Merializer,
This is kind of off topic, but I wanted to contact you via your most recent post.  I have watched all your videos and see that you have updated your dowel keyboard and plantagraph mouse box model as seen here:  
https://www.youtube.com/watch?v=jT8-UOCnAnUI think you do fascinating work.  And I am in dire need of a device like yours.  I gather you are in the Netherlands, which may complicate things, but if you are no longer using your older model as shown in the video above, I was wondering if I could buy it from you?.  If not, could you make me one of your recent models?  I will pay for all materials and labor.  And if you are out of the US, then it would require international shipping charges as well.  Are you willing to do this?  
I am so sick from using the computer, and have sustained so many injuries from it, that  if I continue to use it, I am going to have heart damage.   I especially need to get my hand off the mouse, but you cannot do much on the computer without a mouse.  I currently use a track pad, which I have found is the lowest EMF, but I am still getting hand and arm injuries from it.
Let me know.  You can email me privately is you want at superdrove@yahoo.com
Thanks
