Anyone know of places to buy this kind of thing in NYC? I'm sick of shipping stuff from China ;p
I love the optical sensor idea... have an opaque tab pass by it once per mirror rotation, yeah? Maybe I can source one from a discarded object. I believe old mouse wheels use this... what else?
newark.com? How far of a drive is it to Jersey from where you are?
Speaking of New Jersey, I once had to go back there to attend a company hardware training class in the 70s for several weeks. We took a trip one weekend day to check out the Edmund Scientific store. I had seen their mail order catalog for years, but actually going to their store was a real treat. They had everything out for display that they carried in their catalog which quite surprised me. They also had a real cool functional war surplus submarine periscope setup in the entry lobby that was very impressive to look through. Cool memories.
