#SUPER LOUD ALARM CLOCK GENERATOR#

Most high db alarm contains a tone generator + reed switch (magnetic switch which activates/deactivates when a magnet is placed near it) + a chock( which is basically a step-up transformer which boost the input ac signal by several magnitudes) + a high db piezo buzzer plate + power supply batteries( normally some button cells for space saving) So what we are going to do is to boost the normal voltage to higher voltage and then use it to drive some high db buzzer. also the normal buzzer inside these alarms are not designed to give high db ( volume). But since the whole thing is powered by single or double AA /AAA battery, the voltage is about 1.5-3 volt normally, and it is not enough to give a high output volume from the buzzer.

The clock's circuit ( inside the mechanism assembly) will trigger a contact/electronic switch on the preset time which opens an electrical signal ( may be even tunes) to the buzzer, which then causes the buzzer to produce corresponding sound. Normally every alarm clock, whether it is digital or analog, have a power supply, which may be from some battery source, and then a clock mechanism ( digital circuits for lcd/led clocks and analog for analog clocks ( here i use a cheep analog model, but this can work with almost all digital or analog models), and a buzzer (marked as BZ) to produce sound. you can make it even louder.ġ) Analog / Digital alarm, any model can do the trick, as long as it have a piezo buzzer as alarm speaker.Ģ) 90-110 db door open alert buzzer ( in fact any high db alarm- like those from personal protection alarm can work) like the one shown in picture.ģ) simple soldering skills( lil bit electronics skills needed if you want it make more louder)Ĥ) Philips screwdrivers for opening things, super glue, and essential components and wires. So whats the solution? of-course we may get up if some one drops a grenade near our bed, but since a grenade is pretty hard to find on local stores and worth lot of money for daily usage, i present a little hack which can do almost same.īe warned before you proceed, this little sucker is so loud, that you can wake up your buddy next door.and the evil thing is. those bed bugs ( like me) who don't want to get up from their bed, no matter how much the alarm screams., who doesn't even hear an alarm.
