Trying to Fix a Suspiciously Cheap Enterprise-Grade Network Switch
When you see a listing for an Ethernet switch whose specification list is in effect โyesโ, with a four-digit price tag when new, and with the seller asking for less than 10% of said $3,000 asking price in an โuntestedโ condition, the only rational thing to do is of course to mash that โbuyโ button. This is what [This Does Not Compute] did, and created a video about to show what a great investment decision this was.
Naturally this Juniper EX4100-F-12P switch came without power supply brick for its 48VDC input. Figuring out its pin-out and probing said input showed that the voltage rails had been shorted, giving a first clue as to why this switch had been on sale for so very cheap. Bravely hoping that it would be a straightforward fix, the unit was disassembled.
With a 280 Watt power brick, itโs little wonder that the top of the unit is a one massive aluminium heatsink, including a large heatpipe. Also visible on the lid near the power input was a very-bad-news black skid mark.
From that first discovery the news just got worse and worse, with clear signs of water ingression, rust and corrosion, along with the aftermath of a powered circuit meeting such bad corrosion. After some clean-up itโs clear that some components had violently exploded, ripping apart layers of the PCB and likely parts of traces in those inner sections too.
With no schematics available and no other good repair options via Juniper or anywhere else, it seems that unfortunately this gamble turned out to be merely a pile of e-waste and a few bucks worth of scrap metal. Caveat emptor, once more.

Making a Neo Nuvistor Project in 2026
For a little while vacuum tubes and semiconductors were fighting a heated battle for dominance, with bipolar junction transistors and 1959โs RCA Nuvistor both allowing you to build a compact circuit with relatively low power usage and no high voltages. Although we now know that semiconductor technology won out overwhelmingly, that doesnโt mean that you cannot build a brand new Nuvistor board in 2026, as [Eric Schlaepfer] AKA [TubeTimeUS] recently did.
Nuvistors saw their most use in small-signal radio frequency applications, like VHF and UHF, with excellent low-noise characteristics that saw them used until the early 1970s in television sets, radios and oscilloscopes, as well as in space probes like the 1960s US Ranger Moon missions, so by that metric they had a good run.
Nothing so exciting is built in this video, sadly, but alongside a breakdown on how nuvistors work, we do see a discrete 555-style timer built using a gaggle of tetrode nuvistors, giving a pretty good idea of what using them in a project is like. Being a vacuum tube at its core, nuvistors still have the heater element, which is what gives vacuum tubes their reputation for being slow to start working and large current draw.
Despite their drawbacks, nuvistors still have a range of benefits compared to modern-day transistors, including being practically immune to electrostatic discharge (ESD) and electromagnetic interference (EMI) all the way up an EMP that will destroy most semiconductor electronics.
That said, the somewhat limited 8-nuvistor implementation of the 555 had to get a few extra pins for the heater supply, which burns up about 7.5 Watt just to allow the circuit to function. Terming it the โhollow-state 555 timerโ, it works effectively just like any semiconductor 555, just with that extra power cost and of course no significant prospect of making it smaller, barring a semiconductor evolution as with the pixels-sized CRTs in the SED and FED type displays.
We covered the nuvistor before, including a great reference on this device, and its history that was much longer than people often assume today, as well as the vacuum tubes we use every day in for example our microwaves.
This Machine Makes 35mm (Almost) Film
The revival in film photography has brought a range of specialist films to tempt the experimenter, as well as increased the popularity of loading your own cartridges. But perforating the film from blank stock has always been beyond the reach of home gamers. Now [Jon Schiereck] has done it, but not quite with film. Heโs made a perforator for photographic paper, producing a strip which can be shot in a camera. Itโs film, but itโs not exactly film.
The machine takes the form of a 3D printed mechanism which feeds a strip of photographic paper through a pair of punches to make the sprocket holes. In this case those holes are circular, being made by a pair of drill bits ground for the purpose, and theyโre moved up and down by a crank driven by a set of gears from a hand crank or even a cordless drill. A rubber roller pulls the film forward.
It seems to be a well-thought-out machine, and you can try it yourself for free via a slightly unusual distribution medium, his Ko-Fi page. In case youโre worried about finding a slitter to make those 35mm paper strips, it seems heโs also working on a 3D printable one of those. So you can shoot on paper, and develop it just as you would a print.
If youโre further into extending what you can film through the use of a 3D printer, how about 8 mm movie film?

