Buying the bits
The biggest, nastiest expense are the magnetic shaft encoder chips which, thanks to the fact that they're made in Europe, are up to $12-14/chip. I'm told that Austria Microsystems has a cut down shaft encoder chip that I can get for under $3, but I'll believe that when I have some in my hand. I'm going to press them on that next week.
The Euroboard stripboards have gone up in price as well, something like 50% to $15 since the last one I bought in April. I'm thinking that that is more Potters' than a real bit of inflation, though.
My son returns on the 15th and asked if I'd have a prototype running by then. I'm going to see if I can manage that. My client's web services server went south last night so I can't do consulting work till Monday, so I'm going to have a good run at it between now and then. :-D
I may opt to use your plans over those of a "true" reprap.
Or, I may improvise something else, when the time comes.
