Integrated System for Enhancing VIC Output
ISEVIC stands for Integrated System for Enhancing VIC output and is a cartridge for the C64 that uses the Tang Nano 20K FPGA to monitor the bus and recreate the C64 video for HDMI output. While a tremendous effort has gone into handling all the clever C64 tricks, this should be considered a 1.0 release as there are still some demos and games that exhibit bugs. Everything needed to build one is on the github page.
In plain words
ISEVIC is a cartridge for the Commodore 64 that uses an FPGA to intercept the console's video output and convert it to HDMI. It monitors the C64's bus to recreate video signals, handling the system's complex display tricks. Designed for retro computing enthusiasts and developers, it outputs modern digital video while preserving original C64 graphics. The project is in early release with some compatibility issues remaining in certain demos and games. Build instructions and files are available on GitHub.

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…
