3D Spectrum Analyser (1280 LEDs) - MAKING OF

[@peplegal8253]

As an Electrical Engineer as well I need to say...IMPRESSIVE ! I'm used to design professional circuits for my company...but that is the first time I see a DIY project being made in a such high level way. And yet you play piano sublimely. Congratulation for both...Your Artistic and intellectual skills.

[@Pianistos]

+Paulo Emilio Thank you, it was a lot of fun making it.

[@honestlyidk2585]

+Pianistos wow cool

[@jbarragan]

Agree with you, I'm also an electronics engineer.

As a ME I feel like an idiot. LMAO

[@ohms5054]

lolok You might want to hide your downloaded tutorials on how to build Raspberry Pi's if your going to make pretend that you've been an electrical engineer for 45 years. And if the most beautiful build you've ever seen after all those years of experience was a homemade spectrum analyzer made from led's, than you must've been engineering extension cords in Mexico all this time. I'm not an electrical engineer and this thing he built was cute, but it's definitely not the most beautiful build. What are you a fucking idiot. Sorry, I don't like people spitting lies. Just be yourself bro.

[@ohms5054]

@@daltonanderson3457 Don't feel like an idiot. Raymond with his 45 years as an electrical engineer doesn't realize that we can see his playlists of how to's on raspberry pi's lol.

Holy shit! I have no way to express how much i love this "making off" video! The voice over was perfect, the amount of details you covered were amazing, and it was awesome to watch! Thank you! :)

[@donaldfilbert4832]

Words cannot express how brilliant this is !! What an unbelievable commitment !!

[@MW2ONLINEGAMER100]

I am completely in awe at how you did everything from scratch.. I'm currently completing a college internship and my degree is computer and electronics and I've been looking at designs for some PCB's and I was waiting for you to say "Now I have to send my design off and the PCB will return in a week or 2". I can't wait to show my mentor this video.

[@motif123456]

You are great genius, a rare combination of pianist+electronics engineer+sound physicist,hard to find /come by these days.Your explanation about exponential pitch across the piano and logarithmic function of human ear resulting into linear perception of our ""external acoustic world"" is really awesome.I cannot help but say that you are a really knowledgeable person,who knows what he is doing. I was just doing some search on the youtube , for some yiruma related videos.when I saw your spectrum analyzer placed on the keyboard, being shown in the thumbnail preview line up. I am from India and did a lot of research on how we perceive pitch and interval....downloaded some physics e books but in vain....I always wanted to know how nature works in getting us to listen to music and that was because of my love for physics since school days and later on as I joined medical school as ENT surgeon. I repeat:very nice video+very nice interpretation of the physics stuff +very nice piano playing.I was equally stunned by your industrial establishment which features laser cutter etc....really mind blowing.

[@Pianistos]

rajarshi kar Thank you for your comment :-)

[@endless4356]

***** I have never enjoyed learning about something as much as I did watching this video. I was just look for some visual ideas but once you started explaining I couldn't stop watching... We need teachers like you.. Great job ..

[@tiggstah]

holy hell man! the variety of knowledge and skill this took is monumental! every bit of it carefully thought-out and expertly executed. bravo!

[@Capturing-Memories]

That's the most advanced DIY home project that I've ever seen so far, good job.

[@andrewarbogast9313]

This was a relief for me to watch. The simple and effective video of your designing everything from scratch reminds me that we’re still out there. Those who are curious, creative and resourceful. Thank you, friend.

[@deangreenhough3479]

There is real quality in your work

[@Turtle1631991]

This is hands down the best video on making your own PCB I saw on YT. At the same time very informative for those who had no idea that is how they are made and at the same time showing DUI crowd jsut how good you can get with the process. Thumbs up sir

[@Ogma3bandcamp]

This is beyond awesome. What a craftsman.

[@nicesmile3415]

This video being over 2 years old and I just saw it today. It is unbelievable on how complex but very informative this video was! I'm very impressed to the details you've made at every step of the process of the fabrication. Still do not understand how this video has received any negative feedback. Hope that you have a great day! **Big thumbs up**

[@JapaneseModernist]

One of the most incredible videos I've ever seen! Amazing!

