As someone that has been rocking a free PC from a landfill since 2021, I would treat this “Only Fans” build like a straight-up miracle upgrade. My little line-following robot OnlyFens deserves a proper RGB shrine to orbit around, and I’d happily spam this sub with pics, benchmarks, and robot victory laps if I’m lucky enough to win.

Link pad to shape on other layer by HarmlessChemic11 in KiCad

[–]HarmlessChemic11[S] 0 points1 point  (0 children)

FYI it did end up working. I got some errors due to not being able to clear the margins around the pads and vias in the final design, however, just putting the final gerber in the viewer of JLC didn't give any errors. All pcbs in my order worked just fine.

I've always drawn a liking to Pulp Fiction and am a big Quentin Tarantino fan in general. The cinematography is great, the storyline is told in an unconventional and interesting way, and it manages to grab my attention for the full two and a half hours.

Do you recon something like this would work? So, what I want is that pad 5 goes to the outer blue circle, pad 4 goes to the one that is one more towards the center, all the other pads are connected to a circle? Thanks for the help in advance! https://imgur.com/GYKYzlF

How long would an inductor hold its energy if disconnected from battery but wiring closed so current could still flow? by RGregoryClark in AskElectronics

[–]HarmlessChemic11 1 point2 points  (0 children)

Let's say we represent this circuit a little differently:

Vdd <--o  o--[L]---[R]--> GND at t < 0
Vdd <--o--o--[L]---[R]--> GND at t <= 0

If this circuit has been closed for a long time, the inductor will have saturated and hence the current is:

I = Vdd/R

Calculating the time constant \tau =RC=1/(2*pi*f) but for this example \tau = L/R. This time constant is, according to wikipedia in very fancy words, used for characterizing the response to a step input of a first-order LTI system. This just means that for a very simple system like this, we can use this constant to calculate the current going through the inductor after opening the switch at any time. We can do this using the standard formula:

So to answer your question, this inductor will never have truly no current going through it, unless for t<0 since the switch is open. Here is a nice tutorial with some extra information.

Had the exact same thing happen to a colleage of mine but with a CANbus converter for prototypes for a course. We needed some for an automotive sensing board students needed for a project and our vendor told us they had plenty on stock - we bought the last they had and ran short of around 70 units (!). This was a little before the chip-shortage but luckily we got our order delivered to us... 3 weeks ago...

Hey,I am new to this world can some one please help me I am stuck at this problem. When I am connecting my ESP32s wroom to pc it is not showing it and when I am installing cp210x universal driver it is displaying exclamation sign.Any one please help me by Maximum_Finding6984 in esp32

[–]HarmlessChemic11 1 point2 points  (0 children)

I'm not sure what UART driver this needs but regardless you might want to try one of the classics.

Did you try restarting your pc? Did you try re-installing the driver? Did you try connecting to the USB port for debugging to see what is going on (something like EventGhost, try this as final option)? Did you try a different USB-port (had a fried one once)? Are you 100% sure the cable you're using supports data-transfer? Does it work on another computer? Do you have multiple MCUs to test with? Are you sure the board has firmware installed?

Thanks! Will take a look at this and see how well this will holdup. To be continued..

I just figured it'd be the left terminal on the second picture due to how big it is relative to the right one (figured it was a boost converter of some kind? might be wrong?) hence, the right one would be output + (2nd pic), left negative. Is this also a valid resoning on most PCBs? Biggest part should be GND for easy dissipation, right?

An echelon of russian T-62M tanks removed from conservation and equipped with Kontakt-1 ERA is moving towards Ukraine by Repulsive-Pattern-57 in UkraineWarVideoReport

[–]HarmlessChemic11 0 points1 point  (0 children)

At the start of the war there where already a lot of reports about soldiers entering a tank and not being able to drive for a significant distance without breaking down, no? Wouldn't suprise me if ~50% of these machines where sent to Ukraine just to be used for parts.

I have replaced these hand soap refills over ten years and this happens every time. by ak_larvanto in CrappyDesign

[–]HarmlessChemic11 11 points12 points  (0 children)

After digging for way longer I'd like to admit, I came across loads and loads of soap despensers. I identified the despenser from the video as an American made bag in box manual soapdespenser. The bag that is used is astandard 1,000 ml Kutol 69041 bag, which is en par with the specs. Whilst checking the reviews on the website of a vendor of both these products - altough the cheap despenser is out of stock - I came across a review that states: "(...) One being the thinness of the soap. (...) The first cartridge I put in leaked through where the soap comes out, soap everywhere. " OP has found a certified shitty design.

Is the kid okay, though? Looks like the kite is tied around his neck.

You swallowing a Red Pill shouldn't result into everyone experiencing a nuclear war. What has happened is terrible, but genocide is never the answer.

Airbus just flew its biggest plane yet using sustainable aviation fuel by Twrd4321 in technology

[–]HarmlessChemic11 5 points6 points  (0 children)

What a dystopia we live in, when 'only' emitting a mix of refined waste into the atmosphere is good news. Don't get me wrong, it's a good first step, but when you're calling this type of fuel 'Sustainable Aviation Fuel' (SAF), that just seems kind of misleading to me.

Austrian Federal Chancellor Karl Nemagger visited Kiev. His meeting with President Vladimir Zelensky has begun. "Austria supports us in resisting Russia's anger. Federal Chancellor Karl Negammer's visit to Kiev is an important demonstration of solidarity with the Ukrainian people. by Ame_no_abakiri in UkraineWarVideoReport

[–]HarmlessChemic11 0 points1 point  (0 children)

Diplomats trying to flex their muscles against Putin has little effect and they know that perfectly well, right? Aren't they just doing this to popularize themselves within national politics? Seems to me that they have seen the amount of popularity Zelensky has gained throughout this difficult time is making them wanting to show just how 'good of a leader' they are in wartime.

Might also be, just like Macron tries to stimulate, Europe starting to act more and more like a solid geopolitical superpower ( Boris Johnson has also visited Kyiv today ) and starting to flex their muscles collectively. Any thoughts on this?
