Thanks for the insight.

Getting rid of the CR2032+its holder itself would reduce the weight significantly. Of course, looking at the RTC consumption I could use a much smaller battery with solder tabs. I agree, I would need to redesign the PCB, but a slimmer, longer board with the pic right at the very opposite end should be enough of a balance, I think.

SMDs? Sure, but I just havent mustered the guts to make the transition yet

And of course, IR would be the easiest way to go, but there would be issues with it interfering with the index pulses. Also, if I dont use IR, I could also get rid of the 3 pin module I am currently using. Plus, I find the concept of being able to achieve this thru' the existing hardware (nothing extra specifically for that) too tempting!
