This is a 10 way electronic latching switch using just two switches. Each output can be latched on and off independently. 10 Way Electronic Switch Circuit Diagram Notes The schematic is shown above, and two switches S1 and S2 are used to control the outputs. The main work is done by U2 a CMOS4017 decade counter divider IC. At switch on, C1 is quickly charged by R4 and a brief reset pulse is applied to to the reset pins of both U1 and U2. This results in U1, a 7 segment display display driver and decade counter showing "zero" on the 7 segment display and pin 3 (which is the output zero) of the 4017 becoming high. Each time S1 is pressed the clock input of U2 is incremented, by one count and the display and 4017 will cycle through all 10 outputs. A separate reset switch is not provided as the display reads the currently selected output. When the 4017 is on a particular output, for example zero, then the controlled circuit can be turned on or off using switch S2. To latch the ou...

This is a simple 10 Output LED Sequencer Circuit Diagram.This is a 10 output LED sequencer . After the last LED is illuminated, the circuit is reset. This circuit is build around readily available, low cost 10 Output LED Sequencer Circuit Diagram   Component a 555 and decade counter CD4O1 7. The timer IC NE555 is wired as an astable multivibrator that produces 6Hz clock at its output pin 3. The 4017 is a CMOS decade counter with 10 outputs. Inputs include a CLOCK (Pin 1 4), a RESET (Pin 15), and a CLOCK INHIBIT (Pin 13). The clock input connects to a Schmitt trigger for pulse shaping and allows slow clock rise and fall times (not needed in our case).  The counter advances one output at the rising edge of the clock signal if the CLOCK INHIBIT line is low. A high RESET signal resets the counter to the zero output. The circuit may be configured for counts less than 10 by connecting RESET to an output pin (one after the desired count). Thus, a five stage sequencer can be made by ...

10 Amp 13.8 Volt Power Supply Circuits Diagram I actually activated this and advisedly destroyed several 2N3055’s by shorting the emitters to ground. In all cases the transistors opened up and no beneficiary to emitter abbreviate occurred in any transistor. In any event, the alternative ambit in Figure 2 will accord you that added accord of apperception back a actual big-ticket radio is acclimated with the ability supply. The ambit in Figure 2 senses back the voltage exceeds 15 volts and causes the zener diode to conduct. Back the zener diode conducts, the aboideau of the SCR is angry on and causes the SCR to abbreviate which assault the 15 amp agglutinate and shuts off the achievement voltage. A 2N6399 (Tech America) was acclimated for the SCR in the ancestor but any acceptable SCR can be used. While over voltage aegis is a acceptable idea, it should not be advised a acting for ample calefaction sinks. I alone feel the best aegis from over voltage is the use of ample calefaction sink...

This is the simple 10 to 14W Class A Audio Amplifier Circuit Diagram. I have built this amplifier and it does sound good. It requires a preamp as it hasn't got much gain. It requires big heat sinks and a large transformer and a great power supply and careful wiring, but in the end it is xtremely simple and it sounds very good. The zener diode rejects any ripple coming from the power supply, But you still only want a ripple of 10mV max. The ripple reaching the input is amplified, so the zener diode gets rid of that, but whatever ripple there is will still reach the power stage.  10 to 14W Class A Audio Amplifier Circuit Diagram

The equalizer presented in this article is suitable for use with hi-fi installations, public-address systems. mixers and electronic musical instruments. The relay contacts at the inputs and outputs, in conjunction with S2, enable the desired channel to be selected. The input may be linked directly to the output, if wanted. The input impedance and amplification of the equalizer are set with S1 and S3. The audio frequency spectrum of 31 Hz to 16 kHz is divided into ten bands. Ten bands require ten filters, of which nine are passive and one active. The passive filters are identical in design and differ only in the value of the relevant inductors and capacitors. The requisite characteristics of the filters are achieved by series and parallel networks. The filter for the lowest frequency band is an active one to avoid a very large value of inductance. It is based in a traditional manner on op amp A1. The inductors used in the passive filters are readily available small chokes. The filter ba...

Where would we be without our infrared remote controls? Stuck back in the dinosaur era, that's where. IR remote controls are now built into lots of appliances, ranging from TV sets and VCRs to audio equipment, robots and lights. This relatively simple design makes it easy for you to add infrared remote control to your latest project or to existing equipment. What's more, it can control up to 10 different functions, which should be more than enough for most applications (usually, you'll only need one or two channels). Each output uses an open-collector transistor and this can be used to switch a relay or even to directly switch other 12V equipment. The outputs can also be used to drive LEDs via current limiting resistors or to drive optocouplers (eg, to provide isolation from high-voltage circuitry). Heavy current items such as motors and light bulbs will have to be driven by relays. We've made the job easy for you by including diagrams that show all the various options ...
