Thank you for sharing. This is the C4004 - an early ceramic version of this historical chip (the first commercially successful 4-bit CPU). Here's a build video of my illustration of the design. [Artwork adapted from CC-licensed works. Full attributions: tinyurl.com/GSHattributi...

I have a thing for MOS Technology - the logos, the chips. Here's the 'build' video of this illustration.

But @smallrun.bsky.social doesn't, so Claude Code and I spent some time today building some glue scripts to move order info and tracking numbers between SmallRun and Printify (saves me from transcription errors). APIs rule! Cool?
Seems like another famous chip has hit 50 this year. Saw a nice historical article mentioned by @anneb.bsky.social in the @adafruit.com blog. Reminded me of when I sorta encountered Z80 products as a teen in the early 80s. greyandslate.com/blog/fifty-y...
Fifty years of the Z80 - Grey and Slate, Haberdashers
The Z80 is 50 this July (2026). My history briefly crossed with this chip when I was young. But now it's a popular design of mine.

Since @loudai.nl is now selling his creations on @smallrun.bsky.social, figured I'd add my USBSID-Pico designs there too: smallrun.net/products/sea...
Thank you for promoting this design. Quite a fun one to do. For your viewing pleasure - the building of the design.

My shirts are not ONLY #maker-inspired designs. I do have a section of Left-Field Quirky designs that begged to be made, so I made them and included in the store. Here's one. "Don't forget your greens" greyandslate.etsy.com/listing/4332...

At first I was doubtful of this UNO Q. But warming up to it fast. Pricey but so much in such a small package. App Lab is interesting, too. I see what they are getting at. But will it work? Is this a new version of original Arduino dream? And goodness to they pack components in. Details here.

Looking lookie what showed up. Got it via this competion: www.hackster.io/contests/inv... Got some work to do this weekend! Components: The UNO Q, @seeedstudio.com XIAO Sense (mic and camera), @adafruit.com MAX amp, speaker, dice, and some enclosure. An LLM in the mix too. Just not sure where.
Was checking Google visibility and was nice to see my designs show up. Ok, so was a bit specific. I was trying to see if my SmallRun listings would show up. But a thrill to see Google suggest a 'hand-drawn' category for the images. [Not to mention earlier searches revealing nicked designs...]

Feeling giddy - just ordered, for new projects, two of each: Seeed Sense (w/ camera), XIAO audio BFF and speaker, and the M5StickS3S. Been a while since I futzed with code and boards (today using Resident and ESP32 boards). Feels good. [hm, these might be some interesting things to illustrate...]

Where do you get maker-themed merch? How do you find out about them? I sell #maker themed shirts on Etsy and SmallRun. Do some promo here and on Insta. But, maker pubs are not so commercial-friendly. I've not many in-person opportunities to be commercial. And no strong evidence of word-of-mouth. 🤔
Cool. Someone just favorited all my @raspberrypi.com illustrations in my Etsy store I one go. Must be a RasPi lover, haha. Granted, my RasPi5 illustration is one of my top performers.
Not only do I have a store on @smallrun.bsky.social but those two shirts in the article image are mine! Thank you @hackadayofficial.bsky.social for the article! My #maker shirts are now on Etsy and SmallRun.
