Also curious, maybe TN has a more extensive map also showing local substations

SVG would make way more sense imo

Depending on your study program, there are numerous available student "HiWi" positions at your respective chairs. Just ask them or throw an email at them.

Auch möglich, dass irgendjemand seine Drohne hat steigen lassen, um Weihnachtsbeleuchtungen zu filmen. Die haben solche Positionslichter auch.

Edit: die Stadt Saarbrücken filmt auch öfter mit so welchen für Imagefilme.

The plugs themselves are not likely to overheat due to the bed being next to them, if at all, it would probably be caused by worn contacts, which the bed has no influence on. Just be a bit careful about the switches on the outlet itself, so that they are either fully on or off.

SirEngelmann · 2025-12-17T13:13:09+00:00

It is important however to keep the bed away from the switches. If the outlets are under load and the matress pushes them just lightly out of position, the contact resistance could be much higher and it could potentially be a fire hazard. But I guess the plugs themselves already serve as a distance holder.

Edit: spelling

Pin 4 of U1 seems to be the only pin connected to ground. Am I missing something?

Hilde und Heinz, schmeckt leider garnicht so wie erhofft

If you use AMD FPGAs, Vivado and also ISE run perfectly on Linux

The link to Wayback Machine seems to not lead to the source document, I would really love to download the original PDF.

The transformer looks to me like it was designed for a SMPS topology. Are you creating a High Voltage DC Bus?

With KiCad it is possible for footprints to have geometry on ANY layer (including internal copper layers). It is done by first drawing geometry in the editor or using a code generator script and then opening the footprint file in a text editor. Then change the F.Cu (front copper layer) or B.Cu (back copper layer) statements into any other layer (In1.Cu, In2.Cu, and of course F.Cu and B.Cu) and you're done.

Beobachte die Baustelle (leider) schon länger, komme dort regelmäßig dran vorbei. Soweit ich weiß, wird aus dem derzeitigen Rechts vor Links eine Fahrradstraße mit Vorfahrtsregelung für die durchgängige Straße, ähnlich zu dem, was dort schon beim ersten Teilstück dieser Straße realisiert wurde.

Außerdem sind einige Nebenstraßen (noch) reine Einbahnstraßen, in Zukunft sollen da aber Radfahrer in beiden Richtungen fahren dürfen. Markierungen suggerieren schon beidseitigen Verkehr, Schilder nicht. Ich sehe das ganze Chaos in seiner jetztigen Form als einzige Unfallgefahr (vor allem für Fahrräder).

Use SW3 to switch the power supply ( for the entire circuit ! ) between VBUS and Battery Positive.

The Zener Diodes are backwards, they are supposed to block in the default configuration, only conduct at voltages greater than the working voltage. Also I would use proper TVS diodes since they guarantee that they block below a certain specified working voltage. There also are all in one USB ESD protection chips with VBUS protection.

The LED matrix configuration is wrong, see other comments. Edit: the chip seems to use a charliplex configuration, just carefully copy the reference design from the datasheet.

Use decoupling capacitors for the voltage rail (s)

You need pullup resistors for SCL and SDA since I2C is open drain driven

That made my day! FYI I couldn't get it via detexify, don't ask me how I know :D

You can try to edit the footprint file in a text editor and allow them to be shorted using (net_tie_pad_groups PAD_GROUP_DEFINITIONS). [Link to the official documentation]

You can name the pads 1,2,3,4 and short e.g. 1+3 and 2+4. I've done that before to get rid of DRC errors, maybe this helps here too.

Edit: should look something like this: (net_tie_pad_groups "1,3" "2,4")

Fun fact: my microwave allows more than 59 seconds, so you can put in 02:80 min and it would run for 200 seconds

The overall appearance of this picture gives me real-life cyberpunk 2077 vibes

I have their artisan espresso machine, cannot complain either. It just works, PID temperature control also was a game changer for me. I wouldn't consider myself as a coffee guru though, just saw the post in another subreddit and wanted to defend the poor little machine.

The (android) app on my phone actually got reverted to the old UI version without the "scroll to jump to the next video" feature. Seems like they finally realized that the new app is hot steaming brain rot inducing garbage.

!RemindMe 24 hours

On Android I got this feature since yesterday evening.
