The column is modelled after the LEGO Castle Items Torch without the windswept flame, and my lampshade is modelled after the 4589 LEGO cone. The flame lampshade was made by Gianfranco Crevani and must be printed at 116% scale in order to fit. Here's Gianfranco's project page for the flame: <br> <a rel="nofollow" href="https://www.thingiverse.com/thing:1366940">https://www.thingiverse.com/thing:1366940</a> <br> The Lamp is powered by a NodeMCU v1.0, and is running the McLighting project in the video. This lighting project for the ESP8266 is written by Tobias Blum, and has many interesting features.

M3 countersunk machine screws could also be used here, but the holes in the base may require tapping.</li> <li>The use of JST or other wire-to-wire connector is recommended to make removal of the internal bracket quick and easy</li> <li>Hot-melt glue works well to secure the Lamp column to the lamp base, and also the LED ring to the internal bracket. </li> <li>The silicon rectifier diodes on the NodeMCU supply rails drop the input voltage to ~3.6V, which is within the range allowed (it's the maximum). This setup allows the device to control the 5V WS2812's directly. DO NOT use schottky diodes here- you want at least 0.7V drop per diode.</li> </ul> <br>
