My university used Artemis to do basically what you’re describing. Files are uploaded via git. But it seems like selfhosting would be a lot of work.

Ask Electronics@discuss.tchncs.de•this thing look burned to you?English
5·2 months agoHard to tell, a couple of the other components also look dirty. Are they just dusty, or is there some residue from a blown-up part?
What device are we looking at? I’m guessing some kind of power supply? What is the failure mode You’re trying to fix?

bike wrench@lemmy.world•Bike repair stand recommendations?
1·2 months agoI’ve been very happy with my Feedback Sports Pro Mechanic repair stand. It’s not the cheapest, but we’ll worth it. Very stable and the ratcheting clamp makes adjusting for different tube sizes very easy.

29·5 months agoHe proposes the cloud be owned by communities, so in a way by everyone. That’s not the same everything being owned by private companies.
I mean, I don’t like AI. But leaving in debugging messages can easily happen without AI, too.
I think most of us are pretty damn average.
That’s true. Like, by definition.
This seems to be an engineering sample CPU. Since these are pre-production, that could mean it’s basically a fully functional CPU. It could also have serious issues.
You can use most of the connectors you would use for bigger wires. Wago lever nuts are rated for conductors as small as 0.14 mm².
If you want something to fit a din rail, standard terminal blocks (something like this) should also work.

Ask Electronics@discuss.tchncs.de•How come there are components in TO220 packages that supposedly take 100A given their small legs?English
0·8 months agoFrom the IRF1404Z data sheet:
Calculated continuous current based on maximum allowable junction temperature. Bond wire current limit is 120A. Note that current limitations arising from heating of the device leads may occur with some lead mounting arrangements.
You need to design the PCB so that the heat from the legs can be properly dissipated, or they won’t live up to the rated current.
Also, traces on a PCB are much thinner than those legs. A trace with the same cross-sectional area would be impractically wide.

Unfortunately, SawStart is one-use-only. Once started, the blade cannot be stopped, and must be replaced with a fresh blade while the running one is carefully disposed of.

Advent Of Code@programming.dev•why should we sort 2024-day1 ?
3·9 months agoIt doesn’t ask you to subtract the numbers, but to calculate the distance (i.e. the absolute value of the subtraction). So depending on which numbers are paired up, the sign of the pair can be different.

The zoo takes special care to keep kings separated from opposite-color pieces as part of their conservation program to prevent mating in captivity.

bike wrench@lemmy.world•Something is bent, but what bending causes this?
4·1 year agoEvery single freewheel does this, and it’s not an issue.
The freewheel bearings don’t line up exactly with the wheel bearings. This is always the case to some degree, because the interface between freewheel and hub is a non-precision thread.
It might look weird when freewheeling, but once you put use the pedals, freewheel and hub are rotating together, negating this wobble.

Ask Electronics@discuss.tchncs.de•Whats the best website to get Electronic components for small projects in Europe/Germany?English
2·1 year agoIf you can wait a couple weeks, AliExpress is going to be the cheapest.
eBay may be a bit more expensive, but it’s often my go-to because you can find everything and usually there are options with short shipping times.
For not too obscure parts, I would look at Reichelt, their prices are surprisingly low (especially if you bundle your orders to save on shipping costs).
Can you get a big flathead screwdriver in there to carefully knock it out? It should allow you to get a better angle than the dedicated tool.
Go slowly and alternate the places you’re putting the end of the screw driver. You want to push the cup out evenly, or it will jam and possibly deform the head tube.
HiPER Calc Pro. A great scientific calculator I use constantly. (There is also a unpaid, ad-supported version, and the ads weren’t too intrusive the last time I tried it)

Ask Electronics@discuss.tchncs.de•Want input on optimal PSU fan placementEnglish
2·1 year agoThat’s probably not a bad idea, although I doubt it will make much of a difference. But since you’re redesigning the whole thing, might as well do it.











Windows has that button, but only if you right-click the drive in file explorer and select “eject”. The dialog is very similar, but has the option to continue anyways. That option doesn’t appear when ejecting from the taskbar.
Which is weird, because it means that Microsoft went out of their way to make two different, almost identical dialogs. And they made the better one harder to reach.
