Mini function generator circuit using ICL8038
Mini Projects
This is the Mini function generator circuit using ICL8038 IC-number. (Precision Waveform Generator/ Voltage Controlled Oscillator) It will generate output 3 the waveform, include Sine wave signal,the triangle, and square wave signals. The output of this circuit is quite realistic in the waveform. And we will suggest a 2 model include (1.) the basic model (2.) the improved performance model,we can customize even more. If you interested, don’t wait. Let’s see it below! The Basic circuit diagram function generator using ICL8038 Figure 1 The basic circuit of function generator using ICL8038 The Basic characteristics of the circuit with a few …
Christmas Tree Lights Flasher with 7812+LM380
Basic Circuits
This is Circuit Christmas Tree Lights Flasher with 7812 for supply regulator and IC LM380 for Signal generator dirve relay on-off the lamp two set. detail other see circuit. The Christmas Tree Lights Flasher Circuit. It is Lamp flasher that interesting by use IC LM380 for Oscillator generator model Pulse Osc. Low Frequency for use relay switch give Lamp 220V. A lot of get for the accuracy of the circuit then must use IC 7812 DC voltage REG 12V And R1 use fine winking speed of all light bulb. The detail is other see in the circuit better sir. Table …
Many Constant current source circuits
Power supply
      Sometimes we need a constant supply to the load.To prevent damage to the load.For example, when we apply a voltage that ever-changing to LEDs. However,LED needs to have the constant current and voltage. As usual, we provide current limiting resistor to it. But this works we can not use because the input voltage changes all time. We must make a constant current through the LED. If you do not understand. Try to preview the circuit below. The Safe constant current source.       Figure 1 the below is a Safe constant-current source circuit, how it works?       A cmos op-amp (number ICL 7611) …
Mini audio amplifier circuit
Basic Circuits
This be mini size power amplifier 2 watt OTL that use IC LM380. Be base readymade circuit for side sound work and the communication. Which use outside equipment adds least. The C6 can choose get many the value since 47uF to at 470uF which , have a voice good bass. The C3 use for decrease tall frequency or noise. It be valuable stay between 0.0047uF sections arrive at 0.047uF. And use to The 12V power supply (8V to 12V) from , car battery or the other.The Pin 3,4,5,10,11 legs and 12 soldered directly with copper side of PCB. Which use …
