“An interesting selection of parts but poorly presented. Although there is a list of components on the front cover, this list only gives component numbers - very frustrating to have to research IC names, functions, and data sheets. The 8-ohm speaker that came with my kit had very poor solder connections. Luckily, I could still use the speaker by clipping leads directly to the speaker wires and bypassing the connection pins.I would not get this kit again”
