In this Instructable I describe the design, construction and programming of a LED matrix lamp. The design resembles an ordinary lamp, but the interior has been replaced by a matrix of ws2812 LEDs. The control is done by means of a Raspberry Pi, so that the whole can be programmed according to your own wishes.
The lamp is about 12 inch (30 cm) high with a diameter of 4 inch (10 cm). The outside mainly consists of a glass cylinder.
With more than 40 steps it has become quite a comprehensive Instructable. It starts with the design of the lamp. This covers both the 3D design in Fusion 360, and the electrical part. Extra attention is given to the power consumption of the LEDs. For example, a special board has been designed for power distribution.
