Discrete6502 – one thing led to another
Disclaimer, I have not yet placed the order. But JLCPCB have so far excepted all files and config so I have 1 more button to press. If anyone see some obvious mistake please send feedback. This project grew out of curiosity. Loved the https://monster6502.com/ project but that is on another level. Here I tried to stay "reasonable" and added a Raspberry Pico 2 W on the back to drive it all. But also, was curious if Claude could pull this off. Guess I will have to place that order to call the cards.

In plain words
Discrete6502 is a hardware project that recreates a 6502 microprocessor using discrete components, inspired by the Monster6502 project but designed to be more practical in scale. It incorporates a Raspberry Pico 2 W to control the discrete logic circuits. The project was designed with assistance from Claude AI and is ready for manufacturing through JLCPCB, though the maker has not yet finalized the production order. It appeals to electronics enthusiasts and retrocomputing hobbyists interested in understanding processor architecture at the component level.

A working MOS 6502 CPU rebuilt from 4,051 individual surface-mount transistors on a 291 x 322 mm six-layer board that reproduces the original die layout. It runs programs.
A MOS 6502 CPU rebuilt from 4,051 individual transistors . No chips and no FPGA. The board reproduces the original silicon die, transistor for transistor. The MOS 6502 powered the Apple II, the Commodore 64, the NES and the BBC Micro. Roughly 3,500 transistors sit inside its package, on a fingernail of silicon. This project takes that exact circuit and rebuilds it from parts you can see. Every transistor becomes a separate SOT-323 package. The board is the size of a sheet of A4 paper. It is not a simulation and not an emulation. The logic is the real thing. It is the same dynamic NMOS circuit that the original used, and it runs the same instructions. It is a few thousand times larger and a…from epatel.github.io

m6502, a 6502 CPU for FPGAs and Tiny TapeoutFeb 2026 · github.com · ▲5Hey HN, Recently built an Apple II emulator and at the same time was getting into Tiny Tapeout and decided it would be cool to build a cycle-accurate 6502 CPU and an MCU for it. It's cycle accurate and the core itself should be 100% compatible with a stock MOS 6502 (would need to still test this though!). Tested on some FPGAs (fomu, ulx3s) and works great, hoping to get it taped out in the upcoming IHP26a shuttle. Also as part of the project I built a bus multiplexer to allow memory/bus access from an RP2040 to work around the limited pin count on Tiny Tapeout. This let's you load up…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
