If you are looking for AC power measurement. To use it just a little, which is not worth it. When we need to buy an expensive tool. Because use little does not need high accuracy. I would like to propose the concept of wattmeter circuit in such a way easy as it was.I collected all … Read more
This is long range fm transmitter circuit in VHF range. As Figure 1 Sonar with up to 2 watts, when used with a supply voltage of about 24V. Read more
This is FM transmitter circuit without Coil, using inverter digital IC as main and controlled frequency is precise by a crystal. In Figure 1 is RF oscillator circuit which use an inverter IC1/2 and ceramic crystal filter 10.7 MHz to use drive IC1/4 – IC1/6 by through IC1/3. Figure 1 the circuit diagram When inverter … Read more
These are four 1.5V FM transmitter circuit (low volt) which use transistor and a few parts, without PCB but easy to build for output 88-108MHz or 90-100MHz, more circuits below […] Read more
