  2. .. to measure the power consumption of a device. In this project we are building one (Figure 1). Figure 1. DIY Digital AC Watt Meter. This is an AC Watt Meter which can measure the real power consumption of a device connected to the ...
  3. .. a simple and cheap circuit that features easy adjustment and good accuracy. The output signal can go directly to a panel meter or a microcontroller, requiring no complex data manipulation such as log or antilog calculations. The MG-811 ...
  4. .. and output was also required, so I could not use an integrator or other simple design. The circuit is used in a distance meter, which is why little and constant delay between input and output pulses is so important. Testing has ...
  5. .. trigger inputs is used to build RC relaxation oscillators for both digitizing analog sensors and for producing the radio frequency (RF) signal required to transmit the sensor values wirelessly. A reference design for a wireless ...
  6. .. not provide much current to charge the gate capacitance quickly, these photovoltaic couplers are mainly used to drive low frequency MOSFET switches, such as solid state relays. Here (Figure 1), an attempt has been made to use a ...

  8. .. again, the oscillation starts from whatever state this was. Another unusual feature of this circuit is that it can act as a frequency divider. If the control input is a repetitive signal, and R1 and C1 are chosen such that the oscillator ...
  9. .. a gain of one this circuit has an SNR of 77 dB and a THD of 84 dB, with a sampling rate of 4.5 Msps and a 600 kHz input frequency. These numbers are close to the typical data sheet performance specifications for the LTC2314-14 alone, ...
