<p>LED-PingPong Ball Video Wall</p> <p>inspired by bitluni's version</p> <p>-&gt;<a href="https://www.youtube.com/watch?v=ikhZ34WgObc&amp;list=WL&amp;index=27&amp;t=0s">https://www.youtube.com/watch?v=ikhZ34WgObc&amp;list=WL&amp;index=27&amp;t=0s</a></p> <p>Thanks Bitluni!</p> <p>-&gt; <a href="https://youtube.com/bitlunislab">https://youtube.com/bitlunislab</a></p> <p>-&gt; <a href="https://twitter.com/bitluni">https://twitter.com/bitluni</a></p> <p>Using WS2811 LED chains</p> <p>Update: I also tested Spectre's new Software to control LED Matrix display from PC, Android or Raspberry -&gt;</p> <blockquote> <p>I discreetly made public the repo of LEDs master Go test it, there are versions for all platforms. I know a lot of people really want to be able to control LED masks and costumes, wirelessly. feel free to give me lots of feedback<a href="https://t.co/duSrRs1rTl">https://t.co/duSrRs1rTl</a><a href="https://twitter.com/hashtag/LEDs?src=hash&amp;ref_src=twsrc%5Etfw">#LEDs</a> <a href="https://twitter.com/hashtag/lua?src=hash&amp;ref_src=twsrc%5Etfw">#lua</a> <a href="https://twitter.com/hashtag/love2d?src=hash&amp;ref_src=twsrc%5Etfw">#love2d</a> <a href="https://twitter.com/hashtag/dmx?src=hash&amp;ref_src=twsrc%5Etfw">#dmx</a> <a href="https://t.co/7pO2k65nW8">pic.twitter.com/7pO2k65nW8</a></p> <p>— Spectre (@spectrenoir06) <a href="https://twitter.com/spectrenoir06/status/1281678379994013697?ref_src=twsrc%5Etfw">July 10, 2020</a></p> </blockquote> <p>Code for the ESP32: <a href="https://github.com/spectrenoir06/OctoWifi-LEDs-Controller">https://github.com/spectrenoir06/OctoWifi-LEDs-Controller</a></p> <p>Code for Win / Android / Debian: <a href="https://github.com/spectrenoir06/LED_master/releases/tag/V0.4">https://github.com/spectrenoir06/LED_master/releases/tag/V0.4</a></p> <p>I added screenshots with the parameter changed for this LED wall to the project</p> <p>Printable version instead of metal hole pinching and welding.</p> <p>All parts printable without supports, size of each part smaller than 20 x 20cm</p> <p>4x4 table tennis ball pixels per print part, so the final size is modular.</p> <p>In this assembly 33 x 18 pixels are used for a roughly 16:9 screen in 1,5m x 0,75m</p> <p>Framework with caprails for better stability.</p> <p>Integrated ESP32 with Webcam in the middle for direct stream or any other arduino controller</p> <p>I included also the Step-Files of each part for easier modification and also a Step-Assembly with all electronic parts and an according PDF-drawing</p> <p>I printed the parts in PLA with 0,3mm height for shorter print time.</p> <p>Roughly 2-3h print time per part</p> <p>I used following parts in this build:</p> <p>1x Camera for ESP32 with long cable: <a href="https://www.banggood.com/LILYGO-TTGO-Camera-Module-OV2640-2-Megapixel-Adapter-Support-YUV-RGB-JPEG-For-T-Camera-Plus-ESP32-DOWDQ6-8MB-SPRAM-p-1478816.html?rmmds=myorder&amp;ID=6156886&amp;cur_warehouse=CN">https://www.banggood.com/LILYGO-TTGO-Camera-Module-OV2640-2-Megapixel-Adapter-Support-YUV-RGB-JPEG-For-T-Camera-Plus-ESP32-DOWDQ6-8MB-SPRAM-p-1478816.html?rmmds=myorder&amp;ID=6156886&amp;cur_warehouse=CN</a></p> <p>600x WS2811 LED Chains <a href="https://de.aliexpress.com/item/32444134206.html?spm=a2g0s.9042311.0.0.3da24c4dhLNruT">https://de.aliexpress.com/item/32444134206.html?spm=a2g0s.9042311.0.0.3da24c4dhLNruT</a></p> <p>600x Ping Pong Balls <a href="https://de.aliexpress.com/item/33019055387.html?spm=a2g0s.9042311.0.0.3da24c4dhLNruT">https://de.aliexpress.com/item/33019055387.html?spm=a2g0s.9042311.0.0.3da24c4dhLNruT</a></p> <p>1x 5V 40A Power Module <a href="https://de.aliexpress.com/item/33019550900.html?spm=a2g0s.9042311.0.0.3da24c4dhLNruT">https://de.aliexpress.com/item/33019550900.html?spm=a2g0s.9042311.0.0.3da24c4dhLNruT</a></p> <p>A small 5V PIR sensor and a relais to switch on the main power supply only if somebody is in front of the video wall.</p> <p>Have Fun!</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Anycubic</p> <p><strong>Printer:</strong></p> <p>All-metal Mega</p> <p><strong>Rafts:</strong></p> <p>No</p> <p><strong>Supports:</strong></p> <p>No</p> <p><strong>Resolution:</strong></p> <p>0,3mm</p> <p><strong>Infill:</strong></p> <p>10%</p> <h3>How I Designed This</h3> <p><strong>Solidworks</strong></p> Category: Electronics
