Part of the joy of visiting another country is noticing how everyday infrastructure looks different than at home.

Es hat wieder 30°C, erstmal Lebkuchen kaufen!

If you stick a single mode fiber lit up by a UV laser on a micro manipulator, you can get a micrometer-resolution 3D resin printer: https://www.youtube.com/watch?v=UvV2CH5il3Q

The other videos on this channel are also worth watching.

If a scandal were to happen at the hackcenter, would that be A20 Gate? #mrmcd26

(Idk if that reference is too obscure)

Footprint so cursed, I got nerd-sniped into adding some new features to Horizon EDA q_q

Case in point: L-Shaped pads. Custom padstacks for odd-shaped pads have been a core feature basically since day 0. However, for some reason I decided that you can only rotate and not mirror pads, requiring drawing two padstacks for such a package.

It's now possible to mirror pads so I only needed to draw the L-shaped pad once 😎

Vendors will totally put 1½ pages of this table in their datasheet rather than just stating that the gateline is encoded as 9 bits, LSB first.

Ob diese Dampflokomotive wohl ETCS-Ausrüstung hat? 🤔 #fat26 (ein bisschen zu spät, ich weiß)

Procrastinated submitting a board my implementing voltage divider and resistor ratio calculation in Horizon EDA… Instead of punching resistor values into a calculator, just selecting two resistors on the schematic now shows the ratio for various combinations right into the head-up display.

Clicking on the link pops up a small voltage divider calculator.

@whitequark@social.treehouse.systems @aryl@mastodon.social Cool! In the past decade or so thermal imaging cameras went from

• something only well-funded labs or companies have
• to something you can get hold of if you're lucky on eBay
• to something you can just buy for 300€

As far as I can tell, X-Ray machines are currently in stage 2. This one looks like we're getting closer to stage 3, i.e. something you can just buy for ~1000€.

We can launch a crewed rocket to the moon, but can't make a mission timer that uses tabular figures 😭

> As a rule, the higher the clock frequency and the higher the voltage, the more instructions can be retired by the CPU over a unit of time, […]

🧐 Well, that's one way of saying "if you increase the clock frequency, a CPU runs faster'. But who says it like that?

Looks at author.

Sees @intel.com email address.

Well, that explains everything.

Translunar Injection sounds much more ominous if you don't know it's about orbital maneuvers

Minor detail about an ordinary LCD thermometer: It displays temperature with 0.1°C resolution and min/max temperature to 1°C. The lazy way of implementing min/max therefore would be rounding the displayed temperature to 1°C resolution and using that to accumulate min/max.

However, it rounds down for min and up for max, so it's guaranteed that the temperature was actually between the displayed min/max readings. If it's 10.2°C and you reset it, min reads 10°C and max 11°C.

Just in time for FOSDEM, Dune 3D version 1.4 is out! https://github.com/dune3d/dune3d/releases/tag/v1.4.0

Release highlights include DXF export, improved constraining workflow and a new navigation cube for quickly switching views.

See you in the CAD devroom 👋 https://fosdem.org/2026/schedule/event/UUVWPM-dune_3d_-_2_12_years_in_the_3rd_dimension/

TBH, I wouldn't know what else to use. SDI hasn't really found its way into all niches previously occupied by composite video.

Technischer Fortschritt und so...
