This series started in the 1960's Practical Wireless magazine and continued for many years.
That idea was that the circuit used no more than 20 components or cost more than 20/- (an old pound (Ł)). These are various transistor projects which featured in the series.
With thanks to Steve Payne who sent me these circuits.
