[ORDER] ARP Odyssey Mk II/III VCO PCBs/Panels

Post by frequencycentral » Wed Aug 15, 2012 4:39 am

Ok, I'm ready to take orders for this project. Please make your payments by Paypal gift to:

rickholt22@hotmail.com

Please state your MW name, what you are ordering and your address.

I've made a bunch of PCBs already, but still have the bulk to go, so shipping might be a few weeks for tail-end-charlies!


--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
AndyR1960 @ electro-music.com has kindly given his permission for me to do a run of PCBs based on his work for the ARP Odyssey Mk II/III VCO.

Here's the EM thread: http://electro-music.com/forum/viewtopi ... 395#367395

Each PCB will be £15 GBP including shipping. Here's my PCBs:

Here's my proposed panel layout for 2 x VCO:

Image

...which is 21HP. Panel will be £20. It includes a sync switch as well as additional socket for ring mod. Ring mod will be on a small daughter board, and will be included free for anyone ordering 2 x VCO PCBs.

Any interest? I'm going to build one (or two) before I do a run to ensure there are no issues, but Andy has already built a number of these.

How important is the 2N5910? Seems everything else is easy enough to find.

I recon i'd order eight VCO pcbs and four RM pcbs.

Any idea on time frame?

I'm just waiting for parts then I'll build, making my panel today. So if all goes well maybe a week or so. I'm going to socket the trannies and see if they can be viably subbed with something more common.

as far as I can remember they can be substituted with 2N3906.

I found my 2N5910 on ebay some time ago...

Cheers

Will it be hard to add a range switch like on the 2600 so they can also act as LFOs?

You should be able to just normalise one of the CV inputs to -ve, that's simpler than adding a switch.

But if I wanted to add a switch? Pretty hard?

Also, will there be a silkscreen on the pcb, or are these hand etched?

Easy. Just hook up a switch between the CV input bus and -ve.

Hand etched as in the photo above.

Hi Rick,

I'm interested in 2 VCO PCBs and 1 Ringmod PCB.

I might get a set if it happens before the Hearn Morley VCO, I really just need a couple of VCOs.

Yeah, this will happen before the HMVCO1c. It's basically ready to go right now.

Hmm, do you think the HMVCO1c is far off? I wish I could do both but I can't atm, and the HMVCO1c seems to be more of an all-rounder workhorse.

Duuuuuuuuuuuude I'm trying not to spend any more money!

I'm in for 2. Maybe more, been wanting some Odyssey VCO's for a long time now.

Also, while I can appreciate the rough and ready etched boards I can't help but wish you'd start getting them made with at least a silkscreen, it makes the build process easier imo :)

.. I'm still going to build most of your stuff anyway tho :tu:

you could try doing what i do in these cases
simply print the component layout with a bubble jet printer on normal paper [ note: do not use a laser printer the laquer will make it run ]
and apply it using circuit board laquer, spray the board apply paper
line it up as best you can with the aid of a very bright light shining through the board and spray again over the top then let dry for a few hours
punch through all the holes with a needle or a sharp scriber from the component side and then populate the board
works quite well.
I might take a couple of boards have to see how bad my finances are first though
It probably wont happen today but if it does it definitely wont go smoothly.

Actually, I had another look at the build docs and spoke to Andy, there are pads on the PCB to add a VCO/LFO switch and a 270K resistor to -ve to provide the -ve reference. So it's all there, though I'm still going to go the normalised socket route.

Here's my panel:

I would be interested in 2x VCO and 1x RM PCBs. No panel thanks. Oh and I'd group them with the VCDCO from electric Druid when that's ready to save some shipping :)

^^^ Gotcha.

I just finished a revised layout for the RM, based on Andy's layout but shrunked down a bit. It's so small that I'm throwing it in free for anyone ordering 2 x VCO PCBs

Wow - fantastic, Rick :tu:
I'd like to change my order from 2 x VCO + 1 x RM
to
4 x VCO + 2 x RM

Thanks a lot!
