Science Fair 150 in 1 Electronic Project Kit. Very rare to find these days, and nothing produced today comes close to this amazing kit.
Features all sorts of electronic projects and components, easy to wire up.
Fantastic educational too as well as loads of fun. The very detailed manual explains what each circuit is doing as you build it. Ideal for learning about electronics for kid and adults alike.
I have been able to test most of the components and the ones I could do (with my limited multimeter) were working fine.
