Power supply positive-negative-ground from a single power supply

Sunday, October 17th, 2010

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 [...]

dc to dc converter using ic ne555

This circuit is called DC TO DC converter circuit.Which increase the voltage circuit.There can be customized to change the output values. When the power supply input to IC1 is the output pin 3 at a frequency of 1 kHz.The frequency is Q1 and Q2, which will continue to use push pool work interchangeably.If this is [...]
