TheTurtle Posted November 5, 2017 Report Share Posted November 5, 2017 I needed something to go over the expresso bar in the house. Saw something similar to this on the internet and decided to drag out the raspberry pi and some LEDs and make one for myself. I used PHP to grab the current metar every 15 minutes and updates the LED colors via Python. Used LED string individually addressable RGB lights. its about 30x20 inches. I used a digital sectional of LA and added an inset of the Bay area since I fly up to WVI pretty often. The code turned out to be the easy part. Glueing and splicing all those dang LEDs was why it sat on the living room floor for a month. Finally pinched myself in the ass and finished it up today. it shows green/blue/purple/red for the flight conditions. 19 Quote Link to comment Share on other sites More sharing options...

Yetti Posted November 5, 2017 Report Share Posted November 5, 2017 Neat work. You could also do the same with Node-red. If you don't want to code... 2 Quote Link to comment Share on other sites More sharing options...

Schematics is plug the green wire from the LEDs to GPIO pin 18 on the R Pi. I used a diode between power and the LED power as well. Cant remember why but I saw it one of the docs. I run a cron every 15 minutes on the pi to run the PHP script and update the colors. 2 Quote Link to comment Share on other sites More sharing options...
