Title: My first homemade keyboard - Omron_B3G-S Alps 60%
Post by: domoaligato on Tue, 09 July 2013, 19:34:20

First I would like to thank all the wonderful members here that have answered a lot of my questions while I have been building this.

I built my own keyboard using minimal money.

I bought a few used keyboards from a local pc repair/recycle shop.
I liked the feeling of the one with the amber Omron_B3G-S Alps the most.

So I desoldered all the switches and removed the pcb. then I cut the plate down to 60% size.
poker iso size.

I followed the lowpoly method demonstrated by Matt3o's build log threads for his steelbeauty and brown fox keyboards/ and samwisekoi's GH75 wiki page here http://wiki.geekhack.org/index.php?title=Hard-Wiring_How-To.

this page had the datasheet that unlocked the pinouts for the omron switches for me. (thanks Findecanor)

The Matrix is all wired to a Teensy 2.0 controller using hasu's firmware.
hasu has been very helpful as well in answering my questions to get it setup. Thanks!

I have only one pic for you atm but I will update this with more potato pics soon.

I love the rust on the plate lol.

It is serving it's purpose. to learn hasu's firmware and to develop future firmware related projects.

RALT = FN
FN + / = \
I miss the windows key to open the run menu so maybe I will make FN + R = Run menu

I am still getting used to typing on a custom layout and iso winkeyless

check out hasu's huge readme file for all the crazy stuff you can do.

Oooo, how do the omrons compare to say the Matias Clicky or Clicky White Alps?

I am also curious. How would you describe the Omron switches?

to me they are louder and require more force then white clicky alps.
the board is at work atm but I will take more pics tomorrow and if I can collect enough nickels I will try the ripster nickel weighing test.

I have not tried matias switches yet. btw omrons are a different switch hole cutout from normal alps. but they fit all standard alps keycaps. :D

You should thank Daniel Beardsmore. He has done a great job on the Deskthority Wiki.

I really like the legos or i think that is what the case is made out of lol. I'm working on making a hard wired keyboard as well and only 2 weeks after finding out people were making their own keyboards on this forum lol

Most awesome - great work (even if you think it is only a 'learner' board).
