Thanks for the offer! I haven’t made my mind yet. Funnily enough, just few months ago I bought some soldering equipment from the very same pajenicko.cz with the intent to improve my next to nonexistent skills, having this set in mind as a training field. IIRC, it’s recommended for kids around 12 years old. Can’t be that hard, can it? Maybe I’ll give it a try during the Christmas vacation.

Through-hole is not difficult at all. The main thing is to remember that the component leads (wires) must be hot enough to melt the solder. A common mistake at the beginning is to melt the solder on the tip of the soldering iron and then drip it onto the joint. This doesn't work and is called a cold solder joint. When done that way, the solder doesn't bind to the metal. If the leads from the component are hot enough to melt the solder you get a good physical and electrical connection.

There is a balance there though, since you have to get the wire hot enough that solder will flow, yet not burn up the component. So good solder and tools help a lot.
