SmallRun.net Enters The Marketplace Market

June 21, 2026 by Tyler August 19 Comments

So you have a project that you love, and everyone else loves too. People start saying “you should sell this” but where? Well, there’s a new marketplace you might want to consider called SmallRun, aiming at makers and their, well, small production runs.

SmallRun will absolutely host your custom PCBs, on-demand 3D prints, and other traditional maker products — but they’ll also happily sell your merch, too. Along with electronics and hardware, they aim to allow you to sell products in categories like tabletop gaming, sciences, and yes, accessories/apparel.

For sellers, they offer automatic payouts and promise to take care of the taxes by integrating with Stripe. That said, they’re still working on getting the whole VAT thing set up for products imported to the EU. EU to EU sales are apparently OK. They’ll host build logs, which may drive engagement with your product. There’s even a handy tool to import your existing listings from eBay, Tindie, Lectronz, Etsy, Shopify, or Crowd Supply if you’re already in the biz. They make their money by taking a cut of your sales: ̶e̶i̶g̶h̶t̶ now reduced to seven percent, plus forty cents per listing.

Depending on your perspective, you might wonder if we need another marketplace, To that we can only say: “Let a thousand flowers bloom!” Competition should drive these marketplaces to continuously improve and we all win.

If you’re selling online, even packaging can become a project. If you’re not, but are interested in starting, our “From Project to Kit” series from ten years back remains surprisingly relevant.

Thanks to [Aron] for the tip!

Blender 5.2: Coming Soon With Improved Simulations

June 21, 2026 by Tyler August 8 Comments

Traditionally, one of the weak points in Blender has been simulations, with even professional users of the free and open source computer graphics suite off-loading such tasks to programs like Houdini. But according to [3Dan], once version 5.2 is out of beta in July, that may become a thing of the past.

Simulations aren’t a necessary part of a 3D animation software, but they are very, very nice to have. If you want realistic-looking fluids, hair, or cloth, it’s incredibly difficult to animate it by hand. One, because there are so many degrees of freedom in, say, flapping cloth, keyframing is a major pain, but also figuring out how to make the model move and deform realistically is by no means trivial. It’s easier to offload all that on a physics simulation; then, as long as the physics is realistic, the animations will be as well.

That’s not easy, computationally speaking, and one thing that’s clear is there’s been work behind the scenes to optimize the simulation algorithms, not just improve the workflow, as the basic “drop cloth on a monkey head” demo now runs twice as fast. The new workflow itself bring simulations more into line with how Blender has been going– it’s part of geometry nodes now. So there’s simulation nodes you bring in, but that means things like tearing cloth become quite straightforward compared to the occasionally byzantine workarounds required before. This node-based workflow also brings Blender more into line with how paid software works these days.

[Dan] demonstrates the power of it by adding air pressure to a cloth simulation with some custom nodes, inflating and popping a fabric sphere. He also demonstrates how cloth simulation can be applied to animate realistic foliage. This update probably doesn’t have Houdini developer SideFX shaking in their boots, but it might allow some animators to stop paying that license and go fully-open source, which is great to hear.

Even if you’re not into digital sculpting or animating, you may find yourself downloading a copy of Blender at some point to add texture to 3D prints, or make fancy resin-print miniature models FEM-friendly. The right addon can even let Blender do parametric CAD, though FreeCAD is getting better all the time, too.

Bernoulli Disk Goes “Wii!” When Plugged Into WiiU

June 20, 2026 by Tyler August 10 Comments

The Bernoulli disk was a wild piece of 1980s hardware. Take a big floppy. Spin the platter at 1500 RPM just a micron or so from a read head. The airflow around that rapidly-spinning disk actually stabilizes the disk that close to the read-head via the Bernoulli effect, hence the name. Once upon a time, everybody wanted a Bernoulli Box to put under their Macintosh 512, but [Will It Work?] wanted to see how well these old drives held up to the 21st century by using it to load games onto a WiiU.

