That was me, it was a printed stepped resistor, thin glass board the gold plated contacts overprinted with resistive film. However it would now be very easy and economical to do it with a printed optical grey code position sensor with 6 bits (f1.2 to f45 in 1/6th f-stops). -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
