Rate or speed led indicator in Neovibe

[Mich P]

Hello !
Does anyone know how to make it ?
Thanks

No one ?

Can't say that I do but it is something that I would really like to see... I'm close to building one but that is a feature that I love about my Fulltone Vibe (which I'll sell if the Neovibe works out).

So, I'd love to see any responses to this.

You should be able to add another LDR under the shield as a current limiter for your rate indicator led.

I think I did that but it turned off the lamp and the led turned on and was blinking.

I used the method described at the link below. Seemed to work just fine for me. Info is about half way down the page.

Using an LED/resistor in series with the bulb is OK as long as you get an LED that works OK on nearly the same current as the LFO bulb. If the bulb needs more current than the LED can stand, you'll smoke it. The LED/resistor is OK for a rough and ready approach. It either features or suffers from, depending on your viewpoint, fading out with low intensity.

I think another follower could be hooked onto the LFO to be independent of the intensity control. That would take a transistor and a resistor in addition to what's there already and would be independent of the intensity control, which is my preference.

Thank you everybody

here is my indicator implemented in R.G's schematics. works well.



I picked a green 2mA diode and 150 ohm resistor in parallel ( blue 10-20mA LED and 330 ohms resistor), but a trimmer is THE solution.

Excellent yeeshkul
thanks a lot

It's sound cool RG
A little schematic maybe ?
Thanks answering anyway !!