It’s not as crazy at is it seems. The WiiU is happy to read and write anything that looks like a USB mass storage device. The Bernoulli Box is of course pre-USB — even the later model 5 1/4″ drive [Will] is using from 1987. That means it uses SCSI, the USB of the 1980s. He’s got a 90 MB disk, though Iomega did make disks of higher capacity in that format, all the way up to 230 MB. Yes, the same Iomega of Zip-drive fame and infamy. But don’t worry, the peculiar pneumatic nature of the Bernoulli disks makes them immune to the click of death.

You might think it’s going to take a great deal of hacking and homebrew to get the WiiU talking to a SCSI drive from the 80s, but as we said in the introduction, Nintendo made this thing respect USB conventions, so all that’s needed is an SCSI-to-USB cable. Well, plus a passive SCSI 1 to SCSI 2 adapter to get the USB adapter to fit.

It doesn’t seem like the drive slows down the WiiU nearly as much as we’d expect, but then it’s not a console known for fast load times. The other surprising detail is how much space the WiiU’s formatting sucked up, knocking the 90 MB disk down to only 68 MB. Combine that with the WiiU’s firmware wanting to pad space for save files, and not much fits. Thus we don’t expect this odd tower of power to take off like the original did. Still, if you had one of these back in the day, it might be a nice nostalgia hit to hear the drive whirring away.

If you think a disk drive is something Nintendo would never imagine for their consoles, think again! The Japanese version of the NES had the Famicom Disk System, which turns out to be essential if you want to run UNIX on it.

Come With Me If You Want To Weed: Autonomous Weedinator Robot Back For 2026

June 19, 2026 by Tyler August 18 Comments

The WEEDINATOR agricultural robot is one of the longer-running projects we’ve featured here on Hackaday. We first featured it way back in 2017 for that year’s Hackaday prize, and after a nearly a decade of work on-and-off it has hit a very important milestone: it is now an effective horticultural instrument, as you can see in the latest demo video below.

There have been some big changes over the years. For one, the scope of the project narrowed considerably with the adoption of a commercial tractor as the base, specifically an Iseki 321 . They picked the Iseki after examining several competitors, and it won out because its hydrostatic drive was best able to handle the very low speeds desired. It looks like they’re now focused on cultivation — that is, tearing out weeds mechanically — rather than the flame weeder they started with. The cultivators are of the claw type, and has three claws powered via the tractor’s hydraulics for control in all three axis: X, Y and Z. Of course the project now leverages modern computer vision toolsets, using a combination of OpenCV and YOLO26n running on a Jetson Nano board. The robotics half of the equation is handled on an STM32 Nucleo.

Aside from being one of our longer-running submissions, we have to call out the team for being one of the very few — perhaps the only — to go to the effort of creating a theme song for their project. If you’ve only got a minute to see the robot run, you might as well look at the second video embedded below and give a listen.

While WEEDINATOR has got the most persistence, they’re not the only ones in the garden robot game. We’ve seen projects using everything from concentrated sunlight to precision-applied herbicides to clear unwanted plants over the years.

Commodore Unveils Linux Powered Flip Phone

June 18, 2026 by Tyler August 74 Comments

Whatever happens with the new incarnation of the Commodore corporation, we’ll always remember the old one fondly. Well, we’ll remember certain of its products fondly, at any rate, if not the corporate leadership that drove them under. About that, perhaps the less said the better. That’s why we’re looking at the revived Commodore’s latest offering with equal parts interest and trepidation — is there really a market for a Linux-based, Commodore branded flip phone in 2026 and beyond?

The official reveal trailer, which you can watch below, can only be described as weaponized nostalgia for the late 90s, which tracks because the revived C-64 is more-or-less the same thing for the 8-bit era. That said, between replaceable batteries, actually having a decent camera — a 48MP Sony module — quality Cirrus Logic DAC for audio, and running the Linux-based, Android-app-compatible Sailfish OS, the “Callback 8020” ticks all the boxes. Except for price, that is. Many will find the $499 USD launch price a little tough to swallow in this economy, so we hope they aren’t betting the farm on this one being a mass hit.

