Hello!
What a great project. Is there any chance to still buy PCB's, or is the design open source?

I can't message him, it says "insufficient privileges".

@teus, if you are interested, there is an alternative design that is based of dc42's idea of passive filtering of a high frequency (hardware) PWM. The design contains three independent channels for up to three fans and works for me. It was done using JLCPCB's online design software and can assembled units can be ordered directly from JLCPCB using their SMT service.

Hi all, I'm sorry I have been quite busy for personal reasons. I will try to post all the resources in github and share the link today.

Best regards.

Here it is:

Multisim/Ultiboard files, GERBERS, schematic and build instructions.

I will add further info when possible.

great, thank you!
what version of Ultiboard do you use?

hi @Egon-Net, I was wondering if there was a way to purchase two preassembled boards?

S1lencer

Hi, i have 6 preassembled boards left over from my last Batch.
They are from Egons gerber Files and work like a charm.
Feel fre to contact me about it.

I don't have any more boards, but you can go with S1lencer ones
