Also, great for learning to code Circuit Python and prototyping ideas for other more adventurous builds.

Ugh, whenever I see cap-leak stories I shudder thinking of my old Mac II ('87) and early iMac ('99) - what might they look inside?

My illustration process: standing on the shoulders of giants - Grey and Slate, Haberdashers I've been struggling to define my process for creating hand-drawn designs. I have contextualized it within a long tradition of artists using optical and mechanical aids.

I’ve been trying to define my process for creating hand-drawn #maker #designs. In a post on my new Grey and Slate blog, I contextualize my process as part of a long tradition of #artists using optical and mechanical aids.

There's a #raspberrypi 'build' video, too.

Was a bit cheeky this weekend and worked up a #RAMaggedon shirt.

In the course of this, I had whipped up a #GPU drawing - a culprit in the RAM shortages. So I have a shirt of that, too.

See both here:

Do you recognize the GPU model?

A maker space with benches and materials for crafting, some stools, and artwork hung on the walls.

Visited a lovely new local #makerspace. The kind owner, tho setting up for class, took the time to show me around. It's a 'soft-tech' space for adults to work with textiles, paper, paints, yarn, and such. No CNCs or laser cutters.

Looking forward to making use of the space!

Ugh, didn't realize one couldn't change Reddit username after commenting. Now I am u/No_Magician1477 for eternity.

Or I could start again. Only have upvoted or commented a few times.

D'oh.

The RAM shortage is coming for everything you care about Did you think you could escape?

I keep thinking how long before we had a semblance of normal after the chip shortages of 2020-2021. And the pain we had to deal with in that period.

Once more, with (empty) feeling.

My latest #maker designs coming out in the next two weeks. Lots of #patents, a few specifically from #women #inventors (Margaret Knight, Beulah Henry, Margaret Crane).

I find the drawing of old patents to be really cool. I go for the visually interesting ones.

What do you think?

I received another commission to do some hand-drawn designs for shirts. Yay!

These were for an #Amiga clone by www.enterlogic.se

One of them you can see in the video below.

You can get this design and the four other variants here: greyandslate.etsy.com?search_query...

Ellen Eglin - Wikipedia

From Wikipedia:
"You know I am black and if it was known that a Negro woman patented the invention, white ladies would not buy the wringer; I was afraid to be known because of my color in having it introduced in the market, that is the only reason."

Researching for my Women Inventor's shirts, I stumbled on the story of Ellen F Eglin, who invented a clothes wringer ca. 1888.

She sold her invention thinking no one would buy something invented by a black woman.

Well, here's her patent, with a few mods.

Just some #maker-inspired shirts I'm releasing this week and next.

Recognize any of these circuits and components?

I mentioned a few weeks back a bunch of #maker-inspired designs I made for Valentine's Day.

As these things go, I released one last one, today.

Reminder: Time’s running out to order your V-Day shirt!

Check ‘em out here.

Followed a bunch of #makers and #electronics folks today (thank you @pimoroni.com for an old list of starter packs).

Hello, those who are following me back. Thanks!

By day, in the life sciences space. By night, krazy maker and also illustrator of marker-inspired art and design I put on shirts.

👋🏽

Wishing the best for Particle. Have built with their products and really like the folks I met there.

My eyes played a trick and scrambled clawdbot/moltbot into Murderbot.

We’re gonna get all worked up around safety and all Moltbot will want to do is be left alone to watch a gazillion hours of Rise and Fall of Sanctuary Moon 😁

Cool.

Not far to connecting it to wheels and motors.

Ok, so I will admit that my #maker shirts with illustrations sell the best. But I keep making text-only shirts, as they make me laugh or think and I want to share those. I mean, makers do sometimes buy text-only shirts, no?

In any case, this one was inspired by a suburban mom catalog, haha.

Cool. I threw myself upon the math and calibration of IMUs a while back for a few projects (actually, one was my first big one as a maker with the Tiny PICO). Tho, this last time, I finally gave up and just bought a BNO085 to do all the math for me.

But making your own calib tool is another level!

I made three city shirts. One of cities of top #maker vendors, one of top #PCB shops, and one of top #CNC and #3Dprinter companies.

Do you know what companies are represented by these cities?

While I am so thrilled with the things I've been designing and illustrating, my feed reminds me of the challenges in the greater world. But for various personal and professional reasons, I am not one to speak up in these channels.

That said, the quote below sums up my feelings quite well.

My latest design is a set of opamp schematics. Circuits and schematic symbols seem to be popular in my store. Which is fine, I have fun doing them. So, expect more, haha.

Arduino’s UNO Q is already getting some upgrades. The original version of the UNO Q paired Qualcomm’s Dragonwing QRB2210 processor with 2GB of RAM and 16GB of storage. A little over three months after it was announced alongside Qualcomm’s acquisition...

Any one use the Arduino UNO Q yet?

Yesterday was first time in ~8 months I didn't publish a new daily shirt design to my store.

Alas, I've fallen behind due to a busy December and start of year. Might have to miss a few days in the next week, too.

But I've a bunch of fun #maker designs to make this week. Watch this space!
