I know I should make a different thread for this but I'd just like to comment that this has been fun. It's just the right amount of smart and stupid that I crave more of in life.

I found the bug above while working on version 2.

Today I managed to get an experiment sorted for the KBD board. The serial terminal is now managed from Core 1 instead of Core 0 like before, the change is significant because Core 0 is required to be the…

Version 1.3.2 released

https://github.com/LimeProgram…apter/releases/tag/v1.3.2

This is a bug fix release. The device would save your settings but not load them. I don't know how this got past my tests but it did.
Sorry about that.

...it's completely out of the Range of my knowledge what you do - but I follow with awe your progress. Thx duncan

I assembled and done some light testing to one unit.
It looks good and what limited functionality I tested, works well!

I am really happy to say that you can access the settings terminal over the usb mini-B port, even windows sets up the correct drivers…

PCB's arrived today!

Still waiting for USB-2-232-KBD PCBs to arrive. The bits of LCSC have arrived at least.
Hopefully I'll have them before the month is out.

The hope is that the USB-2-232 will be rolled into the USB-2-232-KBD. So there is no wasted testing and messing around.
Improving one helps the other.

Handling the tracking on the usb-2-232 was quite the headache, one quick flick left…

Hallo!

It was long put off but I've finally ordered the PCB's from JLC with assembly. I ordered 10 since the price difference between 10 boards and 5 boards wasn't even a 10'er
I've checked and doubled checked and I'm pretty sure my circuit is correct for…

Hallo,
I decided to upload the exp slot cover and DS1287 Hat (renamed to DS128X Hat) to GitHub. Bare minimum upload and I could add pictures and stuff another time, just not in the zone for such things.

…

Hallo!

So I've been trying to make the most out of ordering from JLC and I made two little boards to figure out panelizing.

One board is for mounting a PS/2 port on a serial port mount on my AT case.
The general idea is that the ps/2 port sticks to the PCB…

Wieder Zuwachs im MIDI-Bereich:

Einen SC-88 Pro hatte ich noch nicht, und für 88 € konnte ich nicht widerstehen. Einen SC-55 für 55€ oder einen MT-32 für 32€ hatte der Verkäufer leider nicht im Angebot...

It doesn't have a hub built in but you can connect a hub or a KVM.
I actually don't know how much it would cost to build in a hub but hubs really don't cost that much generally.

Currently with the USB-2-232 it has some handling caked in…

There we go.

Moved some traces around to keep vias away from the silk screen and to try to make them look nice.
The 5v power got itself a nice thicc trace, I don't think it needs it but I think it looks nice.

I also went ahead and renamed the project from…

Alrighty, todays mission is going to be making the back of the board look nicer.
Silkscreen, move traces around to look nicer, teardrops, some filleting maybe.

Outside of the name of the thing, does anyone have a suggestion for something to write into the…

Right so.

I ordered the through hole bits from LCSC plus some extra bits I'd use.

Also put together a BOM and CPL file for JLC, it works out to a nice chunk of cash as well.
Half regret ordering the bits from LCSC now instead of just sticking with a my…

There is one.

F1 on the board. Behind the DIN and above the pin header. The DIN and the Pin header go through the poly fuse to the rest of the system. So it does come before the jumper.
The JLC part number I noted in the schematic is for…

I was asked something on the vogons thread about this, I thought I'd share my answer here as well.

The micro on the pico is part of the pico. You can use it to program the pico or you can use a USB OTG cable to plug in a KB and mouse.

Hallo!

So the trace routing should be done now.

Two holes were added for the sake of a case and J7 labeled "DIN PWR" allows you to power the device from the keyboard port of your PC.
I don't really recommend using it unless you know what you're doing since…

I've started routing the traces. I forgot how slow of a process it was.
Still, getting to a final shape that's more square than the original.
