I hired an editor for the first time. What are your thoughts on this new style?
I would say that the music does not need to be throughout the whole video. Especially during direct dialogue. It’s fine during transitions or B-roll or build footage, but is distracting when it’s a static shot of you talking.
Loved your video last year, I can't wait to see what this looks like with over 25,000 pixels!
I love project from last year im actually about half way done atm just a few more pieces to print. It gave me a great refresher on things i haven't messed with sence middle school before computer programming took over. But my absolute favorite thing is during building this project a few family kids and there friends got excited and actually sat down and made one of the sections together. None have ever soldered or done anything and their board works just as good as mine and they only had to cut and replace 3 leds so at a cost of 5.92 a strip it cost me basically nothing to get 3 new kids excited about what they can build with a little research and a idea. So thank you again for this project!!! you made me the favorite uncle for at least a day :)
Don't forget with larger LED strips/panels to do power injections and that if you're driving a lot of LEDs, don't power them directly through the controller/mcu. For BIG LED projects, a wall brick may not cut it, like if your LEDs are drawing 10A, a 10A power brick is going to get awful hot, so I'd just go for a switching power supply.
for more panels, use a Hilbert curve to lay them out. it can then be computed instead of using memory for the location of each panel
Great tip! I hadn’t thought of that
Great video. I look forward to the next one. I think the editing looks good.
::Warning Info Dump::
For anyone interested in other ways to skin a cat, wled is great software and easy to install on esp32 or esp8266 controllers. It handles 2d matrixes now and connects over wifi/ethernet. Wled understands Artnet. For larger projects like this wall, xLights can push syncronized images/videos/patterns with or without music (not through wled but synced). Xlights runs on a pc usually and is the designer and server but if you don't want the pc to run 24/7 there is Falcon Player which can run on a RaspberryPi to keep the show alive. Falcon also makes boards designed to control thousands of leds over a network and direct connect. All of this is from the Christmas Light community and is fairly robust. Not cheap necessarily. If you want more robust esp32s with ethernet optional i would check out QuinLed boards. Lots of good info about leds on his site too. Lastly if just want cool patterns and syning multiple wled device LedFX will use sync the LEDs to music via network from 1 point (pc mic for example). Lastly you hook all of this into Google/Alexa/Home Assistant to integrate schedule and sensor inputs or buttons to trigger scenes or shows on the Wall. Turns off when you leave. Dimms when its dark. Changes to blue when it rains. Create a giant timer when you are late for an appointment. Etc anyway i hope that helps someone and isn't too much.
I made one it was a really good project!
Amazing!!
Great idea to go with those cheap 16x16 panels but I hope you go with the esp32 for your next project. One esp32 can output to 16 panels parallel at 120 fps. Instead a hundred esp8266 you need just 8 esp32. And the best part is that the esp32 is still supported by Espressif esp-idf. Not only will you save money and simplify your build but your microcontrollers will also receive software updates.
I am using an esp32 on a custom PCB. Unfortunately the typical dev kit is not compatible with LMCSHD because of the way the esp32 handles USB serial data. It’s a weird quirk I’ve had to fight with since my first LED wall
Oh. You're still transmitting the data over the USB. You'll be limited by the bandwidth. Why not use the ethernet and the ArtNet protocol? Is it too much trouble to add that functionality to the LMCSHD?
It will probably be easier to switch to a better software that already supports artnet. Definitely the direction I want to go in the future but I’m a hardware engineer so my software skills are holding me back for now
Maybe you could use some other people's code and just focus on the build itself. Here is a video of friend of mine running 48 panels on one esp32. I have only done 14 myself.
You can use his libraries and examples or even ask him for help.
I also dabble with these panels and have made some projects with them. My channel might be well worth checking out.
I'm the opposite of you. I love programming but struggle with physical designs.
Have you heard of WLED? Its open source and supports matrixes. The programming of multiple panels would not be a problem with that.
I’ve used WLED and it has cool effects but this software supports screen capture which has way more applications. I actually have a tutorial on this channel for some cheap WLED lamps that I still use every day
You have got Good Kid in the background!
Was this project related to/inspired by their live rig and their LED panels?
I just saw them live and they only had stage lights and a banner with their album art. No LED wall unfortunately but it was a very small venue
@@TheTechRandom th-cam.com/video/9shkVEy0fI0/w-d-xo.html I took this video at their show in SF. Custom LED Guitar Cabinets that have some sort of panel in them.
I would love to see that next project. But please make the 'how-to' steps more clear.
My only complaint is the line you can see every 16 pixels. Must be a slightly different width seem.
Hey my friend, I had a sorta personal question. About how much do you make a month with 7k subscribers - from just TH-cam Adsense. I have a new channel as you can see and was just curious. Thanks buddy. BTW Great video.
I peaked at $200 but I’m sitting at $50 a month right now since I don’t post all that often. I’m a full time electrical engineer so I don’t rely on TH-cam for money.
missing link to github page :/
Added! Thanks for the catch
