I wanted to try and recreate the flame effect inside a lamp. It works pretty well, 299 LEDs (it would have been 300 but one got lost along the way…).

There are 5 meters of LEDs in the project! All compressed into a 25cm tall cylinder to fit inside the lamp.

The flame effect is based on the old school computer game method - see here for a good description: https://fabiensanglard.net/doom_fire_psx/

I’m using the same driver circuit that I used for my Christmas lights project - https://youtu.be/Ueim2Ko8VWo but any level shifter chip would do the job.

There’s a bit of 3D printing involved in creating the support structure for the LEDs - I used Fusion 360 for the design of this.

All in all, a fun project - works pretty well and gives a good effect.
