Fiberoptic mouse with quadrature encoders and custom shutter buttons--- make money online

hey guys then here this is a fiber-optic

mouse that is similar to another project

that I showed on YouTube the fiber-optic

joystick so it's a standard computer

mouse that does not contain any

electronics or any wire at all actually

all of these are fiber optics and it

senses the direction through a

quadrature method and uses the existing

encoder wheels so as you can see it has

two optical channels per encoder wheel

and they are offset by 90 degrees and

phase so as the mouse is moved and the

wheels turn by sensing which phase leads

the other the direction and speed of the

of each axis can be sensed so on the

receiver side I'm using this

telecommunications fiber-optic to

connect the mouse to the receiver and

I'm using these are just standard s T

connectors s T fiber optic connectors

and what I did to mount the fiber optics

in the mouse was just to remove the

ceramic ferrule from the SD connector

that's actually easier than it sounds

you can just put a grinding wheel in a

dremel and the ceramic comes right out

so on the receiver side I'm using a vago

HF be our series transmitters and

receivers and the transmitters are just

on all the time just to supply a steady

source of light and the receivers are

wired to a microcontroller that does the

quadrature decoding and the cable itself

is a 12 conductor sixty two point five

micron multimode connector and its uses

one of these MPO Multi multi channel

connectors so you can just pull this

apart and connect all 12 channels

actually what is this look like in the

camera can you see the infrared coming

out there maybe so it looks faintly red

to the eye can actually see it even

though most of it is in the

infrared spectrum so the one thing that

I did new on this different from the

joystick was I added buttons so these

are just standard you know they're the

existing mouse buttons from the original

Mouse and what I did was I opened up the

buttons and added a little shutter so

that when the button is actuated it

actually blocks the little shutter

blocks the light going through this hole

here so what I did is I mounted the

fiber optics in the button body and then

when the shutter comes down it blocks

the white from one fiber optic to the

next so that was a little difficult to

build these but they are actually quite

reliable I've clicked these a bunch of

times and it's it's working just fine so

I hope you liked that project and I will
