Led Matrix Lamp
prusaprinters
<h4>Description</h4><p>Simple lamp to host a flexible 8x32 LED's matrix. Combined with correct hardware and software it can be controlled from self phone and get some cool effects.</p><h4>LEDs matrix</h4><p>Used a flexible 8x32 LEDs matrix. <strong>Dimensions: 317.5mm x 81mm x 2.5mm</strong></p><h4>Power supply</h4><p>There is a hole to put a 5.5mm 2.1mm female jack for power supply. I used a 5v 3Amps one, but it depends on your LEDś matrix specifications.</p><h4>Hardware/Software</h4><p>I have connected the led matrix to an ESP8266 (NodeMCU in my case) with <a href="https://kno.wled.ge/">WLED</a> on it. If ESP32 is used I would suggest to use this <a href="https://github.com/atuline/WLED">WLED </a>(Noise reactive) that support 2d matrix in a better way.</p><h4>Light diffuse</h4><p>Two things have been made to get a good diffusion. </p><ol><li>Add distance between the LEDs matrix and the diffuse screen</li><li>Add a diffuse screen</li></ol><p>This configuration worked fine for me with white PLA. I have also tested transparent PLA but I only got vertical diffusion, what is also cool, but not what I was looking for.</p><h4>3D print</h4><p>No support is needed</p><h4>Assembly instructions</h4><p>There are only 3 parts, and there are grooves in both the top and the bottom part to put the LEDs matrix and the diffuse screen. The diffuse screen helps to keep everything in place</p><p>The pieces have been designed to fit, however, I had elephant foot issues with the diffuse screen and I needed cut it to make it thinner.</p><p>Assembly steps:</p><ol><li>Screw the power supply jack to the bottom piece</li><li>Put the LEDs matrix in the top piece internal groove</li><li>Put the diffuse screen in the top piece external groove</li><li>Put the bottom piece</li><li>Connect wires (power supply, led matrix, and whatever hardware used to control the LEDs)</li><li>Power it!!!</li></ol><h4>LINKS</h4><p>https://github.com/sermelo/leds_matrix_lamp</p><h4>TODO</h4><p>Close the bottom piece. It is very convenience to have it open to connect all wires, but it will be great to have a lid to close it.</p>
