Ampli Trafo rakitanku ini menggunakan Trafo IT/OT 420/426 dengan 4 buah Transistor NPN 2N3055 pada Penguat Akhirnya, catu daya tunggal 6 Ampere 12 volt, daya keluaran sekitar 60 – 100 watt. Bagian buffer awalnya dulu pakai Transistor C1061 dan D313. Q7 bluetooth mini headset manual Yamaha 5 1 amplifier rx-v596 manual Error.

How to make PCBs below my experience is the most practical, but the cost is very low, the result is no less attractive and neat compared to using the media Transfer Paper (original) the price quite expensive or printing etc that would be more complicated. Most of my friends probably already familiar with this method, but for others it never hurts to be used as an alternative. Its very simple! Watch the below video! Pdf tafsir al quran per kata maghfirah hussein. What you all need is a, copper clads, sand papers, a printer, computer & an iron! You are done! I will explain the entire process later in words! Video membuat using Printer-leser This video sows How to etch PCB using Ferric Chloride. You can do this in home in a simple way. Me too have done etching in home using Ferric Choride before & I am sure you will love this post. Video membuat using Ferric Chloride. This circuit is of a street light that switches ON when the night falls and turns off when the sun rises. In fact you can this circuit for implementing any type of automatic night light. This circuit can be used to lights or other electrical equipment with large power to hundreds of watts The circuit used an LDR to sense the light. When there is light the resistance of LDR will be low. So the voltage drop across POT R2 will be high. This keeps the transistor Q1 ON. The collector of Q1(BC107) is coupled to base of Q2(SL100). So Q2 will be OFF and so do the relay. The bulb will remain OFF. The assemble cables for DC power supply and output transistors must be large, use size 1.5-3mm for large current passed. The supply used transformer with 20A/45Ct and at least 4x10000uf/80 volt capasitor. This circuit is able to supply power 10000watt therefore the power transistor will be very hot, give good cooling fan on the power transisitor Transitor alternative to replacement of the 2SA1494 is 2SA1216 From SANKEN. The transistor has a 200-350 watt power dissipation of each pair so that for long-term operation of more durable. Keep in mind, usually sold a pair of power transistors with its complement, so you can not buy 2SC2922 alone without 2SA1216 or 2SA1494 without 2SC3858. The price range for transitor tsb is 30-40 thousand Rupiah / pair. Saklar sentuh Berbasis IC 555 This is the simple circuit of diagram of a small touch using IC NE 555. This circuit is ideally useful for making touch operated doorbells, buzzers, toys etc which when touched on the touch plate operates the relay for a preset time and the turns off automatically. The circuit is realized by utilizing the high input impedance of trigger pin of the IC 555. When the IC is triggered by the induced voltage of human body the output goes high for a time determined by R1 and C1. The transistor is used to drive the relay. The relay contacts can be used to drive the load like bell, motor, lights etc. To setup the circuit connect to power supply and adjust R1 while keeping touching on the touch plate. Stop at the point where relay activates.If relay is in the activated state initially then do the same until the relay is deactivated. Skema sentuh Berbasis IC 555 functions of each pin IC 555 • Ground, is the input pin of the source of the negative DC voltage • trigger, negative input from the lower comparators (comparator B) that maintain oscillation capacitor voltage in the lowest 1 / 3 Vcc and set RS flip-flop • output, the output pin of the IC 555. • reset, the pin that serves to reset the latch inside the IC to be influential to reset the IC work. This pin is connected to a PNP-type transistor gate, so the transistor will be active if given a logic low. Normally this pin is connected directly to Vcc to prevent reset • control voltage, this pin serves to regulate the stability of the reference voltage negative input (comparator A). ![]() This pin can be left hanging, but to ensure the stability of the reference comparator A, usually associated with a capacitor of about 10nF to berorde pin groun • threshold, this pin is connected to the positive input (comparator A) which will reset the RS flip-flop when the voltage on the capacitor from exceeding 2 / 3 Vc • discharge, this pin is connected to an open collector transistor Q1 is connected to ground emitternya. Switching transistor serves to clamp the corresponding node to ground on the timing of certain • vcc, pin it to receive a DC voltage supply. Usually will work optimally if given a 5-15V. The current supply can be seen in the datasheet, which is about 10-15mA.
