Keyboard conversion custom case

#1 Post by Kagor » Fri Jun 15, 2018 3:49 pm

Hi!

I love the 7 row Thinkpad keyboard and have some spare parts left from laptops I want to use.

This desktop, USB variant of the keyboard is nice to have but expensive.

I wonder if anyone has tried to build this or some other laptop spare part keyboard into a custom case. 3d-printing can be used.

I see no issues with the mechanical parts, however, I want to know what needs to be done electronically. Converting the pin connector to a USB is one thing. What about firmwar? New circuit board needed? Would this project be too complex ?

It's already been done: https://hackaday.com/2014/04/30/using-a ... -over-usb/

The base circuit is usually a microcontroller board like a Teensy or Arduino. There's existing firmware for creating custom keyboards.

Thanks for the link.

the video guide is no longer active and the keyboard in the pictures is the older model.
is there a guide and a mod for the keyboard model which can be found in the Thinkpad T400, T410, T420 and others?

The guy who made that video later made this https://www.tindie.com/products/rampadc ... eceptacle/, but it's no longer available.

Here's the project logs for that build: https://flashandrc.wordpress.com/catego ... -keyboard/
