Sasha Posted March 16, 2006 Report Share Posted March 16, 2006 Has anibody tried to make encoder out of mouse parts. I am gathering mouse parts (optical elements and weels) for long time for rigid optical encoder. Idea is surely not mine and seams very easy to make it if you know how. What do I need to use IR phototransistors as an encoder. It must be some simple circuit. IR diode is probably just conected to the power source. Almost all of my encoders on Korg microControl stopped working properly short after I bought it (new) and I almost didn`t use it at all. After that I realised that mechanical encoders are really bad idea. Optical is virtualy nendestructible! What do you think...? Quote Link to comment Share on other sites More sharing options...

Davo Posted March 16, 2006 Report Share Posted March 16, 2006 This sort of thing is frequently done by arcade game tinkerers; particularly those who play with MAME. See http://www.mame.net/ Look up "spinner" and "mame" and you should find some howtos. Quote Link to comment Share on other sites More sharing options...

henrygr Posted May 23, 2006 Report Share Posted May 23, 2006 Just a note to ask how your experiment with mouse parts has gone. I had though of using the wheel that triggers the movement when the ball rubs it as a way of measuring the distance an organ drawbar had moved. Time wasn't on my side though, so I thought I might experiment with it a little later in the year.Cheers.M Quote Link to comment Share on other sites More sharing options...
Dano Posted December 25, 2006 Report Share Posted December 25, 2006 This is exactly what I'm doing (trying to do): recycling old logitech mice (model M-M35) to use them as encoders, and with it, build a linear fader. (If I find some motors to recycle, I would even like to make it a motorfader...)I first tried to use the IR phototransistors and LED by themselves, but found out the phototransistors chip works in a mysterious way (seems like it's a powered chip) and I couldn't get it to work by itself with the IR LED. So what I finally did was to power the whole board with 5V and get the signal on two pins of the phototransistor. AND IT WORKS !!.more info on http://www.midibox.org/dokuwiki/doku.php?id=make_encoders_out_of_your_mouse Quote Link to comment Share on other sites More sharing options...
henrygr Posted December 25, 2006 Report Share Posted December 25, 2006 I am a bit lost as to what you did. Are you pointing the IR at a moving object in order to measure its movement? Quote Link to comment Share on other sites More sharing options...
Dano Posted December 25, 2006 Report Share Posted December 25, 2006 I am using the already existing coded wheel of the mouse...Check the (newly added) link in my first post... Quote Link to comment Share on other sites More sharing options...

audiocommander Posted December 27, 2006 Report Share Posted December 27, 2006 more info on http://www.midibox.org/dokuwiki/doku.php?id=make_encoders_out_of_your_mousegreat!thanks for adding this hack... I knew the time would come to use my old ps2 mice :)cheers,Michael Quote Link to comment Share on other sites More sharing options...
henrygr Posted December 27, 2006 Report Share Posted December 27, 2006 This is super stuff. Will pull a mouse apart and see what I can come up with.I assume you are using rotary encoder source code at the PIC end? Quote Link to comment Share on other sites More sharing options...
Dano Posted December 28, 2006 Report Share Posted December 28, 2006 Yes, I've used the midibox16e code "as is" and it worked. I then started to customize it a little because I'd like to make a linear fader out of the encoder and so I had to change the speed... But that's out of topic...
