Folks, Michele has the most amazing science-inspired artwork.
Check her store and get something for the science-minded in your life.
Checking out her store now - maybe virus tie for me, brain tie for my doctor son, neuron scarf for my vet wife. Gotta set a budget so I don't go to crazy, haha.

I was obsessed with making some sort of collection. So I made a 'Field Guide'-like shirt design of Adafruit boards. Lemme know what you think.
There's an easter egg, too, for those who have one of these boards. But you need the shirt to see it.

More variations. This one with the Signetics logos and two iconic products of theirs: the NE555 timer and the µA741 op-amp.
On the shirts, I have variants with a large design, or small as a chest badge.
Of course, I draw these as I think they are cool. Real question is if others think so, too. 😁

Arduino came out with a clarification of the changes that so rattled the maker community.
The changes were related to cloud services (as many suggested). Everything that was open-licensed is still, there is no patent grab, or restrictions on reverse engineering.

My first blog was called Cognections ('cognitive connections') - first on TypePad and then hosted myself. About 15 years ago, I changed to Molecularist (as in 'works with molecules').
Was about to take @molecularist.bsky.social but someone beat me to it (👋🏽).

Oy vey. My Arduino-Qualcomm post got picked up by the Adafruit blog yesterday (kiitos, @anneb.bsky.social) and my quiet personal blog (molecularist.com) got a ton of visitors I wasn't ready for. Today, I went around updating some pages, including this one.

Another time-lapse of one of my illustrations. Note the VitaminQ cap in the center. And are those variable caps to the right?
My challenge right now is to understand what designs folks would actually wear. The good news, there's someone out there with this design on a shirt of mine. Haha.

Did Qualcomm kill Arduino for good? | Molecularist
The maker community worried Qualcomm would kill the Arduino ethos. New T&Cs confirm the community's worst fears. Here's what's at stake, what Qualcomm got wrong, and what might still be salvaged.

Odd being back on the socials. I find myself reconstituting another more promising time as I find those from long ago in the interesting places of Bluesky.
Maybe not that close-knit era of early Twitter or Flickr, but warm echoes.
[Ok, been here only 10 days, so maybe I shouldn't get worked up 🙂]

I’ve also been illustrating popular dev boards. Here’s the much loved Raspberry Pi PICO.
One really gets a good feel for the physical aspects board this way. Doing the castellations and holes required patience tho haha.

A pretty one, the Neopixels cycle thru the season. The twist? The pixels get dementia.

Here's a time-lapse from Adobe Fresco, where I do all of my hand-drawn designs. I have an iPad Pro and Apple Pencil. I only use a few weights of vector pencils. I use that blaze orange for highlights.
These are versions of the famous #chiptune #SID chips from #MOS (6581) and #Commodore.

Sometimes when working on a design, I like to explore variations to see what resonates with folks. All of these are hand-drawn. Even the logo and MOS-stylyzed #SID.
Here are variations of the #MOS logo with the famous 6581 and 6502 chips. (turn on the audio for appropriate #chiptune music, haha)

I did a series of Singetics designs around their cool logos. This is an early Signetics µA741 Opamp (originally designed by Fairchild). Basically this model became the canonical opamp, down to the pins, IIRC.

Seems I'm developing a style for my illustrations. Here's a 'build' video of me making my Intel 4004 design.
I was inspired early on when folks told me that when I do the work, _I_ show thru.
Yeah.
Now I like to stylize logos and other things too. Gives it a 'Charlie' feel.
