Check out my @tinytapeout.com personal ASIC project loaded up into the new Tiny Tapeout Explorer! An interactive simulator, all in a browser. Very cool. 😎 znah.net/tiny_explore...
Woohoo!! 80386 assembly language running on my ULX3S! Many thanks to #nand2mario for sharing the z386 Verilog code.

I've created a new @tinytapeout.com channel on the Radiona Discord to discuss all things ULX3S / ULX4M and general FPGA development that you might want to bring to an ASIC.
California’s attack on 3D printing is heading to the Senate. Here’s how it has changed, and why we still oppose it. www.eff.org/deeplinks/2...
We Can Still Stop California’s 3D Printer Surveillance Scheme
Ignoring EFF’s warnings about the dangers and impossibility of implementing a new mandate for 3D print surveillance software, the California State Assembly has signed off on legislation to do just

This circular region on the 2D rendering of my @tinytapeout.com ASIC project: that's the RING oscillator array of inverters!
Hardware Entropy Explorer: UART/SPI TRNG and PUF Submitted my 8th (and hopefully final!), successful update to @tinytapeout.com GF26a ASIC Shuttle. Deadline is about 24 hours from now. Oh, the suspense! github.com/gojimmypi/tt...
Mini MOSBius is a fantastic, practical tool for learning the fundamentals of analog microelectronics. It’s like an FPGA, but with transistors, current mirrors, differential pairs and an opamp. It's now included on all our future Tiny Tapeout Sky130 based chips! tinytapeout.com/news/mini-mo...
Mini MOSBius - Tiny Tapeout
A playground for analog microelectronics on TTSKY25a and all future Sky shuttles.

We are reverse-engineering the meaning of the 8087's microcode. For more details, see my latest article: www.righto.com/2026/05/micr...
Microcode inside the Intel 8087 floating-point chip: register exchange
In 1980, Intel introduced the 8087 floating-point chip, a co-processor that made floating-point operations up to 100 times faster. This chip...

Finally! This should be a no-brainer in that the GPLv2 license was violated. This falls squarely in the #RightToRepair category. I'm looking forward to open source alternatives to all the crap-ware laden devices that will otherwise end up in landfills. Thank you SFC.
If you're at the RISC-V summit in Minneapolis, @danielmangum.com's talk tomorrow is a can't miss!
Come to my talk at RISC-V Summit tomorrow to see me connect things to the internet that probably shouldn’t be connected to the internet.
Meetup at Radiona Zagreb TODAY, May 15. Show-n-tell on my new ULX3S enclosure, a little bit about Tiny Tapeout and my project, various FPGA topics and general geekery. All welcome!
Zagreb FPGA and #FreeStyleGeekery meetup at #Radiona! I'll be talking about my new ULX3S enclosure and @tinytapeout.com ASIC projects, other speakers on FPGA and more... thanks @gmahovlic.bsky.social 15 May. Link in reply.

The Radiona ULX3S hub site now honors device dark mode! Sunglasses no longer needed 😎 I also added a Tiny Tapeout section, as (pending a few Pull Request merges) Lattice #ECP5 FPGA support for testing your ASIC design on the #ULX3S is coming to @tinytapeout.com
Until you physically TOUCH and use a product, you never really know how it might be used or what features might be missing. Here I'm using the lanyard hook on my new ULX3S FPGA enclosure as a GPIO hook-up wire restraint! I had never considered adding a face wire restraint.
Black Magic Debug is now officially moved to #codeberg! We put together a blog post describing how you can redirect your cloned repositories, continue working on your PRs, as well as some reasoning behind the move. 🧳 Let us know if you have questions or comments! :) black-magic.org/blog/2026-04...
We moved to Codeberg
Hi everyone! As some of you might have noticed we moved Black Magic Debug to Codeberg. All the repositories that used to be hosted on GitHub are now marked as archived, and an archive branch is set...
