Mind blown. Have spent the entire last week trying to do this with ICs, analog circuits, ancient texts... and here it is, on my favorite µC

Meanwhile some programmers require Core i9 to flash a single LED.

With every upload... It's like you know the project I'm working on! Don't stop these quality vids on microprocessed video!!! Please! I love each one so so so much man! 🙏

This is some really nice work! I love that you work in different environments, like the converter webpage.

OMG that is just sooooo cooool (and your explanation graphics are superb)

Explanation and visualization are simply superb, can imagine how much hardwork has gone into making this.

Excellent job! The animated explanation of the tv lines and timing are the best i have ever seen. Keep doing!

Thank you for all the in depth explanation. Really interesting and really impressive

This is so clever, I really love what all of you do with these wonderful and cheap kits.

Man, you must be having the most fulfilling that one can dream of. You are my inspiration for such electronics.

Obviously your definition of "quite simple" is different from mine. That's some amazing work! The last time I did bit-banging video, I just about got a PIC micro to display two grayscale bars (and that took a week's worth of evenings to get all the sync pulses sorted out, after which I swore never to try it again)

I have been waiting for this video, I did not think you would get such great results. Well done!

Getting a lot of my favorite 3D prints spinning on my TV :) This is all very cool, its going to be the start of many fun things I think. You the man!

Now that is impressive! 2 wire display! awesome. (PS for those of you that only have component video, you can you the green grey scale channel)

Very well animated. Thanks for linking sources. A+ video!

Wow that's amazing. Thank for doing all this work - it's amazing to see what is possible! Again WOW!!!!

That's exactly what I was looking for after your last video. Thanks.

Amazing, now I can display data from my home automation on my TV. Thank you!

Just perfect. Thanks for this great presentation!

Clever! Thank you for spoiling our minds and providing chewed information.

This is certainly one of the coolest videos I've ever seen on youtube. Really didactic, and really cool!

Wow... just wow!!! 😍

Man you are amazing and a big inspiration to me. Really appreciate this videos.

Simply awesome! a great great great explanation of the CRT display science.

Wow! This is a very impressive application!

Nice explanation, and editing... Awesome work man 😁 Well done 👍

great topic, great series. thank you.

I'm impressed! Luckily I have one ESP32 module (specifically the one that comes with built-in OLED + LoRa module) so I'm definitely going to try this out!

I'm impressed !

It is a good time to be alive ;) Great video. Thanks.

This will help me with my crtelecaster project, thanks alot!

Simply amazing, dude!!! Kudos

Brilliant !!! I subscribed and liked . Thank you very much for such explanation and your time !!!!

This is so forward to my knowledge... but sure awesome stuff you're doing! :) Keep up the good work!

Very nice piece of enginering, good work!

Very very good content! I'm really amazed. Please keep up the good work. Cheers

Awesomeeeeeeeee !!! so enlightening ...thanks for sharing the knowledge

as always amazing cool videos composite video with esp32😊

Very impressive man! Keep the videos coming

Bravo, very cool! Thank you for posting

Very nice work!! You could probably use an op-amp to scale down the DAC output voltage so you can use more than 77 shades.

I remember watching this video and trying it out while literally not knowing anything. Now I kinda know a little about the esp and arduino and i actually understand how the code works (at least the simple parts)

This is impressive. Great work

Great video, nice signal animations

Unbelievable! Great job!

I really enjoy your channel.

Great video, thanks so much for the explanation!

Thank you. Nice work

You're a wizard, Harry!

Ah...the ESP32 one of my favorites❤

Really great work!

Kick ass work!!

This is so cool! Thank you!

Excellent work sir. Subscribed.

Parking monitor LCD are sold for less than €20, they are LCD with composite input. Light, low power (can be powered with 5-7V), inexpensive. Perfect as small monitor for DIY projects.

Very, very impressive!

Great video again!

amazing stuff!

Ha! Got this working on my ESP32, can't believe you can do this. I'd like to generate a teletext signal, there's a project for the raspberry pi that does it, but not seen anyone who's done it for the ESP32. It must be possible, very similar to generating composite video I guess? 4 to 6 lines instead of 625.

This is awesome!

One word: Awesome!!!

Great Work!

Great video, and to top it all nice documentation! Bitluni, I was wondering: The ESP32 CAM, would it somehow be possible to capture the video in from the ESP32 camera, digitize it and output it using your method to some old TV/LCD-screen in BW or gray scale? Have you seen any such examples?

Great explanations :) But what are the 2 resistor values for the voltage divider ?

