Hackaday Podcast Episode 392: Microscopes, Drones, And Other DIY Things

Hackaday Editors Elliot Williams and Al Williams met to review the week in Hackaday. Turns out, it was a week for tiny things, cybersecurity, nostalgia, and projects that would have been nearly impossible for the average hacker not that long ago. But first, you can hear a little about the upcoming Supercon badge and the trials of importing and exporting parts for the badges.

How many props does your drone have? [Joshua] has one. Want to fabricate semiconductors at home? Do you have a microwave? What about using NFC in your next project? There’s all that and more in this episode.

The quick hacks include a request from NASA for ideas (and, yes, there is prize money) and slide rule tricks, among other things. For the can’t miss articles, the cybersecurity weekly got some appreciation and Al took a trip down memory lane at the Altair 8800 he always wanted.

Check out the links if you want to follow along, and as always, tell us what you think about this episode in the comments, or drop us a line on the mailbag.

The MSX Gets A New Sound Expansion Cartridge

If we’re honest, there aren’t a whole lot of accessories coming out for the MSX computer line this holiday period. There is, however, a new sound expansion cartridge for the diehard fans out there, thanks to [Ricardo Suzuki].

It’s called the Misato MSX, and it’s a cartridge you can build yourself to give your computer a grander set of sound capabilities than it ever had before. At the heart of the cartridge lies the Yamaha YMF288, an OPN3 chip that offered three Software Sound Generator (SSG) channels, six FM channels, and six rhythm channels. Paired with a decent DAC chip, it provides deliciously rich synthesized sound very characteristic of that 1980s/1990s FM synthesis era. The cart can be used for play of a wide variety of OPN music, or creating your own compositions with the right software tools. Audio output can be had either from the stereo line out jack on the cart itself, or mixed down to mono and passed to the MSX’s internal mixer.

If you’ve got an MSX that is a little weedy in its sound capabilities, this cart could be just the thing you’re looking for. We’ve looked at some fun MSX machines before, too. If you’re cooking up your own upgrades for retro machines, don’t hesitate to let us know on the tipsline!

This Week In Security: Record Patch Tuesday, PHP’s Bad Time, The Oldest Vuln, AI Armies, And More

It’s no longer a proper month without Microsoft breaking its own record for security fixes, and October’s Patch Tuesday was no exception. Brian Krebs brings the roundup: more than 1,400 vulnerabilities fixed in a single batch, dwarfing September’s record of nearly 1,000, which itself was about ten times the normal monthly load. According to Tenable, Microsoft has now passed 4,000 CVEs for the year with two months still to go.

Only one of the fixes is for a vulnerability already being exploited in the wild: CVE-2026-96951, a security feature bypass in the Windows Shell affecting Windows 10, 11, and some Server versions. A .NET Framework bypass, CVE-2026-108398, was publicly disclosed before the patch, giving attackers a head start, and with modern AI tooling, it seems like not much of a head start is needed. At least 78 of the bugs are rated critical, and most of those allow remote code execution with little or no user interaction. Windows 10 holdouts can relax a little: Microsoft quietly extended free updates through October 2027.  Given the pace of exploitation, this is probably the only way to prevent an Internet-scale meltdown.

Microsoft credits LLM-driven bug hunting for the volume, which leaves the poor admins who have to test and deploy all of this in an unenviable spot. Fortra’s analysis shows that only 26 Microsoft vulnerabilities have landed in the CISA KEV catalog of actively exploited bugs so far this year, so start there. For the rest, the SANS Internet Storm Center and Cisco Talos have the usual breakdowns by severity. Or, you know, just patch everything and hope for the best, which is roughly what everyone does anyhow.

Rear view of the sand rail whizzing by.

When You Can’t Pick Between Electric And Jet Power, This Buggy Has You Covered

Technically, what [Macona] built with a surplus Solar T-62 turbine is not a dune buggy, but a sand rail, but it does have the delightfully rare combination of electric and turbine drive that is absolutely worth wading through a 53-page forum thread to learn about.

The turbine came bare as surplus, but [Marcona] used a pair of Kia/Hyundai HSG water-cooled motor-generators to turn it back into something very much like the APU it likely started out as. That’s APU as in “Auxiliary Power Unit” in this context, the little generator that keeps the lights on when your plane is sitting on the tarmac. That went into the sort of frame you’d once have put a VW bug engine in — and the 150 HP off the shaft of the turbine beats anything you’ll get with Wolfsburg’s little boxer motor, even after losses in the generator and motors. Even better, the whole assembly, which uses the electric motor from a Mitsubishi Outlander, likely doesn’t weigh any more than the internal combustion engine and transmission, so whatever you call this little off-roader it ought to move well. It certainly seems to in the demo video embedded below.

