There are too many circuits described much too short. A master plan for gradual learning is completely missing. Previous experience is definitely necessary if you want to understand anything at all.
The circuits ranging from simple series connections up to the differential amplifier, or a kind of radio. Everything each explained in a paragraph of text.
Then build the circuits there once the circuit diagram and a photograph of the finished structure. You need both, because on the black and white photo is much difficult to recognize and who looks only at the plan must think twice as he ansnutzt the narrow space on the board for the circuit properly. Impractical that both is often on different sides and man has to scroll back and forth.
Many switch within the circuit wire ends must be used. Here you have to watch that do not touch the closely spaced components.
After building some circuits do not function properly. The transducers have never given me a sound and the RS flip-flop transistors lock not exhaustive. I suspect that the components are not matched possibly properly matched. The texts also contain various !! Spelling / grammatical errors.
The accompanying CD-ROM is meant this nice, acting in their appearance but antiquated. Simple HTML pages with links to some static simulators. Works like a hobby website.
Anyone who wants a little bit playing with electronic components can do that here, but if you want to get into the electronics for this is certainly nothing. It can lay in wanting more awaken but for someone with basic knowledge who wants to deepen this is not appropriate here. Moreover, the price is just too high. Comparable in size electronics dealers costs only one-third.
Clearly no recommendation from me.