Typo on first link, should be "composite" vs "compositve". Anyway, very nice job on the video, and the animations were totally worth it. Awesome Stuff!

very nice explaination

Hey @bitluni! Amazing projects, and thanks for sharing knowledge with us! About one year ago I had the chance to get 7 small black&white CRT intercoms systems, wondering if i can build a 2x2 CRT matrix! now, after some time, I wanted to begin, and found your CRT projects, amazing! I'd really appreciate if you have some advices about how to do it :) I'm thinking about using both DACs on the ESP32 and "multiplex the signal splits" on the monitors, do you think it's going to work? also... I think I need to split each line based on the horizontal amount of monitors (2) and stretch every part in order to fill the monitor line, then going to the next monitor... I 'm wondering if I have to draw the whole screen before going to the next one of i have to draw the lines sequentially on all monitors... also, the manual indicates that the monitor gets a CCIR input signal, do you have any suggestion about how to output that signal? Thank you, and again thank you for sharing your experiments!

Oh god, this is by far the most coolest microcontroller ideas I have ever seen. Doing this with a simple ESP32 micro is a jaw dropper... can you do the same with an AVR chip or ARM chip which has I2C? Is it possible you can do this using UART or SPI or Bit Banging? Matter of fact, you can convert the analog signal to HDMI signal using low cost common video IC chips. Either way this composite video signal from a simple microcontroller gives more control and design ideas for adding LCD to an ESP32 project.

I think classic consoles use a MUCH simpler sync pattern and don't use half line shifting, this way they achieve half-resolution non-interlaced display. And hey it works.

Hi Bitluni! Excellent job, continue that videos!!!! One question, can to use composite video to s-video cable beacuse I have that, or is need just composite video to composite video cable. Thanks advance!

Brilliant. I have no need to do this but it was interesting.

Brilliant. Made my head explode.

I have to admit, I'm more impressed by the animations you show than by the fact you generated a FBAS/CVBS signal ;) I also like using low level hardware stuff of the ESPs to generate signals. Did that on my own to control a large LED matrix that has no own controller and needs multiplexing. Works fine, however, I only show boring text on it because I'm really bad at doing animation / graphics :/ So, really nice job! Btw. You know, you have to go wireless and color, right? CNLohr did that too :)

Amazing video! Do you think this can be used into a more modern display (vga/dvi)?

Great job mate 👍 👍 👍 👍 👍

Awesome. Thank you

Gracias por compartir! Saludos

Great stuff. Getting the video timings right for interlaced isn't easy. The fact that you are rendering 3D meshes on the second core is so cool as well. ;) Something I've wanted to do for many years is to write a 3D graphics core on FPGA. I will definitely give your code a try with the ESP32 first. It's super handy for getting a display output easily. I remember seeing Charles' NTSC ESP vid for the first time. It was also very impressive.

Astounding.

You may not be able to do composite (color), but with three parallel outputs you should be able to do component video in full color and then if you want composite from that use an external modulator circuit

What tools did you use to make the animation starting at 1:59? It was so well explained. Thank you very much.

Two useful projects would be using it to convert ip camera, and also for wled, display what's going on with all the lights layed out and other stats

I just tested CompositeVideoSimple and CompositeVideo on HUZZAH32 and they work! A1 and A0 both work as composite video out. Both PAL and NTSC seems to work equally well on my 5" video monitor. Maybe you could print temperature and Hall-sensor.

You could recreate a ZX Spectrum with this or something similar, that would make a great learning tool for children. I loved the fact of th ZX that you get a blank slate kind of machine which leaves so much space for your own imagination. Could you make it with micropython for example and a way to store programs?

0:33 I have got completely the same model of Sony Trinitron (also 14 inch), which was used in the late 1990s and the early 2000s by my older sister (I am 25 and she is 41 now), but after the analogue television switch-off it remains almost unused. Our unit is stored in our garage, but unfortunately, it is actually much dirtier than that on the photo and needs thorough clenaning!

wow you're genius!

Ok that all went right over my head but hey I used to play PS2 with those composite lines

You are insane :) Awesome explanation - thanks a lot! The hardest part is to find a monitor with composite oder scart these days :D

Loved it! I enjoy your English accent... It's strong, but you're very easy to understand. There was one word that threw me though... Sounded like you said predeceased.. Was it "preceded"?

Wow, thanks for sharing :-)

Super cool! 😍😍😍

It is working flawlessly. Thanks Bitluni. Now, I'm trying to transmit at a tuned frequency in PAL without the composite output. Do you think it would be a complicated step? I'm still struggling to understand the code globality. Thanks.

nice job

nice application

So cool!

**BOOOOOOM** (mind blown)

You blew my mind again 😐

The visualizations in this are fantaaaaaaaaaaastic, what'd you use to make them? I'd really like to step up my teaching game with stuff like that.

How about use 2 dac0808 for signal and color
