Hey, are you still collecting orders? I'd be down for one PCB. Thank you!

I'm new to synths, the 3trins is my first. I don't understand what a comparator does or how it's useful? I see that it adds another layer of permutations but what's happening here?

the comparator compares the input to the HIGH(3v signal) and outputs the result (upper and lower)

the voltage control makes it act like a VCA with (positive) bias control.
you can use all outputs (RGB outs, VID, LFO's) to modulate all inputs of the patchbay and control this with external envelopes and LFO's from your modular synth.

Comparators in video processing are used for keying.

It takes a smooth varying voltage like a grey scale,
compares it to a voltage threshold,
and outputs a hard-edged version of the initial image.

I've just got my 3TrinsRGB+1c Kit from Gieskes this week and am
starting on the build, looking up some info here. Do you have any
boards left?

Hi!
an update: the pcb's have not arrived yet. it might be that they are being held at customs.
Hopefully the package will come soon.

Hi
i've made a panel mockup. (not the final version)
see 1st post attachment for the .ai file (illustrator)

note: i found out that the 3rd potmeter is a bit out of line. (placement error)
so keep that in mind when making your panel! this template is lined out according to the pcb.

if you want to make a box (for lasercutting) see this site:
http://makeabox.io/
I made a enclosure design, also see 1st post attachment
cutfile_box_panel design120x60x25.ai
I'm going to the Fablab soon, so I can share updates / results then.

Hey!

I would like to join for the list to buy this when next run happens, if possible.

Thanks.

I got my 3Trins built this week and I'm amazed at what it can do and the possibilities it opens up. What is the price of a PCB vs. a Kit? I'm still in!!!

My kits arrived today and now that I've seen the enclosure here, I'd love to get the instructions to cut one. Any plans to make them public?

enclosure file

I've designed the box for 3.5mm thick wood.

You can use http://makeabox.io/ to make a custom outline for other types of wood (thicker or thinner wood I mean)
just make sure that the pots and jacks fit :party:

And now I realize the ai was linked in your first post. Helps when I read. ;)

Outstanding. Now I have an excuse to work with my friend's lasercutter.

I'd be interested in a kit, is there still one available when the parts come in?

Does anyone have a recommendation on a module(s) that would interface well with the CV input and be useful with LZX gear? ...the module(s) will be my first euro purchase. I was looking at a simple LFO and envelope generator, just want to make sure I get something that won't be useless when I start throwing LZX into the rack. preferably DIY.

you could use an audio input + envelope follower to let the comparator move on input sounds

LFO's and envelopes are always useful, for audio and video.