[@timderks5960]

So, everybody is talking about how impressive the project is. It is. What's almost just as impressive though, is the description below this video. It shows a level of attention to detail and dedication that's hardly ever seen on KZbin. Great job guys, great job.

[@TheDutyPaid]

I think it's amazing how you did everything yourself.

This is the most organized, educational and professional well illustrated video I have ever seen in my life .. I have absolutely ZERO questions. I didn't even need to repeat any part out of confusion. And the fact that this is a DIY project, makes me out of words. Thank you so much for sharing such piece of art with all of us. I am definitely making one (one day :D)

[@SimpleEnough2k9]

Simply mind blowing !!! This is an epic mixture of patience, thinking, planning, knowledge and a lot of skills. I saw a lot of project builds over the last decades but this one is in its own class. Superb work for each an every single aspect of your work. Knowing electronics and acoustics as you do is one thing, mastering them the way you do is remarkable. This is an awesome piece of work. Thank you for sharing this video !!!

[@PedroSilva-pr2ef]

My thought process: Thumbnail = looks cool, check it out Title = I love music, this should be a cool tutorial First 5seconds = that's cool, I'll make one 25 seconds in = yeah I got ebay 1:00 = hmmmm this looks difficult 1:30 = oh yeah, template... 2:30 = mmmm....expensive machinery I don't own... but there's always a workaround. Amazement at this guy's skills 4:44 = oh yeah, i've been wanting to learn google sketch up so this should be a mad project... 5:30 = oh...now he's bending perspex... this might be out of my league. 6:25 = wow look how neat it all is... yep, this is out of my league 7:00 = designing electronics... oh hell no, I'm out! 7:15 = DESIGN A PCB BOARD!!! *Mind blown* Hats off to you Sir. Awesome build. I'll just subscribe and watch instead!

[@dekoomers]

Are you me? cause I felt the same way.

[@TealJosh]

@@dekoomers This is an amazing project, but the execution was overcomplicated. With two tools, one for designing and other for generating the print for the PCB(jlcpcb) lets you create the PCB for ten dollars. Even better, the autogeneration will most likely solve the extra wiring this dude had to do to his PCB.

[@ohms5054]

I like how he explains what a PCB is and it stands for "printed circuit board" and that it sometimes has two layers. "Now I show you how to make one?"

[@shadowsidd09]

This is mind-blowingly insane stuff. I'm sure this gentleman is a super qualified engineer and certainly knows what he is doing. What I appreciate the most is the time, dedication, focus and patience that went into this project. Hats-off to you sir!!!

[@civedm]

I'm a fairly new electronics engineering student. Watching this video scared me! Holy hell. I wanted to stop watching but couldn't! I want to be at this level and have no idea how long that will take. The idea that it might be a long time is what scares me. I want this skill so bad.

[@LuminousIris]

I'm not even an electronic engineering student but even I want to do it just for fun. Plus I am really into music too and I play the guitar so that works out.

[@MarkMcDaniel]

Same here, just finished my first semester. But, a part of me would love to tackle a simpler, scaled-down version of a light array prism project.

[@TheRealJawad]

Check out some 8x8 led projects. They are simpler and doable once you understand the basics of electronics, circuits and programming. This is more of a final year project.

[@quickend01]

Pure genius, I would never be able to make one but I cold not stop watching it. Nothing could stop someone with his ingenuity and drive. I hope he continues to use his super powers for good!

