- .. temperature and pressure sensors as well as to monitor the battery voltage. To maximize accuracy I used an external 4.096 volt 0.1% reference from National Semiconductor. With the 10-bit A/D, this provides a resolution of 4mV per count. The ...22-12-2009
- .. all charged up and running. My girlfriend complained about it not having enough power to run her blow-dryer though. Here my volt meter is showing the turbine producing 14.5 volts in a stiff wind. Although the wind turbine powered the popup ...25-12-2009
- .. at sea level, and about 2.77 to 2.45 volts at 10,000 feet. Most of this range is above the active voltage range of a 5 volt opamp circuit. In effect the sensor voltage is referenced to the power supply, not ground as desired. Fortunately ...10-01-2010

- .. N0UK, G4JEC I can't believe I never thought of this before! This simple modification is applicable to pretty much any 12 volt operated, positive earth equipment. It was described to me yesterday by Bruce, W9FZ, as a method that many ...24-03-2010
- .. Mohankumar Here is an Energy saving battery charger. It harvests solar energy to replenish 12 volt Inverter battery. It has auto cut off facility to stop charging when the battery attains full charge. The charger ...27-04-2010
- .. Fareed Description Except for use as a normal Battery Charger, this circuit is perfect to 'constant-charge' a 12-Volt Lead-Acid Battery, like the one in your flight box, and keep it in optimum charged condition. This circuit is not ...04-06-2010
- .. moment too much current is flowing biases Q1 and drops the output voltage. The output voltage is: 1.2 × (P1+R2+R3)/R3 volt. Current limiting kicks in when the current is about 0.6/R1 amp. For a 6-volt battery which requires ...04-06-2010
