Jonnydavro SEC – low voltage
A replication of Jonnydavro’s recent SEC circuit, here running from a 1.2V NiMH rechargeable battery. The circuit was able to fit on a small piece of experimenters board. An output pin (blue wire connected to it in video) enables trialing different L3 coils by plug n play. The picture at the end, shows all LED’s partially illuminating from the Ground connection, with no battery power.
