kits and assemble them. Now get them to WORK.
Kits are great at teaching you to
solder, to identify compoennts and
to put things together. They are less good at teaching electronics.
Depends on the kit. The one kit I built included a schematic, a block
diagram, and a reasonably detailed theory-of-operation section.
Of course, that _was_ some 35 years ago.
It still does depend on the kit. I came acors san American company who
still seem to sell kits with exceellent manuals in the style of the old
Heathkits. I'll try t orememebr the name. Alas the kits are not gernally
available over here.
The common kits in the UK are Velleman. With those you genreally get a
shcmeaitc. The instructions, though, anre jsut 'fit these components in
this order'. Axial-leaded components are suppleid on the bandolier strips
in the orider you fit them, which rather takes the fun out of it :-) No
theroy of operation, genraslly.
Maplin also do a few of their own kits and those have terrible
instrucitons. Just a parts list and a PCB layout. No schrmatic, no
theory. With on of them I had to puzzle for a bit on how to put it
together, and I am hardly a newbie...
