I am having problems trying to solder, right now I can't solder right a circuit board such as the one that I showed on another post, the real size of the board is about 1.25 Inches by 2.25 Inches, very small about the size of a 9 volts battery, but thin of course.
The copper holes' pads and the copper traces are small and all the traces are too small and close together for me, I have not done any soldering for very many years and now not only I am out of practice soldering, but my eyes' sight is even a lot worse than it was some years ago.
I will try to retrain myself to see if by practice I can learn how to solder even with bad sight, I used a magnifying glass, but it was not enough, perhaps with more practice I can solder better, otherwise I won't be able to build some electronic circuits, there are other possible ways of building some circuits, but not all of them, perhaps I should start to practice with 1 transistor circuits and then if I can do those then move on to 2 transistors circuits and then to harder to build circuits.
Bigger PCBs with holes' pads and traces that are farther apart from each other should be easier for me to solder, well for the moment I won't try to build that circuit, I will only practice soldering for a while then I will either try to build that circuit or try to build some other one.
So no more of these posts until then.
