- .. regulator 78L05 , some NPN transistors and a pair of logic MOSFET IRF510 as a final amplifier. Click to enlarge 1000 Volt DC to DC Regulator Circuit The workings of high voltage DC to DC converter is the same principle as written in ...Dec 15, 2010
- .. off and there is absolutely no current drain from the battery. When the sun gets up and panel starts producing at least 10 Volt, the LED lights and the two smalltransistors switch on. This powers the regulator circuit. As long as the battery ...Dec 5, 2010
- .. output in just a couple of times the ground so a voltage divider (1K/470) is used to reduce the voltage signal at about 0,7 volt. An additional diode added in series with transistor base to ensure that off when the voltage op-amp is 2 volts. ...Dec 5, 2010
- .. a Savonius rotor. At 200 RPM the output is only about four or five volts. While this is obviously not enough to charge a 12 volt battery by itself, a bit of clever circuitry solved the problem. Some time back a circuit was published in one of ...Nov 1, 2010
- Forrest Cook.. device that can control DC devices which draw up to a few amps of current. The circuit may be used in either 12 or 24 Volt systems with only a few minor wiring changes. This device has been used to control the brightness of an ...Oct 15, 2010
- T.K. Hareendran.. hobby circuit of an automatic garden light using a LDR and 6V/5W solar panel. During day time, the internal rechargeable 6 Volt SLA battery receives charging current from the connected solar panel through polarity protection diode D9 and ...Oct 12, 2010
- .. is used as power control. For hum-free operation, operate the transmitter on a 12V rechargeable battery pack of 10 x 1.2-volt Ni-Cd cells. Transistor T2 must be mounted on a heat sink. Do not switch on the transmitter without a matching ...Oct 7, 2010
- Andy Collinson Description This is a replacement power source for 1.3V mercury cells or other small batteries. It has many uses and I use this circuit in my computer to power a front panel multi adapter which has a digital thermometer. Notes This ...Oct 4, 2010
- .. T1 is a transformer that monitors the electric supply. It is rectified by a bridge rectifier and smoothed by C2 giving a 15 Volt DC supply. The 15V supply is the input to the LM317 regulator. The regulator output is set by R1 and R7 to about ...Sep 27, 2010
- .. in the inductor. The circuit is built around a quad low noise FET input op-amp, type TL084. Power supply is a single 9 Volt battery, the supply being divided by R5 and R6. C1 and C2 help smooth variations in battery voltage, S1 is the on ...Sep 7, 2010
