I'm new to the instance but not new to Mastodon.

I used to be on mastodon.xyz but it mostly for the French folk, and now the instance keeps shutting down without warning.

I'm a Python & Django programmer with some interest in Linux, automation and CI. I find working on 3D printers a meditative experience. I also have a very small garden.

I'm mostly posting about my ongoing side projects hashtags for which are:

Strongly recommend Signals to Danger podcast if you’re interested in engineering disasters & postmortems.

The presenter is a railwayman and gives an excellent level of detail and deep-dive into the operation and procedures of the UK rail network across the years in examination of many significant rail accidents. A great one for long trips and even background listening if you want to. The most recent episode, Quintinshill 1915, dissects the deadliest accident in UK rail history with scientific but sympathetic rigour. It’s about as graphic as any episodes get.
I particularly appreciate the way Daniel Fox is scrupulous about detailing the exact procedures that should have been followed, with clarifying examples for non-rail experts, how they were contravened, and how it fits into the broader safety management system of the rail network.
It’s definitely for nerdy folks but very well done for a one-person operation.

Reminder for everyone:

If you join in a conversation that has CWs, please don't strip the CWs when you reply. People added them for reasons.

Thank you.

there are literally activists out there who think everyone should read theory but can't be bothered to learn how to move off Facebook, Instagram & Twitter, which is VASTLY easier.

I love this video showcasing some unconventional uses for #inkscape ... if you're not familiar with his channel, you should really check it out. My fav for inkscape tutorials!

I've been doing some 3D modeling, designing another spotlight.

Here are the few things I learned for this project:

- When modeling shells use all of the existing parts (vitamins) to see how parts fit together. This saves a lot of filament.

- Create rough models for parts I don't have, to see how they would fit

- (more specific to openscad) Use 2d shapes and extrude them

- 2d polygons are flexible, but time consuming to design. It's ok to get started by combining squares and circles

I’m building another LED light from stuff I have lying around. I’m reusing heat sink from an old server.

I tapped the screws for the COB. I ended up breaking a tap, but it was at the very last hole, so i was able to finish this part of the project.

This is 50W light so it will need some active cooling. I ran it like this for a bit and the heatsink reached 55C

My own little parametric LED lamp design, made with #OpenSCAD.

Will publish this as an open design soon. What do you think? Reminds me of omnipresent lava lamps in my youth 😆

UI Pet Peeve: Don't use flags of countries for language selection.

It doesn't work for English (Union Jack? Star-Spangled Banner?), forces Austrians to click on the flag of a neighbor country, and lets large parts of Africa only choose the flag of a former colonizer.

Always express times for meetings including date (as YYYY-MM-DD, or else month given as name instead of number, to avoid DD/MM or MM/DD confusion), day of week, time in 24-hour format with at least two time zones (local time and UTC). Indicate 12:00 also as noon, and 24:00 as midnight. The redundant information is there to make it easier to spot errors.

Thus: Monday, 2021-11-08, at 12:00 (noon) in Finnish time, or 10:00 UTC.

Or: Monday, Nov 8, at 12 (noon) Finland (10 UTC).

(Not: 8/11 at 12)

I got inspired by a design of a clothes peg that is printed in one piece and decided to create it in Solvespace. First attempt. The spring on the peg works surprisingly good even with regular PLA.
