OK, so the mysterious dingus isn't exactly a nuke (though it is, technically speaking, made of atoms). But it does have that connection with missile guidance systems.
Anyway, Prototype #1 is now ensconced in its entirely peaceful application setting, and Joy was playing with it a while ago. Seems like my choice of coefficients was just about right, so no need to fiddle further with the firmware at this stage.
Revised board - mainly mechanical improvements - is in the hands of OSH Park, awaiting a 4-layer panel. It's a tad bigger, costing a whopping $11 per three pieces. I've ordered a half-dozen, and this time I guess a solder stencil will be appropriate (on account of I'll be making multiple units, and also having consistent amounts of paste seems like a good idea, so there maybe won't be the annoying cleanup phase after reflow).
There'll be a private showing of the product on, I guess, Sunday, then a semi-public one on Wednesday. After that, maybe I'll reveal the nature of the gizmo.
