Occasionally some PC power supplies I’ve seen a different fan control circuit usually transistor circuits are used , but in this circuit 7805-5 volt positive regulator IC 1 7v zener 1 x 470 ohm resistor and 3k NTC used logic simple first voltage amplification phenomenon Let me tell you though 78xx , 79xx series and…
The LEDs according to the imagination of the person with a lot of things can get good work süslenebiliyor in this copper wires (coated) with LEDs, beads, using solar power light led bonzayi tree. The leaves of the tree consists of beads of green boncoklardan 1 ultra bright green led hiding between the simple circuit…
Fan speed control circuit 4 bc639 transistors are used on the circuit speed can be adjusted with potentiometer 47k. Intel CPU fan circuit used in the circuit tests based on phenolic hole about a new simple circuit for the low cost .. Source: http://www.soloelectronica.net/fan_espeed_control.html
RGB LEDs long ago lighting, including advertising signs animations etc. .. a lot like the application is being used colors can be checked wide range of application, but naturally single-color LEDs according to prices higher .. Honda Fit model, the RGB LED fault applications in the car, a different air 🙂 has added SMD RGB…
In this article made with LM3915 integrated LED vu meter is shown in Figure 10 . VU meter circuit feature , listened to music according to the severity of the LEDs are lit . So vu meter circuit indicates the level of severity of music . Music of the bass, treble and volume regardless of…
Electronics beginners, those who are keen know usually the first spark Audio (amplifier circuits, etc.) or light (LED effects, etc.) applications people cezbe would personally my başlangıg a friend of mine his amp circuit vision began with 🙂 A plurality of LEDs simple transistor circuit 555, and realized by integrated logic gate. Two-color LED lighting…
Nowadays, LED effects, animations LEDs, LEDs, etc. walking. In applications such as microchip, atmel, etc.. widely used in microcontrollers CMOS, TTL integrated circuits made with a lot of work still gürüy cost, low error rate and so on. more convenient to use for the particular application NE555 timer integrated circuit oscillator section is driven by…
Potentially hazardous voltage spikes on the power supply in a simple circuit can protect your device. Zener 12v low voltage determines the value that can be assigned. 10k potentiometer can set higher values than the 12v. To reset thyristor tic106 the circuit must disconnect the supply voltage. Protection Circuit Schematic Diagram
Led effect circuits, including myself, a lot of people might be interested, especially this sort LEDs and LED circuits have great interest in blue, white, LED prices now old and not so expensive LED effect circuit 12 LEDs used effects transition and speed adjustment buttons is done with used microcontroller ATtiny2313 Circuit source. Bass. Hex,.…
KA2281 previously with various vu meter circuit I made , but all mono circuit stereo manufacturer has two channels has been a challenge but in the end a bit of trouble in the scheme worked beautifully 🙂 Original diagram 15, 16 pins between the 50k resistor connected in this way the circuit full does not…
