@@MoritzKlein0 Your videos are absolutely worth hearing someone breathe. You're a far cry from Darth Vader 😝 That said, I have noticed some of your videos have distinct breathing while wearing headphones. I would guess it's because your camera is very close to your face to get the kinds of "point of view" hand shots you do. The least annoying way to fix this is to get an external microphone if your camera supports it. Just a cheap dynamic lapel mic with a small foam wind filter will do a lot to cut out breath sounds, as it's far more directional than the "one size fits all" mics most cameras have built in. Most will record that mic directly with the video so you don't have to fuss with editing or try to sync up an external mic. Your videos have been so helpful for me, I hope this helps you!

DO NOT attach the battery to the strap until the other ends are in the breadboard already - it's not bad with 9v, but if those exposed ends touch, it can cause sparks and damage the battery. If you don't realize it's happening, a battery can catch fire in your hand. Similarly when you're wiring up ICs - do the power LAST. In the video you did it first, AND you had the battery connected. So that amp sat there powered up for a long time with no indication that it's happy. If everything else is connected, then you power up, you'll be able to see if things are working right and disconnect the battery quickly if they aren't. DO NOT wire up breadboards with the power connected, always power up after you've finished the wiring. With low DC voltages, you can get complacent about this and end up shocking yourself or starting fires when you work with higher powered stuff. DON'T get into the habit of working with live circuits.

Very good for beginners, but with one exception. You are connecting signal leads while the chip is powered! Fine for an experienced engineer who is careful and knows what he's doing. But for a beginner, much better to disconnect the power (batteries) until after the rest of the circuit is wired and checked. A mistake in wiring while power is on could result in burning out a component.

6:38 THANK YOU FOR SAYING THIS! The most challenging part of getting into DIY electronics is that circuits are laid out wildly different than you learn them in school. I spent the first few years (and still occasionally do) wondering how the hell I was looking at a closed circuit, and then you throw in AC circuits and it gets even more confusing. So much information is implied, and I'm still learning what that stuff is, thank you for including it in this video!

I love this because many people (ME!) might be too afraid to ask about this basic knowledge. There's a lot of assumptions that everyone knows this stuff already. You have a great way of explaining WHY some of these electronics work, which gives me a better understanding how to use the tools to do what I want them to do! Thanks!

You know I'm watching every your video and I forgot to say that I like your hand-drawn graphics a lot. This bread board basics picture looks like an illustration for a good printed book. The other illustrations are great as well. It makes a feeling of some good old 1950s electronics book or something like that. I like such books a lot. retrofuturistic design

This channel is so cool, as an electronic engineer who has done countless tests on boards, love the aesthetical presentation of electronics

Greetings from Glasgow. I haven't actually used bread boards since my college days back in 1991. I needed to watch this video. And I'm glad I did. Thanks for making it. It's amazing what information brain cells retain, when I thought it was gone forever.

Fantastic video! Just wondering about the audio jack output... why do you need a "10K/1K voltage divider"? How does that make it line level? I've seen some audio sockets (for like, an Atari Punk Console) that have a 10uF capacitor and a resistor attached (instead of the voltage divider). Does this serve a similar purpose?

@MoritzKlein0

3 жыл бұрын

the capacitor/resistor combination is AC coupling the signal (centering the waveform around 0V). the oscillator in this video is producing an already-centered signal, so that isn't necessary. the voltage divider is just shrinking the voltage swing down. the oscillator will produce a signal that's very loud (going from -9 to +9 V). the 10k/1k voltage divider will quiet that down to +/-800mV (which is about consumer-grade line level)!

PSA: be really carful with batteries as well, and never put batteries of different brands or different charge levels(check voltage with multimeter)in series. Also, make sure the wrapper isn’t scratched, so as to not accidentally short it. I have had a NiMH battery explode on me and burn my skin, I was pretty lucky it didn’t hit my eye. I don’t think alkaline batteries can explode, but they are technically sealed pressurized vessels, so be careful.

I have a LM324N and thought this circuit would work with it, but it didnt. The simple inverter circuit had odd behavior. The LED would not come on unless pin 2 was tied to the Vcc- rail, or unless pin 11 was disconnected.

Thanks

This video is just what I needed. One thing that kind of puzzled me was how you hooked up two batteries. Could you just use jumpers to the other rails? Or is that bad?

Just fried my SM47. I'll try this again later.

Can you make more like this? with like a progression to more and more complicated circuts and concepts?

