DIY looper schematic?

[Bigwan]

Hi all,

I'm wondering if anyone here has ever found something like this online?

Lookin for something very similar to the wobo double looper:

I work for an electronics company so lots of the stuff for it would be knocking about our lab and anything else will probably be knocking about my garage! Just don't have the time to sit down and design one myself!

Cheers

Without a doubt the best DIY looper around.....

here's a diagram I got from the guy at singlecoil.com

that little orange thing is a resistor Im not quite sure on what kind of resistor it is but Ill post back when I find out

Thanks mate! That's all I need actually. I was originally looking for a powered relay type looper, but this'll do the job perfectly! Cheers again.

You can use the diagram above with relays too. Just use a 3PDT relay in place of the stomp switches and use seprate SPDT to switch the power to the relay coils. Use a DPDT if you want a second LED to indicate ON/OFF at remotely-located switches.

a 510 ohm resistor is what you should use for the standard (non-bright) led's and if you want your led brighter, you would use a smaller resister

You could perform a calculation to figure out the resistor needed, based on the LED's specs, and the power supply.

R = (V-L)/I

Where
R is the resistance of the resistor (Ohms)
V is the voltage of the supply/battery (Volts)
L is the voltage rating of the LED (Volts)
I is the current rating of the LED (Amperes)

the ratings for the LED should be available from a datasheet on the suppliers website, or at the store. Just ask the guys at the electronics store you get it from, where you can get a datasheet for the LEDs.

Hey, where do you guys get the boxes for these?

hammond makes really great enclosures and are used by a ton of pedal manufacturers.

you can check out some of their stuff here

the 1590bb is the one used alot of times but for the looper im building Im going to use the 1411t which is here on their website...just search for the model number in google and you'll be able to find a distributer

Thank you for the formula.

Sorry to bring back an older thread. To wire the switches per the diagram, shouldn't the blades of the 3DPT be horizontal? So the holes in the lugs face down, at least I think, I don't have it here in front of me. Thanks

Not in my experience. But it would be wise to double check the switches you're using with a multimeter.

So, IYE, vertical? Hmm, gotta go find the old meter By old, I mean Simpson 260 Thanks!
