Re: Here We Go - My First Newbie Question
- I used the method on Cash Olsen's web site using the hot air gun,
solder paste and a coffee cup warmer. I got the heat gun locally on
sale at Hobby Lobby for $12 and the cup warmer at Walgreen's for
$3.00. I ordered the solder paste from Cash on his web site, so far
we've used it to build 2 boards and haven't even made a dent in it.
I'm no spring chicken either (47 next month) but a pair of cheapo
reading glasses (also from Walgreen's) and a gooseneck light clamped
to the edge of the desk was all I needed. I borrowed a lid of a cake
pan to keep the parts from rolling off the desk, it's now back in the
kitchen and my wife didn't even miss it.
Don't worry about the smt parts, I was sweating it but it was actually
the easiest part of the project. I was wishing more of the board was
SMT. The other parts took much longer than the SMT parts.
