Sound and Electronics

[@thebaconsnake]

Clear and helpful. Definitely the best starting point on KZbin for sound generation with a 555 IC. Thanks.

[@johnsantos975]

One of the best instructional videos ive seen yet. I've purchased many classes and this is the most comprehensive video I've seen. Straight forward.

[@nojusticeanywhere]

I really wish I seen this much earlier in my journey learning about electronics. Thank you for making this. it's extremely well thought out in execution and informative!

[@dragonphoenix1881]

Thank you for a wonderful, truly educational video. You are the only one I found that explained everything. Where others say follow the circuit diagram, you went over each connection and for a starting hobbyist like me that's priceless.

[@DanielReyes-vf5de]

I've been looking for stuff like this for too long, thank you.

[@Sarahbuildsstepsequencers]

Daniel Reyes you can also search, ‘DIY audio oscillators.’

[@Purple431]

This is one of my favourite circuits! One of the best uses for the 555 timer IC.

[@Scrub_Lord-en7cq]

Shit my kit doesn't include one. How much is the cheapest one?

[@chingchong7838]

what would you need to learn if you want to build electronic audio equipment like equalisers or amplifiers etc?

[@sagiforbes5077]

Very clear an helpful. I was looking for some basic, fun, circuit to build with kids. This is right on the spot..

[@ushillbillies]

When I do finally get time these excellent tutorial videos you put out will be my life line .. Thank you...

[@erikavargasalvarado5042]

You did a great job in this video. you should really do more like this

[@TheMick26]

You make excellent instructional videos! Very informative and interesting. Thanks for doing what you do! Mick

[@SiskinOnUTube]

I just ordered a bunch of 555's the other day. I've been wanting to play with them for a while.

[@egyember4981]

6:12 - 6:16 Dolphins confirmed? :D

[@maxwarfield6699]

What is the value of that large optional capacitor, towards the end of the video. Please let me know, I want to learn. Thank you kindly

[@naderhumood]

Exellant job Sir, ....and you're great guy. Very clear....I'm sending u my regards from Bahrain..Thank you very much. Indeed..👍 following you.

[@hakeemdj368]

amazing... how a little stuffs with electricity potential in them, when arranged in such a way, could generated a phenomenon that's called sound. btw, what actually really happened in each of the electronic component? a complex process? or a simple one?

[@flyoversirens3704]

Why does a cap have to be in series with the speaker? Also, why does the polarity matter on an AC signal?

[@Thetrucky69]

This is excellent, very clever.

[@user001sg9]

Very educative video indeed. Thanks. Using two identical circuits shown in your video, is there an electrical connection between these two, or the blend of sound produced is just a different combination of C1 and R2 values in each circuit and then powering them simultaneously?

[@Estabanwatersaz]

Wow! Your great! Thank you! Keep up the great videos! Thanks again!

[@izzy5532]

Can someone explain to me why u need to use capacitors and how to calculate the resistors thingy

[@cjlooklin1914]

Basically the frequency generated by the timer is dependent on the charging on discharging of the C1, the smaller C1 is the faster this process happens so the higher the frequency. C2 is to prevent noise and or a DC level from interfering with the sounds.

[@manugira-gym]

@@cjlooklin1914 is there a way to compute the frequency f from C1 en R2 ??? I heard that for Wien Sine Wave Generator the formula is f=1/(2pi * R2 * C1) Is this a correct formula?? If I compute it with R2 = 2200, I obtain f=72.34 Hz which is a very low tone compared to what I hear in the video.

[@cjlooklin1914]

@@manugira-gym f = 1.44/[(R1 + 2R2)×C1] f = 1.44/[(330 + 4400)×10^(-6)] f = 211.416 Hz

[@weststarr2046]

Nice and marvelous video...! One subscriber..

[@BPEMETO]

What is the value of the big capacitor at the end?

[@elmunita]

yes, I want to know too please (1000?)

[@Rookblunder]

I just did a similar project this with capacitors, resistors and transistors to oscillate then added the Speaker. Does the 555 enable us to leave out the transistors ?

[@eskimoquinn4370]

Great vid!

[@arnavpanchal5217]

Perfect 👌 helped me a lot THANKYOU!

[@albertking6646]

hahahahaha

[@Mi-cha-el-Edward-Lee]

Thankyou, this was interesting to me. I wonder what the "timer" would look like in a non-"integrated" form; built of base components. I wonder what is happening in this chip.

[@dahlavibez5726]

Subscribe saved liked appreciate this so much very inspiring for me thank u

[@vintageelectronicsandamate4521]

How would I go about controlling the pitch with a small amount of variable voltage? Like the voltage used to drive a meter on a Geiger counter.

[@2bit661]

There is the LM 567 chip. The LM567 has an adjustable internal oscillator, and when it detects a match, it uses an internal resistor to send a high signal on one of the LM 567's output pins (pin 8 actually). In short, you can configure the LM 567 to control a pitch. Here is a video by a Ham Radio guy: kzbin.info/www/bejne/hZ7Oq4yegNijhK8

[@mycompasstv]

Great upload.

[@trevortjes]

How come the pitch of my tone is slightly higher than in this video? Is it because of the small difference in resistors because of the gold band?

[@poykehmusic]

Hello. What value range should the *big capacitor* in the end be? _(the one between [+] and [-] when using 2 circuits)_

[@claytonbenignus8099]

Are all speakers alike? I doubt it, but I cannot prove it from what I have googled thus far. I have found piezoelectric circuits which behave like capacitors and normal speakers that behave like resistors, according to the info that I've read. Can you do a comparison video, including how to compensate for the differences?

