Cynthia Breaksdown Vactrols

[AlainHubert]

Vactrol is actually an optoisolator/optocoupler trademark name belonging to the PerkinElmer Optoelectronics company, who has been making them for over twenty years.

Good stuff!! Outstanding presented!

Thanks for the very entertaining and informative demonstration Cynthiia !

THANK YOU! I have never heard anyone explain anything so well! You should teach! Thanks alot.

@loschaofedmaro the most common use for an Optocoupler isolator in my experience is a to reduce noise for an analog application actually. There is no need for lots of names it is a LED + detector. Done.

[Renzothedestroyer]

What does this mean when a manufacturer is talking about Vactrol Filters? Also, is it ever used as a stabilization method for oscillators?

I don't know what I am talking about of course, but that last question randomly came up in a conversation, so I was curious.

[drwho9437]

That is because everyone calls them optocouplers / optoisolators now...

[loschaofedmaro]

@drwho9437 Actually; an Optocoupler or Isolator is almost digital device they have a very small analog range, these are analog and non linear.

Thanks for the project. Vactrol was originally a brand name, and the two main types either had a photo resistor like the one above, or 3 leads coming out the back which were like 2 ends of a potentiometer and the 3rd lead was like the wiper. They were also pretty slow. How would I make one of these second type of vactol?

Thanks

HiBright red LEDs are good too with the LDR.

I was always wondering what a vactrol was. They are used in my modular synth. Thanks

why are you so girly?

[PilferMusic]

Thanks for the info... one good thing about loosing my hair and shaving my head is I no longer have bangs to bug me like that! :)

[yermyahu]

Thank you, that was very helpful Cynthia. I've questioned that myself - what the HELL is a Vactrol?

[bassface17]

Cynthia talks like a dude.

[WendyStringer48088]

@bassface17 Some women sound like that.

[electricrainbowness]

awesome awesome awesome Cynthia!

thanks so much!

Before ever hearing of such things, I discovered, like usual by accident, that the remote control receiver on a television set can be used as a photosensitive resistor. I have to agree, they are the most fun resistor to play with.

[chloroxjello]

Cynthia rules. Any noise projects?

[strength2in3numbers4]

Cynthia = fuck yeah.

[DANNY2188]

does someone say "fuckin quintron" lol the drum buddy is all powerfull

[HLSDK]
