Day 5 - Another calculator project that is waiting its turn! Nothing too special on the technical side about this one, but certainly a piece of history! #TWAAC
A close up of an old calculator, showing "0." in an LED display.

Day 4 - And digital troubleshooting on a revision 1 PCB. From my paddle game project: trying out a fix for a problem before ordering the re-made part! #TWAAC
A bunch of DIP ICs on a PCB; some random pins are connected with colorful jumper leads.

Nixies! Some awesome calculator action here! This is the Sanyo caluclator, with the rightmost digit still bleeding into the leftmost during rollover, because there is a flaky short in it somewhere. #TWAAC
A powered on, but bare PCB with eight nixies, showing varoius digits; first and last are "bleeding" into each other, having shared ghost digits...

Day 2 - And coming up with an LED matrix display, made on top of a ceramic base. This beauty is part of the HP-IB tester. #TWAAC
A close up of a white ceramic carrier, containing golden contact traces and three 5 by 7 LEDs matrices.

Day 1 - Here we have an improvised fuse; to replace an SMD part until the spare part got delivered. I still think this is one of the more hilarious botches I made so far... even though it's only temparary! #TWAAC
A PCB with many tiny surface mount parts and one huge glass fuse holder soldered right across.

You might have noticed: I'm doing my "Tinkering Advent Calendar" again. I am sorry in advance if the pictures might be a bit repetitive one way or the other, but with so much going on this year, I ended up with only a few unique ones. Anyhow: pleyse enjoy or ignore the upcoming daily images! Thanks!

I went to the cinema yesterday and watched the first available screening of Zootopia 2 (in English and 3D) - quite the experience, I must say! If you go, be sure to stay for the post credit scene! Funny and foreshadowing! Somehow the "and what's your last name?" joke stuck in my head... #zootopia2

A comic of two foxes, one of whom is blue, the other is green. In this one, Blue is sitting next to Green, who has curled up into a tight ball, looking miserable. Green: Would you still love me if I never got better? Blue hesitates a moment before answering. Blue: What a silly thing to ask. Joining Green on the floor, Blue wraps himself around Green, who doesn't seem as sad anymore. Blue: I would love you even if you got worse.

The owner of this business is a old, wonderful friend & a former employer of mine, so please, I need all of my Pacific Northwest followers keeping an eye out for this stuff, especially if you run in nerd circles, so that his dream business, built via decades of grinding, can keep running.

KIRO 7 ran an article and two TV pieces on the theft of a box truck full of arcade PCBs, artwork, and machines from my workplace yesterday. If anyone in the Seattle area sees someone offloading a ton of CPS2/NAOMI/Neo Geo PCBs, stuff of that nature, please reach out.

A comic of two foxes, one of whom is blue, the other is green. In this one, Blue jumps in shock as Green floats idly by him. Green: I don't feel like doing today. Blue turns his head to follow where Green is going as Green floats further away. Blue: Doing what today? Green: Just the whole day. Any of it. As Green drifts out of sight, Blue raises his eyebrow, puzzled, watching where Green drifted off to. Blue: Also why are you floating? Green, out of frame: I got excommuned by gravity. Blue stares after Green, now in blank bafflement. Blue: ...What?

A comic of two foxes, one of whom is blue, the other is green. In this one, Blue looks curiously at a pie which Green has placed on a plate on the table, while Green looks at him with joy and pride. Green: I have made a sidequest pie! Blue listens patiently as Green goes on. Green: Flour from the mill we visited once, mushrooms that we gathered with your mom, homegrown parsley and basil... Almost all ingredients were things we've made or gathered on adventures! Both foxes turn back to look at the pie. Blue: How does it taste? Green: Bad.
