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

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)

Sag mir, dass der Hörsaal seit 40 Jahren nicht renoviert wurde, ohne mir zu sagen, dass der Hörsaal seit 40 Jahren nicht renoviert wurde. #uplink26

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.

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

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/
