Pulleys

[Jackpilot]

Any good source for small pulleys, bushings,bearings, etc ( US or Canada) for my throttle mechanism.??

[autocadplease]

I have had luck buying stuff on Ebay (R/C parts are cheap). Also, Princess Auto in Canada always has cheap items.
I have also stolen some of my kids Lego and K'Nex gears and pulleys! Please don't tell them!

If the plastic gears inside an old VCR that you've gutted won't suffice...Find a few old power tools. Cordless drills where the battery is completely shot or jigsaws that lost their jig would be a good source of some sturdy metal gears.
(I like to tear things apart after I've worn them out...)

Or you can use optical encoders or LVTDs direct.

For bearings, you can't go past VXB. They've got bearings down to 1mm internal diameter and they're pretty cheap price-wise. Also try SDP-SI for that kind of products.

Very interesting,

How do you interface an LVTD?

[cscotthendry]

It looks like that LVDT gives a varaible DC voltage output, so I would guess that anything that can be used to interface a potentiometer could be used to read one of those LVDTs
