I was able to get the pcb for the keyboard done, so I can now start working on the case. I am leaving the other boards modular so that I can replace them individually when I let the magic smoke out.
coming back to the design, I realized that putting all the logic into the one micro controller was a bit above my head. Then I got the idea to augment my skills using fiverr where I met a nice Kenyan man who seemed affordable. After some discussion and many compromises later, I got a $600...
These are all great suggestions! Thank you! I got some phone net adapters, and have plenty of computers, but I am short on keyboards and mice currently. Hopefully I can score another wombat or similar soon because I don't think I will have my keyboard I am working on anywhere near done in...
I need to add the polyfuses yet, but here is what I have so far. I think I have it right, but the power circuit on the right should let the pi pico know which program to run. So long as this schematic works, I should be able to do whatever I need in software.
To free up the the GPIO pins, I...
This is very helpful!
I am inexperienced when it comes to pcb design and have been mostly a high-powered diy guy. I was planning on just sending the 5 volt straight in, but mentioning the polyfuses makes me think that may be a bad idea. How do I figure out how bad of an idea that is before...
Using the CH334U that @cheesestraws mentioned I think will work with some modification to my plans.
The Pico will be bus powered and all buses use 5 volt. What I will do is use diodes so each bus can power the Pico, but it won't back-feed into the other outputs. I will use two GPIO pins to...
This does look very straight forward!
When it is in ADB mode, I will need to have the USB port on the pico read the USB devices, where as when it is in USB mode I will need to have it be a HID device. Depending on how cheap these are, I may just make two separate USB circuits and depending on...
I have done some more tinkering and learning about custom keyboards. To start I wanted to come up with a requirement list.
USB Mouse Input
ADB Output for Mac SE to B&W PowerMac G3
USB Output
RJ9 Output for Mac 128k to Mac Plus
Start button for ADB and USB needs to be on the keyboard

I am getting ready for an old school network party for my employees at the end of the year. I am finding myself in a pinch point I have not experienced before - I do not have enough keyboards and mice. I do have two Wombats, and I love them. This got me thinking though, it would be cool to...