Warning, there are cheap and expensive breadboards. They look the same but they are not. Cheap ones use cheap connecting grips, which are not always making a solid connection with components with thin legs, typically with the very popular 1/4W resistors. Othe advise is to avoid any diagonal. Always right angles and limit number of crossings.

Hey Moritz another quick question : do you know a guide where we can choose a multimeter for this precise use (audio) ?

Thanks once again :)

This is a great video on breadboards. Thank you for recording it. I am fairly new to electronics and have two questions on one part of the video: 1. At 12:12 you use the terms neutral, ground and negative sort of interchangeably. Are they truly all the same thing? This has always confused me. 2. You then add a second battery (in series with the first and doubling the voltage) in order to connect its negative terminal to the upper rail. You say you do this so you have a 2nd negative rail for the upper section. If that was the only purpose for the second battery, couldn’t you have simply used a jumper from the lower negative rail to create the upper negative rail? Or, was there some other purpose for the second battery?

@matthollandsf

1. using neutral and ground to mean the same thing (or using the term neutral at all for that matter) is pretty unusual in this context. typically you'll hear the term neutral to refer to the return or negative pin on your wall socket (which eventually connects to "safety" ground in your breaker box). I don't believe he uses negative interchangeably here? 2. You have to understand that all voltages are relative. The 9v battery in isolation has a positive terminal and a negative terminal because that is the measure of energy a positive coloumb of charge must expend going from the negative to the positive terminal. Think of it like a flight of stairs. You expend the same amount of energy climbing a flight of stairs regardless of whether you start on ground floor or the 30th floor. We've already labeled the first batteries negative terminal ground, which is to say this is our 0v reference from which all other voltages are measured implicitly. So in our flight of stairs analogy, we've added the first battery and called its negative terminal "ground". In other words we've decided that the bottom of that flight of stairs is ground floor (regardless of whether it happens to be floating in air!). Now when we add the second batteries positive terminal to ground, it's like we've built a new lower flight of stairs below our arbitrarily chosen ground floor. We have a basement now. We connect the negative terminal of the second battery to the other rail labeled "negative" so that we can connect other circuit elements to it. Hope that helped.

I have a question about LED circuits. I know that one side goes to 9v and the other to ground, but which side are you supposed to put a resistor on? I know in this video it was on 9v, but some schematics also have it on ground. Edit: another question i figure i might as well ask now: What's the difference between voltage and current? and do resistors affect current or voltage?

@MoritzKlein0

3 жыл бұрын

it doesn't matter which side you put the resistor on - it will have the same effect either way. this is because the resistor is limiting the current ("amount" of electricity) flowing from the positive to the negative terminal. and for that, it doesn't matter where the bottleneck is! as for the difference between voltage and current, i'd recommend you check out the first episode in my DIY VCO series, since i explain exactly this in detail there!

In electronics there are components that considered as current or voltage (constant) devices.Leds are current devices and there is not fixed operating voltage nor current.So must check each led with a variable voltage source to check when it lights up in a normal level and then measure the applied voltage and the current that led draws.Size,scheme,colour,smd or not,each led type has it own characteristics.Resistor can be connected in any of the led pins.

Very nice tutorial. I have only one note: it is bad practice to do connections or alterations on the board with live power. Power should be disconnected. In one moment of the video it is clear that you accidentally shorted two pins. That is common so the reason of disconnecting power.

Ceramic capacitors are also "microphonic." That is, if subjected to pressure or force (like tapping), they will generate a small voltage. It's not usually a big deal electronically, but if the goal is high fidelity, random transient voltages in your analog output aren't helpful. That's part of the "distortion" Mr. Klein illustrated. (edited for clarity.)

why are foil caps generally preferred in audio circuits?

maybe a stupid question, but since you say here that batteries are enough to power the breadboard for these basic cases, when do you think a PSU like in your DIY PSU video starts to become necessary? in other words, both for safety and financial reasons, i'd prefer to use batteries initially (still a complete beginner). but i'm trying to understand the downsides? is there something to be wary of when powering audio circuits with batteries? also considering that apparently modules run on +12/-12, how are 9v batteries enough?

how would you make a negitive rail with something like the hw-131

Wait...what multimeter measures "the amount of current flowing"?

there are two types of charge carriers positive and negative. positive current is defined as the direction of flow of positive charge. in the wire, the charge carriers are negative (free electrons), and so the current is positive in the direction opposite their direction of travel. if you were to look inside the battery you'd see positive charge carriers (ions) moving in the same direction from positive to negative.
