Vanishing point pots

Bernardduur · March 30, 2006, 02:24:44 PM

I am experimenting a bit with filters (the Super Filter (high pass / low pass / band pass)) is great! I want to add a sequecer, so I found the Vanishing Point.

I can't find any values of the used pots....... Doesn't it matter or is there a fixed value I overlooked.....

Quote from: The ArticleI left some part values off the schematic because it would be hard for me to recommend values in these places. For example the value of the stage pots depends on both the stage LED indicator as well as the LED in the optocoupler. This is something your going to have figure out. Some other values were given a range just as a suggestion.

I usualy find 50K-100K pots work well.

OK, great!

Anyone knows where to buy those small pots??

Are you talking those mini-pots / trimpots like those used in the Zvex sequencer series ? Digikey and Mouser both carry lines of them from various manufactures. The big problem with them is that most of them are log. Most people wire them in reverse to make them more tolerable to adjust.

Ah, OK....... Well, I have a lot of lin 100k pots here, so I just have to use a bigger enclosure

I don't shop Mouser so I don't know on either account. Check their catalog/site.

Mouser is the most confusing website ever. So many choices, so little coherent descriptions.

What measurements should I be looking for?

I hate mouser.

Try maybe 6mm or 9mm pots. Maybe even 12mm.
