Built a looper today!

[SpufuZ]

Hello,
I just finished this little looper with mix/blend function, based on the "B-blender" i found on the net.
Its really nice to be alble to mix down the delay level and get a NICE transparacy at the same time!
Anyone else who has build anything with the "blender" circuit?

Where's the schematic? Sounds cool!!! Any chance of some sound samples?

[SpufuZ]

heres the schematic!

yeah i could get you some samples!

[Roobin]

Sorry, need some clarification here. Is this a looper as in , play a phrase, store, play it back and play obver the top?

Or is this an FX loop box? I'm guessing the later...

[John Lyons]

Hey, that looks very nice. I was thinking about building that one as well. I'm making the Buff and blend loop right now (which is linked on the same page as the B Blender...)

Did you end up perf boarding it or a PCB? If you have a PCB layout and you don't mind sharing I'd love to get it.

By the way, the Tube screamer sound clip you made sounds great!

yep its a FX-loop not a "rec and play" looper! 

Basicaudio:
Ofcourse i can share the PCB but i dont know really how to export it to you!
What program do you use because if you have a good one i could download it and use it myself, and quickly make a PCB for you.
The files i get when i save in the program is ".dip".
The program i use is called "PCB Layout". And i would rather use something better if i just could find one!

I use Express PCB. It's free and there are ways around the fact that you can't print form the program... You just print the screen shot and them save it to whatever program you want to print from.

If you can just save the looper file as a Jpg or gif file I can resize it if need be. If for some reason you can save the file as such, just  make it big on the screen and press your screen print button and paste it to a graphics program to see if that works.

Let me know what you find out.

You can email me a basicaudiowv AT earthlink DOT net

Thanks

heres the PCB!
First one is with silklayer so you can view the components better.
The screenshots are taken att zoom 400% so you SHOULD get the right dimensions simply by reducing to 25% of origin picture right?

[John Lyons]

THanks a lot Spufuz.
I'll have to try try this one. The PCB looks great!

John

[SpufuZ]

youre welcome!
I suppose i could have made it a little smaller, and less spacing between components, but its actually just a "prototype" pcb.

Isn't it possible to incorporate this circuit into an effect circuit such as a Compressor,
ala the Tone Bender???

[SpufuZ]

i cant se why not.

You can use a PDF print driver and photoshop to get PCB layouts from ExpressPCB, heres some instructions I've been finding useful:

Once you figure your way around the PDF print driver and photoshop, it becomes really easy.

Nice link AdamB, I'll have to study that one.
This is the one I had been looking to for advise http://www.robotroom.com/PCB.html

OMG that PCB looks terrible!!

OMG that PCB looks terrible!!

Any chance you (or someone else) could post a cleaned up version?  I've been wanting to build a Blender-type pedal for a while and am waiting for the right PCB.  I definitely don't do well designing my own.

you´ve got my PCB for the Blender above! The two pictures!
