pHotoNviBE

[Jiuk]

This is my version of PhotonVibe. It tooks a few months for getting all components. It wasn't easy but I really hope to get good Vibe pedal.

Build advice
- Must be space betweend LDR and lamp. Univibe's LDR located on PCB. I prefer this way.
- Do not change value of LED protect resistor.
- Cap is not must item. I made a cap for lamp and LDR but don't use it anymore.
- It has 3 trimpots - mix, offset & osc. gain. Check my trimpot setting. I tried to found out best sound to my ears.
- Use more than 100mA power supply. This time, I'm using 7660SCPA chip for charpump and it works well, but this will change to LT1054 chip.

Nice build!

(Don’t change the charge pump to an LT1054, it will not work as pins 1 and 8 are connected on the PCB, 1054s don’t work that way )

Yo, do the photo resistors need to face the LED?

I built an Abyss and kept them flat.

Good looking build!

Nice !! One of my favorite PedalPCB circuits ...

OF course, pin1 will remove.

OF course, pin1 will remove.

I think you will have to cut the PCB Trace between Pin 1 & Pin 8 if you want the use the LT1054.

why swap to the LT1054 if it is working with the other charge pump?
