 DIY Cheap Resistance Decade Circuit

Thursday, November 13th, 2014

Here is DIY resistance decade tool for testing and calibration, because it can be substituted into a circuit with a all standard value. This ideal is cheapest that use resistors and wires only. In each experiment, a resistor must be involved at all times, and Often unable to find the required resistance. This problem will […]

 Symmetrical Harmonic Oscillator circuit.

Monday, November 10th, 2014

This is the Symmetrical Harmonic Oscillator by the harmonic 3 that without tuning circuit because normal circuit use harmonic frequency always has the tuning frequency circuit. This is Astable multivibrator Oscillator circuit that has the crystal across between both emitter lead of transistors(BF494). The 40pF trimmer capacitor-C5 is connected with crystal to adjust the fundamental […]

 27MHz CB Amplifier Circuit

Sunday, November 9th, 2014

The V-MOS FET number VN66AF (as Figure 1)is produce of the Siliconix company, for outstanding features are as durable and high gain. Most application of this is a normal power amplifier circuit. It can be used as the RF amplifier circuit. Figure 1 the V-MOSFET no-VN66AF This circuit (as Figure 2) is the RF frequency […]

 Simple 555 ICs tester circuit

Monday, November 3rd, 2014

Most IC-555 is used to generate frequency, and sometimes we need to know. Is it good or bad? But normal multimeter cannot check it. Thus, I make a simple 555 ICs tester circuit. Which is tested correctly and faster. How it works Resistors R1-R3 acts as limit current and reduce voltage to LED1-LED3. Which is […]

 Electronic Head or Tails Circuit

Saturday, November 1st, 2014

This is an electronic head or tails circuit ,that same really the head or tail playing very little head by following several steps. -First of all,turn on switch, LED display show digit “0”. -Secondly, press the button “rotate” then the coins computer will begin rotate, notice of LED1 will be light, wait until LED1 go […]
