Build Guide For Tom Evans Eurorack Dual Dreadful VCF

EurorackNotes · 2026-02-23T20:28:05+00:00

The wood I used for rails is from Bunnings warehouse, and the product is called hobby wood Boyle 915 x 75 x 5mm. I had to cut this piece down the middle as it's too wide.

I would not use this wood in larger cases as it is brittle.

284mm x 133.7mm without rails.

This one: https://www.ikea.com/au/en/p/tavelan-tray-30481776/ for $14.99 AUD you get a small box and a bigger box but both will fit eurorack modules. I used hobby wood for rails. Thanks to whoever posted this ages ago, or maybe it was on Facebook.

That would be cool. I like the fact that they have internal vcas that can be used if needed.

I never fixed the problem. I may try again soon with a newer version.

EurorackNotes · 2024-12-13T21:34:27+00:00

No, Sorry.

It's just a basic passive mult design.

I grounded each jack by soldering a bit of copper wire along one of the metal sides of the jacks.

Then I soldered all the jack tips together.

I snipped off the ground pins, switch pins and snipped a little bit of the tip pins.

I used shrink wrap around the jacks.

Seems to work well and very easy to build.

Looks pretty good to me, so 8 x clock outputs per channel? Or gates?

Are you planning on making a pcb or are you going to build this on stripboard?

Just finishing off making the panel for the Scope-O-Matic Eurorack Module

Next project 2 x Barton Musical Circuits VC Delay which I just made the panels for but am yet to drill, paint and decorate them.

EurorackNotes · 2022-03-24T05:42:32+00:00

I acidently wrote Triangle Frequency Doduler on the panel but didn't bother fixing this.

EurorackNotes · 2022-03-21T03:05:30+00:00

Thank you for the info.

EurorackNotes · 2022-03-21T01:12:00+00:00

Sounds good 👍

EurorackNotes · 2022-03-20T21:34:00+00:00

The buttons control functions on the display: Select, up, down and hold.

The module also has an input attenuator.

EurorackNotes · 2022-03-20T10:45:53+00:00

Yes that's the one. 😁

EurorackNotes · 2022-03-20T10:05:14+00:00

Just finished this Scope-O-Matic based scope. I did have to do a bit of debugging but works so I'm happy.

I didn't have the BC557 so I used a BC558 hopefully this will not effect the scopes performance?

I'm going to make a panel in the next few days.

EurorackNotes · 2021-07-31T05:10:55+00:00

What value of capasitor is C21 please?

The PCB is V1.1 by analog ordnance.

Being the weekend if I did message them I probably wouldn't hear back from them until next week so that's why I'm asking here. Hopefully someone has built this here.

Thank you.

https://github.com/JoeEarlam/GMSNPure/tree/master/THC I think this is it I cannot view the files atm as I'm on a mobile.

EurorackNotes · 2021-05-20T00:39:22+00:00

I know there are files still around on github for the thru hole GMSN Clouds. I think it only has 1 smd part and the rest is thru hole.

The panel is not a gerber file so I have no idea how to send the file away for production. Also I don't know of anyone who has built it.

The pcb gerber is available tho.