What it doesn’t do is sip fuel, the T-62 being rated at 19.3 gallons/hr at full load. Fuel efficiency is definitely not the motivation here. He’s absolutely not saving money, especially not with what jet fuel costs these days. It’s one of those projects done purely for the joy of it — where if you have to ask why, you’re barking up the wrong tree. The vehicle isn’t yet street legal, but [Marcona] is working on it.

If you do like the idea of this kind of series hybrid drive, Edison Motors of Canada is working on bringing it both to semitrucks and heavy trucks, and that is motivated by fuel savings. Continue reading “When You Can’t Pick Between Electric And Jet Power, This Buggy Has You Covered” →

DOOM Ported To A $30 Clamp Meter

DOOM. Boil it, mash it, stick it in a stew, it’s the game that runs on anything and everything. Now, the classic shooter is running on a rather unlikely target—a cheap clamp meter of very limited resources, thanks to the work of [Artur Bieniek].

The clamp meter in question is the FNIRSI DMC-100, which can be had for the low price of just $30 or so if you know where to look. It’s a far cry from the many thousands of dollars you’d pay for a heavy old 486-based machine back in 1993. [Artur] got the doomgeneric engine running on the Artery AT32F415 chip that runs the clamp meter.

The chip is pretty capable, with its 150 MHz clock speed, though the 32 KB of RAM posed rather a big limitation to the project. It may be one of the lowest RAM DOOM ports out there. Even with this limit, [Artur] was able to get Episode 1 of Freedoom: Phase 1 loaded on to the thing, including E1M1 to E1M9 along with the title screen, intermissions, the finale, the menu, and four save slots. Color graphics are displayed on the meter’s 320 x 240 screen, and there are even sound effects on the built-in buzzer. Controls are mapped to the rather curious choice of a DJI RC-N1 drone controller.

We’ve seen DOOM running on everything from desk phones to completely custom CPUs. These days you have to try pretty hard to find something it hasn’t already been ported to.

Restoring A Soviet ES-4001 Mainframe Control Panel

Recently the [Chornobyl Family] got their hands on an ES-4001 control panel for a 1970s-era Soviet mainframe, with the intention to restore it to full working order. Not just because they’re really into cool old Soviet technology, but also because of the connection that this control panel holds to the Chernobyl nuclear accident that was so instrumental to the area in modern times.

During the 1970s the USSR felt that it could not be left behind in the race to create better digital computers. This led them to not only create a few original designs, but also effectively clone the IBM System/360 and System/370. This resulted in the ES EVM-series of mainframes, with an ES-1060 finding itself installed at the Duga-1 early warning radar system near what is now the Chornobyl nuclear power plant in Ukraine.

Although the radar arrays are the most well-known feature of the Duga-1, below it is the computer center where the ES-1060 was installed. It was never put into service following the ChNPP Unit-4 accident — all that remains of a once pinnacle of Soviet engineering are the picked-over carcass of the mainframe and its control panel.

The control panel in question was obtained was from the early 1980s, serving a more gentle service life in a datacenter and looks to be in a mostly good condition. That said, there was still enough to be done to make it work and undo the damage of its violent removal from the mainframe. Along the way we also learn how the system was used and how the control panel works.

Although similar in some ways to the System/370, it’s still very different, and with only about 300 of these mainframes produced, it’s worth saving whatever elements still remain today, along with the surviving documentation.

NASA Batteries Survive Extreme Cold And Heat

One of the major limits of mass-produced batteries is the electrolyte. From lead-acid to lithium ion, there’s some temperature where the electrolyte will freeze and cause all sorts of problems, from cracked casings to various non-favorable chemical changes in the battery itself. But if there’ a solid electrolyte available, many of the downsides of charging and discharging batteries in extreme cold disappear. These batteries developed by NASA, for example, can survive some wild temperature swings.

The electrolytes used for these batteries are either a ceramic or polymer electrolyte, both of which are solid. In testing, the batteries could meaningfully operate at temperatures of -60° C and up to 80° C on the high end. Further, the solid electrolyte helps protect them even outside of these temperature ranges. Bringing the battery temperature down to -170° C was not enough to damage the battery at all, and using a small heater to bring the temperature back up to its operating range showed no capacity losses or other issues.

These batteries are eventually intended for use in some of the coldest places outside of Earth still accessible to humans (in theory) such as the south pole of the Moon where the temperatures regularly get that cold and stay cold for long periods, especially in permanently-shadowed craters or places on the Moon we might want to put some telescopes eventually. There are other terrestrial situations where these batteries might be useful as well, since they don’t need as much thermal management as other battery types.
