Nobody Can Complain When You Fart, If It’s For Science!

February 15, 2026 by 8 Comments

There are some stories that you can tell a writer has enjoyed composing, and, likely, whoever wrote the piece for Medical Express reporting on new smart underwear to measure human flatulence was in their element. It follows a University of Maryland project to create a clip-on hydrogen sensor that can be attached to a set of underwear to monitor gaseous emissions.

Lest you think that this research has a non-serious tone to it, it seems that gastroenterologists have incomplete data on what constitutes normal activity. The aim of this research is to monitor a large number of people to create a human flatus atlas that will inform researchers for years to come. Better still, they’re recruiting, so if you’re a regular Johnny Fartpants who misspent their youth lighting farts while drunk and would like to atone, get in touch.

We know that gut problems can be no fun at all, so fart jokes aside, if this research makes advancements in their study, it can only be a good thing. Meanwhile, if you are one of those superproducers they mention, perhaps you need to build the FartMaster 3000.

MyMiniFactory Has Acquired Thingiverse Bringing Anti-AI Focus

February 13, 2026 by 37 Comments

One of the best parts of 3D printing is that you can freely download the plans for countless models from sites like Thingiverse, Printables, and others. Yet with the veritable flood of models on these sites you also want to have some level of quality. Here recent news pertaining to Thingiverse is probably rather joyful, as with the acquisition of Thingiverse by MyMiniFactory, it should remain one of the most friendly sites for sharing 3D printing models.

Although Thingiverse as a concept probably doesn’t need much introduction, it’s important here to acknowledge the tumultuous times that it has gone through since its launch in 2008 as part of MakerBot. Both were acquired by Stratasys in 2013, and this has led to ups and downs in the relationship with Thingiverse’s user base.

MyMiniFactory was launched in 2013 as a similar kind of 3D printing object-sharing platform as Thingiverse, while also offering crowdsourcing and paid model options. In the MyMiniFactory blog post it’s stated that these features will not be added to Thingiverse, and that nothing should change for Thingiverse users in this regard.

What does change is its joining of the ‘SoulCrafted‘ initiative, which is an initiative against machine-generated content, including so-called ‘AI slop’. There will be a live Q & A on February 17th during which the community can pitch their questions and ideas, along with a dedicated Thingiverse group.

CIA’s World Factbook Is Gone

February 6, 2026 by 15 Comments

Before the Internet, there was a certain value to knowing how to find out about things. Reference librarians could help you locate specialized data like the Thomas Register, the EE and IC Masters for electronics, or even an encyclopedia or CRC handbook. But if you wanted up-to-date info on any country of the world, you’d often turn to the CIA. The originally classified document was what the CIA knew about every country in the world. Well, at least what they’d admit to knowing, anyway. But now, the Factbook is gone.

The publication started in 1962 as the classified “The National Basic Intelligence Factbook,” it went public in 1971 and became “The World Factbook” in the 1980s. While it is gone, you can rewind it, including a snapshot taken just before it went dark on Archive.org.

Restoring The Soul Of A 1940s Radio

February 4, 2026 by 13 Comments

Although we do often see projects that take antiques and replace some or all of their components with modern equipment, we can also sympathize with the view that (when possible and practical) certain antique electronics should be restored rather than gutted. [David] has this inclination for his 1948 GE radio, but there are a few issues with it that prevented a complete, period-correct restoration.

The main (pun intended) issue at the start of this project was safety. The original radio had a chassis that was just as likely as not to become energized, with the only protection being the plastic housing. [David] set up an isolation transformer with a modern polarized power cable to help solve this issue, and then got to work replacing ancient capacitors. With a few other minor issues squared away this is all it took to get the radio working to receive AM radio, and he also was able to make a small modification to allow the radio to accept audio via a 3.5mm jack as well.

However, [David] also has the view that a period-correct AM transmission should accompany this radio as well and set about with the second bit of this project. It’s an adaptation of a project called FieldStation42 originally meant to replicate the experience of cable TV, but [Shane], the project’s creator, helped [David] get it set up for audio as well. A notable feature of this system is that when the user tunes away from one station, it isn’t simply paused, but instead allowed to continue playing as if real time is passing in the simulated radio world.

