It would be funny if there was a community effort to make a schematic of the Neutron or Proton, design a board, and have it manufactured at JLCPCB or wherever. Sell it as a kit with all the SMD components already populated, all you have to do is solder in the through-hole jacks and pots and whatever. Use a Eurorack module form factor so it doesn't need an enclosure. Sell it at cost, which would probably be way less t…
Why on earth would someone go thru the effort to sell it at cost thought ? Also you underestimate economies of scale behringer can employ, I'd be surprised if you could get close to their price. You can look at various DIY stuff and you will probably notice that getting stuff DIY isn't all that much cheaper I'll throw you an example: Maths, which Behringer cloned, costs ~$300 fully assembled Befaco Rampage, which is…
Behringer has impressive scale, but honestly I think for PCB manufacture and assembly, JLCPCB probably has them beat -- and any random hobbyist has access to JLCPCB.
The cost of Maths and Rampage has more to do with having to earn enough to pay all their employees and make a decent profit that the actual marginal cost of manufacturing one more module. Maths is very popular, but it's still a fairly low-volume market.
I think one thing it would be hard to compete with Behringer on is enclosures. But maybe that doesn't matter; a Neutron/Proton clone wouldn't necessarily need one if it's a Eurorack module.
