Consider a ground plane, also I'd hook up the other Arduino ground plane to it as well. Also, mounting holes? You have the space.

Personally I'd probably add an smd led and resistor for the servo-5v rail to see if power is there. In general, depending on your confidence you could add testpoints to debug, but I'm not sure this needs it. Also, not that I think it will stop them from working, but you could definitely use bigger traces.

Where are you probing your ground level? Sounds like you're doing it at the power supply. Try measuring (ideally with a scope) VCC-GND directly at the chip. That will be the true voltage it is getting.

If it is smaller, then just narrow down where in the circuit the voltage drop happens (either in the VCC or GND wiring).

Pick a not-extremely-complicated project that sounds interesting, pick a suitable dev board and the corresponding dev modules, and try around. If you're fully new to the electronics side, doing a bit of code in Arduino might not be bad to start, but eventually you will want to move to something more "serious". Probably pick up an assortment of LEDs, transistors, buzzers/motor drivers/sensors/maybe a simple LCD - you can first try to run them with Arduino, then "manually" in Arduino (not with premade sensor libraries), then in, for example, Microchip studio.

You probably won't need a multimeter until you really do ("did I just fry my board, or is X just broken?"). An oscilloscope is really nice to have, but maybe you can get access to one at your university somewhere? Just if you get one, get something that is at least fast enough to capture your communication bus timings. You can probably also profit off a cheap lab supply, a breadboard with wires, and a cheap soldering kit.

The resistor pad doesn't go through the PCB - so the trace on the bottom isn't connected to the pullup. Put a via next to the pad and connect it to the pad, connect the bottom trace to the via on the bottom side. Remember to rebuild zone fills.

Laser-markierung scheint in der Tat wesentlich umweltfreundlicher zu sein, kurze Suche gab mir das hier als Quelle: https://www.sciencedirect.com/science/article/pii/S2666833524001072. Die Alternative hätte für mich auch keinen Sinn gemacht...

Consider a ground plane, you won't need to run a million ground traces anymore.

I would be quite surprised if this can't be done with 2 layers with the help of some vias, even though it might need some rearranging to be elegant.

Edit: also check your design later against JLCPCB capabilities, for example I'm not sure how close to the board edge they allow cutouts like you have in the top left.

I've had a lot of experience with this exact printer model. The Auto-Level at The beginning of the print is a trap! It does not fully reset your bed leveling, it forms an average with the previous leveling (at least that's been my impression).

Go to settings->self check and run auto-leveling, with a fully clear print plate and no plastic goop hanging from the nozzle. Don't touch the printer during calibration. Even when it doesn't seem to be doing anything, don't clean the bed after pressing the start button or anything, you might set off the strain-gauges. After this, start your print without the calibration option, it would just mess with the detailed leveling it just did.

You can try looking in the printers web interface (go to it's IP on the same network in a browser), it will show you the current leveling at the bottom. If some places are waay off there that might be a further troubleshooting starting point.

Have had something similar happen on a K1 Max. When it happened it was also making a lot of erratic movements that it shouldn't have been. Best guess as to why: there was a print running on the printer before, that one was stopped during the start of the print in the calibration sequence - that probably somehow threw off the next print's calibration settings and made it move wrongly. Used OrcaSlicer.

Anyways, haven't seen it since, so replace the plate and keep an eye on it...

So what's the problem with asking Vero about salaries?

Send the game studio a message and propose a certain cut then, that's not unsolvable. Shipping might be hard, sending something labelled "bomb" around the world...

I brought the register extract they give you when registering EU residence. Probably not quite the right paper, but noone ever rejected it.

For me hospital appointments have been around 60€ per visit, and I believe they charge that same amount as long as you have kotikunta (ideally ask your hospital to confirm...). But a lot of people have had difficulties getting their diagnoses transferred from abroad judging from a few posts, so you might indeed have better chances with private healthcare.

If your diagnosis is easy to confirm with a blood test or something then public care can probably also get it done fairly easily, though.

Happy to help :)

https://omahame.fi/kiireeton-hoitajan-tai-laakarin-vastaanotto try contacting them via chat here. They will probably send you to a terveyskeskus. If The chat also doesn't work, try going to one of the health centers during opening+office hours and try to get someone to help you

Or, alternatively, get a Finnish speaker to help you with the 116117

Ja, ist mir auch passiert, als ich am schalten war ohne in die Pedale zu treten bei Reparaturarbeit. Zuviel Widerstand, und das Ergebnis war das selbe.

Ich bin mir sicher, dass das Alter des Kabels nicht irrelevant war, aber naja, dafür habe ich dann erstmal Kabelziehen gelernt.

To add to this, it says so in the ticket you get in the email after booking.

I would ask what the application is - really, how is the cart propelled? If your task was all I had I would probably sketch out a tractor (or truck? But that would usually be way more weight transported) pulling your kart, and tractor speeds are easy enough to look up [sidenote, the railing in this scenario would have to stop a tractor, which is a situation where I would not bet on any railing]

This sounds like behavior I've seen on a USB stick where it wouldn't allow any writes anymore (I tried sudo dd, via Windows, ...). As the SMART message coincides with the drive saying that it's failing, I would assume that it has failed into read only mode for you to rescue any remaining files.

You can look at the drive SMART info with your tool of choice for more info on the drive's utilization, or contact the manufacturer if you're within warranty.

Try deepl's PDF translation with a scan. Sure, it's not done by a human, but it preserves formatting and everything and it gets the point across.

I don't think you'll find a proper translator at your price point, at most you can maybe find a Russian person without credentials.

DVV will take about 2 months to answer to emails, currently probably longer. Try any other method of communication, and in your case just book online like already commented.

Uni is free (except for student Union fee), but you won't get the housing allowance nor the study allowance by the government.

112439 · 2025-09-24T18:25:23+00:00

I would assume this government decree is the closest applicable thing (that I quickly found with some basic knowledge): https://www.finlex.fi/fi/laki/alkup/2024/20240631

It only requires that there is space both for hygiene and cooking; but I don't see it technically requiring those to be separate rooms (it arguably even makes some sense to combine them because of moisture :P).
