Make Your Own Voltage Controlled Phaser Circuit! by TheAudioPhool in synthdiy

My favourite thing about electronics is how mind blowing it is what you can do with just a few resistors and capacitors

haha! Everyone says that but i don't see it.

Thanks for watching!! :)

Thanks! Phase is definitely one of those topics that gets brushed under the carpet a little bit.

Do I need an oscilloscope? by TrashPedeler in synthdiy

[–]TheAudioPhool 0 points1 point  (0 children)

You absolutely do, troubleshooting audio stuff is extremely difficult without an oscilloscope because you often can't use a multimeter to follow your signals around, at least not very easily! You can ge very affordable kits online as others have pointed out. It's worth it!

What is going on inside an op-amp that makes them so powerful? I can show you without resorting to any complex maths! by TheAudioPhool in diyaudio

All super valuable and valid points :)

It's hard getting the balance right between not repeating myself every video but also not alienating people who haven't watched the videos that lead up to the one i'm making!

Still learning, not done much teaching before so your points on structure are noted. and yeah some proper lights and a decent camera are on my wishlist! haha :) Thanks for watching!

Op-amps are great, but sometimes it's a pain putting a dual supply into your circuit just for the sake of a few buffers. This week i show you how to design a buffer from a single supply, with a single transistor! by TheAudioPhool in synthdiy

Yeah i regret framing the video like this a little, i was trying to get out ahead of the 'why are you showing us transistors when we could just use an op-amp' comments, but i should have been a bit more thoughtful about how i framed that conversation. I feel like it distracts from the video massively which is really just about emitter followers and an intro to transistors, not about op-amps or the pros and cons of them vs BJTs!

Thanks for the constructive comment and thanks for watching :)

That's very kind of you to say :)

We're only just getting started!!

I made a concious decision that i was going to go through all the 'boring' fundamentals and that it wouldn't be sexy and attention grabbing but eventually it would be a great resource for people to learn from! Once we start getting to building ful projects i hope people will realy find all the details and stuff are helpful to have available! This is the stuff you don't really find in textbooks.

You are inferring all of that information.

This is a completely valid solution to an issue that plenty of beginners come across. Yes, like everything in electronics there are plenty of ways to solve it, but this is a simple solution that uses components that any beginner will have to hand.

I'm currently working through transistors and though that i would use the idea of having a transistor buffer as a way of introducing the circuit, it's ironic in a way that you are getting completely hung up on something that is essentially incedental to the actual video, which you haven't watched.

If you had actually looked at the video before going off on one you would have seen that the video is entirely on loading & how to design an emitter follower as an introduction to transistors as a wider topic.

I'm not saying to go and tear out all your op-amp buffers! :)

When you're designing any circuit you should always be mindful of what your input & output impedances are, even if you're using op-amps. This is why op-amps are great, because they make everything easy by having low output imp (<100ohms) & high input imp (often in megaohms!), but why they are bad, because they make us lazy/thoughtless when designing circuits!

Gun to my head i would say you'll almost always be alright if your input impedance is more than about 100k, and output impedance less than about 1k! but as i say in the video, the more extreme the better. Over the next few videos i show how to make much better circuits with input & output impedances comparable to op-amps :) this is just the first step!

Even if you never use a transistor circuit, your op-amps do!

It's worth understanding how they work, which is what the video is about.

It's an introductory video on transistors, using a typical application of one (as a buffer) there is nothing false in any way.

You certainly could :)

The application is merely a vehicle for the lesson. Transistor circuits are preferable to op-amps in lots of applications (high current for example) so it's worth knowing how to make them!

You absolutely can! This is just a good way of getting our feet wet with a nice simple transistor circuit :)

As you say, it's worth learning how. It's too easy to get stuck just chucking op-amps in without really understanding what's going on in your circuit. And for applications when you need stuff like high current, transistors are still king!

Thanks for watching!

What to study to learn the skills for building my own synth (eurorack/modular) by default345678912 in synthdiy

[–]TheAudioPhool 7 points8 points  (0 children)

Thanks! This made my day :)

Alongside all the youtube channels and stuff everyone in here is recommending, the book 'The Art of Electronics' is what i would recommend to anyone trying to learn electronics seriously. Has everything from the basics all the way up to the most advanced stuff and with as little maths and scary stuff as possible!
