Your videos just keep getting better
+MOVEMENT Thanks
GreatScott! Hello, I love your vids! I am a young electronics tinkerer and your videos really help me understand how things work better. I am currently working on a maker fair project for the mini maker fair her in Minnesota and was wondering if I could use your design in my project. If so how would you like me to credit you? Thanks!
Wow ! I'm in the 2nd year of my apprenticeship in electronics stuff, and your videos are so helpful !
Yesss! I have so many vu meters, but never get tired of them. the lm3915 it is a very good option but lm324 it is good too. thanks for this excelente video my friend!!! saludos
Como gusta verte por aquí Gastón :)
Yo también esperaba un lm3915
+maletil Essentially, an LM3915 is a single chip with coparators inside.
OMG VU METERS ARE BOSS! I LOVE THEM! I HAVE ANALOG AND LED. Sweet! I'm not the only nut! I have a ton of old stereos from sansui to Marantz and Yamaha and Sherwood!
You could also use the lm3914 for a Vu meter .C.
physics 12 student here and also not that smart.. but we are currently trying to do this project and have no ideas on which resister to use and where to use them! hopefully anyone can help? we bought all the resistors @greatscott mentioned in the description and are desperate to know which goes where
Whenever I get bored,I used to watch greatscotts videos.. It's truly awesome.... Thumbs up man.. You're great
Even though I've only taken a few electrical engineering classes, I can't help but be a little happy that I do understand most (not all) of what he's talking about.
I like the layout of the boards you make it so neat and clean
You know you're already a pro if you can place LED's and solder them neatly in just over half an hour. That would take me almost half a day just doing that lol. Great content would like to see more LED projects :>
Once again Scott, great video and thanks for the knowledge. Greetings from Brazil.
Scott you are a real profesor !!!!! "its prery simple" he said ....
Scott, du ist einer der besten UA-camr. Awesome!
this is so weird? yesterday i was looking for a LED VU-meter and couldn't find a simple / easy to follow design then you upload this a day later. awesome!
+AranE Games Cool!!!!
+The Master Gamer SWEDEN ( ͡° ͜ʖ ͡°)
Impressive work! You make it sound so easy haha! We just built a sign with LEDs, wasn't that simple and we kept it very simple!
Ah Lochmaster! I designed a modular synth with stripboard with v3 of that software many years ago. Super cool software. It even lets you put resistors on the backside, and at odd angles, etc.. Massively useful.
The site is probably still online somewhere. The ASM-1-SB edition. Good times!
That was a great project. Well done!
I love you videos , they are very professional , keep up the good work !!!
I'd love to see a similar project with each vertical line linked to a specific audio frequency band, maybe with RGB LED for an even cooler look :o
This would be a good project for using an LM3915 since otherwise you'd have to replicate this whole circuit for each frequency band. But, essentially, you'd just have the signal fed into a parallel array of band-pass filters, then fed into a copy of this circuit (or an LM3915) to drive each column.
That would turn out more like what we used to call a "3 Channel Colour Organ" that were very popular kits back in the early 70's and life was groovy. :)
I still have one of mine that is operational. Typically the circuit sent the speaker level audio to 3 simple filters to get low, mid and high frequencies. Separate sensitivity adjustments for each channel. Those drove some circuitry that ended up at 3 triacs, modifying the AC that powered 3 banks of AC lighting. Using 3 flood lights was good for lighting up a family room wall or taking to parties or using out side at Christmas time in the front yard. Blue for low freq. / Red for mids and Yellow for highs. No ICs; all discrete components. We had to be careful because half of the circuit was handling full line AC voltage.
@@AKADriver I thought this video possibly would use an LM3915. I can't believe that part number came to me like nothing, though I haven't seen one in over 30 years. I had a bunch of them. My recollction is the 3915 was linear response and the 3914 was logarithmic, or the other way around. Plus I believe there is (was) an LM3916. Someone suggested slowing down the response which is a very good idea. If it's possible easily, putting in some peak hold would be good too. But at any rate when it came out, the series of chips opened up a lot of projects. I used them with 10 element LEDs in an IC package. Great for chassis mount meter projects, not for projection.
Dear greatscott you are the best, electronic youtuber
You make it sound like it's the easiest thing to do.
it actually is very simple.
@@amaanqureshi1286 If you have some ee engineering experience you superiority complex gatekeeper, most people don't even for somthing like this, when you started out, you couldn't do this, stop being cocky and telling how it is so easy to everyone who has an opinion about it.
@@analogaudiorules1724 No it is very easy since it require minimal soldering skills. Just look at the circuit in the video, get the parts, and connect them. It isn't hard. I did things like this when I was 12 years old and hand zero experience or knowledge.
well, that's a great beginners project! thank you very much Scott!
Really interesting video. My compliments Scott!
You are a force of nature!
You make it look easy! last time I tried doing a vu-meter I didn't sleep in 3 days
i was going to build the same thing with a lm3914, so this video is verry helpfull. thanks and keep making awsome videos.
I love Great Scott's video :)
a true GreatScott again. awesome.
+emailausdrucker Thanks mate ;-)
It's very hard to doing these PCB without flexible wire lol.
