ABDUCTOR II DELAY.

[Jdansti]

What is the difference between Abductor 1 and 2?

Abductor 1 has switches to control the 2nd, 3rd, and 4th delays. Abductor 2 gives you more control by having pots on the 2nd, 3rd, and 4th delays to control the mix of each.

I thought that in "Abductor 2" the aliens brought you back home.

^ indeed, they do bring you back , but you cant sit down for a month .

Abductor Delay II Single layer Version 

[matt239]

What would be the easiest/best way to mount the PCB in the box? (the double-sided, Deadastronaut board)

If we use right-angle, PCB-mount pots, will they need to be 9mm, or will 16mm fit?

[deadastronaut]

hi matt, i used 16mm  pots...took the plastic covers off...

you wont get away with right angles as the pads need to be wired to the pots .

the board isnt designed vor board mou nted pots..

rob,

[BoogiemanX]

Nice work maungaja.
Is there a pdf or other printable layout for the single sided PCB?

[deadastronaut]

^ i'm not sure what size enclosure he used for his 1 layer version

we never saw the final build.

the 2 layer pcb fits a 1590bb

Hi Rob,
i'm putting away my boss dd3 for this awesome project... 
I emailed you one month ago through your web site to buy a pcb but you didn't answer me, so i'm trying to replicate
the pcb from the schematic using KiCad on Linux but it's a little bit hard and time consumption. I will try also to add filters to
decrease the noise of PT2399 and i'm also trying to find out if could be possible to add a tap tempo to your delay so i will be
the only one i will use...
If i will success i will post the mod but i'm a little bit rusty in electronics, schematics and so on, so it takes time...
Anyway are your PCB's still available? So i will avoid to draw one by myself...Thanks!

[deadastronaut]

hi guy, sorry man, i must have missed your message..

been getting used to a new tablet etc....

yes i still have pcbs available, no problemo...

ive never messed with a tap tempo, so i dont know the min/ max delay time that they will
do....and actually be in time...i would read up on that before trying it.

No problem Rob! ASAP i will make the order for the PCB. In the meanwhile i'll keep trying to study a
way to add this feature i think it would be very nice...Thanks!

HEADS UP:

a couple of people said they had a lot of hiss with this...

anyway, had a word with mr samhay on here and he suggested this fix..

and its now perfectly quiet...even with headphones on, cheers sam, your a star..

do this and you 'll have a nice quiet delay...

bear in mind your abductor vol level should be at around 10'oclock for usual bypass level.




nice easy fix. 

[balkanizeyou]

Is this fix also possible for Abductor I? Should I just connect pins 5 and 7 of the in/out op-amp, add a 1k resistor from the input cap to pin 5 and increase the 220k resistor adjacent to pin 5? As the Abductor I doesn't have a schematic I'm a bit confused, thanks in advance.

[deadastronaut]

the Abductor I is fine...

you are correct there was never a schemo of it as i took it straight from breadboard
into DILYC...unorthadox i know, but hey it worked...

[balkanizeyou]

cool, I was just wondering if it would improve the performance of Abductor I, but if you're saying it wouldn't then I'm not going to try it.
Thanks for the reply

[deadastronaut]

yeah the abductor I is ok...just been using it...

this was just a heads up for Abductor II...

[Andrew B. Campbell]

I'm having a bit of an issue with my build, unfortunately. I've finished everything, double-checked the solder points, went ahead and applied the modification you had indicated at the  end of the thread here and I can't seem to acquire any audio from the input. I know that the knobs' features work, however I'm not getting any LED indication (the cathodes are both on the square pad, etc...) The only way that I can tell the features work is by flipping the toggle switch back and forth which administers a very, very subtle pop as it's shifting and emits a short, delay signal that I can manipulate with the time knob, LFO and more, but it only lasts for a mere second or two. The more I turn up level two, as well, the more I get a rather harsh, sawtooth synth sound.

Now, the way that I have the ground heading into board is the linked, mono input/output sleeves heading into the ground pad. Aside from that, the input and output are soldered to each of their pads correctly. I'm just not sure where I may have gone wrong with this one:

I'm really not quite sure what to look for here, so any help would be appreciated. I've loved this delay for quite some time and just got back to finishing the build. It may be something relatively simple that I'm disregarding. Here are some photos with indicators to show where the wiring has ended up for certain pads:

[deadastronaut]

hi, you need to swap those mod resistors over....

[Cozybuilder]

That 1K resistor on the solder side looks like 1M

[deadastronaut]

yep...he got them mixed up...weve all done it..