Still, compared to other premium “digital minimalist” products like the LightPhone III, the price looks reasonable — and with web browsing and social media explicitly excluded from the app store, this phone is firmly in that category. At least this one comes with some sweet Commodore branded headphones, which double as an FM antenna just like they did on your Nokia back when.

While it doesn’t come with DOOM from the factory, it does come with Snake and a selection of emulated C64 games . Ringtones are SID samples, but of course there’s no actual SID chip in the phone, any more than there’s a 6502. That said, if someone builds a phone around a 6502, please let us know.

No, it’s not a new Amiga, as so many of us were hoping for, but by putting quality modern components into the flip phone form-factor, at least they’re trying to innovate (or perhaps retrovate) and we have to respect that. Only time will tell if the market does.

Leaky Player Piano Gets MIDI Upgrade In YouTube Restomod

June 17, 2026 by Tyler August 5 Comments

The word “restomod” is a bit nebulous, but it’s normally used in the automotive world to describe taking an old car and making it better-than-new with all the technological improvements the original builders would have used, had they been available. We think the word applies to [Alnwlsn]’s MIDI-actuated player piano, because what are those punched rolls of paper, but the MIDI of the 19th century?

Unlike a lot of automotive restomods though, this one is mostly reversible. He did drill few holes and slots in the original wood, but nowhere that it would alter the integrity or original operation of the player piano mechanism. The MIDI-controlled solenoids just poke the same key paddles from below that the pneumatic mechanism used. From the listener or operator’s perspective, unless the doors that reveal the music scroll or lack thereof are open, the piano behaves exactly the same. Except now it has access to the whole wide array of tracks that exist in MIDI form, rather than a paltry selection of hard-to-find piano rolls.

Each of the relays is driven by a MOSFET via shift registers to get 88 outputs out of the single Pi Pico in charge, with a level shifter involved to get the RP2040 speaking 5 V logic. If you’re wondering how that gets volume control, no, the piano isn’t smacking keys at full volume all the time. He’s using the RP2040’s powerful PIO to create a sort of PWM signal to soften the solenoid blows when needed. To save his power supply, he’s also got it set up to stagger the pulses, so multiple relays aren’t pulsed at the same time when the MIDI file calls for chords.

There was actually more overlap between player pianos and MIDI than you might think, given this presentation of an Apple ][ being used to create the piano rolls.

2026 Frikkin Lasers Contest: Steampunk, 360 O-Scope Does It With Tubes

June 17, 2026 by Tyler August 10 Comments

Audiophiles all know everything sounds better fed through vacuum tubes, but did you know visualizers look better with them, too? That’s what we’re forced to conclude looking at the Tachyscope Laser, a 360-degree oscilloscope display that is [Daniel Ross]’s entry into the ongoing Frikkin Lasers contest.

The diagram makes it look easier than building it probably was.

The laser is a good old-fashioned helium–neon tube — something we see less and less of in this era of solid state lasers — and the wavelength gives the waveform display a retro charm. The actual display is unique in our experience, with the beam shining up through a hollow shaft to bounce off a galvanometer mirror on a spinning platform. Galvo sweeps the laser across a translucent target, which creates the waveform by persistence of vision as it spins at 100 RPM or so.

Does the fact that the audio signal feeds through a tube amp to drive the single galvanometer actually improve the visuals? Only in the sense that those tubes make the steampunk-style enclosure look really, really cool, as does the exposed laser tube. That all of the steampunk elements obviously have a point to them rather than just being a another “glue some gears on it” project is icing on the laser-flavored cake.

The contest runs until July 23rd, so there’s lots of time to get laserin’ — and remember that there are categories for DIY lasers and anything that isn’t a display, just in case you think this project puts the bar too high for a light show. We’ve actually featured one of [Daniel]’s tachyscope waveform visualizers before, but that one, madly enough, spun an actual CRT.
