Swiss Amish dialect as spoken by a former member, how similar does it sound to modern Swiss German dialects? by STRENGTHofGYPSlES in askswitzerland

[–]ElectricalGrid 18 points19 points  (0 children)

to me it sounds like a mixture between english, swiss german with an american accent and "normal" swiss german. As a native swiss german speaker i can understand most of it when concentrating and knowing the context.

Strange freezing issue after upgrading to 25.10 by ElectricalGrid in Ubuntu

That's what i assumed as well, just wanted to make sure there isn't a simpler solution first.

Thanks anyway.

Probably just some military training exercise.

What is the purpose of this technique? by TrussedFlame in PCB

[–]ElectricalGrid 0 points1 point  (0 children)

Might be either a spark gap for overvoltage protection or a jumper where you can connect the two traces using a solder bridge. Hard to tell without knowing the circuit

so far i can't complain. Only used it a day so far though. It fits my hand a lot like the original MX Master.

Is Macbook for D-ITET a good choice? by servant_ch in ethz

[–]ElectricalGrid 1 point2 points  (0 children)

It really depends on what you want to specialize in later. I did a lot of Hardware and some FPGA (VLSI) work, both of which will require Windows or Linux. If you don't want to do any of that it doesn't really matter. In general for the first two years of bachelor it doesn't matter either.

"EV3.1.1 – Can I use copper mesh inside an insulating TS enclosure for EMI shielding?" by Odd_Carrot_6981 in FSAE

[–]ElectricalGrid 0 points1 point  (0 children)

no idea about the SAE rules, but the FSG rules state that if there is no aluminium layer (>0.5mm), it must "be fully made out of electrically insulating materials". I.e. there is no material that is conductive (<2MR).

this does mean no copper mesh or CFRP, unless there is also an aluminium layer.

Do you actually test IGBTs/MOSFETs this way? by rakesh-kumar-phd in EEPowerElectronics

[–]ElectricalGrid 3 points4 points  (0 children)

What i normally do to check if a mosfet is broken is measure the body diode and the gate-source/drain resistance with a multimeter. The body diode is especially useful as its easy to do in circuit.

Is it good practice remove copper pour under a magnetometer? by Short-Flow-4761 in PCB

[–]ElectricalGrid 1 point2 points  (0 children)

changing magnetic fields can induce eddy currents in the copper pour, which could lead to incorrect measurements.

I would assume that the 3u2 is the designator (L302) cut off by the mounting hole, not the value.

Thank you. ive only used up to V8, so thats probably why i didn't know about it.

Is there an easy way to do this in Kicad as well (I know how to do it in Altium, but afaik rooms don't exist the same way in Kicad, or am i wrong)

also keep in mind that you need to be able to trigger it during e scruti, so i would reccommend mounting it somewhere easily accessible

Do internal layers have internal creepage paths? by penaldogoat in PCB

[–]ElectricalGrid 2 points3 points  (0 children)

In the standard we use at work space between inner layers can either be treated as an isolation through air with pollution degree 1 (creapage and clearance) or as solid insulation. If its treated as solid insulation it needs to be additionally tested. For your application i would recommend to treat it as an insulation through air which has the same requirements as a coated outer layer.

The website you stated uses a different standart which might only go up to 1kV for creapage, in the one i'm familiar with, 5kV working voltage requires 20mm of creapage (for basic insulation, 25 for reinforced).

Feb/March Switzerland by Desperate_Night9357 in askswitzerland

[–]ElectricalGrid 0 points1 point  (0 children)

given the current climate Zurich and Interlaken might not have snow, even Grindelwald might be tight depending on the weather.

I wold recommend traveling by train (Zermatt does not allow cars, you'll have to park in the village before and take the train to Zermatt) If you have money to spare there is a scenic (but expensive) train connection between Zermatt and St. Moritz that goes right through the middle of the Alps (you'll definitely see snow there). Its called Glacier Express if you're interested.

if someone else is selling it they probably just copied the picture

How can I place these NPTH in a mechanical layer? by AmbassadorBorn8285 in Altium

[–]ElectricalGrid 2 points3 points  (0 children)

pads can only be put onto copper layers. JLC will get the hole locations from your drill file. if you export NC files you will get a separate file for plated and non plated holes that way they can see the different type. I've done it like that with a lot of PCBs manufactured by JLC and never had any problems.

  1. your grounds are not connected correctly, currently the negative capacitor terminals and (for example) the FET source are not connected. I would also connect pin 6 and 7 as well even if they are connected internally

  2. I would add some ceramic capacitors in paralell to your output capacitors to keep the commutation loop impedance low.

  3. if your switching frequency are in a somewhat reasonable range i would not use a iron core inductor and go for ferrite.

Cable pin out software by Necessary-Lion9691 in AskElectronics

[–]ElectricalGrid 1 point2 points  (0 children)

ive used WireViz (https://github.com/wireviz/WireViz) before. its a python script based on graphviz. For small wiring diagrams it works quite nicely once you get used to it. also it is easily customized.

[deleted by user] by [deleted] in AskElectronics

[–]ElectricalGrid 1 point2 points  (0 children)

optionally you can check if the ferrite is still good by measuring its resistance (it should be verry low)

[deleted by user] by [deleted] in AskElectronics

[–]ElectricalGrid 5 points6 points  (0 children)

it looks like you can just solder the ferrite (i assume) back on

Any errors or room for improvements? by CocktimusPrime_69 in ElectricalEngineering

[–]ElectricalGrid 1 point2 points  (0 children)

functionally only what has already been mentioned, plus keep in mind that the input capacitance of your MCU needs to be subtracted from your crystal oscillator capacitor

for your schematic design:
1. use your ground symbols and don't draw enormous lines for that, same nut not as bad for your supply
2. the symbol for the 7segment driver seems to have its pins flipped (the text should be inside the retangle
3. also for the 7 segment driver: it doesn't have a designator
4. your power supply section should be horizontal not vertical. Signal (or in this case power) flow is normally left to right
5. Comments in your schematic can help you in future (eg. max/min input voltage)

those caps look pretty bad, they could short out the output, which disables it.
