as promised here is the video explaining how I soldered my LED’s to create the display in my worldmap clock project.
As stated in the video, the module used is Ws2818B which are individual RGB leds individually controllable .
I bought them by 100 on Banggood for about 15€
I found a lot of useful tips on how to power it and use it properly on Adafruit’s website (which also the provider of the library to control it) Adafruit Uberguide for Neopixel
Inspired by some wordmaps made with nails found online, I decided to build my own with a little modification : it’s also a clock and of course a connected clock … I know what you are about to say, yet another connected clock ! And well … it’s true (first project, second project). But this one will be pretty !
The “background” was made using painted 8mm thick MDF and the frame was made using fir wood.
LEDs are WS2818 which can be individually addressed in order to have results like this ! In this project there are 82 leds that needed to soldered (6 points per LED). It’s a lot of word, I’ll soon post a video explaining how I did it.
I will add more behind the “background” to light the wall on which it will be hanging. And I still have to work on the Wifi connection using ESP8266 module and Arduino.
