you have up and down choice on yours !
what are your schem plz
here’s this one i used
Glide / Slew : there is a difference ?

thx !
I will follow your construction carefully, I’m curious to hear it

A double sub oscillator, a potentiometer and the sockets still have to be wired and the panel is still made of cardboard, was only to test whether everything fits. Made from plexi glass today.
And a tuner with an Arduino Nano that Sam had posted somewhere. 2 sockets, LEDs and the 7 segment display will still be soldered today.

Rungling workkkkssss!!
It definitely alters the Rolls sounds.
If anyone is following my progress with the 2-Roll, you know it makes basic pulse noises… well… this is something else!

It was a bit of a fiddle to get everything connected, but I got it working in the end:
The displays are stand alone voltmeters, and they are supposed to work from [edit] 4.5 -30 Volts. Measuring the 5 Volt supply however didn’t work properly as the display showed some erratic behaviour.
By default they have 2 wires so they get their power from the source you are measuring the voltage of. After some research I found that that on the small pcb they have some wire bridges you can break and then add a third wire. By this you separate the power supply from the input to the measuring circuitry. If you then power it at 12 V via the ‘power’-wire it is possible to measure voltages lower than 5 V using the actual input wire. Nice !

dude - that is absolutely awesome!
I want one lololol

If you look for Mini Digital Voltmeter LED Display Volt Meter on aliexpress.com, you will find examples like this:
for less than 2 USD a piece.
Mine are of type DSN-DVM-368 v3.01
They are described in detail here ( use google translate if your Dutch is a litlle rusty):

20 $ us for the pcb .
there is a lot going on in this module
LED Voltage Level Meter Totally cool looking.
Two 3 input DC voltage mixers with offset adjust and normal and inverted outputs.
Linear Lag Processor (long and short time select).
RC Lag Processor (long and short time select).
buying pcb would probably be the easiest way to go , but if you enjoy a challenge …

now I see what you were saying just use the voltage meter circuit . still would be nice to have all those functions , maybe replace the led’s with the numerical display ?

You can get cheap digital panel meters off ebay/aliexpress/banggood/etc (ideally get the ones with three wires), but a numeric display is kind of missing the point of the MFOS voltmeter, which shows you both level and range:
(voltmeter demo starts at 6:00)

This picture shows the wire bridges on the pcb of the standalone voltmeter.
The input and power supply are now connected (bottom left).
If you cut them apart, and connect a wire to the left pad, you can use that to measure low votages and use the other for powering the device.
I use them to check the power supply voltages, not to visualize modulation of signals. The arduino oscilloscope I wrote about is better suited for that purpose.
