Posted: Tue Oct 18, 2011 7:25 am Post subject: EI clock chime

Bob and all, I have a EIectronics Intermational clock that will ground a line when it reaches 0:00. I would like to hook a chime to the line and run it to my audio panel. Other than EI’s tone generator, is there an easy way to do this?  

   

Thanks

    "Easy" is difficult to quantify. How handy

    are you with the soldering iron?  In the

    audio systems chapter of the 'Connection

    I illustrated a variety of tone generators

    that could be adapted to various functions

    in the well appointed airplane.



    The SIMPLEST solution is an 8-pin PIC

    uController with some pretty rudimentary

    software. This approach could do about

    any sort of 'noise' short of a string

    quartet. The schematics I illustrated

    are less versatile but can be fabricated

    from rudimentary parts.



    What would you like to tone to sound like?

Hi Bill,Â 



I used this line from the EI clock, but instead take it to a light on the annunciator panel (design as supplied by another lister here). Â It lights up a green 1 x 1/2" or so LED array. Â

Bob, I’m thinking a ding dong sound, nothing that would startle you. I will take a look at the Connection tonight. I have no experience soldering boards but would like to learn.  

   

Thanks

Here is a circuit by Forrest M. Mims, III that makes a tone when the input goes low.

Joe, that's a circuit I might be interested in for another application, 

but I don't see a power line? Can the tone be automatically shut off 

after (say) 2 seconds?

Peter,



  I'm not Joe, he's much smarter than I am, but the "power line" you're looking for is 

inside the drawing labelled "  ENABLE     (Low= Tone)  "

I am not really smarter than Mike Welch.  But I am better looking.    

The 74LS368 is powered by 5vdc connected to pin 16 (labeled Vcc).  As for automatically shutting off the tone after 2 seconds, another circuit is required for that.  Perhaps something like this "One-Shot Tone Burst" circuit: http://www.eleccircuit.com/one-shot-timer-use-ic-ne555/

My favorite electronics book is "Engineer's Notebook" purchased in 1980.  Although some of the ICs are no longer available.  http://www.amazon.com/Forrest-Mims-Engineers-Notebook/dp/1878707035

The circuit that you use depends on the signal source, whether it is steady on or a pulse.  I agree with Bob N that a microprocessor will do everything.  Its circuit has the smallest parts count, will sense inputs and (if they meet certain conditions) will output the desired signal for the required time period.  If one does not have a programmer, buying that will make the project more expensive.  And it will take LOTS of time to learn how to program.  That cost of time and money can be spread over several projects.

I believe "ENABLE" is the ground and "Vcc" is 5VDC. When your clock goes 

"low" it connects to ground and makes the circuit to activate the tone.

Thanks for that! If I were to put a pot in place of the 220 resistor     would I be able to adjust the volume? Also if I wanted to drive a     600 ohm load - ie an aircraft audio system - would I increase the     value of all the resistors by a factor of 75, or would that affect     the frequency of the output?

     

     Is the actuated by the down going edge, or because there is a     potential difference between enable and Vcc? We used to call thatÂ      ac or dc coupled, not sure if that's the correct use of those terms?

I've found the datasheet for the 74LS368 here,     looks like they require only a 5v supply and input voltage, and so I     guess only output 5v also - not sure how that will drive my audio     panel ...

John,

  Got it!!  Thanks for the explanation.  Nice easy circuit.

 I believe "ENABLE" is the ground and "Vcc" is 5VDC. When your clock goes "low" it connects to ground and makes the circuit to activate the tone.

Re: Gated Tone Source

I would not change the value of any component unless you intend to change the tone frequency.  The speaker could be replaced with a pot.  And a capacitor between the pot and the aircraft audio system will block DC.  Bob's advice is needed here.

Bob, working on the two tone generator in the ‘Connection, what is the resistor that is between the two timers? Is it 220k ?

Bob and all, I have a EIectronics Intermational clock that will ground a line when it reaches 0:00. I would like to hook a chime to the line and run it to my audio panel. Other than EIs tone generator, is there an easy way to do this?

    



    "Easy" is difficult to quantify. How handy

    are you with the soldering iron?  In the

    audio systems chapter of the 'Connection

    I illustrated a variety of tone generators

    that could be adapted to various functions

    in the well appointed airplane.

 

 

 

    What would you like to tone to sound like?
