Any of the pots that are voltage dividers should be able to be any value you care to use. Lower than 100K will consume a bit more current overall, but I don't have any reason to expect that would be a problem.


Thank you!

Always late to the party. If anyone has any spare 555-VCO PCBs gathering dust I would love to purchase them and give them a good home.

The building notes says:

2)
when powering from 12V:
R13 = 2k
R27 = 22k
R33 = 137k

I don't have any 137k Sad . Can i keep the 100k instead? Or would it be better to take an 120k or 150k (wich i have lying around) to get even closer?

Many thanks

the higher R33 the higher the ramp level. i would go for 120k. the 150k would not hurt either.

i don't have any left.
however, you might want to drop thonk an email and just ask him. maybe he is willing to sell just the front panel.

Hi Aurelius, I have a couple 555-VCO panels you can have. My modular is 5U so I don't need them. Send me a PM and we will work out the details.
