<p>Video painted top with frame: <a href="https://youtu.be/gsi5uamnZHs">https://youtu.be/gsi5uamnZHs</a></p> <p>This is made from scratch but inspired by TeachingTech design. This is still work in progress.</p> <p>Mine incorporates 2×18650 cells in parallel to feed 47 WS2812B LEDs.</p> <p>The size is 225×225mm, the LED area is 222×201mm, the logo area is 212×191mm.</p> <p>On the rear there are 2 keyholes 162mm apart.</p> <p>There is ample room for wire spaghetti inside.</p> <p>I've used ESP-01 with WLED software.</p> <h3> BOM:</h3> <ul> <li>Soldering iron</li> <li>Common sense</li> </ul> <ul> <li>80cm WS2812B led strip</li> <li>134N3P Power bank module</li> <li>2 × 18650 cells</li> <li>ESP-01</li> <li>10×15 SPST switch KCD11</li> <li>AMS1117 small LDO breakout</li> <li><p>piece of paper as backing or print a thin sheet of plastic Magnets</p> <p>You can either use:</p> </li> <li><p>4 6×1mm mangets for the top part and 4 6×2mm magnets for the bottom part. or</p> </li> <li><p>use a screw in the base instead of magnets (M3x18mm max with 6x2mm head, DIN 7985 / ISO 7045, DIN 965 / ISO 7046, DIN 84 will work).</p> <h3>Wiring:</h3> <p>The wiring is not too complicated.</p> <p>First, flash the WLED onto ESP01. Desolder the pins from AMS1117 and ESP01.</p> <p>Solder a bridge or a resistor (any value above 1k and below 1M) to the ESP8266, from CH_PD to 3V3 to permanently enable the chip.</p> <p>The outermost pins of the USB A output are +5V and GND.</p> <p>Connect the 2 18650 in parallel, and lastly connect them to B+ and B- of 134N3P.</p> <h3>Finishing:</h3> <p>I suggest to spray paint the top to minimize the translucent look.</p> <h3>Updates:</h3> </li> <li><p>Added a small lip to support the frame and prevent light bleeding through</p> </li> <li>Added a hole for whole lenght to mount feet</li> <li>Added clips and a channel for led strip (not tested if it fits)</li> <li>Added preview video</li> <li>Added wiring</li> </ul> Category: Decor
