Variable Time base oscillator circuit by cmos IC
Mini Projects
This circuit is a variable time base oscillator circuit that has operation as characteristics of high frequency pulse oscillator generator out to a Decade counter circuit. So that send a pulse signal appears at the output of one signal per the counting clock signal that as 10 pulse. Cause easy to building the lower signal to operation. Therefore, if require the output send the output signal with a 1 Hz frequency. We will must adjustable the frequencies generator to build the high frequencies up to 10 times of the output frequency that is 0.1Hz. Start with the frequency generator which …
Ham radio transceiver RF indicator circuit
Mini Projects
This is a ham radio transceiver Ham radio transceiver RF indicator circuit that small and easy to build. The application a Ham radio transceiver has 3 characteristic differential are Firstly is Monitored status or Sometimes called standby, Means to turn on the Ham radio transceiver to To listen or wait for a call from either one, will has signal in Input signal or not. Secondly is status that signal came in turn on may called Receive signal (Rx) Thirdly is a transmit signal status called Transmit (Tx) In circuit Figure 1 operation as standby status display indicator circuit or send …
Sawtooth wave generator circuit using UJT
Mini Projects
This is Sawtooth wave generator circuit using UJT transistors is easy. In the Figure 1 circuit used Q1 is UJT to connects with VR1(potentiometer), VR2 and C1. They acts as a sawtooth wave generator circuit, by C1 to charge and discharge. Then, current from the 5V power supply through VR1 and R2. This current and voltage that increase and reduce, cause Q1 generate signal. Which have the sawtooth wave signal or the ramp signal to output, which frequency is determined with R, C as above. Figure 1 Sawtooth wave generator circuit using UJT When Q2-transistor is is derived the signal …
CAR DC to DC converter circuit, output +/- 27V to +/-50V using LM3524
Mini Projects
This is car dc to dc converter project for converts from 12V car battery to dual voltage of +40V Ground and -40V (Available of +/-27V ; +/-30V ; +/-30V; +/-50V as setting parts) are used as power supply of 50W-100W amplifiers. When you want to increase your car amplifier. Essentially, there are 3 ways in the design of power amplifiers that operate with a 12V car battery. Firstly, The easiest way. It is by working directly from 12V. This ways maximum output power was limited to swing voltage at output. If it is assumed that the voltage drop across output …
