Power supply positive-negative-ground from a single power supply
I like to try different circuits. Using adapters as a power source. Which it has disadvantages be it can not turn on the negative power supply.
However, this circuit can supply both positive and negative.
This circuit is used IC number NE555 set up to stable multi vibrator.It produces a frequency rectangular patch of about 100 Hz.Out to pin 3 through C3 and C4. Before the rectifier power section. Both positive and negative DC 2 series.Positive power supply will work with the rectifier D1 and D2.When a positive signal to be via D2 to the output.
