Thank you.
Im working now on using a teensy with dedicated laser module. So I can have the mouse and any key/additional macro/button on the mouse, as many as I want in whatever configuraration I need. Google ADNS-9800 Laser Motion Sensor.
Also, im gonna get rid of scroll wheel, I have a working teensy prototype that scrolls using capacitative touch, I have it configured with 3 speed per direction, a total of 6 touch areas. - inspired by frankstripod on hackaday
With a teensy/arduino and dedicated laser module there is no limit on what can be done
The moment I have the laser sensor and im done modelling the new shell I will post a video.
Took me about 3 days to rough model/3d print few shells til I got it right. No scanning, no photogrammetry. I understand not everyone can doit so Im gonna help you guys, im gonna post my model. Most people that need custom hardware, have issues using a regular mice, usually a medical issue so I will try my best to help.
Unless your right hand is exactly same size as mine you will need to resize the model to match. If your middle finger is between 6cm and 8cm long, this model is for you, all you need now is, buy the parts, dissasemble a cheap mouse and hot glue/fit the electronics, reroute switches.
The hard part for people that will need to resize it, is to keep the switches and scroll/bearings "container" the same so its still assemblable
After I finished the model I 3dprinted a few for my buddies. All I need is a piece of paper, a4, with the outlines of the hand drawn on it so I can compare with the model and resize accordingly, longer fingers, wider hand palm, etc.
I dont machine parts at all, in my opinion, polymorphic plastic is best/cheap/clean at learning organic modelling without looking at your hand every time you move a vertice, but im gonna share my model so 80% of the work is done.
