I must be nuts.

I am working on a calculator project that uses nixie tubes for a display.

I want to use a telephone magneto to charge up a cap to run the thing.

Kinda a steam punk RPN HP type of calculator.

I am stuck on what to use for buttons. I am thinking elevator buttons.

Large oak case. Just crank it for 10 seconds and then do your calculation.

I am also conflicted as to how many buttons.

Square and square root for sure.

Undecided about log, trig functions and whether or not to have scientific notation. I think I will.

How many digits to display? Probably 5. Engineering mode only. 3 dot 2 display.

Also considering multiple lines to show 4 levels of the stack but I doubt I will actually do that.

The question is: will I ever finish this thing?
