... Anyway, some of you are going to think so.
I'm soon to fill my first order for the new 1.25" 'dynamic' Sub-driver kit. A shot of the supplied elements of that SD pictured below
A relatively new development (eighteen-months old ... new to me!) was Mike's identification of a source for those microbe sized servos used in the little ultra-light aircraft that have been on the scene for a couple of years. By employing these very small servos I free up a lot of space within the cast resin servo box, at the center of the SD. by cramming some of the devices within the servo box, along with the servos you'll be able to shorten the SD length as compared to the SD employing the micro sized servos -- this permits installation of the SD within the smaller little plastic model kits. As initially conceived, the servo box would only accommodate the much bulkier micro sized servos, as seen below.
Problem is that the microbe sized servos have projecting mounting pads, elements of the PC board that comprises the foundation for all mechanical and electronic items. Pads, that prevent side-by-side use of the servo within the servo box -- the pads get in the way. Trouble is, that at one end of the PC board that set of pads has routed around their perimeter, conducting foil, both sides of the board. Cut off those pads and you clobber four circuit runs! Trouble is, you gotta get rid of the pads, and that means you're in for some SMT caliber soldering as you lay down some small gauge conductor to restore the circuit paths interrupted when you chop off the pads.
You potential customers up to it?
Here's what you have to do:
Being a 'dynamic' type system, this SD does not have a ballast tank -- you'll have to trim your little Revell/Monogram/Aurora/Ace/Lindberg/whatever plastic model submarine kit so that it floats with only the top of the sail sticking out of the drink. I'm sending the first ten of these out to Caswell Inc. this week. I then (after I get out of a lot of stuff I owe Mamas, Bill, Jim, and others) finalize the design, complete production tooling, and sell Caswell the 'static' version of the 1.25" Sub-driver.
Screw it, I'm going to bed!
