usb interface

open note to tommy tyler,
i was just ordering parts for the usb interface--my first.
mouser has raised the price of the idc connector to .83 from .67-- makes the total 4.07 + shipping.
also wondered if we could save .03 by using the same vishay resistor for r1,r2,r3 in 1% 10k?
also am wondering what you thot of using cat-5 cable for the remote in place of phone cable?
the catalog pages for catalog #619 are 561,537,486,396,392,unlisted,734,865,1154 for version 2.0, 6/10/2004.
i was going to order four 802300 chips from delcom and then sell the extras on the market place forum for $8 + shipping to avoid the $5 handling fee at delcom---do you think this is an ok idea?
thanks, jon

Cat5, sure, the data rate is sliw enough.

Buying parts and reselling them, sure, why not.

No problem with 1% resistors if they're not too large to fit where you want them to. No performance problem with ANY kind of cable, but I recommend you not use anything with solid conductors. A cable like this that gets a lot of flexing should use stranded wire, so it doesn't some day break silently and secretly and cause you grief.

thanks classicsat
and thanks to tommy for the reminder to use stranded cable.
