Haven't posted in a while, so here's a bit of catch up for the electronics side of some of what I do...
I picked up 2 Fluke 8050As for $10 each. They're about 36 years old (or the model is), but they work. I only have 1 set up. The second is a spare as they are over 30 years old.
And my $9 soldering iron was worth, um... I had to get a new one. I couldn't find a used one, so I ended up getting a Weller WLC100.
It's the bottom end, but it's a hell of a lot better than what I was using. So far I'm very happy with it.
And I kept running into situations where I needed to know more than my Fluke was telling me. I searched and searched and searched and could not find a used oscilloscope anywhere for a decent price. Ordering from the US was out of the question as I'm not paying $200 shipping for a cheap, old, used scope.
After searching for about 3 months and turning up nothing, I finally broke down and got a low-end oscilloscope the other day.
The reviews for it are all very good, and I'm sure I'll be happy with it if better people than me are.
