Re: U3s was working with one BS170

I would echo the compliment about Optivisor magnifiers.?? I got
mine, a 2.5X from my father-in-law.? Later I picked up a 2nd one that was a
bit stronger¡ªabout 3.5X? I think.? The nice thing about Optivisor vs.
many of the other cheaper versions you see, is that the Optivisor lenses don¡¯t
degrade as you look towards the edges of the lens.?
?
More recently I¡¯ve found another method that works pretty well¡ªusing strong
reading glasses.? I use readers anyway, so I¡¯m comfortable using them, even
if they have a stronger diopter rating.? Sometime back I ran across a type
of reading glasses that I really found to be handy.? They are called
¡°Clics¡±, and they have a lightweight collar that goes around you neck, and the
two lenses separate in the middle as they are held together by a magnet!?
So, when not in use, you just pop the lenses apart, and let the glasses hang
around your neck.? When you want to use them, you just ¡°click¡± the two
parts together magnetically.? They are really very handy.? The Clic
brand is? bit expensive, but I found some knock offs that are almost
identical and far cheaper (on Amazon).? So, I picked up a stronger
pair¡ªabout 3.5X, and use that pair quite often for soldering work.?
?
If I need something much stronger than 3.5X, like to give close inspection
to a solder joint or SMD connection, I just use one of the loupes I picked up at
Harbor Freight¡ªthey were cheap, but work pretty well.

I've
posted before about the header socket pins being difficult to solder (and not
worry about it melting). That's not to say you're having this trouble as well,
but it wouldn't hurt to go over the boards with a good magnifying glass and look
for cold solder joints. I'm a big fan of the Optivisor line of headband
magnifiers; I have one my dad used from the 70's and picked up a couple more at
a garage sale. The 5x I use for normal work and 10x is good for checking fine
detail. But, my close-up vision isn't what it used to be. Remember to breathe
and again, good luck!
