Quick question... would a PI-Zero core be possible? ...not a cpu-taxing application by a long shotI have developed a web interface for my big preamplifier.
The web interface runs on a Raspberry Pi Zero.
The Pi is electrically isolated from the preamplifier controller.
The web interface operates bidirectionally, meaning the status updates on the web interface even when adjustments are made directly on the preamplifier using a rotary encoder or IR remote control.
Here's a sneak peek.
Is there interest in using this as a controller update for the Muses from the thread?
Hello Daniel, I would be interested in the web interface. As I am currently rebuilding my preamplifier. I have a question, can you also use a 3 or 4 Raspi instead of the raspberry Pi Zero, I still have one.
Yes shure.
We only need a new controller pcb, new controller and a uart connection between the controller and raspberry pi.
I use a zero, because the Zero is tiny and need less power than the bigger models.

Currently, it's only running in my big preamp. That's a completely different project.
I would need to adapt it, meaning design a new controller board, adjust the firmware, and modify the software for the web interface.
Additionally, I would need to provide documentation on how to set up the Raspberry Pi.
That was the reason for asking for interest in the community.

Unfortunately, I am not familiar with the software. Is it possible to loop the encoder pulses and Ir remote control signals through a Zero and pass them on to the current controller board?
Hello,
I have completed the control board and wanted to test it,
X3 pin 1+ and 2, 15 volts supplied, output measured 3.3 volts.
Encoder and IR sensor connected, 50 cm cable each and
LED connected.
Encoder pressed then power switched on the led does not flash.
What am I doing wrong?
Ps. The circuit boards are from 07/21 from the AAA forum, unfortunately I only have time to assemble them now.
The controller has been soldered by a professional, the rest I have built.
Greetings Dirk

Maybe a defective controller, wrong encoder switch connection, bad soldering.
Connect only the switch and try it again.
Connect only the switch and try it again.
I have now soldered the encoder directly and checked the controller, no error found, no flashing of the LED.
Controller Alps STEC11B03 encoder, 15 pulses / 30 detents, vertical.
I have checked the LED, it lights up.
Can I check whether the controller is faulty?
If the controller is defective, you still have 2 controller boards for sale.

Do you hold the button pressed during the power-up process?
Have you ever connected the Muses Board?
Does it work.
Yes, I have a few boards and controllers left.

I press and hold the button when switching on.
I haven't connected a Muse board yet, I'm still missing the 100 Ohm resistors, wrong delivery.
I won't be able to check the Muse boards for about 2 weeks, so I'll get back to you about the controller boards.
Thanks for the help

Hello Meldano,
I have assembled and tested the volume controller with the mainboard. The controller does not work.
Do you still have two controller boards for sale?
I hope I didn't kill the Muse chip during testing because it only got -15 volts and I had a cable break in the positive line. And the Muse controller got about 40 °C hot.

Hi Daniel
I'm very interested in this web interface for the Muses Volume . Are there any news about the progress?
And do I see it right, that the two controller boards won't work in parallel (remote control and web interface)?
Or could remote control be realized with the standard features of the RPI PI (USB Dongle RC)?
Thank you very much for your great contributions.
Best regards, Bruno

Hi Bruno,
Sorry, I have too many other projects at the moment.
Additionally, the response was not high enough.
