Last week my Filco Majestouch-2 Tenkeyless (with Cherry MX Blues) arrived, and I was really happy about it...
There was only one minor thing about it: The cable!
So I decided to turn my new keyboard into a wireless one.
First I examined if my favourite Wireless Keyboard Controller board (Logitech Wii) would fit, and which batteries I would need, then I started my mod.
It's really simple, and not very much work (although it seems a lot of work).

This is what you need:
- Filco Majestouch-2 Tenkeyless keyboard.
- Logitech keyboard for Wii.
This keyboard contains a really ideal wireless keyboard controller:
2.4 GHz (very responsive, no latency like the old 27Mhz ones)
very small (so it will fit in almost any keyboard)
also tenkeyful-support
low power consumption (my previously modded keyboard's AAA batteries still last after 636 days of intensive usage)
easily solderable
cheap (I bought some for only EUR 8,50 (=12 bucks))
- Duracell 9V battery (contains 6 AAAA cells, we only need 2 of them)
Due to the keyboard's compactness there's not much space left, AAA batteries won't fit, that's why I chose AAAA batteries.
With its 500 mAh I think these batteries will last for at least one year or so.
- Some small wires
- Rosin core solder

Tools required:
- Soldering iron
- Desoldering pump

This is how I did it:

1. Removed old matrix (desoldering pump required).

2. Added new matrix

3. Opened 9V battery

(contains 6 concatenated AAAA cells, which is ideal for soldering)

4. Watch the polarity. It's different than it seems. The flat end is positive, the tip is negative!

5. Added wireless controllerboard & batteries.

6. Finished!

Great first post, welkom op deskthority!

Nice wiring. Is the new controller NKRO and problem free?

ok thanx... 6 key rollover (sometimes less than 6)... but 100% problem-free at normal usage...

Wow, that's really cool. Unfortunately I lack the soldering skills and/or time to practice to do this. Question that immediately comes to mind: does typing feel the same with the switches held only by the metal plate and no PCB?

Typing feels the same, but if you watch accurately, you can see that the keys are a little wobblier.
And if you want to pull out a keycap, you're probably pulling out the switch too...
