555 timer bomb timer sound maker

[sajten]

First of all, bombs doesn't beep.

[MrGreyhoundz1]

WHY IS IT CALLED 555 TIMER BOMB?? IS IT BECAUSE IT SOUNDS LIKE 555.

[Diddleshot]

I wired a stepper motor controller when I was 15. See if you can do that.

[swedensy]

Not much of bomb timer sound maker couse you have to do it manualy. (idk what guy gonna do that)

[stahlight]

Helluva good job man! I started when I was 13, went on to get my Masters. Ya got to start early to be the best! Also if you want to make more fun sounds, look on ebay for a SN76477 sound generator IC. You can do the beeps and the kaboom with it :)

[powermaks]

it looks like what you did was have one adustable 555 chip control another and created a pm wave the second 555 was the high piched beep noise while the first 555 controled that.

[XftumchX]

You should have just used a piezoelectric sounder. That would have negated the need for a second 555 ic.

[krieglight2411]

dude! can you PLEASE send the schematic of this thing to my email? krieg_light2411@yahoo.com.ph much appreciated! thanks! and dont forget the list of components! thanks again!

I love how all of these kids who are just getting into electronics are posting here going: Hi, im 1- how did you build this so i can build it myself, shot it to my parents, and tell them i figured it out myself.

[davidbball13]

@jbat3535 read the description.

[jbat3535]

@davidbball13 Oh no, I don't need building instructions, nor am I interested in making a circuit like this, I'm just saying I find it funny all the little kids in here.

[dnanodesign]

hey, can i have a questions about non inverting amplifier with operational amplifier? because i have made one on my breadboard and i got stuck by have no change of my output. thanks

[happygamestvfun1]

why would a bomb make that sound, would it not just give it away...

[CheezWhiz127]

Hi, I'm 13.

Can I possibly get the schematic for this?

I also like electronics and like the media side of it as well.

[Kpilot786457]

im 10 and i also love tinkering with electronics. i have been collecting electronics for a while now, and i have a few things. i am going to go to radio-shack and get more. i am also going to get a breadboard sometime. i am going to have my first project be a 555timer flasher led. then, i am going to make a 556 timer chip circut when i know how to use a 555 timer chip correctly. I have a electronics book, i have learned much from it too. i hope for you to give me tutorials to help me!

[Colekinseriscool123]

Make a schmatic

[purplemutantas]

Very cool. I should get a 555 to play with. I haven't played with one since I took electronics in high school those many years ago.

[nahonix13]

KABOOM!!

[man13preet]

any circuit for this?

[kopaszss]

gesundheit :)

[samanthms123]

nice to meet you !! i am 14 and i also have a great passion for electronics and tech.

btw, the same exact circuit is in the book "Electronics for dummies"

and the values for the pots are 50K and 100K..

dont remember the value for the caps and resistors..

[davidbball13]

@samanthms123

good for you man! I'm 15 now. I don't really mess with logic IC's anymore. Mostly AVRs. But keep it up. It's a lot of fun. I didn't use the book. Nor do I have it. I wish I had it when I was doing this stuff. I just read data sheets like a boss and did a lot of thinking

[Chewytube1]

@davidbball13 Yea, I did this same thing with an Arduino. I was just missing a knob, just programmed it in.

I was mad at Radioshack; They don't carry 7segment decoders any longer D:

[happygamestvfun1]

@samanthms123 you need the book "electoonics for dumm kunts"

[samanthms123]

@happygamestvfun1 - cool.. your cougar mom's probably the author of that book you balls scratchin gay fuck !

[madamerotten]

@samanthms123 You should probably hyphenate "balls scratchin" and add an apostrophe to "scratchin," so that it ends up as "balls-scratchin' gay fuck." Just sayin'.

[fabiuh991]

12yr old? oO

[davidbball13]

@fabiuh991 I was 13 at the time. haha I'm 15 now. Doing embedded systems.

[HowBoutDemBoyzz]

@davidbball13 thats awesome, how did u get into that id be really interested?

