A simple useful implementation of the low powered toroid oscillators shown recently. 3x 1.8W solar panels are connected to a rejuvenated car battery (was completely dead, sat outside for a couple of years and a homemade Bedini wheel knocked the sulfation off). The battery connects to a LM317T circuit, which converts the power to a constant 1.2V. The circuit is within the datasheet.for the LM317T. Out then, to a 1200 turn approx 1" ferrite toroid, with approx 70 turns as the Primary. A 2SC2655 then supplies the switching to power the mains rated LED night light. The light can be left on 24 hours a day. It uses only 5mA. The best running brightness can be regulated with a pot on the LM317T circuit (20K). The 3 homemade battery cells run 'Penny' oscillators, see Lidmotor's channel for the circuit diagram for that circuit. Note - Zinc Oxide not magnesium oxide is used within the seashell cell. All 3 were stovetop type cells, see IBpointless2's channel for a video where he shows how to cook down the ingredients
