A Navajo weaving of an integrated circuit: the 555 timer(www.righto.com)

The 555 timer is iconic. Just iconic. I wonder how many billions of them have been shipped over the years?

It's really fortunate that the history of the 555 timer is really well documented. Its inventor, Hans Camenzind, wrote several books, and even had a Youtube channel in his later years[1]. It's a shame that so many iconic chips that have changed the world aren't so well documented. I went down a real rabbithole a while ago trying to find in-depth information about the Hitachi HD44780. I couldn't even decisively pin down exactly what year it was first manufactured. It's interesting to think of microchip designs as a kind of artistic legacy: Chips like the 555 have had an enormous impact on modern history.

Likely 1985.

I did see this article when I was researching, but it's incorrect. You can find references to the HD44780 in earlier catalogs. The earliest reference I can find is 1981: https://archive.org/details/Hitachi-DotMarixLiquidCrystalDis...

It's also referenced in this catalog from 1982: https://bitsavers.org/components/hitachi/_dataBooks/1982_Hit...

Likely the first year of manufacture was 1981/82.

That 1981 document says "preliminary", which suggests very limited trial production. Even the 1985 reference I found is "advance". First tape-out may have been earlier than that. Have you tried asking Hitachi (apparently now Renesas) about it? It's more likely that this information is available on the Japanese part of the internet.

Try 1972; taped out in 1971.

Reminded me of this “Navajo weaver inspired by video games”: https://www.youtube.com/watch?v=TrDZIyYSMfI

This is so cool. So if they used twists of steel wires or similar as string for the white parts, they could have a functional circuit.

They'd still need the electrical components, such as the transistors and passive components

Saw an exhibit with some of her work, I think in Albuquerque. Was surprised/delighted to see weavings of circuits.

Very cool art piece!

be cool if the creator used semi-conducting threads and it actually worked

This is the kind of thing that can start conspiracy theories of time travelers :)

My immediate thought was "Nazca lines of a 555? Yes".

I have a Displate of a 555 in my little maker corner someone gifted me once: https://eikehein.com/assets/images/makercorner.jpg

I demand to know what that construction of aluminium extrusions is. They're my pet material.

That's a pretty darn cool looking thing.

Funny how, guided by pure mechanical necessity, pretty stuff can arise.

I've always thought that clockwork, chips and other machines were pretty.

And fractals. ( https://fleen.org/i40.png ) And plants and animals too. And weathered rock.

Which leads me to consider what isn't pretty. Naivety?
