I will never forget. At 7 I've got and old russian book (a very good one)
with 100 schematics of radioreceivers using only one and two transistors.
I had one russian transistor called PI13. I've reproduced all
schematics using that transistor on a manufactured breadboard (one
which first need to be drilled, then
mount the copper staple in the hole, then riveting, etc)
None of them works for the simplest reason the transistor was short
circuited between colector and base.

It was extremely usefull for next yers when I knew exactly how to
manufacture a coil or how to read colour code for transistors and
resistors.
Just soldering and sorting components like playing it's a good choice.
Lighting a LED from an 1.5V battery. All will be usefull later.
