I really don’t know what I’m doing when it comes to live-streaming, but if anyone wants to ask questions here I’ll answer them, or you can join the stream here? I am not good at this yet 🙃. https://streamyard.com/zqzcskearb

Live from the workshop of @the_prepared in Brooklyn: building the Open Book Abridged Edition! https://www.pscp.tv/w/c4u4WzFyYWpaeU5Eb0FuS3p8MVJEeGxQUU5YTGp4TOjp-V8_THcSuWzWyLXiEkd4s2YtcAeDSaqDwbLXRq6d

probably closer to 2:15, actually; still laying out parts and setting up the stream.

ADVISORY: in about three hours’ time (2:00 PM Eastern!) I will be live-streaming on twitter as I build and test the second rev of the Open Book Abridged Edition. Can’t promise it’ll work! But I can promise we’ll learn something, if nothing else. Link should appear in my timeline.

I ended up using a full RPi for this. The satellite images I wanted were all sized wrong, and I couldn’t untangle embedded resizing. I also needed to dither to 7 e-paper colors; between all my requirements, it was easier to just use a platform where I could import pillow.

the weekend is here and I need to assemble and bring up this open book prototype next. simpler SD card slot. castellated EPD module. This could be the simple low-cost book I’ve been chasing.
is livestreaming soldering something folks would be interested in? thinking maybe sunday.

Followed back so I think you can DM! And I used JLCPCB as a fab, they seem to be great for this kind of PCB art stuff. The process was pretty straightforward; exported each layer from Illustrator as a 500 dpi bitmap, and then imported each in Eagle with its bitmap import script.

Replying to @bokmann
Buffers or inverters are definitely the correct answer; I may go back and do it right for V2. Re: the front, it’s actually FR4! It’s a circuit board from the same fab, but no electrical connections; just carefully laid layers of soldermask and silkscreen (designed in Illustrator)

the switch actually changes the clock speed from “everything is a blur” to something you can actually see with eyes. M1 lights when fetching an instruction, plus you can see individual writes and reads on the bus and the exact addresses where they’re happening. This was the goal!

this retrocomputer build would not be complete without a “magic” / “more magic” switch bolted to the side.

This is far from the most significant example. But the backlash we are living through is terrifying, it feels like it’s happening everywhere, and it will get worse before it gets better. https://amp.beaconjournal.com/amp/7508217002

Nowhere as of yet; I designed this as a one-off for my own curiosity, but as I play with it more I may share the design, either source files, on tindie, or both.

Swiss Army Knife (a slim one with a ballpoint pen), but I’ve also added some stuff to it. The needle and thread has helped in a pinch.

Some photos from the build. There were a couple of missteps — green is still dim in the end, and the UART indicators should be active low — but overall, I have to say, I had a theory of how this would come together and it just did, full stop :)
(original)
the lights! they blinken! This is me loading BASIC, entering a program and running it. You can see the address bus jump around in memory while the blue MEM REQ light is on; once it runs you see alternating calculations, and yellow flashes of IO REQ as the program outputs results.

Thanks! The idea is that it will plug in to a slot on the RC2014 retrocomputer, and show the state of various signals on the bus. https://rc2014.co.uk/

It’s just something I designed on a lark last month; if it works well and there is interest, I might make it a kit, but for now it’s just a thing I’m playing with.

there are a great many things in this box. watch panels. nfc antennas. a new book idea. But right now I cannot get over how perfectly the blinkenlights module turned out. I mean, look at it! It’s beautiful. too tired to solder today but stoked to get it built tomorrow.

I was sad to find out that I couldn’t modify MacOS’s press-and-hold accent keys — thanks, SIP — but it turns out there’s software that makes it easy to create a keyboard layout from scratch. https://software.sil.org/ukelele/
From there I just had to have him draw me the keyboard he wanted.

it doesn’t work at any price point. even if it were $20 a month, the users with enough disposable income to opt out are the very ones that advertisers most want to shove messages at.

selfishly I just don’t want the distraction; to the extent that I have broad ideological ideas about these things, it’s less ‘fuck these companies’ and more ‘fuck this creepy panopticon of an ad tech system, I want out’

after a couple years of blocking, I see almost no ads in my feed. maybe once every few weeks I get a new spate of them, but I block those and then I’m good for maybe another month. The irony is I would love to support twitter AND get an ad free experience. maybe they’ll let me.

Replying to @josecastillo
until then I will continue to diligently block every advertiser that pops up in my feed.

if Twitter Blue removes ads, I will sign up within seconds. if not, I don’t really see the point. https://twitter.com/engadget/status/1398040319170600963

in this week’s Digikey order: some very specific resistor values for the blinkenlights board. I’m trying not to exceed 1 mA per signal line, but green feels a bit dim with a 3.2KΩ current limiting resistor. hoping to achieve a little more brightness without going too far over.

My circuit boards have cleared customs in Hong Kong! The next DHL flight out leaves Friday at 6:10 AM and lands in Alaska Thursday at 10:30 PM. (don’t think about it.) anyway, if they show up in Cincinnati sometime tomorrow, I’ll know this is the route they took.

WOO LOGISTICS-NERD-OUT THREAD CONTINUES! Parts arrived today via UPS 1112. I know because only one of the two flights were delayed & my parts were on the late one. Now my boards have been picked up in Shenzhen, and I’m wondering which couriers handle DHL flights out of Hong Kong.

it really is such a wild dance. these are all UPS cargo planes converging on Louisville, Kentucky in the middle of the night. every night, this is happening; then every day, boxes get to places. it’s impressive. it does not feel sustainable. and yet. we all keep doing it.

alas, my circuit boards are still waiting for a courier to pick them up in Shenzhen, so the wait to build my projects will almost certainly slip into next week.

update: UPS says my parts left Sioux Falls at 9:51 PM, so they’re almost certainly on board UPS 3571, landing in Louisville in a half hour. from there there are two early morning flights to JFK; then they’ll make the last mile to the shop by midday tomorrow. The things we can do.

It’s a machine learning vision of Manhattan; you could choose to see the spires of the Empire State or the Chrysler building in silhouette, or something like a green Central Park from above. but it’s a hallucination in the end, all computed from data. a place imagined (or not).
