- .. or a super-regenerative detector feeding a dynamic earpiece through an impedance transformer. The power supply is a 9 Volt battery and the telescopic antenna contains a base loading coil. The switching did intimidate me a bit. While not ...26-03-2008
- .. to the other transistor base and reverse the meter leads. If the voltage on the 2.2k resistors isn't low, maybe under a volt, try cleaning everything with a solvent and thoroughly drying it. Once the reading is low and steady, hold a ...23-04-2008
- .. resistance needs to be high enough to not exceed the power supply current limit. I wanted to stay below 0.5 amp with a 5 volt supply (5 / 0.5 = 10 ohms) and targeted 10 to 15 ohm coil. Figure 2. Electromagnetic coil. As the circuit has now ...21-10-2016
- .. 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 ...05-11-2008

- .. 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 ...07-09-2010
- .. 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 ...24-03-2009
- .. 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 ...18-05-2009
- .. 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 ...25-05-2009
