Build and install the Interface Board After testing on the breadboard and confirming proper operation the next step is to solder it to a more permanent perf-board. The board needs to be cut to fit into the bell opening.
Some coat hanger wire was used as a stand. There are dozens of better solutions however nothing else was at hand… |

uhm..the sound is quite weak for a fire alarm bell.. (if i heard it right) what if you
let the transistor drive a relay instead? that way the transistor would not be loaded that much
by the current drawn by the bell and would also let the bell have much more current driven into
it and results to a much fuller ring… =D

@sid: it sais in the description on page 4: “Fire alarm bells are 24VDC, the power supply being used is a 9 VDC supply which worked fine.”
January 12th, 2008
@von : woops.. my bad! heheeh.. i was not able to read that part..
anyways, if ever the person who wanna make of this and use a higher power bell,
i think its better to use a transistor driven relay.. ^^
January 12th, 2008
Hi Sid and Yon,
The bell would sound a bit louder running on 24 volts but 9 volts does quite good. The bell only pulls 35mA, so the transistor isn’t breaking a sweat running it and the LED. :)I think the camera must have some sort of noise leveling built in since it sounds louder in real life than in the video. If I upgrade to an air horn I will need the relay though.
January 12th, 2008
whoa.. air horn.. you really dont want to wake up dont you? heheheeh… ^^,
anyways, this is a nice project.. ill try to make one in my free time ^^,

That alarm would work better, and be more reliable if you wire in a beefier transistor, like a 1 amp Darlington, as well as a higher voltage DC supply in the circuit.

that’s exactly what my teenage son needs! however, the project looks a little beyond our skill / ability level. any way you’d consider selling one??? if so quantos? what if i got you the parts as well? long shot i know, but had to ask! thanks!

pls can anyone tell me ow to design an alarm clock module using an electronic workbench support system?
November 4th, 2008
Hi Shollar,
What is a workbench support system?
November 4th, 2008
Ah, its the same electronics workbench. u know the kind from multisim. its a design tool that provides one with all the components to create board level design on one’s pc.
Actually, its a software that allows one to draw circuit diagrams of components as one would do in the real sense of the word. its advantage is that instead of making use of real components for the circuit diagram one uses components which can be found on the software’s interface. Also, at the end of the drawing of the circuit diagram, there is chance for one to put on the power switch and activate the circuit to see if it will work.(more like simulation). I hope u get it?
November 4th, 2008
Hi Shollar,
You sure can make a clock with that. Do it using emulated TTL.

This PDF includes the system schematic.

November 11th, 2008
thanks 4 writing back. i really appreciate it
November 11th, 2008
but my project specifically involves using an electronics workbench, Alan Parekh.
November 11th, 2008
Hi Shollar,
What I was meaning is that you could “construct” that circuit within the software to make a simple clock. You would have to check to see if you have all of the components available in the simulation software.
November 19th, 2008
thanks Alan, but the problem now is that i dont know how to use the software besides i dont have the sooftware
November 19th, 2008
Hi Shollar,
Unfortunately I can’t help you there… I also have never used the software.
November 20th, 2008
Oh-Oh, Now I’m in deep trouble. The project is due for submission Dec 2nd.
November 20th, 2008
Hi Shollar,
What are they expecting you to create this simulation on if they don’t provide you with the software?
Was your initial enquiry about electronic workbench because that is what they recommended?
What are other people using for software?
November 23rd, 2008
Hi Alan,
Other people are using the same electronic workbench. But now i think i’ll concentrate on finding the circuit
diagram of a particular alarm clock module be it burglar alarm, fire, smoke, heat, pressure, temperature, car alarm
or whatsoever. After getting the circuit diagram i’ll simulate it on the software.
