      Car Converter, 12v to 9v


      Parts List:
      R1 = 560 ohm
      C1 = 1000uF/16V, Electrolytic
      C2 = 100uF/16V, Electrolytic
      C3 = 330nF, Ceramic
      Z1 = 9.1V, 0.4watt zener
      Q1 = ECG184, NTE184

      Notes:
      To get a more precise output voltage, replace zener diode Z1 with 10V and R1 with a 1Kilo ohm potentiometer. A Coolrib for Q1 is optional. Simple circuit to power your 9volt cassette recorder and other stuff.
