555 Timer With a Speaker

[HUSTLEBANE]

what about pin 3???

[locutusofborg25]

@HUSTLEBANE pin 3 goes to the speaker

it's good to see a woman in electronics... i hope you can help me out with my projects :) i have just subscribed :)

great video. I believe there's something about pulsing 8hz and 432hz signals into something like that and using a bifilar pickup coil transformer to save the back emf. sorry if this is a random comment, just thinking out loud.

i wish you could be more descriptive of which pins from the POT you connecting the resistors and to the 555 chip. I have been trying to run this circuit for hours now and nothing is working. I am an Electrical Engineer and I have tried to follow your instructions and schematic and nothing is working. and yes I do have ALL the correct components I just wish you would be more descriptive other than saying '...put this into ONE of the pins on the POT'. please tell me exactly which pins.

@hyperscitic92a How could someone who has an electrical engineering degree not understand how to build this simple circuit?

[hitachi088]

@madamerotten he's certainly not.

[hyperscitic92a]

could you possibly tell me where exactly you are placing the potentiometer? and also could you possible post your schematic in our description?

Thanks

You are one cool chick! Great work.

1st of all a girl doing electronic stuffs thats way cool. not many girls whr i live do that they are so boring :-) btw y not jus connect the speakers directly to the battery...? it will produce the same sort of sound rite of course u cant bend the signal... with having jus one 1.5 V battery...? well i use to chk my speakers like that. thanks. m not that good in electronics jus an hobbyist :-)

lol chasm :)

Girl, You Are Greath

congratulations

Replace the speaker with a power transistor and connect a power supply and ignition coil through the transistor to produce several kV.

[gonitronow]

if you exchange the speaker with a high power transistor and hook that transistor into an ignition coil and 12v power supply you can produce really really big electrical arcs.

i'm an electronic technician and there's not many women in that profession, so it's great to see you

[imasupereagle]

To tell you the truth it really dos matter which IC chip pin is conected to the cap to ground. with IC chips you might not use all of the chip pins

hi Guxy, congratulations I know girls that likes electronics too.

in ur 1st schematic something is wrong, the potentiometer must be beetwen pin 6 and 7. if u want to amplify the sound u have to use a transistor.

bytessss.

sorry for my english because i speak spanish.

Great video.

check out my new project using a 555 timer.

[envalid]

great video, the schematic looks helpful. This is a good diy circuit for my laser gun prop, i needed a laser sound effect. :)

very nice work CR4news
