I can't disagree with the idea of sending money to a fictional address being unsettling at the least.
I believe you are mistaken about her equipment though. That gun is slightly more advanced than one that is used for solar panels(I've placed a few). She appears to be holding a pick in her left hand and I would assume that solder gun has the 'bulb' built in, i.e., bead type. Not real up on those but I know its a lot more advanced than your standard, tamp controlled gun. Note the Cute Tape ships there behind her working platform. And, look closely at the edge of the white binder there. It bears the name of some equipment that is not cheap and jsut wouldn't be thought of to fit 'the scam', imho. hell, that Dry keeper alone is about a grand.. $300+ magnifying light.
The shadows from the boards look right to me and the luminescence and sharpness of the photo seems to match enough to be from the same or similar quality camera as their others. Though, I suppose it is possible they hijacked a picture of a lady working at a desk at a lab and imposed the boards into it...
Lots of people have equipment and I tried to look up the manual but could only make out "Machine Manual - MY Series Vxxxxxx Series 2.4". Just because you have the manual to something doesnt mean you have the actual item. It could be another part of an elaborate ploy to make them seem legit or maybe she really does work with electronics.
The shadows do not add up no matter how you look at them on what some people called the heatsink covers (unmarked silver casings). They do for the one in the bottom left but not for what she is working on. The one on the bottom left you can see the reflection of the capactiors but this is also possible to do in photoshop. Even if the boards are real other people have stated that they could have ordered some that are mocked up for them for cheap. The shadows on the ones she is working on and the fact she is soldering on a side that doesnt have solder connections is indeed strange.
It is possible to build a bulb into a soldering gun and I assure you I do not use a standard solar panel one as I test and certify them. I build custom electronics to test and verify them however and it does seem a little large. As I said I hear all kinds of claims and always view them with a degree of skepticism. I have been proven in the past and it would be interesting if I was.
Even so they could have raised a lot of capital to further this scam at $500/pop already though.
Once again, just playing devil's advocate here, but you don't think that she could have just held up a tool and a board to pose for the picture that she's obviously posing for?
