Guess what I have on my desk to test next week...? Two more RISC-V cores to add on to the 8 inside this laptop! This is a neat little RP2350 GPIO expansion card for Framework devices, which is plugged into the DC ROMA Mainboard II, with an 8-core P550 onboard :)

I've been playing with some very expensive/accurate (down to single-ns-level) GPS receivers lately. But I wanted to see how a cheap ($10) USB receiver would fare... and it's easy enough to just connect to it from my Mac! Blog post with the details:

There are few things that grate on me more than people copying and pasting straight ChatGPT generated comments on blogs, videos, etc. At least do the minimum effort of typing out your own thought based on their summary and your own brain.

I got The Witcher 3 running on RISC-V Linux... just don't look too closely at the fps!

JetKVM has a rackmount! A local STL-area maker designed a rackmount for 1, 2, 4, or even *6* JetKVMs in 1U, and it can be 3D printed, or even laser cut from metal. Very cool:

Oh boy. I had clicked off MKBHD's latest video a minute in since I realized it was full sponsored and just hitting DJI talking points. But doing driving reckless for a short clip in a video is always wrong. Don't drive 60 over the limit. Not ever, esp for content.

Took a little time this morning to clean up the rack and finally install a separate 2.5G switch! Having redundant PSUs makes it so easy to reroute power cables when messing around :)

Met @npub1vdgc...zgnu today. His Pi-based cubesat is used to teach security for spacecraft, and it's now in the studio. Would you like to know more?

Successful deployment earlier this week, videos on pause for a couple weeks so I can help the other kids get to and fro and prep meals while my wife recovers! (Though might wrap up the latest Geerling Engineering video since it's 95% done!)

Finally, someone designed a 3D printer for Australians! The Positron V3.2 is a fun, portable printer. I built one and tested off-grid portable 3D printing in my latest video:
