- .. store and safely handle. Once the BOOSTCAP attains 1.2 volts, it has enough power to allow the MintyBoost to provide a 5 volt source for the device being charged. On the input wires we attached a 5A diode so that we don't get an ...May 25, 2009
- .. do. However input voltage of near ground level is little difficult to use due to following reasons. * Voltage not drop to 0 volt. Capacitor voltage will not be discharged to zero volt. It require a time to discharge capacitor to sufficientaly ...May 25, 2009
- .. you put a faster oscillator in the pic. It works on my test device, but running the pic at over ~8MHz with only a 3.3 volt supply can be problematic. So I hear. I’m still working on the WAV stuff, so if you have some funny results ...May 18, 2009
- .. my impact on the planet. Also, because this controller is so simple, it only needs one power suply, so, it only needs 1 12 Volt (for both the logic and the motors), instead of 1 5 Volt (for the logic) and 1 12 Volt (for the motors). This ...May 7, 2009
- .. If you apply a specific voltage to a resistor, you can compute the resulting current with: I = R/V Example: I = 100 Ohm / 5 Volt = 20 mA Obviously that does not work with LEDs because they don't behave like a linear resistor. If you look at ...Apr 6, 2009
- .. FET, which can turn on a beeper or activate a relay. If a low power voltage comparator is used, such as the LMC7211 , a 9 volt battery will power the circuit for many years. The more popular LM358 would also work but would draw more ...Mar 31, 2009
- .. the iPod. Apple's claimed battery life on this iPod is 10 hours. That's two hours less than the previous Shuffles. The 3.7 volt lithium-polymer battery lists a capacity of 0.27 watt-hours. To calculate the capacity in amp-hours, we know ...Mar 24, 2009

- .. This circuit will power a 6 inch 4 Watt fluorescent tube off a 12 Volt supply, consuming 300 mA. It may also be powered by a suitably rated universal AC/DC adapter. Advantages of the ...Nov 5, 2008
- .. close values are OK although the values shown are quite common. The 1 uF capacitor may be just about any type, with a 16 volt aluminum electrolytic being the most likely choice. The capacitor will see about 1/2 volt reverse bias at times ...Nov 5, 2008
