Just finished my 3x cv comparator, now on to testing, labeling and decorating the housing. Just a helpful hint when building, the patchbay header should be adjusted for vertical height as well before final soldering. The pins are long so you have lots of play.

Darn, I already ordered from thonk twice, didn't want to take a chance on the 5k diff. They are sending my stuff tomorrow, will try to ask them about adding these.

With a few people, the mail service was really slow.
But the packages did arrive , if not very overdue.
(with the exception of one, for now)

If any of you did not get the kit / pcb yet, please contact me

There is only one thing I want for people; to have fun with this module!

Hi!

Can I use sn74hc14 instead of the cd74hc14?

The first one I have laying around for some reason the other one I need to order if the first one is no good! :)

Thank you for a nice build guide btw! :D

Hi, so I finally got around to building this (V2) and it rocks! Thanks FetidEye.

In case anyone's interested here's pictures of the PCB and you can see some simple mods I did for my convenience and use case. The mods are:

- 100k pots for CV amount instead of voltage dividers R17,R18 / R19,R20 / R21,R22 (the third CV pot isn't installed yet) (this way the 3trins is unprotected I know, but I use the comparator with 3trins-internal signals and non-modular audio so voltages are pretty low)
- alternative 2.54mm header inputs for CV inputs (for 3trins convenience)
- switch for combining inputs (not sure if this is the same mod like someone further up in this thread did before, it is a simple on/off/on switch that sends input 1 > 2 or input 2 > 3 if required