This Circuit Sculpture is an ESP32-Powered Console
Expressif might not have intended the ESP32-S3 to become an emulation powerhouse, but thatโs certainly what has happened. The little microcontroller seems perfect for recreating the Game Boys or Game Gears of years past, and there are a lot of software options to that end. Having grabbed firmware off a github repo, you still need a physical build to hold, and thatโs where this one by [HVT Lab and Huy Vector] stands out.
As you can see, theyโre letting everything hang out โ not even in a 90s-inspired clear case, but with an open frame of soldered brass, with just a small strip of 2 mm clear acrylic to help stabilize the buttons. That appears to be held with cyanoacrylate glue, but itโs brass and solder doing the majority of the structural work here. We might be a little more confident tossing this lovely device in a bag or pocket if the whole device was boxed in with that acrylic โ shorting the exposed power bus on your keys sounds like a bummer โ but we canโt argue with the aesthetic vision here. Itโs a lovely build on the physical end.
From the video it looks like the software is based on Retro-Go, which weโve seen in use before. In any case, there are plenty of open source projects you could load onto the ESP32-S3 powering this circuit sculpture, though, from NES to IBM PC.

The Big F Awards Celebrates Culinary and Hospitality Excellence at its 13th Edition
A rigorous, independent evaluation process continues to define the credibility of The Big F Awards

New Delhi, 10th September: The 13th edition of The Big F Awards concluded at The Westin, Gurgaon, bringing together accomplished professionals, emerging talent and enterprising brands from across Indiaโs culinary and hospitality landscape. More than a celebration of achievement, this yearโs edition reaffirmed the platformโs core principle: recognition must be earned through a credible and rigorous evaluation process.
At the heart of The Big F Awards is a jury-led approach designed to place merit ahead of visibility, reputation or commercial scale. The awards follow a structured and independent evaluation process, with entries assessed through successive rounds of screening and scoring against defined parameters including originality, execution, consistency, quality and sectoral relevance. The framework is designed to ensure that every participant is assessed on the strength of their work, rather than their profile, popularity or market presence.

The jury for the 13th edition comprised Chef Nita Mehta, Chef Kunal Kapur, Chef Ashish Bhasin, Chef Sabyasachi Gorai, Pawan Soni, Diwan Gautam Anand, Sameer Bawa, Khurafati Nitin, Rocky Singh and Anirudh Singhal. Bringing together experience across cuisine, hospitality, media and business, the panel applied a common evaluation framework to assess the nominees and arrive at the final results.
Importantly, the process is built to create a level playing field. Commercial size, public visibility and geographical location do not determine recognition. The platform actively seeks to bring deserving work into consideration, including independent ventures, emerging professionals, newer businesses and establishments that may not always receive the same visibility as larger or more established names.

The awards also maintain a clear separation between participation and recognition. There are no nomination fees and no pay-to-participate mechanisms, reinforcing the principle that an award should be a result of merit rather than commercial participation. Winners are not disclosed in advance, with the final results remaining confidential until they are announced at the awards ceremony.
Speaking after the ceremony, Pawan Soni, Host & Jury member, The Big F Awards, said, โThirteen editions have reinforced our belief that credibility cannot be created through a trophy or an announcement; it comes from the process behind it. This year, in the 6-month long process the jury evaluated nominations with the same discipline across categories, looking closely at the work, its consistency, execution and relevance. What stood out was the diversity of talentโfrom established names to smaller ventures and professionals receiving national recognition for the first time. That is precisely what we want The Big F Awards to stand for: a platform where deserving work has an opportunity to be recognised on merit, irrespective of visibility or scale.โ
The 13th edition saw participation from independent ventures, established organisations, chefs, restaurateurs and emerging businesses across multiple regions and formats. The broad participation model reflects the awardsโ continued effort to identify and recognise excellence beyond conventional industry circles.

The recipients included Megu, who won League of Legends Awards, followed by Nisaba in the Noteworthy Newcomer category. Inja received the Restaurant of the Year distinction, while Best Cocktail Bar, Cocktail Menu of the year and Best Debut Bar were presented to AaBbCc.concept. Further honours went to Porus Arora for Restaurateur of the Year and Sahil Sambhi for Nightlife Entrepreneur of the Year.

Highlights from the evening included Chef Manish Mehrotra, Chef Harpal Singh Sokhi, Rocky Singh, Rocky Mohan, Chef Manisha Bhasin, Zorawar Kalra, Sid Jalan amongst other dignitaries attending the presentation ceremony.
As The Big F Awards closes its 13th edition, its focus remains unchanged: to build recognition around work that stands up to scrutiny. The platform will continue to expand its outreach for the next edition, bringing a wider pool of professionals, establishments and businesses into a process where credibility, consistency and merit remain at the centre of recognition.

