This article gives constructional details of a very simple circuit which can be used to make the windscreen wipers of a vehicle execute complete double sweeps with selected delays between sweeps. Although it is suitable only for 12 volt cars having self-parking wipers which are driven by a motor with field coils, it is a very simple circuit which requires no relay or other moving parts. The author's prototype unit is installed in a Morris Minor 1000, which has a 12 volt electrical system with positive earth.
