Yup, I'll be crunching some numbers based on that soon, budgeting in a low-cost MCU, connectors, and mux switches, and LEDs. We are going all solid state on this one. I'll also through in what I hope it will cost for the PCBs from the manufacturing plant. Assembly will all be done by hand, I am quite comfortable soldering.last edit: cost analysis projections need to be done FIRST in product development. Design specs are based upon those projections.
I have some more things to say in reply to what you have said, but, not being at my workstation, it is difficult to reply.