[fazolettino]

schematic please

[davidbball13]

read description

[j1crx]

it sounds like the wheel on price is right

[ferretco]

he died lol

[PigsCanFly99]

did you fart at the very beginning video .. probably not an inappropriate lead-in .. where's your fool schematic son? Explaination FAIL- for not providing us with a simple schematic . I get the impression you're trolling for compliments - are you? You got to do better than that. Full marks for the fart - zero out of ten - for the explanation.

[davidbball13]

haha woah...I did not fart I think I was clearing my thought. And I uploaded this video almost a year ago. I am doing embedded electronics. Mostly the avr microcontrollers. As for a schematic. I made this circuit up. Just by fooling around with the 555's I will try to put a more descriptive description up. Thank you though for letting me know about the lack of info. I now see the lack of info for others.

[davidbball13]

Actually about one and a half years. I updated the description

[Greenselves]

ok

how do you plug the ic Clock to the sound maker??

[davidbball13]

I used one NE555 to turn on and off another NE555.

[Greenselves]

great!!

what do i need to conect the sound maker?

[davidbball13]

I just used an old pc speaker

[Naarden4ever]

if you make this completely automatic, would you PLEASE add a led as a bomb to it?

(use arduino!!!)

[davidbball13]

Really, Run away from the Arduino. Fast. It's not a very good platform to work off of. The code is in C and is based off wiring which in not very productice. I've been using AVR microcontrollers which are the actual processor in the Arduino. They are much cheaper and you can make much much much more inexpensive and Space saving designs with the.

[solidacid1337]

the arduino is great for beginners. but i do agree that pure AVR is better :D

[Ryuuken24]

Where could I get the schematics for this ? Thanks!

[zimtower]

Alalalalalala!

[JASD557]

Electronica Barata......

[lucasmontec]

"Terrorist wins!"

[davidbball13]

haha I was just playing CS and made the connection

[AdamuSensei]

is that just one 555 astable driving another?

[davidbball13]

correct. you can change up the pitch of the sound maker 555 to make it sound like a truck backing up. or a fat person

[snarfalopogus]

where can i get that switch you use to alter the voltage

[davidbball13]

That is called a pot or variable resister. Radio Shack or mouser or digikey has millions

[libed91]

u can take it out of any speaker system XD

[illusionkid54]

a resistor doesn't alter voltage, just milliamps: V/R = I

[dmburke917]

But there is a voltage drop across the resistor...

[Madmax1541]

It's ok mate, thanks for the info.

[davidbball13]

and for the caps for the noise make one the cap is a 2.2 uf and the trigger 555 is a 22 uf

[Madmax1541]

Thanks for the response, i will be very pleased if you post the Resistor values.

Best Regards

[davidbball13]

yeah i think for the 555 that turns on the other 555 R1 is a 1K and R2 is the 10. the other 555 is R1 a 1 megaohm and i dono the other resistor or caps

[Madmax1541]

Hi, what things do you need to do this Project? Best Regards

[davidbball13]

two 555 timers i dont exactally rember the resistor values but i could look into that for you. a breadboard or perf board speaker 10K pot

[dmgeltigre]

What the fuck? This shit sucks gay ass! Why would you want a piece of shit like this to detonate a bomb??? It explodes as soon as the output on pin 3 dumb ass! What?  Are you planning to set a bomb and then set the interval so that you disintegrate next the bomb as soon as you plug it in??? DUMB ASS!

[davidbball13]

shut the fuck up kid. it says "555 timer bomb timer sound maker" does sound make ring a bell fuckin retard. and what you are like 26 27 get off you ass. quit that think you call a company that makes synths "that i have never seen before" and you are talking to a 13 year old who just started electronics. i bet i fucking make more money with my lawn mowing jobs. stop hating on macs (they arnt that amazing i know im not that big of a fan) but micro$oft is 10 times worse. use linux aight.

[AdamuSensei]

lol

[CrzyCuber]

the thing that u twisted and made it go faster

[davidbball13]

it is a pot or variable resistor

[CrzyCuber]

what pan was that?

[davidbball13]

???????????

[Sparrow338]

Ahah, Nice Job!

Reminds me of the bomb noise in the Counter Strike computer game. lol

[davidbball13]

thats what i was going for

[DarthHadeus]

Nice....

BOOM!