It make me remind to old circuit's project which is very terrible.
Good job GreatScott! Keep doing short but awesome video!
am from colombia and your projectas are awesome
Brilliant project.
Yes!! The old intro is the best!
Long back I made a similar one with LM3914. Nice weekend project BTW!
Like always, You are Great !!!! Scott !!!
You will get a better display by adding a small capacitor to the rectified audio signal, so slow the response of the meter.
togethia great idea!
rectified audio signal?? if u rectify the audio signal all you get is a small dc voltage that doesn't work.
Nice video, greetings from Finland!
hi ! I am 14 years old and a great fan of your channel. greetings from India . keep up the good work!
I had made vu meter using transistor and IN4148 diode. Each led has saprate transistor. But it required more power as input signal. I connect it with speaker output of an amplifier and add a 10 uf capacitor in signal line. Its results was great. It gives a little delay to fall down of led light and also led lightup brightly.
Looks Awesome!! The next thing to do would be a full K band spectrum analyser with the LED sign
you're a good youtuber. everithing is explanated very well
Thank you for sharing , you creative as usual
Very nice! Great vid!
THIS IS FREAKING AWESOME!!!!!
Great project!
As always you are awesome!
Cool project, Bro
i love u great scott iam a kid and i have been trying out your projects
Absolutely awesome! Love it
Excellent project
Love your videos! I would really appreciate a more in depth look at how it works however! Like how you did the math to figure out all the dffirent resistors, mosfets, etc that you would need.
this project is too good
Next level VU meter ;)
Excellent video! I love your multimeter and scope too. Very nice.
I subbed a long time ago. Good videos.
Super sweet dude ! See if you could slap in a multi color LED disco ball that can be controlled with bluetooth to your future projects that'd be really neat as well.
Lovely work
Awesome video, love it!
Awesome project!! Thanks!
everything is amazing from you
This is just what I was looking for :)
Interesting! Great work mate :)
You are an electronics god...love from india...
Nice tutorial again..
Great!!!Scott!!!!
thanks man you have save on a summer shool electronic project
i like your post im electronic tech for 40 years now but I would like to do it again as a hobby thanks...
I have built a VU meter a while ago but I used an arduino and made 3 led bars for high mid and low frequencies.
This is awesome.
great video!!!
awesome project :-) !!!
Thank you very very much for your videos! stay creative! :)
Can you make it stereo by omitting the resistors following the input jack and wiring L and R to separate circuits ?
Thank you for this video
Very awesome! Thanks :)
+GreatScott! Thanks for answering. I'll try it when I get it.
Awesome my very good friend.
Wow, this. is. awesome! :D
Simple, but awesome
very nice video
Do that with color changing LEDs? Make a screen basically.
nice video.. I'm thinking I might take a crack at building my own version of it ☺
it looks great :D
you are a beast! 👍👍👍
Very cool project !!!!
But how we can make each row of LED's react with different level of sounds for making an equalizer ???
veri veri good!!
It's so bananas !
Great video! Im still waiting for the LED Cube VU Meter Color Organ combo.
You are a genius :)
Nice build! I've had another idea and was wondering if it was possible to hook up two separated, straight lines of LEDs to an audio jack and have the left and right "speaker" completely separated? For example: If the stereo audio file only uses the right speaker, the volume should only be "flashing" on the right LED-Strip. If it's only the left one, only the left strip should show something. In computer games, it could display the direction where sounds are coming from for example.
thanks for making this vid:) my comment was used!!
you are the best
u r amazing....bro
Great scott..do the n chanel mosfets have any alternatives ...please if you can help
...
Nice Brother
Thank for this I’m going to get all the parts ordered and make one myself but with my gaming name tag instead
As an industrial Q-solderer, I'm having a bit of pain watching you cutting component legs AFTER applying the solder.
I know this is how a hobbyist gets the job done, I'm no stranger to it either, at least on prototype boards.
Well anywho, great stuff, I like your projects and you've been a great inspiration for making projects in my home :)
Keep up the good, no great, work :)
Maybe you should try wire wrap, it's easy and practical to use when it comes to prototypes. Cool video, nice job!
For version 2.0, get a bunch of capacitors/inductors to make resonant tank circuits and several of those chips to have crude but appealing spectrum analyzer!!!
Probably the simplest way to do that is to use some LPF filters for the first couple letters and HPF filters for the last couple.
+Power Max That's actually a pretty neat idea!
please do a video on just how to make the led sign and power it by battery or mains if you cant with a battery
Great video! I was curious if you would be able to share the schematic file for this setup. I would love to try this circuit design for myself if possible
Great Video as always
i see that for the LEDs you used a stripbored , and for the VU meter circuit you used a perfbored, when do you suggest choosing a stripbored over a perfbored
or vice verca?
wau! nice job
Is it better if make all resistor for voltage divider in one line for inverting line op-amp?
I mean in series
Is it possible to create a lossless pass-through by adding a second audio jack and splitting the input?
Does the audio signal feeding IC1b through IC2d come after the pot (eg pin 3 IC1a) or directly from the audio source?
