Bixonic - Expandora [traced]

- Solder Soldier
So summing it up, has anyone successfully built an Expandora (ver.1)?!
Are those schems/layouts verified?!

WOW
I could need to build one for a friend in the next weeks - keep us posted of new layouts!
Thank you!

I've just build this pedal.
I used an LDR and an LED instead of using the Sharp opto unit. That was not a very good idea, so I ordered a H11F2 optocoupler. I also discovered that the 2N3703 isn't doing anythng. I assume that it should amplify the signal it gets from IC3?

Does anyone know the difference from the original to the EXP-2001? The 2001 has a drive pot on it.

I have a EXp-2001, and i open it up to see what is inside.caspercody wrote:Does anyone know the difference from the original to the EXP-2001? The 2001 has a drive pot on it.
The IC is not a 308, it 's a tlo72
i can put pics here if needed.
I should also receive the schamtics soon.

Thanks! Would love to see pictures, and the schematic.

Any news on the 2001 schematic, or pictures?

Thanks! Has anyone made it, to verify it is correct?

Wouldn't that be a TL071?

Hi
What is the CI noted in Figure 5, I want to try this pattern.
Thanks

But my poor english would say: IC noted 5 in the schematic
Sorry

Almost finished with mine. I found a direct cross reference to the Toshiba RN2206 transistor used to sink the current through the opto. The NTE2370 even has the correct internal bias resistors and specs so it should work perfectly. I found Newark and Moyer Electronics stock the part but am still looking to see if Mouser has a direct cross reference in a different brand.Renegadrian wrote:So summing it up, has anyone successfully built an Expandora (ver.1)?!