[@Pianistos]

WOW, overwhelmed by the positive reactions! Thank you hackaday.com! Please share this educative video with your students, colleagues, friends.... and let me know what brought you here! :-)

[@MalCooper]

***** Very impressive. I built a simple, in comparison, 2D, 10 (octave) band, 10 LED/band audio analyzer, a few decades ago with analogue circuitry. But all the PCBs were done, all components and instructions provided, in a kit. You have done all the development, design and construction yourself. Bravo

[@eslamali6221]

+Pianistos you are the best

[@ErSedavi]

+Pianistos Very cool and instructive "Making of"! I love your build. I know many people tell you to make an "step by step" or something like that here and in hackaday.com but it's obvious that is too much work rebuild the Analyser and as you said, you have no time for this, but... Is it posible that you share the boards's schematics, the code and a list of components? Many people and I would be eternally grateful to you if you do that. Greetings from Spain. PS: Nice covers ;)

[@issacdhan]

Edited quote - The More you see , the more you realize how much you don't know. Superb project. Awesome explanation, Wonderful execution .

[@OnlyNotes]

I once made a circuit to flash some IR LEDs at 14hz. I soldered it on a store bought perf board and had to use a 555 timer circuit builder I found online to come up with the component values... and I thought I was top shit because nothing blew up. *Then there's this man* XD In all seriousness, there's some real ingenuity here. The project turned out great, this is definitely something to be proud of!

[@gyocy6820]

[@DarkVeaerxD]

Impressive. One thing I want to say is that the LED used in this project and LED's used Led Cubes projects are completly diffrent. Ones in cubes are programmable through I2C protocol. These here are normal LED's which only furthers proves your genius because it's much harder to build your own circuit than writing a program (which you also has done). Keep it up!

[@DarkVeaerxD]

And here i was too fast. Last 3 minutes of video impress me even further. Hands down.

[@VeganBytes]

Dude, all I can say is Bravo 👏 As a qualified electronic engineer myself this is something even I couldn't build. In college we all built final year projects, and every project was totally different from each others. What I could electronically understand and build was completely different to others, (and the same for them too), but this project is on a higher level than what I've seen. You truly are jacked deeply into the matrix. Very clever stuff 👍 (I built a full size pinball machine that kept score, and outputted all info to a small lcd panel) as my project 👍 and I left it in college and told my lecturer he could strip it and keep the parts lol 😆

[@chetanpen]

I have no words for your work. Thanks for letting us know, that we have not yet started anything.

[@raitraak]

Wow, nice job! For the PCB can also recommend the ironing method. Works just fine.

[@Pianistos]

In this case it won't work well. - The PCB surface is too big and there will be problems with the heat distribution. The surface will act as an heat sink. - The ironing method works only if the PCB traces are thick enough and there is enough distance between them. In this project I went as low as 300 um if I remember correctly.

[@raitraak]

Heat distribution can be resolved using heat insulator under the board. And even 0.2mm is doable. Just need the correct photo paper (not the blue press n peel stuff). But of course, if you already know how to do the optical method and have the tools, it's actually easier.

[@katherineleflufy7693]

As with most of the other comments I could not dream of having the skill or comprehension to attempt such a thing however your commentary is fantastic.

[@GRKNG]

im lost but great project man its just way too complicated for me. :) Id love to buy one though

[@sircompo]

That is beautiful. If I win the lottery this'll be the first thing I build in my new workshop! I can't decide if it'd look better with the top three rows of LEDs in red. Whilst I love the simplicity of it, I'd probably add a cheap OLED display on the top to show the values such as freq band, amplitude, effect, etc. Most importantly of all, it needs a startup effect like a 3D 'Pianistos' logo fading in then disappearing as drops of rain.

[@jimmytutoriales]

Awesome!!!!

[@nkronert]

What an insane amount of work! But the result is fantastic. Hats off to you!

[@coisasnatv]

You need like what, 1.21 Gigawatts to power this thing, right? ;)

[@Pianistos]

coisasnatv The max power consumption is about 70W if all leds are turned on at once on the highest light intensity. But in practise I only need 20% of the light intensity and only a fraction of the leds is turned on. The power consumption is less than 10W!

[@coisasnatv]

***** Thank you!

[@coisasnatv]

***** one led require 20mA for max light intensity, multiply that for all the 1280 led's, how much power do you think is necessary to lit them all?
