Got tired of this project but I finished the important piece of the puzzle. Should I just publish my nasty code as is, or try to keep working on it?

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.

So I found an old Pentium (probably 133) which sparked an idea for a project. Stupid but fun? Doesn't matter! I want to build a breakout board that lets me bring up the CPU with an FPGA. Emulate the Northbridge, interface with some external RAM, implement PCI peripherals.

[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...

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)!

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)

Started working on my Nintendo DS Lite video capture to HDMI project today after weeks of zero motivation. Huzzah! Fun fact, the fastest signals here are about 10 times slower than on the N64 (~5.5 MHz vs ~50 IIRC), which reduces the risk for signal integrity problems.

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.

Funky, no google results for NINTENDO2175. My hash is 5f855fdf258261af2a0c92d5e01e4a179e57d91acf0c3a0c0773407bd987ad8a. Yours too or do they differ?

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

What’s your favorite tool or method to find ROP gadgets in MIPS binaries?

Oops I bricked my device! After poking around and possibly feeding some back-currents in the wrong place, I get the following behavior: UART should run at 115200 but actually runs at 184615 baud, and gets stuck after the bootloader. What would you investigate first? Sounds like a clock-issue.

Alright, let's do a teardown, dump flash and such, and see how far we can get from absolutely zero of the TP-Link Archer AX12 wifi router. www.twitch.tv/kbeckmann

Is there a tool like sniffrom that supports Quad-SPI?

How does the new iOS inactivity reboot work? What does it protect from? I reverse engineered the kernel extension and the secure enclave processor, where this feature is implemented. naehrdine.blogspot.com/2024/11/reve...
