500 LED-Pixel RGB-Brick
Amazing project, congrats!I was able to install the NETIO with your JSON file, it works fine!You stated above that you not want to upload your code yet, but is there an estimated release date? Electronics and woodworking is no problem for me, but i will never figure out how to design a Teensy sketch.So before i start this beauty I will wait for your Teensy code,Thanks for your inspiration!Regards Frank
1. Only the ESP works with 3.3V. The LEDs and the Teensy works with 5V. You don't need a voltage regulator when you use a Teensy 3.2, because its regulator on board can handle the max current for the ESP.2. I have added this buzzer only to verify the wifi connection. It beeps only the first time when the brick has power and there is a command from the iPhone. Other sound effects can be played by using the Teensy audio board.3. V-Reg is the voltage regulator mentioned in the first answer. Cause the ESP can handle only 2.6-3.6V you have to regulate the power from 5V to 3.3V.4. The switch resets the wifi module (ESP). It does not turn the wifi on or off, it was just to test the wifi communication and it is not necessary.5. You can use any controller of your choice, but the Teensy uses the same Arduino IDE as an Arduino or an ESP. You only need to update the IDE to (I think) 1.6.5 or higher. Follow these instructions to get the boards-manager in your IDE: https://github.com/esp8266/Arduino6. Of course this is possible! The Teensy audio board has direct pinout for a mic, but even if you don't use the audio board you can attach a mic to your microcontroller: https://learn.adafruit.com/adafruit-microphone-am...
I have the same idea and will make one to display all minecraft brick!! - JeffreyC45

Dear Moekoe,This is awesome and me and my friend want to built it, but can you please give detailed info how to connect all the leds and the schematic from the breadboard please? I not understand the drawing you make with all the numbers, but I want this baby, love it! Regards John - shadowfox64
I get a couple of questions on your breadboard picture:* Voltage is 5V, all components works under 5V ?* Why the buzzer is plugged on the wifi module (and not directly bound to the tensy)* What is the component V-REG ?* The switch in the middle is gonna switch off/on only the wifi ?* Why using a Tensy (looks like it required special IDE) ? Is there a chance to work with any other arduino ?* Last but not least: should it be possible to catch sound through a mic (I though at equalizer capabilities) ?RegardsChristophe
You're welcome!Feel free to ask if there are any questions. I want to see some pictures if your brick is ready! :)
Many thanksI know what to do this winter ;-)I'll keep you in touch if we success or if we need some additional help but it sounds pretty clear.Christophe

That looks very nice! I love the blurred look. :) Why do you use both the white and black acrylic?And of course the question: Why do you don't write an instructable about it?
Thank you! Good luck to you.All the rows of the strips are welded together and only the first pixel of each matrix are starting with a simple 3-pin JST connector. (In the picture you can see one male connector which comes from the end of the side matrix but it is unused. Only the females are going to the controller board.) The connectors are getting into the cube by small holes in the edges.I'm getting mostly all of my parts from www.exp-tech.de, like the Teensy 3.2: http://www.exp-tech.de/teensy-3-2. But these are shops in germany. I don't know where to buy electronics in other countries. For the LEDs you can refer to AliExpress. A good reseller is Ray Wu: https://de.aliexpress.com/store/product/BLACK-PCB-5m-DC5V-WS2812B-led-pixel-srip-IP68-30pcs-WS2812B-M-with-30pixels-reverse-protection/701799_926778326.html?spm=2114.8147860.0.0.mxgmWE. Hope this will help you a bit.
Amazing ! This is really nice, congrats !I thing I'll try it with my son.Wood working and coding is not a pb for me but i'm a newbie for the electronic part.Is it possible to get some additional pictures on LEDs connection (Do you use connector clip, welding, ...)finally if you could provide some ebay / amazon link for electronics parts (arduino, buz, ...) I'm able to do some search on internet but as it's my first try I'm afraid to buy a lot of wrong items before success :(ThxChristophe
This is pretty insane! WOW :O

And a video of it with the housing: This is it running the same animation as before, just inside the laser cut acrylic housing.I'm not super happy about how much the light bleeds, but it still looks good :)The housing is 3mm black acrylic laser cut to go around the pixels, then a 3mm white acrylic over the top.The capacitors on the panels stick out a bit, so there was a gap between the PCB and the black acrylic, which caused massive bleeding. To fix it, I laser cut some foam in the same pattern as the black acrylic and stuck that on.
Thanks!I don't want to upload my whole code yet. But I just added another step with some pixel assignments. The total cost are about 350-400 Euro, but as I told in a comment before you can save a lot of money (maybe the half) by ordering the parts at AliExpress for example.Have a look at the new 5th step. I was using the simplest solution in coding, but therefore I have to convert the snakehead to the correct position at the specified cases. The body of the snake is just following the head. Polar coordinates would be very nice but implementing them on the brick at this time is too difficult for me.No, I'm just using the jack on the bottom of the cube. The music visualizer is based on the fast fourier transform. I have not had enough time for testing the audio connection more then just with this simple visualizer.I have though about this while building my 10x10 coffeetable, but for the brick it will be to expensive. The 500 sensors would break my budget for this project.
No, thank you!Just added the 5th step. Hope this helps.
