I may need to pause this restoration for a bit. It is looking like I may need to replace my alternator in my pickup and I only want one disassembled machine lying around at a time.

@twrightsman This is my first printer with a bowden tube instead of direct drive extruder. I will be tweaking settings for awhile I imagine to strike the balance between stringing and jamming. I'm looking forward to the increased build volume over my wanhao i3 plus.

I just got a new ⁨#3dprinter⁩ which means the next few days will be spent printing out upgrades and accessories for it. First, a bracket to hold the Raspberry Pi that controls it, along with a camera mount.

The way this mechanism works, only some of the gears from the keyboard mesh with the multiplication register gears. Numbers 5 and above are too far out of alignment to mesh with that register. For some reason (angles I guess) this doesn't affect the upper gears as much.

After spending most evenings before dinner tinkering, I think I've discovered the problem with multiplication. All 1s-4s transfer to the register while all 5s (and above) don't. I got 5s to work when pushing the carriage diagonally, so I think there is a carriage alignment issue.

Isn't She Lovely was just on the radio. Ever since I became a parent it gets me every time. But then Careless Whisper followed it and all I could think about was Sexy Sax Man. ⁨#truestory⁩ ⁨#rollercoaster⁩

I should have mentioned how to enable this if you are running Phosh on a Librem 5:

gsettings set sm.puri.phosh automatic-high-contrast true

Phosh has a new optional feature that uses the light sensor to switch to a high contrast theme whenever it detects you are in direct sunlight. Very cool, especially since it also applies to the lock screen and all GTK apps too. #Librem5

Ladies and Gentlemen, we have long division! ⁨#antique⁩ ⁨#calculator⁩

It also seems Apple's ad tracking rules exempt much of its own tracking behavior since it only shares the data it collects about you with itself and not third parties. At least according to this analysis: https://mobiledevmemo.com/att-advantages-apples-ad-network-heres-how-to-fix-that/

Interesting coincidence that after Apple added App Tracking Transparency to alert iPhone users to the data 3rd party apps collected for ads, adtech had to scramble for alternatives, such as Apple's own ad biz, which grew 238% to $3.7B in 2021 https://www.theverge.com/2022/8/14/23305200/iphone-more-ads-advertising-apple-maps-podcasts-books-mark-gurman-rumors

@JohanEmpa Actually if you look at the picture of the rear of the calculator you can see a metal cylinder that extends down into a large worm gear. That is what controls where the carriage is when shift stops occur and you can adjust it via screws at the top to shift it left and right.

@JohanEmpa Alignment between the top carriage and the bottom gears from the keyboard! Repairing shifting made the misalignment more obvious. It still isn't perfectly aligned though (falls out when left shifting during division for instance) so more tweaks are needed.

I was able to fix the shift mechanism with a few adjustments and while I was at it figured out what was wrong with the main accumulator so now addition and subtraction work. Next up: multiplication.
