I completed my 3d printed mechanical digital clock! 🥳

I combined two of my seven segment displays with a geneva drive mechanism, so now they can count from 0 to 59!

I designed this contraption to combine four digits and correctly advance all of them so that they make a 24-hour clock. It's printing at the moment, no idea if this will work.

And I made this monstrosity that counts from 0 to 23 (ie. from 0 to 9 twice and then from 0 to 3). I've since redesigned all digits to use a single camshaft, which makes them smaller and run better.

The mechanism works! But I got some measurements wrong, so the big white part doesn't fit properly and needs to be reprinted...

marian42,
@marian42@mastodon.gamedev.place avatar

With the current design, the complete clock will have more than 120 parts!

I completed all four digits for my clock! It runs surprisingly smooth. The transition from 23:59 to 0 moves the most parts, so I expect that to have the most friction.

I made a mechanical 7-segment display:

@azonenberg There are some examples online of designs with hinges, I think the current solution is more elgant. The lighting is quite difficult to get right for the video, but IRL it's easy to tell which number it shows. I do consider adding LEDs so it is readable in the dark.

@azonenberg I think this is the concept you describe: https://www.youtube.com/watch?v=7NdiL5mjz14

But this is the asthetic I want to achieve: https://www.youtube.com/watch?v=YQLStT4RXVo

OS Bookworm, released last week, brings a big change for Python users, as we implement a change introduced by the Python community in upstream Debian: from Bookworm onwards, packages installed via pip must be installed into a Python Virtual Environment using venv.

@Raspberry_Pi Why though? This breaks so many existing tutorials and will add unnecessary confusion for newcomers. It's bad usability and lots of people will give up on learning raspberry pi just because of this change.

@maxbob @Raspberry_Pi there should be less barriers, not more!

I'm working on a new design for an orrery

marian42,
@marian42@mastodon.gamedev.place avatar

I started cutting some of the structural parts and some more gears. This part of the mechanism is working 🎉

marian42,
@marian42@mastodon.gamedev.place avatar

All the big gears are cut. They didn't turn out perfectly, but this shows that the basic concept of this orrery seems to work.

marian42,
@marian42@mastodon.gamedev.place avatar

Trying to figure out where the crank handle will go. Maybe here?

marian42,
@marian42@mastodon.gamedev.place avatar

These gemstones will be the planets!

@marian42@mastodon.gamedev.place avatar

This part in the bottom right will be used to operate the orrery. I'm also considering a motorized version. Next step is to replace the steel rods with ones of the correct length.

Here are my attempts at drilling holes into the planets. I've since learned that you're supposed to use water to cool the drill bit. 🙈

I'm setting up a motorized version. I saw JBVCreative recommend that you use a stepper motor because it's silent and that worked out great. It's magical to see all the gears moving without making any noise whatsover.

Here are the gears moving!⚙️

I replaced the Arduino with this Seeeduino, which fits on the breadboard. Now my orrery has USB-C 🤓

marian42,
@marian42@mastodon.gamedev.place avatar

I finally found some time to work on this. The axes have the correct length now and I got these cool stoppers that you can attach with a little screw.

marian42,
@marian42@mastodon.gamedev.place avatar

Sadly there is a lot of slack and backlash in this and sometimes it gets jammed.

marian42,
@marian42@mastodon.gamedev.place avatar

I'm testing adding these rings to support the axes on both ends to reduce slack. So far it seems to work.

marian42,
@marian42@mastodon.gamedev.place avatar

Made the remaining rings and started with the riders for the planets.
