Is there an existing project to convert a USB keyboard/mouse to PS/2?

Like, I've got a USB KVM, and I'd love to plug an old computer into it, one that's pre-USB.

(this is a thing that's annoying to google)

There are probably similar ones using Arduinos.

This would entirely depend on the code license. But that seem like a nice tool.

Links! What are they good for?

The DNA Lounge calendar pages have hyperlinks upon the artists' names, linking to their World Wide Web Home Pages. Over 10K of them.

Why? Why do I bother doing this? I think I'm going to stop.

Keep the feature for those who care and filter out the walled gardens?

And files ready to upload on a RP2040.
Next easier instructions to build one and better PCBs.

I appear to have rudimentary USB MIDI Device support now on my PicoDexed :)

(I added SysEx the other day too, which I think is largely working...)

@diyelectromusic
I just added SYSEX configuration to my midi router https://github.com/bjonnh/dinoctopus/blob/main/src/pico/midi/midirouter.cpp

that way it passes packets by default or enter sysex mode and gather the full message. I am not sure what happens if things are not in order so I may have to make my own sysex parser with a buffer and a pass through.

@diyelectromusic
Same here take what you need. I was thinking using webmidi to configure it.

For the design I removed the display entirely for now I want to make an external display I can move across devices and talking with sysexes or serial. (more about that to come)

Ever wondered how semiconductors REALLY work?

Once you have been through that, why not design and get your first chip produced?