Although there are a few modern conveniences here for safety and for period-correct immersion, we think this project really hits the nail on the head for preserving everything possible while not rolling the dice with 40s-era safety standards. There’s also a GitHub page with some more info that [David] hopes to add to in the near future. This restoration of a radio only one year newer has a similar feel, and there are also guides for a more broad category of radio restorations as well.

How Vibe Coding Is Killing Open Source

February 2, 2026 by 130 Comments

Does vibe coding risk destroying the Open Source ecosystem? According to a pre-print paper by a number of high-profile researchers, this might indeed be the case based on observed patterns and some modelling. Their warnings mostly center around the way that user interaction is pulled away from OSS projects, while also making starting a new OSS project significantly harder.

“Vibe coding” here is defined as software development that is assisted by an LLM-backed chatbot, where the developer asks the chatbot to effectively write the code for them. Arguably this turns the developer into more of a customer/client of the chatbot, with no requirement for the former to understand what the latter’s code does, just that what is generated does the thing that the chatbot was asked to create.

This also removes the typical more organic selection process of libraries and tooling, replacing it with whatever was most prevalent in the LLM’s training data. Even for popular projects visits to their website decrease as downloads and documentation are replaced by LLM chatbot interactions, reducing the possibility of promoting commercial plans, sponsorships, and community forums. Much of this is also reflected in the plummet in usage of community forums like Stack Overflow.

Espressif Introduces The ESP32-E22 Wi-Fi 6E And Bluetooth Co-Processor

January 21, 2026 by 24 Comments

Espressif has unveiled its latest major chip in the form of the ESP32-E22. Officially referred to as a Radio Co-Processor (RCP), it’s intended to be used via its PCIe 2.1 or SDIO 3.0 host interface to provide wireless communications to an SoC or similar.

This wireless functionality includes full WiFi 6E functionality across all three bands, 160 MHz channel bandwidth and 2×2 MU-MIMO, making it quite a leap from the basic WiFi provided by e.g. the ESP32-S* and -C* series. There is also Bluetooth Classic and BLE 5.4 support, which is a relief for those who were missing Bluetooth Classic in all but the original ESP32 for e.g. A2DP sinks and sources.

The ESP32-E22 processing grunt is provided by two proprietary Espressif RISC-V CPU cores that can run at 500 MHz. At this point no details appear to be available about whether a low-power core is also present, nor any additional peripherals. Since the graphics on the Espressif PR article appear to be generic, machine-generated images – that switch the chip’s appearance from a BGA to an LQFP package at random – there’s little more that we can gather from there either.

Currently Espressif is making engineering samples available to interested parties after presumed vetting, which would indicate that any kind of public release will still be a while off. Whether this chip would make for an interesting stand-alone MCU or SoC along the lines of the -S3 or -P4 will remain a bit of a mystery for a bit longer.

Thanks to [Rogan] for the tip.

Washington State Bill Seeks To Add Firearms Detection To 3D Printers

January 19, 2026 by 181 Comments

Washington State’s House Bill 2321 is currently causing a bit of an uproar, as it seeks to add blocking technologies to 3D printers, in order to prevent them from printing “a firearm or illegal firearm parts”, as per the full text. Sponsored by a sizeable number of House members, it’s currently in committee, so the likelihood of it being put to a floor vote in the House is still remote, never mind it passing the Senate. Regardless, it is another chapter in the story of homemade firearms, which increasingly focuses on private 3D printers.

Also called ‘ghost guns‘ in the US, these can be assembled from spare parts, from kits, from home-made components, or a combination of these. While the most important parts of a firearm, like the barrel, have to be made out of something like metal, the rest can feature significant amounts of plastic parts, though the exact amount varies wildly among current 3D-printed weapons.

Since legally the receiver and frame are considered to be ‘firearms’, these are the focus of this proposed bill, which covers both additive and subtractive technology. The proposal is that a special firearms detection algorithm has to give the okay for the design files to be passed on to the machine.
