Centrifuging electrolytic capacitors has an interesting effect on capacitance.

Discovered your channel while researching how to repair an old tube record player. Love your channel btw. You kind of look like Mark Hamil from Star Wars. That could be a cool Halloween costume idea maybe?

[@TannerTech]

Thanks! Hopefully you got your record player working. I have never heard that before, but being Luke Skywalker for Halloween would be fun!

[@nachom1971]

Cool experiment. I wonder if nasa or the big aerospace companies ever considered this. BTW those sandals on the background look comfy 😊

[@TannerTech]

Haha, thanks! I am sure the big aerospace companies have already solved this problem. temperature is probably a bigger problem up there than external forces.

[@longdongsilver4719]

Are you working at Eppendorf? That old 5417 and the eppis... So nice.

[@LutzSchafer]

Well Tanner all nice and good but what about repeatability precision of your measurement? Actually you are just using this tester which is not a clr meter. Also it uses a 12 bit ADC from the atmel processor and algorithms that at best give you an approximation. You surely show a nice way of learning and understanding basic statistics. Unfortunately they might be flawed by the imprecise measurement. Nonetheless, it makes sense that the capacity increases following a decrease as the "jelly roll" gets compressed and later on resumes it's relaxed state. However the capacitance is defined by the thickness of the AL2O3 layer which is constant. The only thing changing is the distribution of the electrolyte. This should have a higher impact on the internal series resistance than the capacitance. But then again your measurement seems dodgy to me. Nice job nonetheless. I see you are on the right path becoming a scientist :)

[@Basement-Science]

The capacitance on electrolytics probably changes based on a ton of parameters - for example temperature. Just squeezing the case a bit probably does too.

[@TannerTech]

I agree

[@lasersbee]

Was there an actual purpose for the tests or just curiousity ?

[@bios546]

Imagine a tumbling satellite during the no comms time right after ejecting it from the rocket. This might give an insight, but of course such things would be tested. Although, I doubt such caps would because maybe the space grade caps would have to undergo such tests prior delivery maybe?

[@lasersbee]

@@bios546 Can't quite imagine a satellite tumbling during the no comms time right after ejecting it from the rocket... at 14,000 RPM..

[@TommyBoy7Heads]

Fun stuff! Perhaps some blocking could be inserted into the tapered portion the the plastic capsule to prevent the cap from getting wedged down in there. The other variable would be temperature of the cap before vs after centrifuge. Lastly you could try an entirely different experiment with readings in real time in which you place a capacitor inside a cylinder and watch the measurements as you increase air pressure. Or a similar test over temperature ranges. The live readings may be interesting to watch.

[@germimonte]

I don't think the data is statistically significant to derive any conclusion, maybe with better capacitance tests over a broader frequency range? and a way to test them while centrifuging?

[@TannerTech]

I definitely agree with that conclusion. If I have more time, I will do more tests with this. I also think it would be good to invest in a more precision capacitor tester.

[@ElectroRestore]

In your experiment, did you use caps from the same manufacturer? Secondly, were they quality capacitor companies like Illinois or Nichicon? Or were they cheaper imports like ChemCam or no name caps?

[@TannerTech]

The capacitors were from multiple different off-brand manufacturers.

[@phonotical]

How the heck did you work out your p value?

[@TannerTech]

A function in google sheets

[@111000100101001]

Interesting. Could the capacitor’s L/d ratio change how it is affected by a given g field? Got me thinking about caps used for rockets and space travel :)

[@TannerTech]

I know! It would be cool to talk to an EE that works for NASA or SpaceX about this

[@Scyth3934]

Where'd you get that centrifuge?

[@Aditya-mj1kh]

👁️👄👁️ wowiiiii

[@winstonsmith478]

Very interesting. BTW, I think you could do a great impression of Chris on Family Guy.

[@TannerTech]

Haha, thanks!

[@phonotical]

That was a very quick tester! Are the capacitors a 20% tolerance? Maybe if you tried a very old wax sealed capacitor? Did the worn out sandals need to make an appearance 😂🤢

[@TannerTech]

I didn't notice the old sandals until during editing. That would be cool to test an old wax capacitor though

[@phonotical]

@@TannerTech 😂

[@jimcatanzaro7808]

I did some research and testing after you put a capacitor in circuit and use it for about 50- 100 hours the cap will be about 10-5 percent off it just needs time to brake in this topic is also discussed on many data sheets
