Munky Posted April 8, 2006 Report Share Posted April 8, 2006 how those this system operate? i have difficulries to understand how it works. :-[please reply as soon as possible.....Thank you Quote Link to comment Share on other sites More sharing options...
ante Posted April 8, 2006 Report Share Posted April 8, 2006 Hi Munky,Have you got the values for the parts too, it might help. It looks like a “vox” or similar but I’m not sure! Quote Link to comment Share on other sites More sharing options...
Munky Posted April 14, 2006 Author Report Share Posted April 14, 2006 sorry, i don't have the values for the components.....by the way what do you mean its like a "vox"? Quote Link to comment Share on other sites More sharing options...
logan_dslasher Posted April 14, 2006 Report Share Posted April 14, 2006 hi Munky!In telecommunication, a vox (short for 'voice operated switch') is a switch that operates when sound over a certain threshold is detected. It is usually used to turn on a transmitter or recorder when someone speaks. It is used instead of a push-to-talk button on transmitters or to save storage space on recording devices. The circuitry usually includes a delay that leaves the circuit activated when the sound stops. This keeps the circuit from turning off during short pauses in speech. en.wikipedia.org/wiki/Voxam i right, Ante? Quote Link to comment Share on other sites More sharing options...
SM2GXN Posted April 14, 2006 Report Share Posted April 14, 2006 Hi logan_dslasher!You are perfectly right, couldn't be said better ;D Quote Link to comment Share on other sites More sharing options...
logan_dslasher Posted April 14, 2006 Report Share Posted April 14, 2006 SM2GXN, credit goes to wikipedia! ehehe ;D Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 14, 2006 Report Share Posted April 14, 2006 I think the circuit is a "clap switch". It switches on the relay when you clap your hands a few times that are determined by the flip-flops. Quote Link to comment Share on other sites More sharing options...
SM2GXN Posted April 14, 2006 Report Share Posted April 14, 2006 Audioguru you are probably right, there is no trip or holdtime to adjust but wikipedia was right about the vox ;D Quote Link to comment Share on other sites More sharing options...
ante Posted April 14, 2006 Report Share Posted April 14, 2006 That’s probably true but still the values for the parts will help to find out exactly what this circuit does! ;) Quote Link to comment Share on other sites More sharing options...
Munky Posted April 16, 2006 Author Report Share Posted April 16, 2006 Hi Ante!.... ihave the value for the components....ResistorsR1------------ 8.2 K (grey-red-red)R2, R5, R7-- 10 K (brown-black-orange)R3, R8------- 6.8 K (blue-grey-red)R4------------ 180 K (brown-grey-yellow)R6------------ 100 (brown-black-brown)R10, R11---- 100 K (brown-black-yellow)R12, R9------ 1 K (brown-black-red)DiodeD1------------ #1N4001 (Rectifier)CapacitorsC1------------- 0.022 µF (#223n)C3,C4--------- 0.01 µF (#103n)Electrolytic capacitorsC2-------------- 1 µF (10V min)C5-------------- 10 µF (10V min)C6-------------- 330 µF (10V min)TransistorQ1-------------- General purpose NPN typeMiscellaneousLED1----------- Light-emitting diode, 3 or 5mmMIC------------- Condenser microphoneIC1-------------- 8-pin, dual op-amp IC (#358 or 1458)IC2-------------- 14-pin dual D-flip flop, CMOS IC (#4013) Quote Link to comment Share on other sites More sharing options...
ante Posted April 16, 2006 Report Share Posted April 16, 2006 OK, here it is! Quote Link to comment Share on other sites More sharing options...
Munky Posted April 18, 2006 Author Report Share Posted April 18, 2006 i know the value of this each components, but the trouble is i don't know how this circuit operates or how this system work?i think this circuit is "sound actuated device" like you said...i can't sims to understand how it works actually, but i know it is a device which work by sound actuated.
