The concept discussed here remains exactly identical to the usual joule thief configuration, we just replace the normally used 5mm LED with a 1 watt LED. Of course this would mean the battery getting drained pretty much earlier than a 5mm LED, but it’s still economical than using a two 1.5 cells and not including a […]
Higher
Higher Variable Output Voltage from IC 7812
You may have often wondered whether it was feasible to get higher voltages than 12 V from a 7812 IC? In this short post I have explained how to configure the IC 7812 with a BJT stage, so that its output can be made variable for achieving any desired voltage higher than 12 V, without […]
