snow (or not so snowy right now) white north "Canada". I can grab a 4007 near me, so I will try that when it comes time, thanks.

Just a quick update:

After making adjustment to the pcb and checking over it all several times we have finally placed the order with the PCB house for both the HADSR and the noise-lfo-s/h boards!

The boards should be arriving here in a little under 2 weeks and will be shipped out to you guys shortly after!

Thanks for your patience and support!

First post updated.

These are in stock and will be shipping to those who have already paid shortly!

I will keep these in stock for anyone to order.

When I start running low I will update the first post. Otherwise these are available.

Thanks all!

-Mike

UPDATE:


Clean your work benh and heat up those soldering irons!!

All Paid PCB orders have been shipped!! This is fun!


-Mike

p.s. I ordered extras this time, so if you feel 'left out', its not to late to join the solder party! w00t

Hi,

is it possible to use a CD4007 instead of a MC14007? Datasheets look similar.

Can somebody confirm this?

Thanks

Any changes for 12 volt?

Works on 12v as is.

Can anyone confirm that 4069 and 4007 works instead of 14069 and 14007? I am making an order and would can order the "14" versions but rather wouldn't if I can use the CD version as I have some in hand.

Cheers

I used CD4069 ok, used MC14007 though. Actually I will try and do a write up of how I wired this and how to switch between long/short envelopes soon, I've just got to get around to doing the LED indicator.

Cheers

Ok Ill grab the 14007 then just to be sure.

I would love to see how you did it. And ya if you figure out an LED do let us know, that would be a welcome add on.
 

Dego









First I tried ken stones led driver but did not get that to work then I used this from Foniks schematic:
http://electro-music.com/forum/phpbb-files/woollastonadsr_147.gif

And it worked great as a LED driver. I used it directly to the output after discussing that with negativespace. He recommended using a high insensitive LED. Works good.

To mount the electrolytes I put two legs in the same hole for the chosen two electrolytes. Then I leave one leg without soldering it to the pcb on one of the electrolytes. The other electrolyte is mounted as usual. Then I solder the legs of the two electrolytes to the switch and after that I solder the leg of the second electrolyte that is not attached to the pcb with its leg to the switch.

I have built two of them smile

Thanks, I was actually going to try Ken's circuit - I'm surprised it didn't work here. The circuit you posted is pretty similar to how I've done it before so I'll go with that. thumbs up

Cheers
Blair

EDIT: And the cap to switch for envelope length is C35 (6.8uF) - I'm using tantalums as per the original and switching between 2.2uF (short) and 10uF (long).
 

Dego









I used the exact same values for envelope length as you and was happy with the result. 10uF was the choice since I had no 6.8uF at home but I am happy with the result so I will not change it.

I used a dual 1M pot wired in series to get a 2M pot. like this...

So are all of the lugs that are tied together "c"?

If you look at the bottom on the pcb, you'll see that "b" and "c" are already tied together. The pot acts as a variable resistor between pads "a" and "b,c" so you need only hook-up "a" and "b" for it to operate correctly.

I finally powered mine up.
Question. Not sure if this is a fault of my own or part of the design. At the level given, the sustain always... sustains, even if there is no gate/trigger. Its level works fine and it does die when set to 0 though.
It was a quick test, so far the attack and decay work like expected.

Hmm, how is the "HOLD" pot set?

The "HOLD" pot, when triggered by the gate input, will extend the gate for the amount of time set by the pot, even when the input goes low.
