Roland 100m 140 ADSR layout

Post by frequencycentral »

Update 10/07/12:

Here's the build doc for the updated layout. Spacing included for both 9mm and 16mm pots, as well as optional slow/fast timing caps.

Original opening post:

It could really do with a second set of eyes before it's built and verified. I have perfed this circuit a number of times before (though using a different layout), so I know it to work with the semis I've specified.

Probably so! I've matched the tranny numbers to the Roland schemo, though not the other stuff.

Jolly good! Think I'll etch some as well, seems like a nice project (not that there's any shortage of those :hihi: ).

Nice work! :party:

Great, it would be helpful to me if you could let me know if I've left enough space around the power headers, as this is my first foray into Euro sized modules.

it'll probably hang over the edge of the board a little bit, but that's not a big problem. maybe i'll leave the board a bit larger. main thing is to keep the board under 110mm if you want to mount it vertically. what's the spacing of the pots?

not sure how many you have to go around, or what you want for them, but I am interested in 2.

PCB dimensions are 71mm x 54mm. Pot lugs 2 are 18mm apart. I'm using 16mm Alpha pots.

I've got a few spare PCBs but can pretty much etch whatever people want. If you would like any PCBs, the cost is £12 GBP per unit including shipping to anywhere. Payments by Paypal gift to:

rickholt22 AT hotmail DOT com

Please include your wiggler name, full address and number of PCBs you require in your Paypal transaction.

Will you still be offering these PCBs in a few weeks?

Not sure but assume so. My system is +/-15v, so I can't test them on +/-12v until I invest in a Doepfer supply and bus. My instinct says yes it will though.

This looks like an ace project! Judging by the he pot spacing, the PCB looks like it would fit Euro/3U better than MOTM/5U. If true, I wonder if it would be too rude to ask if you'd be able to etch on a slightly larger board so I could drill mounting holes for my 5U.

Well done for making such an awesome project! :hail:

OK, LectroiD has asked for a slightly different layout, so I'm going to mod the existing layout to accomodate pot spacing of 1.625” for 5U. The actual component layout won't change, I'll just tweak the pots part of the layout. Anyone else interested in this? Any other suggestions for 5U format? Maybe a 5U pin header too? What's the standard for that?

Just wondering, did you manage to get an etch of the 5U yet? I sent a payment over last week, just wondered if you'd managed to get anything etched. No rush if not ;)
