Anyone have 500 rack module designs?

[matmonster58]

I just picked up a 500 rack on a whim and don't have anything to put in it. Does any one have any fun module pcbs or gerber files? I'm really just looking to build a few simple modules so that my new purchase isn't collecting dust.

I think Ill make a simple 312 or that1512 based preamp to start out. It should be a simple design that I can knock out somewhat quickly and come back to later down the line.

I also want to make a "pedal patch" module so that I can easily use my pedals for mixing. A basic reamp, DI, and 9v power supply on one card would be nice to have and easy to design.

I plan to build some much nicer modules down the line but I just don't have the time or budget right this moment. I have a bunch of other projects to wrap up and I'm busy finishing up my degree. I'm just wanting to get some hands on experience with 500 modules before I start investing more. A lot of the old 500 projects floating around seem to be outdated and no longer supported.

I’ve got nothing for you, but if you end up building something, please post it! I’d be very interested to hear about it.

Link audio makes a lot of cool SSL kits and 500 rack power supply kits. I use an ssl eq plug-in all the time so Ill probably end up building one.
AML makes mostly neve style kits

I also want to add:

stay at home type 69 project

I don't know I haven't completed mine yet, but I'm pretty sure there are no regulators or diodes on the pcbs' because they are NOT 500 series, therefore why would they be needed. You could put them in any case that they would fit. You need a 24v PSU, the pcb is just the single circuit board for...

This is one of the only open source 500 preamp projects I've found that is still alive. Most of the projects I find are from 15 years ago and full of dead links.
