Switching Regulator for High Power Efficiency When you should regulate a high voltage to a much lower voltage, switching regulator must be the only choice. Fortunately, a simple switcher integrated circuit chip is available, let you build a complete step-down switching regulator using five components. The switching regulator IC used in …
Read MoreWhat is A pH Meter? A pH meter is actually a precise voltmeter that measures the generated voltage of a pH electrodes. The requirement of such meter is high input impedance and has the gain of voltage-pH conversion. The standard pH probe generate voltage about 59 mV per pH, so all we …
Read MoreThis AM/FM antenna booster circuit amplify the broadband signal from antenna. This antenna booster should work fro FM, AM, and SW receivers. Here is the schematic diagram of the circuit: Using this antenna booster circuit, for short wave reception, an 8″ antenna would produce a strong signal level equivalent to a 20 to …
Read MoreThis is example of a simple inverter that can be used to power fluorescent lamp and a small strobe. This circuit will produce over 400VDC from a 12 VDC, 2.5 A power supply or marine battery or an auto. This circuit is very simple because it does not require custom transformers or coils. Also all …
Read MoreTo extend the measurement range of an available ADC(analog to digital conveter) we can use this autoranging. If it implemented on multiplexed input, this circuit will give best result. To adjust an ADC’s full-scale range we use a system autoranging that use LTC1257 because it is appropriate for system autoranging. During …
Read MoreThis temperature controller employs an LM135/235/335 temperature sensor, can be used to keep small environment warm or hot. Here is the schematic diagram: LM311 is used as comparator, to detect if the voltage at sensor pin (the inverting input) goes higher than the reference pin (the non-inverting pin). If this condition is …
