There's a 3D printed base with some logic to turn it into a regular USB keyboard, are there any for T6x keyboard assemblies? I have a bunch of NMB keyboard so it'd be nice to make usage of some of them

weird photo editing on the esc key in the top-down views. seems like someone's custom-one off?

I know people have done some mods for the keyboards in a similar fashion, so I was hoping an actual production of 3D printed chassis were made now, along with (more importantly) the electronics.

I can't find anything about "HISTUDIO DESIGN", so no idea who the original person that made that, was. I don't believe the ebay lister made it.

Those pics are partly (or all) photoshopped.
Esc/1 on the first and last pic definitely is.
The trackpoint is also a fake.
The base might be real...

Here's a USB keyboard adapter for the T60 with an even more ridiculous price: https://www.etsy.com/listing/1747143493 ... dapter-for

That person on etsy is nuts! You can get an old controller made with a Teensy for ~$40 cdn.

I know right? An RPi Pico is what, 5 USD?

Frank Adams (thedalles77) has a Pico-based design on Github, but cautions that it's an untested prototype.

Has anyone ever reverse-engineered the usb controller in the SK-8855

Is there a need to? The Arduino/Teensy/Pico-based controllers probably only need a bit of modification (in software) to support the T410/420 keyboard.

I figured that the LITEON controller would be easier since you wouldn't need an SBC, just a chip.

So you manage to figure out the inner working of the Liteon chip. Then what? How would you replicate its functions? Fabricate your own chip? How much would that cost?

One more thing, you don't need an SBC (single board computer) but a microcontroller, which Arduinos, Teensies and Picos are.

IMO the SK-8855 is inferior to the T60 NMB keyboard assemblies, which is why it would be more advantageous for a nice solution to pop them in something to use.

So the 3D print does actually exist and it is real. Photo editing on the ebay listing is just a red herring as I thought.

It's a real shame there's none for the T60.
