Hello everyone,

Okay, so basically I have modified a small battery powered clock to use a smoke detector speaker. It is super loud and could possibly be used as a device to reanimate the dead. Please keep in mind this is my first Instructable, so just bear with me. Let's get this started!

Step 1: Things you will need:

1. cheapo- alarm clock. it cannot be a clock-radio, it has to be a simple, beeping one.
2. old smoke detector. we just need the beeper (I don't know the actual term for this type of speaker)

1. Flat tipped screwdriver (or other tool for prying)
2. Pliers
3. Soldering iron, with solder, of course!
4.work station (optional)
Actually, The Americium isn't 'intense' so to say, enough to give you radiation poisoning, you could actually ingest it with almost little consequence
Americium is an alpha emitter, which can make it quite dangerous if ingested. It's harmless otherwise, though.

except that it is a bone seeking radiation source- it doesn't pass through you, it builds up in your calcium deposits (bones/teeth)
Yah, I probably receive more radiation at work. I work in a shop that build power generator (~150 kV) for XRAY Tube. And I have to test those generator on real tube before shipping them.<br />
This does not work :(<br>The new speaker will just play the same sound as before...not the loud beeping noise of the detector.
its not a speaker...<br>its usualy a motor using a special blade to cause a high pitch noise... or if u are lucky, a speaker
i must test this :P im a heavy sleeper :(
it does not work :'/
Yay, for Google Chrome!
I don't see anything special about Google Chrome. My personal and preferred browser is <a rel="nofollow" href="http://www.maxthon.com">Maxthon</a>. (By the way good instructable)<br/>
Well, in my opinion Google Chrome is best. Of course, that is just my opinion.
I agree with TyMan201 Google Chrome FTW!!!!!
Well... I guess I can give it a try.
do it! simple interface, nice features, easy access... yeah...
i use google chrome since its launch.. i even did the countdown to its release and i'm totally satisfied<br/>before it i used opera, which i now use for my website accounts =D<br/>
100% Chrome.. Simplistic, Powerful, and a lot of nice easy-to-use features
&nbsp;Well Google Chrome is good, but if you need a plug-in you have to install. Maxthon is still my Browser but, I now say good things about Google Chrome.
&nbsp;How is google chrome related to super loud alarm clocks?
&nbsp;It's not, but if the author could let it slide and even join in the discussion, surely you could cut us some slack?
Urgh, I'm not too keen on Maxthon, it's just a rebranded internet explorer with a different interface.
My advice, don't do it !!! True, the alarm will be louder and you will surely have a heart attack ;-). But, the smoke detector use this kind of beaper to protect you in case of fire so YOU WILL WAKE UP in the middle of the night. But if you get used to this sound because of you alarm clock, the possibility that YOU WILL NOT WAKE UP in case of real fire are gravely augmented. So, if tou die because you didn't wake up when your house was in the proccess of being reduce to ash, don't blame me, I told you.
then in that case, you can bypass the risk of radiation poisoning and <sup> that, just buy a different, still loud speaker from radioshack</sup><br/>
Nah, I use my computer. I put a good MP3 on sheduler and with my sound system set to a loud volume with the sub on maximum power. Really, this is what wake me up. I have two set of speaker, one by the computer and the other right under each side of my bed.
Since the "Off Button" is one the computer, I really have to wake up.
yes, but that uses more electricity than being in standby mode, and we cant have that.... can we?
Even in standby mode, my laptop wake up when a sheduled task need to be done. All computer do it. If you have a antivirus with test sheduler, try putting the shedule every night a 3 am. The computer boot a start the task. It's only when the computer is off that the sheduler don't work. The power suply of my laptop is only 65w so in stanby mode, I should not take more power than a clock, but I never verified.
Your laptop is quite energy-consuming - 65W at standby?! That's level of desktop. But you can put your computer in hibernate - that consumes 0W and you can still schedule it to wake up.
&nbsp;Desktops use about a minimum of about 200watts to operate, up to 1000w, that is inaccurate, check your facts.
No 65 W at Top Level, I said that in standby mode (A.K.A Sleep Mode) I should not take more power than a standard bed clock
Gojira's Oroborus is perfect. As soon as it goes off, I'm jumping off my bed!
I play Sandstorm by Daurde
I usualy play Scooter - Hello (Good to be back) from album Excess All Area.
i would find the pin that sets off the alarm then solder the wires to that
This can also be done by soildering the wires to the &quot;test&quot; button inside the fire alarm. That is a little easier to find because it's rite behind the the outside&nbsp;button when you take the alarm apart! Hope this haleps and makes it a little easier for people . They are great i've used one for years! LOL&nbsp;They can upset the neighborors tho!!!!!!!!
My major concern with this project is that it will condition the heavy sleeper to the fire alarm sound. I am a very heavy sleeper, and when I get a new alarm clock, it works well for a while, but eventually I become conditioned to the sound and sleep right through it. I think the fire alarms should be a distinct sound that is never heard unless there is an actual fire so that it is as likely as possible to wake you up.
I had the same concern when I first read this. I think it uses the alarm sound from the clock, and just makes it louder. <br />
make sure you get one that makes a DIFFERENT sound than your real one and you should be ok
thanks the instructable will finaly get me up in the morning.
It's the almost little consequence that worries me!!!
2 things. 1: it's called a piezo buzzer 2: the amount of radiation is far less that what we get from just walking outside, I believe it is less by a factor of 10 or so, and it is encased in aluminum, so you could eat it and still not get any effects from it.
This could be great for college, just wire the clock to a bulhorn and you'll wake up everyone on your floor! jk, but seriously I have and old alarm clock and this really annoying noise maker that both ran on 9V batteries so I may try this. Nice work for a fist Instructable.
thank you. i was going to attach a car horn to it, but I couldn't do that because a car horn runs on 12v dc, and the current put out by the speakers is in ohms, whatever that might mean.
ohms are the measure of resistance volts are a measure of power
Current is the amount of electricity moving.<br/><br/>Voltage is 'how fast' the current will move.<br/><br/>Current x Voltage = Power (watts)<br/>
Cascade fail?<br/><br/>Voltage is more like pressure. Take the water pipe analogy: Voltage is like the water pressure and Current is like the rate of flow.<br/>And to clear everything up:<br/>- Power is the rate of Energy transfer, Joules/Second or Watts<br/>- Energy is the work being done, Joules<br/>- Voltage is energy per Coulomb<br/>- Current is Coulombs per second or Amperes<br/>- Resistance is the voltage dropped per Ampere (V=I*R), measured in Ohms (&#937;)<br/><br/>Things like speakers have an impedance which is also measured in Ohms but it can't be considered an Ohmic resistance because V=I*R doesn't hold linearity.<br/>
The old Water pipe analogy :) very well explained.
thats what i use to explain to friends
Yeah me too. its a pretty accurate analogy.
