated bulbs get brighter the more rapidly activity is happening on a given pin. The indicator graphics, while tiny, are also given a nice superellipse shape, to recreate the warm centered glow of an incandescent indicator.

If you’re a UI fanatic who loves to make things as visually pleasing as possible, the work [James] has done is well worth looking at. We’ve featured other great GUI projects before, too, like this particularly visually pleasing effort. If you’ve had grand ideas in this space, be sure to tell us over on the tipsline.


Emulating the iPod

Emulating the iPod

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

How Packaging Can Kill An Electronics Microbusiness

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.

Reject Fluid Simulations, Return To Rheoscopic Fluid

August 25, 2026 0

Fluid simulations are one of the “killer apps” of high-performance computing, but if you can’t afford the performance, they can take a depressingly long time to run. Depending on your use case, as long as you keep the Reynold’s number in mind– or are just looking for a qualitative look at pretty flows–you might be able to get away with purely-practical simulations using rheoscopic fluid, as [Visual Thinker] demonstrates in a recent video.

The fluid, as you can guess from the name, lets you scope out rheos— that’s flow, for those of you didn’t take Greek. Making it is as simple as you could ask for: get some mica flakes, which are readily available to add ‘sparkle’ to cosmetics, and mix with water and a drop of soap. The soap isn’t always necessary, but depending on your mica it helps keep it in suspension and avoid clumping– [Visual Thinker] found it helped him a good deal. Being flat plates of reflective material, the mica flakes catch the light and sparkle beautifully– and since they align with the fluid shear, they show you exactly what’s going on in your ‘simulation’.

[Visual Thinker] isn’t starting with serious simulations; the first thing he tries is essentially a toy that lets him see fluid flow around a Benchy by sticking magnets in it and using it to move a cross-section of its hull though a thin layer of fluid sandwitched betwixt pieces of laser-cut acrylic. We don’t call it a toy to disparage it, though– we totally want one. [Visual] mentions the idea of a coffee table combining the concept with the kind of underslung mechanism we see in sand drawing tables, which sounds dangerously hypnotic. If any of you build one, please try and tear your eyes away long enough to let us know.

He has another beautiful piece that make the video worth watching: a wind-tunnel, again made of laser-cut acrylic and printed parts. With careful consideration of the scale and flow speeds, that one might actually prove useful– and even if it doesn’t, it’s pretty enough that it doesn’t really matter. Beauty has its own utility sometimes.

Most wind tunnels we see around here use actual wind, but rheoscopic fluid was invented for this sort of thing, even if it does make for pretty baubles.


Native SMB3 Client Brings Modern NAS Access To 20-Year-Old PowerPC Macs

Native SMB3 Client Brings Modern NAS Access To 20-Year-Old PowerPC Macs

As software updates cease for operating systems, they eventually begin to lose access to parts of the LAN and internet due to out of date encryption features, as well as the inability to handle file sharing protocols like SBM3, which is somewhat of a necessity if you have e.g. a NAS on the LAN. Such too was the case with [watermark_hd]’s 20-year old PowerPC Macs and their installations of OS X Tiger and Leopard.

Cue Aqualink, a native SMB3 client for these older OS X versions that uses [Ronnie Sahlberg]’s libsmb2 server/client library for SMB2 and SBM3. The source code can be found over on GitHub, along with a Japanese translation. By using a local WebDAV server Tiger’s built-in mount_webdav feature can be used to mount these remote volumes.

While you can often still use SMB1 even on modern Windows and Linux/BSD via Samba, allowing even retro systems like these PowerMacs to speak SMB3 is at least a great boost for network security, even if the aforementioned encryption shortcomings mean that you cannot quite run encrypted file shares yet.

Although OS X eventually began to adopt modern SMB versions, some of us may remember how incredibly buggy they were, to the point that us OS X users often had to fall back to CIFS (SMB 1.0), so this is another potential use for this Aqualink application.


AI Book Scanning: Just What Is A Rare Book?

AI Book Scanning: Just What Is A Rare Book?

One of the stories of the last few weeks has been that AI companies have been scanning books in very large numbers in order to train their models with content guaranteed to have been written before 2002, and thus AI free. It’s caused some outrage, because of the size of the operation, and because the scanning process is destructive. In particular the phrase being bandied around is that these are rare books, and it’s this phraseology I find problematic. I think it’s time to unpack why that is the case.

It’s Not Book Burning, Folks

Before I worked for Hackaday I had a long career in and around the publishing industry, mostly on the electronic side, but from time to time crossing paths with my colleagues in the world of paper-based publishing. I understand the appeal of a good book, I’ve spend a lot of my life among bibliophiles, and let’s just say I own a few books myself. In particular I understand the symbolism of destroying books, bringing to mind as it does the actions of repressive regimes. I have stood in Bebelplatz in Berlin where the photo of Nazi student organisation members burning the library of Magnus Hirschfeld’s institute was taken in 1933, and if you know me, you’ll have an idea why that’s close to home. But for all that, what the AI companies are doing is not the same thing.

In this case they’re destroying the books for two reasons. Firstly, as I remember from a previous employer in the publishing world, it’s much easier to digitise a stack of papers than it is a bound book. Thus I’m pretty sure that’s one reason they remove the binding before digitising the pages. Then secondly, as I understand it it’s a copyright issue. If they buy a book, digitise it, and destroy the physical copy, they can legitimately claim that only one copy of it exists, and they hope, sidestep copyright claims from publishers.

When Rare Maybe Isn’t Really Rare At All

You’ll only see one of these numbers on a book published since 1970.

Perhaps the most pertinent question then is just what are the books being scanned and destroyed? They’re almost universally described as “rare”, but is that accurate or sensationalist? It brings to mind a dusty library filled with priceless tomes hand-transcribed by monks which it would be a crime to destroy, but there’s something that explodes that vision in an instant.

If you read the reports of what’s happening, they are ordering books by ISBN number. That’s an international system for identifying books, which was only introduced in 1970. If they’re ordering a book by its ISBN, it’s no medieval illuminated manuscript.

So the books being scanned and destroyed are relatively new, but can they still be described as rare? In that case just like anything else mass-produced since 1970, how many survive depends on the size of the original print run and how valued they have been since. So a few of these books can be physically rare in the sense of being uncommon, but if they are next-to-valueless, it’s fairly obvious nobody has particularly cared about their survival up to now. It’s likely that any books printed since 1970 which are both rare and of value will have their future assured, so the AI industry is not committing the wanton destruction of culture the reports would like to suggest.

You Need To Know Just How Many Books Get Pulped Every Year

I’m left feeling that a combination of the symbolism of destroying books along with a distaste for AI companies has inflated the status of these books well beyond their worth. If people truly had a care for old books they would be shocked to know how many are pulped each year by the paper recycling industry.

The publishing industry has been churning out mass-produced books for centuries now, so the world is awash with old books. Where do these newly-minted bibliophiles imagine they all go, to the Great Library In The Sky? I haven’t even touched yet upon the publishing industry, which pulps vast quantities of brand new unsold books every year. Where is the outrage, I ask?

We all love to dunk on AI companies, and Heaven knows, there are plenty of reasons to do so. Among all those reasons, sadly destructively digitising books is pretty low on the list. Please, ask the other questions, the ones they really don’t want to answer!
