I'm trying to build an optical sensor like the one Ultimarc describes here:
http://www.ultimarc.com/optipac4.html.
However, I cannot find the specific optical switch he recommends. There seems to be no Fairchild retailers in my local area (SE Michigan).
On the other hand, I did find this one:
http://www.nteinc.com/specs/3100to3199/pdf/nte3100.pdf from NTE which I can buy from my local mom-&-pop electronics store.
Does enyone know if this one would work?
Thanks.
By the way, how do I make a hot link to a website on a word without the url showing in the post?
