Now added a video with the first five light effects based on the FastLED lib.

Now I have added the 193th LED at the top of the tree. A WS2812 8mm LED from Adafruit, which I have ordered a long time ago for testing purpose. After some try and error I figured out, that this LED needs RGB byte order instead of GRB like the WS2812 at the LED rings. So I decided to use a different GPIO pin of the Teensy to drive this single LED.
Assembly

I have just assembled the acrylic tree with the 7 LED rings. I am also planning to add one special LED at the top of the tree. Using a Teensy 3.5 board and a 74HCT745 level shifter, next step will be the programming of different lightning effects. Should be finished before Christmas...

Hello,... thank you for sharing this project.

I've downloaded the file but there is no RingBuffer.h file.

Can you help by uploading it here ?

Thank you and Merry Xmas.

why do you need the 8mm WS2812 LED when you already have the rings

what is the 74HCT245 used for

and will a teensy 2.0 work?

Are you sure? yes | no

- The rings from amazon have less LEDs and maybe different diameters, so you need a different structure to hold them.

- because it looks nice ;-)

- Teensy is 3.3V, but WS2812 is 5V, so the 245 works as a level shifter. Hundreds of other solutions out there.

- yes, a Teens 2.0 will work, even a Arduino Uno will work, just used the Teensy because I had one.

Are you sure? yes | no

Do you have a number how much current (mA/A) this is using?

Are you sure? yes | no

makeTVee wrote 12/09/2016 at 20:24

It depends, 300mA for my first testing animation. I am using the FastLED lib, so it's also possible to limit the maximum current via software.

Are you sure? yes | no
