Those of us expecting or desiring a guaranteed and on-time result should have gone to a hardware store and bought a magcharger ready-made. Those expecting a team of engineers to drop everything else they're doing and work around the clock to solve all problems once the schedule slips should consider how much money is spent on military and NASA projects to make that happen (and those projects slip anyway, often by years). Yes, if NASA wanted a light like this, United Technologies would have been happy to bid on the job, and you can imagine what the price tag would have been. The USL project was what in industry is called a "moon shot" from the very beginning. That means it pushed the technical envelope hard enough, and in enough ways, that it had a high probability of total failure (defined as never delivering any working lights), so it's already done far better than what might have been, and we should all feel some relief that it's gotten to where it is.
We all had a choice between making an exciting but risky investment or buying a Magcharger, and those of us who opted for risk and excitement should certainly have understood that we were not guaranteed a Magcharger outcome. And as for markup: I used to work at a place that did this type of stuff (custom hardware development), with much more conservative technology choices than the USL's, and we marked up every project by 800% (eight hundred percent) in order to be reasonably sure of not getting clobbered by the uncertainty in any advanced development effort, and even still we sometimes took a bath. Applying that standard to Nitnapz's $175 cost figure, the USL would cost about $1400 per light if done as a real business deal. As it is, we're participants in a recreational project, and seeing all this stuff happen and experiencing the ups and downs and taking them as they come is part of what we signed up for. (Also, IIRC the USL price was $265, so the $325 that Nitnapz paid must include a charger, spare bulbs, or whatever. And I think the $265 was intended among other things to cover a fair number of spare battery packs at Bill's end to replace failed ones of which there have been quite a few).
Of course I'd like to have gotten my light (#43) sooner but I continue to be satisfied with Bill's persistence and determination. I see he's still working at it, progress is happening, I even feel pretty confident of eventually getting a light, and seeing the story unfold through its twists and turns has itself been worth most of the admission price, so I'm not stressing out about it.
The thing that frustrates ME most is that this build has soured Bill to the point that any of the other creations he had thoughts of long ago will never be offered out here for sale.
I agree with everything in Bright Scouter's post and this last point is an especially perceptive one.
