How to connect mouse encoder to 74HC165

[spongebob]

Long searched, but has found nothing on a subject

show the connection scheme please

I think that the scheme should be about such as on a picture

That looks about right to me.

If you want to check it, maybe see if you can find schems for the other DIY encoders, like rasteri's or sashas. I would assume that you've found the other threads about mouse encoders already, and they didn't have any schems? It would be cool if you could tag them all, so that those threads lead to your answer :)

may be this scheme will work?

plz, help, i'm newbie :)

I think the best thing to do here, is to get the parts, and breadboard it up.

I have connected encoder according to the scheme in the second drawing and began to receive such signals from a kernel:

first scheme are work

second scheme will damage photo-transistor

nominal of resistors: 510 Ohm (for diode), 10 kOhm (for transistor)