[@rambo8863]

How can your 555 timer handel the load of a speaker? Mine gets really hot

[@granumuse7847]

Man you're great!!!!! Thank you so much!!!!

[@wyntube07]

what size is the large capacitor at 6.25?

[@elmunita]

Maybe it's a mistery (I want to know too)

[@atierintel]

What size ohms did you use for your variable resistors?

[@thomaswells55]

can any 555 timer chip work when trying to replicate this project?

[@ImKelski]

I want to build a sound generator with a 50 khz ultrasonic frequency. What should be the value of c1 and/or r2 to have a 50 khz output?

[@DrumInfected]

Can't wait to get educated enough to finally try this. One tutorial at a time for me

[@jamesmoore9511]

How does one change the volume of the tone without changing the frequency

[@shilohlitton4793]

Do you have any ideas for how to use this "sound machine", but to take it a step further and use it to produce sound waves using water, salt or ferrofluid? We have a project due in 3 weeks. Thanks!

[@medievalspawnz]

Will this work with a 2v power source? And a smaller speaker ofc. Like.the ones in computer mobos?

[@adil.faris.1115]

this is a monostable multivibrator structure ? why this why don't we use astable or bistable MV ???

[@ozzie_goat]

That capacitor needs to go on a diet.

[@armybros8379]

Incredible

[@SheltonDCruz]

fantastic! thanks alot

[@2bit661]

Can anyone comment on this? OK, so not criticizing, but this video isn't the traditional use of a 555 timer. To get right to my concern, I am worried that this setup may be damaging to the chip over long term. I will try and explain. (And, if you look up an internal diagram of a 555 timer, my comment is going to make more sense.) Pin 7 is the discharge pin. Internally, pin 7 goes through an NPN transistor (from collector to emitter) and terminates to ground (Pin 8). My point is that pin 7 discharges to ground. (Again, this is not obvious unless you see an internal 555 timer diagram). In the video at 1:42, he pops in resistor R2 which is 2.2 kiloOhm. This R2 resistor is takes power from VCC and sends it into Pin 7, the discharge pin. This is fine. This is no concern. That is plenty of resistance between VCC and ground. (Again, Pin 7 is grounded internally inside the chip.) However!!! At 4:47 , he replaces R2 with a variable 10 KiloOhm potentiometer. That's sort of OK. But, if you twist the 10K pot down to 0 Ohms, you are sending VCC almost directly to ground. (Again, Pin 7 is grounded internally inside the chip.) I created this exact setup on a breadboard (using a 10K pot). I powered my 555 chip with my adjustable bench top power supply. And, when I twisted the 10K pot down to 0 Ohms, I could see the current meter spike up (on my bench top power supply). This is a well-made vid. Its great. Granted, the breadboarded circuit might be for temporary experimentation. If you soldered a hardwired circuit, do you think the 555 IC would damaged through constant use? (In fact, I am soldering such a circuit on a PCB board.) Maybe adding a 220 ohm resistor in series with your 10K pot isn't a bad idea. Thanks for reading this. Does anyone have an opinion?

[@mrjn6940]

could you make a lm386 amplifier?

[@dallaspilotcar9293]

thank you so much

[@poloniumsulfate2446]

How is a speaker polarised It's basically a coiled resistor used for AC (AC = no polarity)

[@JostinVasquez]

this is great i planing to be a computer enginering when i grow up.XD

[@AkashBV]

can anyone explain me why exactly Capacitor C2 is used in series with the speaker?

[@TheDiggerRocks]

The capacitor is used to remove DC offset. Basically the output will have fluctuating component (the sound signal) and a steady DC component. The latter is unwanted because it sets a non-zero baseline voltage across the speaker and therefore limits the speakers range of movement. For a good explanation see: electronics.stackexchange.com/questions/109936/what-do-capacitors-do-in-a-system-with-a-speaker

[@AkashBV]

Thanks a lot!!!

[@2bit661]

@@TheDiggerRocks That's a good answer. (I take it you relied on Google.) I remember experimenting sending in audio signals (AC signals) through the microphone on my CB radio. Without going into detail, it didn't work. (After an online search, my solution was to add a small value 10 microFarad capacitor in series with the speaker.) While I can't give a good explanation, I can speculate an answer. So, even if you look at a capacitor's schematic symbol it shows that a capacitor is not a complete path for current to flow. Even a microphone has a similar schematic symbol. In a capacitor signals aren't passed through, so much as they are electrostatically pulsed against the two plates. Likewise, a speaker needs the ability to vibrate in and out. If you take an old speaker you aren't concerned about wrecking, and apply a small DC voltage, you'll notice it just drives the speaker in one direction, probably out. The addition of the capacitor in series with the speaker helps transmit the AC signal. Sending a DC signal through a speaker just pushes the speaker outwards, rather than vibrating it back and forth. This is why capacitors are added in series.

I need to produce a sound of 32000 hz frequency can you please help me out

[@iblesbosuok]

You can use wall clock crystal oscillator which has 32768Hz resonance. Or you can use 10240000Hz crystal package and divide by 320 with TC9122.

[@swaroopkunapuli7805]

[@simpsonizer]

Did anyone know you can take an audio bipolar capacitor and probe (carefully) different chips on electronics and hear odd bus noises! It is neat as you can use old and odd circuit boards for odd synth effects! I did some cool experiments with data cards, batteries, and a simple amp! I am looking for if anyone else done this? It is safer to do with low current battery power devices! Careful they can be destroyed! This can be done to boards from VCRs to DSP sound cards! All one needs is an oscillator to activate the clocks on the boards if powering everything is an issue. Surprises everywhere!

[@johnb3023]

Neat!
