Glasgow is probably the most useful tool I have access to aside from oscilloscopes and logic analyzers. So versatile and easy to adapt to the problem at hand.

the #GlasgowInterfaceExplorer revD project is up on CrowdSupply! subscribe to get updates and show your interested in the project, we're very excited to bring it to life :D www.crowdsupply.com/fully-automa...

Got DOOM running on my Dji Osmo Nano. Didn't manage to get audio to work though which is a bit sad...

KiCad version 10 is out today! Lots of features, lots of speed. We hope you like it. www.kicad.org/blog/2026/03...

Woop, placed my order. There are a few left. Excited for the BIO 🤘

i built an entire x86 CPU emulator in CSS (no javascript) you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS lyra.horse/x86css/

Very happy to announce the winners of our demoscene competition! 🏆 We had some amazing entries - check out what can be done in just a few square microns of silicon! tinytapeout.com/competitions... Thanks again to our judges and participants! #silicon #demoscene #ASIC

I found the old 35mm slide for the cover for Neuromancer and had it scanned in for your pleasure. Enjoy!

The PicoIDE Crowd Supply campaign is now live! Back the project to be among the first to get yours! PicoIDE is an open IDE/ATAPI drive emulator for retro systems. www.crowdsupply.com/polpotronics...

Motto for this year: do more stuff. I’ll be at FOSDEM if anyone wants to say hi. (Brussels 30/1-1/2)

Did a last minute tapeout because why not 😅 (resubmission/port of an older design). Ahh now I really want to finish some other asic projects I haven’t touched in a while. This winter will be fun.

[coffee nerd talk] I feel a bit like a failure - been dialing in a V60 brew with an 1Zpresso Q grinder and Hario filters but it keeps tasting a bit bitter no matter what I do. Gave up, brewed with a Moccamaster with standard Melitta filters and it tastes amazing. Hnggg. Should I try faster filters?

The wait is finally over, we're happy to announce that the KeebDeck Keyboard and our first product using it, the KeebDeck Basic, are now available for sale from our @lectronz.com store! ⌨️ lectronz.com/stores/solde...

We are hiring! Both technical and admin, please take a look at our jobs page! www.yosyshq.com/jobs #jobs #hire

What happens when one of the main providers that enables #opensource #silicon to thrive...shuts down? Companies like @mith.ro's new wafer.space jump in and offer an even more compelling option. $7K for 1000 chips on the GlobalFoundries GF180MCU process. Learn more: theamphour.com/703-building...

PSA: i now consider grebedoc.dev (and the underlying git-pages server software) feature-complete and production-ready, feel free to use it for all your "not supporting Microsoft-nee-GitHub" needs (or whatever other reasons you might have)!

Disassembling a new iPhone 7 pro Max and using a CNC mill to decap Friggin amazing. youtu.be/7M60g09HB1M?...

Oh hey, STMicro publishing drivers in Rust in the open: github.com/STMicroelect...

Friend: Do you have an FPGA board I could borrow? Me: Let me check… (Hurts a bit that I never did anything cool with the more powerful boards)

Want to help build a crowdsourced microcontroller? You're invited to design peripherals (UARTs, timers, synths, etc.) for a @riscv.org.web.brid.gy chip that will be fabbed for real! Take part for free! tinytapeout.com/competitions...

One of my students sent me the latest quantum factorization record, and I have to admit: I’m shook. eprint.iacr.org/2025/1237

Yes, a file full of zero bits transfers faster over USB2.0 than a file full of one bits. I've known this forever but it still feels ridiculous when you actually test it and it's true! USB truly is cursed.

[Please share with people outside of cybersec] Do you have a horror story when you had to deal with cybersecurity companies / people? This is your chance to vent! → forms.gle/9aX24HrfnEQm... I'm running an anonymous survey to listen to stories and look into the disconnect we sometimes have.

Glasgow is such a great tool for interacting with hardware. Been using it a lot, and it’s both easy and fun to build custom applets for it.

Open source DisplayPort implementations for FPGAs - what's the state of this in 2025? For me, starting out with a single line, at the lowest speed would still be cool. TX is of course interesting, but RX and protocol analyzers would also be interesting.

Does anyone have recommendations for any high quality discussion groups or communities for defensive security? Security engineering, detection engineering, DFIR, etc? Feels like there's an abundance of offense but not so much other stuff.

I've gone a bit off the deep end and added more columns and functionality. Anyway, here's 49 Pico form-factor compatible boards compared in a table. PRs welcome. arturo182.github.io/pico-compati...

userland ROP on day 1 💪

Had completely missed that Infineon released new FX10/FX20 chips, making it accessible to anyone to get 10 or 20 Gbps USB for custom projects. So, what are we building this time? www.infineon.com/cms/en/produ...

Take this quiz, for example stefansf.de/c-quiz/ I think you'll find at least some of the answers surprising (I know I do, and I've seen it before!).

Intel launched the Pentium processor in 1993. Unfortunately, dividing sometimes gave a slightly wrong answer, the famous FDIV bug. Replacing the faulty chips cost Intel $475 million. I reverse-engineered the circuitry and can explain the bug. 1/9
