Here, S1 and S2 are normally open , push to close, press button switches. The diodes can be red or green and are there only to indicate direction. You may need to alter the TIP31 transistors depending on the motor being used. Remember, running under load draws more current. This [...]

This power supply is not designed to use the prefabricated IC voltage regulators, even though such regulators do exist. The 7812 and 7912 ICs are quite capable of providing regulated +12 volt and -12 volt outputs, respectively. However, we have two problems with doing it this way. First, each regulator provides an output voltage accurate [...]

Circuit Supply Splitter with IC 741& TIP41,TIP42
If you must modify a place power supply. usual to dual power supply positive,negative,GND(0V). I introduces to try use. Circuit Supply Splitter with IC 741& TIP41,TIP42. When see the detail in the circuit make output of the circuit is pin GND(0V) the part [...]
