Wow, thanks all!
Sounds like the 1 crucial thing I was missing: FLUX.
Just scored a tub at my local BK hardware.
Jig: I just grabbed 2x heavy small slate tiles I've stashed, setting
that up as a fast holding jig. So simple, obvious now.
I've got a trusty hot iron, and I just dug out some more blunt tips I
accidentally ordered years ago! Luck, I think that will help.
Now to it, heads down...
Come winter, I was thinking of making more of this project, maybe as a
kickstarter- (I know there are at least 10 places in the world wanting
what I'm making ha). I may shout back asking about where in China to
get components assembled!
Yet, from this experience: if I was starting from scratch- I would never
have chosen to use these LED strips. I'm making a very large 7-segment
display, with individually controllable segments, and 10 characters
total. RGB strips are simple and cheap, but now I'm sure it would have
been faster/simpler/cleaner to use bare RGB LED's and learn Eagle or
something to produce a PCB to hold them- SO MUCH EASIER, probably
similar cost in the end.
Lesson learned- the sanest path to hacking up a project idea is not
always apparent at the start :)
Thanks again all! Now I really want to come to a Hack Manhattan open
night sometime just to bring a box of doughnuts for all you helpful folks :)
