-Sealed!

Somewhere between $70 - 100 would be great. Cheaper it is, the more we'd buy most likely.

Currently I think, as was touched on above, that a FIRST speed control should approximate the design of the Victor in the sense that the body of the speed control should fit under the fan with perhaps the exception of I/O and power connctions which, like the Victor, sit beyond that perimeter.

I was thinking that the power board would be situated directly below the fan along with, at minimum, that board's power connection (high current so less connectors and trace length the better) sitting beyond the fan's perimeter when looking straight down at that fan.

I was thinking to put the control or 'interface' module directly below that power module.

If you were using the 'custom circuit interface' I was thinking that your custom circuit would be the lowest level of the stack.

For prototyping one could use ribbon cables to essentially unstack the modules horizontally.

The fan would blow directly on the parts most likely to generate heat.

If necessary a much smaller secondary fan could be put on the side of the stack to move air between all the modules.

I was also thinking that a piece of cold laminated aluminum foil or copper foil could be stuck between each module as an RF barrier if one desired. That item being light, somewhat rigid and most importantly with a surface that's not conductive. It's like the foil in an Apple computer it could be sort of folded to something like a shield. This would also help with swarf besides sealing all the boards and possibly putting it all in a suitable box.

I realize that the the cheaper the unit is, the more would be bought, but Dsirovica is correct above that a community project in the early stages will be cash strapped without benevelent benefactors of faith. I can throw around a few thousand dollars out my pocket. However our initial bottom line ability to ram down the price will depend on whether the near production prototypes make FIRST drool during the approval and whether someone else comes along and opens their pockets as well. I hope that as things advance and we crystalize on basic business functions and tangible work; we acquire not just community hands but some community contributors. I can respect deeply that as of this moment the economy is a very tough place for seed money which is why I pulled out my wallet and my production resources and offered to help. I have faith in you all to deliver...if not this year...then perhaps next.
