dude I have a bachelor's degree in electrical engineering and all we ever did is calculate these things without ever talking about how to design circuits and what of the hard maths is actually important. You are really good at cutting to how actually to apply these things and you deserve way more views than you have
It didn’t take me but one time of watching your video to add you as my electronic teacher.I’ve alway been a slow learner but your method of teaching makes it so much easier to understand.A big Thank You !
I've watched A LOT of basic electronics videos... I gotta say this has been one of the simplest and easy to grasp! Great work, my dude! Thanks for making this follow up.
Wow bro... I've been here for a quite some time and so far you may be the best person explaining AND demonstrating these concepts... Plus you're funny 😁 Much appreciation for all this hard work... Keep on bro!!😎👍
this is really great content. thank you! learned a lot and it was also a bit like magic watching the shapes change over the successive steps. beautiful.
That explanation is also important if your learning electronics because not only are you learning about signals but you are learning how to filter each main type. Thank you again now I know "why" this type of circuit work. Brilliant👌
You explained it well, you should try becoming in electronics teacher in the future you would do well, your circuit would be a good way to make a simple sinewave inverter 240AC.
you are a great professor!!!! i love the way you explain!!! very clear that everyone can clearly understand. 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
I never had any conception that analog audio was still so popular. I'm starting to get the idea now that it really isn't popular overall, but that there are tightly-knit and dedicated communities for it that individually are quite active, and that's neat.
AT Power supplies(Not modern ATX) used in pretty much all older 90's/early 2k computers supply Positive and negative @ both 5v and 12v. It was a requirement for the ISA BUS. The ones that have real deal open or closes power switches. Often 1/2 amp and sometimes substantially more. Cheap to free depending on if you can source some old 286/386/486(maybe even early Pentium) computers nobody wants to pay tomrecycle
Next step in your project should be the use of a single op-amp as an active filter so you can get rid of a bunch of op-amps and RC filter networks.... The best book I ever read, written in terms you didn't have to be an electronic engineer to understand, was written by Don Lancaster way back in the 70's. I have a paperback version I used to refer to all the time and would have been lost without it; but it's not here with me at the lake to refer to it right now. Since I am going to be 73 tears old, and the brain is fuzzy, I am going to say that I believe the title was 'The Care and Feeding of Op-Amps'.......; but I am not positive about the title..... . I found a link to his active filter cookbook, and many of his other 'cookbooks', but not the basic op-amp circuit one. In ant case here is the link: yzimewyh.files.wordpress.com/2014/07/don-lancasters-active-filter-cookbook.pdf .
I can promise you that you will recieve a ton of hits on your videos if you make one about creating a pure sine wave output from a modified sine wave inverter. That's why you're getting so much attention for this particular subject. Start doing videos where you tear different brands of inverters down and show where to place pure sine wave filters and you will be a youtube God.
Yeey! Thanks for the awesome videos! Small request: for future videos, could you please adjust your compressor/limiter settings a bit? Every time you stop talking, your audio gain resets to maximum and drops straight after - makes for an odd emphasis-on-first-word effect :-)
I'm trying to make it more gentle a bit but it's quite tricky. Audio processing is one of those things that's hard to do if you're not a professional unfortunately.
Very good instructive video. Thanks for taking the time to do this. I agree, a schematic would let the newbies see the whole picture, but your explanation of the circuit was the best on the net.
Thanks for uploading such a great video, I wonder if would give me some more information about roughly which values did you use for the passive components in the filters as well as which model of OPAMs and transistor did you use to get these results, please? I'll kindly appreciate it since I'm trying to do this project myself. I watched your previous video and have a somewhat idea of what you might be using, but I'll be more at ease with your reply. Thanks again and hope you're having a nice day
Hello, I must say you helped me an awful lot. I understand all the concepts but it would be nice to know the exact components values, or at least an estimation because I need to build this for a synth project I'm doing for school. Does it funtion well with frecuencies up to 2kHz?
Thank you for good video! I have a question. If I change main frequency of square wave will this schematic work correctly? I think that an amplitude is unstable because of filter's cutoff frequency
I have a 3000-6000 watt modified sine wave inverter that a want to run my RV Refrigerator while going down the road and it has 4 marine batteries to operate it ,, would it be alot of work to convert it to pure sine??
The price of pure sine wave inverters has dropped immensely. We have 2 pure sine wave inverters. One, which is only 2,000 watts (all we needed) which, 25 years ago, cost us around $1,800 then. About 10 years ago, I bought a smaller unit that is only 1,000 watts, which we use in the car when travelling, just to charge the phones and laptop as well run some LED lights when dark. That one only cost $300 new! It might be better to just buy a new pure sign wave inverter rather than trying to convert the one you have now. The thing is too, that every manufacturer has their own circuitry which can make it difficult to figure out the best way to convert it. I do have a little 300 Watt modified sine one that I got many years ago for travelling, but I don't use that one for obvious reasons. I've considered trying to convert that one, just for fun, but using an Arduino Nano to generate the sine wave at 60 hz. But this might require taking the transformer apart to rewire it a bit to get the voltages right again.
IDK if it's too much to ask, but can you put the values of the various electronic parts you use ? Like the capacitors value, electrolytic or ceramic, parts number, and so on... Still if you didn't have time, it's fine though
I do when it's relevant to the circuit, but most of the time I'm actually just throwing together whatever parts get the job done or perform the demonstration. When I do real circuits (like when I get back into audio amplifiers) and give actual working circuit diagrams, I'll be sure to give actual parts values.
I can't tell you why it's the most popular but I came here trying to understand how to change an audio signal from square to sine or triangle with eurorack.
Yes, it would be particularly interesting to see what happens when powering a transformer primary as he mentioned he will do with this project but he may or may not intend to make a video on it.
I haven't studied inverters directly yet, but the easiest way seems to be to use powerful transistors in darlington arrangement to put a square wave directly over a step-up transformer. Using a square instead of a sine is less efficient, but is much easier.
I've mentioned it in several op-amp and OTA videos, but it definitely would be worth a video all on its own. For op-amps it's really an issue only if you need really high-fidelity signal amplification, but for an OTA it's actually quite important.
I have a 3000w - 6000w peek generator that is produces a 240v modified sign. Is there a device that i can buy off of ebay / amazon that i can feed this source into that will output something close to a pure sign wave? Thanks
Just plug a lamp in the 240 plug after cutting the lamp off then with the hot end connect it to a beefy subwoofer and enjoy because it's already a 60HZ since wave
@@BlondieSL The Arduino has no real analog output port. And I doubt that it can calculate a sine wave in real time up to frequencies of 20 kHz to bring it at 200 kHz over its PWM port.
@@gkdresden I'd have to research it again, but I remember videos and code to get an Arduino to produce sine waves. It might have been the DUO board, but it's so long ago now, that I just can't remember. It was just an idea.
You would just use a step-up transformer on your final sine wave to get the voltage up to what you need, but you would need INCREDIBLY strong parts to be able to handle that kind of power. So it wouldn't really be difficult, just dangerous and a bit expensive probably.
If you need a quick and dirty way to generate +10V and -10V from only ground and +5V look at the max232 chips used to generate an RS232 +-10V signal from a 5V serial signal. I suppose that there are now better solutions to do it....
There is also a simpler way to get from the Triangle to a sine. Look at Thomas Henry’s schematic. www.birthofasynth.com/Scott_Stites/Images/multiphase_tech/th_sine_shape.jpg Oh, and you’ll probably be able to explain what it does. Keep those video’s coming.
That looks interesting, but it's definitely a bit beyond my ability to just glance at and understand. I'll be sure to look it over and see what I can learn from it though!
