I went to visit my cousin the other
day and he had a NanoLeaf creation on his wall that I really
admired. Being the DIYer that I am (and the cheapskate) I
decided to try and build something along the same lines. In
looking around on the Internet for inspiration, I came upon
this project on Instructables.com:
which was almost exactly what I was looking for. I wanted
something smaller than an actual NanoLeaf and this fit the
bill nicely. I used the STL files provided in the
instructable for the triangle bases, sides and control box
but created a new design for 3D printing the diffusers. In
other words, I 3D printed the diffusers using a semi
transparent filament instead of using translucent acrylic as
used in the Instructable. I also decided that I wanted to
have a triangular overall look which would require 15
triangles in total. It took around 75 hours of printing time
for the whole project. Here is a picture of the finished
TriLight device hung on my wall. The black box in the lower
right contains the electronics.
Each triangle contains a strip of 12 NeoPixels for a project
total of 180 NeoPixels which would need to be controlled. I
did not use the controller or the software described in the
article. Instead I used an ESP32 micro controller I had on
hand and custom software I had written for a previous
project. Of course the software had to be enhanced to take
advantage of lighting patterns that presented themselves due
to the triangular nature of the project. In total there are
about 40 lighting patterns that can be selected to run via a
web page and an auto mode that picks the
patterns, speed and brightness randomly. The auto
mode selects a new pattern every 30 seconds and turns off
the display completely after 15 minutes.
You can control the TriLight from any device that has a web
browser. Here is a portion of the web page used for control.
Besides pattern selection you can also control the color,
saturation, speed and brightness of many of the
patterns. If the Static pattern is selected the TriLight can
be used as a wall light of any color you choose.
The video below shows the completed
TriLight project in operation running in auto
mode. Note, because of the randomness built into the auto
mode no auto mode lighting sequences will
ever be exactly the same and many will be very surprising.
NOTE: my camera had a rough time making this video due
to the highly dynamic nature of the lighting of the piece.
Enjoy the show !
The STL files for the 3D printed
parts for this project are available here. The
code for the ESP32 is available here. The code
implements the Arduino over the air (OTA) update mechanism
so the TriLight doesn't need to be directly plugged into a
computer to update the software. This means it can stay on
the wall while being updated which is a good thing for the
somewhat fragile TriLight device.