Reverse Engineering The Philips PM5139
The Philips PM5139 is not famous. It won no great victories on the battlefield, nor was instrumental in changing the political landscape. It was just a useful function generator that you might find on a workbench somewhere, doing its job quietly and relatively accurately. [doctormord] has been doing the work to reverse engineer this humble piece of hardware.
The PM5139 is poorly documented; the only existing service manual out there is for the PM5138A, a less-capable sister model. Hence, there was some value in reverse engineering the device to understand it better. Work started with two EPROM dumps capturing what Philips put in the box all the way back in the early 1990s. From there, the code was examined and tinkered with until [doctormord] felt confident to modify it and improve upon what was already there. This was achieved with the aid of an 8051 emulator that could run the code to make it obvious what was going on. The result was a custom โV2.0โ firmware that adds six arbitrary waveforms to the function generator and the ability to play simple music, amongst other tweaks.
We love to see old hardware given new functionality, even decades down the line, and we love some good reverse engineering, too. Video after the break.

- Tech Moves: T-Mobile appoints CFO; Microsoft and Blue Origin VPs depart; AZX and Caddi name leaders
Tech Moves: T-Mobile appoints CFO; Microsoft and Blue Origin VPs depart; AZX and Caddi name leaders

โ Telecom giant T-Mobile announced that Jessica Uhl will join as chief financial officer-designate later this month, and succeed Peter Osvaldik as CFO in February. Uhl served as CFO of Shell and worked for the global oil and energy giant for more than 17 years. She joins T-Mobile from GE Vernova, where she was president.
โI am thrilled to welcome Jessica to T-Mobile,โ Srini Gopalan, president and CEO of T-Mobile said in a statement. โShe brings deep financial and strategic acumen, capital allocation expertise and an innovative growth mindset that is a perfect fit for T-Mobileโs next era.โ
Osvaldik will transition to strategic advisor and retire from T-Mobile in July. He joined the company in 2016 and became chief financial officer in 2020. Osvaldikโs tenure โhas been defined by disciplined financial stewardship, consistent financial outperformance, and an unwavering commitment to T-Mobileโs mission,โ the company said.
The move marks the latest leadership shakeup at the Bellevue, Wash.-based company. Mike Katz, T-Mobileโs chief business and product officer, announced his departure in July, and Chris Sambar was named chief enterprise officer. T-Mobile has cut 470 jobs in its home state this year and closed numerous retail locations.

โ Brent Colburn, Microsoftโs vice president of global public affairs, is resigning after three years, effective mid-October.
โStepping away from Microsoft is not a decision that I made lightly, but ultimately it is the right one for me and my family,โ said Colburn, who has been commuting weekly between his home in Oakland, Calif., and Microsoftโs Redmond, Wash., headquarters.
Colburnโs career has spanned leadership roles in government, academia and philanthropy. That includes serving as principal advisor to the secretary of defense for communications and chief of staff to then-Secretary Shaun Donovan. More recent roles include communications vice president for the University of California in Oakland, Princeton University and the Chan Zuckerberg Initiative.

โ After nearly 13 years, Audrey Powers has left Blue Origin, the aerospace company founded by Jeff Bezos that develops reusable rockets, spacecraft and rocket engines. She was on Blue Originโs October 2021 spaceflight that also carried โStar Trekโ star William Shatner and two others.
โHopefully, Iโve helped change peoplesโ impressions of rockets (they land, too), astronauts (they are everyone), and our Earth,โ Powers said, adding that she was sad to leave, but grateful that she took a chance on โa little startup no one had heard of.โ
Powers held the title of deputy and vice president of the New Shepard Business Unit, which is the program that carries people and research payloads into suborbital space. She is an attorney who has previously worked at NASA as a flight controller and as a senior systems engineer at Lockheed Martin.

โ Michael Levi has joined AZX as chief commercial officer of the Bellevue-based startup, which works with utilities and other industries to build in-house AI technologies supporting their missions.
Levi is based in San Francisco and was previously vice president of marketing and growth for KloudGin, where he helped reposition the companyโs field service software into an AI-native platform for utilities and the public sector. He earlier founded L1CG, a go-to-market advisory, and has held leadership roles in energy, renewables, supply chain and fintech.

โ Jason Alafgani was named head of marketing for Caddi, a Seattle startup that launched out of AI2 Incubator and is automating basic business operations with generative AI. Alafgani is the co-founder of startups including the podcast company Jellypod and worked as marketing leader for Appwrite, Dodgeball, Mode and others.
โ Dr. Amir Iravani has joined Los Angeles-based UCLA Health as director of the theranostics program, which focuses on treating cancer using targeted radiation therapy. Iravani previously served as theranostics clinical director at Fred Hutchinson Cancer Center in Seattle and was an associate professor of radiology at the University of Washington School of Medicine.

โ Portland Metro Region Innovation Hub has hired Kelly Lyons as director of the organization, which provides networking, coaching, funding and other support to entrepreneurs. Lyons is the founder of two startups and has served in leadership at Core Education, Umpqua Bank and Development House, a social services nonprofit.
โ DigiStor, a Vancouver, Wash.-based provider of secure data-at-rest protection solutions, appointed Michael Callahan to its board of directors. Callahan co-founded Awake Security and PolyServe, which was acquired by HP.
