Echovibe "light box"

I'm wrapping up my echo vibe build right now and was looing at some other companies kits and the original univibes and noticed that they had a little reflective box to go over the photo resistors and bulb.

Do I need to make something like that for mine? Or would being in the dark enclosure be okay?

I was debating on measuring the space and 3d printing a hollow cube to put over them but not sure if that's going to really change the results of this pedal enough!
 
It depends on the brightness of the light bulb and the sensitivity of the LDR's, and how they interact with each other. The reflective box preserves the available light so the LDR's can react to it more easily, but depending on the spec of the LDR, this may not be what you want. You could try to build a reflective box and see if it makes a difference in the sound of your vibe with and without it.
 
Makes total sense! I'll put it together without it and see what it sounds like. Printing a little cube won't take too long anyways! Thanks for the quick reply.

The Angels Vibe kit has a round spot for the cover, I used a plastic cap with some foil tape inside.

Adjusting I did in the dark for max bright at the top and barely visible on the bottom.

I tested with the foil lined cap in place and without (just the back closed,) I perceived slightly faster response of the intensity knob from zero up but no difference in the max setting.

I did have my first 18v bulb burn out after about a year so I had to install these

I would get some extra bulbs if you don't have and install sockets rather than soldering to board.

Sockets also raised the bulb a bit so adjustment of opto's was needed.

I should have mounted the bulb on sockets….i ordered a few extra bulbs too!

I just gotta get the pots and switch’s wired up and it mounted and it will be done!

That was my first vibe pedal and I fell in love with it.
Maybe ready for another.

I really dislike desoldering and getting stuff off the board, hopefully I will get better at it.

Been looking at this one, looks good.
Post some pics and sounds if u can
