New Effect: Payback

[TheAttackman]

sorry to be a pain.. but i read through everything and i cant tell exactally which layouts are confirmed
could someone help me out

thanks

Hello everyone,

I posted a new effect called Payback at the site. It is a looping sampler with a host of features. There is article explaining it's operation and several modification suggestions.

Enjoy.

Oh and about that little challenge:




how can i disable multiple recording on paybackv1?

thanks





Happy Canada Day to all my fellow Canadians. Happy 4th of July to all my brothers and sisters to the south as well.

Your Tone God,

When I'm back on a pc, not iPhone, I'll look up the schem, but if i remember correctly, it really is as simple as tying the address pins to ground.

thanks a lot , don't forget

Yep. All the loop number switch does is set the address pins to the right value for roughly half the memory location to start from. Setting them all to ground starts from the beginning.

a2,a3,a5,a8 pins directly to ground right? it will give me 60 sec loop? my english not good , i did'nt understand well , sorry.

and, do you have verified pcb layout for v.1? i saw very tight pcb layout for v1 in earlier posts. is it verified?

thanks a lot

Yes connect all the address pins (A0-A9) to ground.

I don't have a verified PCB layout myself but there ones out there.

Good luck!

thanks, i found this layout

it seems right to me what do you think?

Hi all!
I am trying to figure out how to build the Payback v1.1
I am a bit confused,
is there a verified list of links with:

• the PCB
  the list of materials
  wiring diagram
  basic instructions and notes

Thanks!

I do not know of a verified layout. The DIP version of the ISD1600 was short lived so not many people got to build it so there really is not a demand for a layout.

HI!

i've been getting ready to build either V1 or V1.1..first shot will be v1, since i got 2 ISD2560s
the problem is, i bought a while ago on ebay, can't return, and they look dogdy (or they have started to do so ),
compared to some pics i've seen working in circuits (which i found half a year AFTER buying, when i got some spare time) - those apparently working ICs had white markings and a small, deep dent near pin 1, as well as two shallow dents,

     would anyone care to comment on these?? greatly appreciated...  (i still don't have the circuit board to test them doh..)
  did i get duped? 



the other one has the two dents, but both are missing the pin1 one.

-- also, i've read as much about paybacks as there is on the net, but still have a question for any of you master (or god) circuiteers :
     How is the pause between loops noticable in v1.1 compared to v1 (or to the zvex lflj), if the Rosc is set to 100k (v1.1)?

many thanks!

[duck_arse]

both of those pictured have the pin 1 id. it is the big dent at the "I" end of "ISD". more dents don't more identify. and if I was paying 15$ us or au for a chip, especially a cmos one (and these are cmos ones), I'd have it in conductive foam. wrapped in tinfoil at the very least, but never, never, NEVER in white, static-making polystyrene foam. not ever.

can't help with the circuit workings.

[edit: ] oh, and hello, welcome to the forum.

[armdnrdy]

I purchased a SMD ISD1620BYS-NO IC from Digi-Key for a future build. (Payback V1.1)

It came on conductive foam, in an ESD blue bag, enclosed inside of a moisture barrier/ESD bag, with a silicon packet, and a humidity indicator card which reads "Bake parts if 60% is NOT blue"

These ICs might be sensitive. It is probably not a good idea to play tackle football with your kids with one of these in your shirt pocket during a lightning storm.  

[duck_arse]

ANY 15$ ic is sensitive.

[jernop]

Yea, my thoughts too, when i opened the package and saw the IC in styrofoam   i would have never store it like THAT, but since it is, i though maybe leave it be, not touch too much, not rub it against anything, until i have to install it in the socket...  



i ment the dent in direct vicinity of pin 1, like in the pic (these are the ones i saw in a working circuit):

[armdnrdy]

My IC has the same wave running through the ISD logo as the images you just posted.

[haveyouseenhim]

I hate to throw the F word around, but jernop's ICs look like they were resurfaced and lasered.

[jernop]

it's those paralell lines right? 
ratz.
i'll test them in the "typical application" from the data sheet anyway, to make sure ... should be merciful with my time..
