Yesterday,
|
|
|
|
|
one of $CHILD's friends from dance drove up so I could help her bling out her truck.
|
|
|
|
|
We used WS2811 LED strings with adhesive backing.
|
|
|
|
|
I flashed a Seeeduino Xiao with CircuitPython,
|
|
|
|
|
set up an example program,
|
|
|
|
|
and let the two of them go nuts writing light animations.
|
|
|
|
|
|
|
|
|
|
Then we went out and stuck the stuff to the truck,
|
|
|
|
|
reinforcing it with zip ties for when the adhesive inevitably loses its grip.
|
|
|
|
|
The moms braided some wire into 3-connector cables,
|
|
|
|
|
the friend soldered a bunch of stuff together,
|
|
|
|
|
and we plugged it in.
|
|
|
|
|
It friggin' worked!

The really cool part, at least for me,
|
|
|
|
|
is that now she can hang out with her laptop in the cabin,
|
|
|
|
|
reprogramming her ground effects to do whatever she wants.
|
|
|
|
|
Like, with a Chromebook, even.
|
|
|
|
|
Or a mobile phone.
|
|
|
|
|
CircuitPython is crazy inefficient,
|
|
|
|
|
but it made this stuff so easy.
|
|
|
|
|
|
|
|
|
|
Phase 2 is going to be getting a Bluetooth Adafruit chip,
|
|
|
|
|
setting it up to pair to their phones,
|
|
|
|
|
and then letting them control the color and pattern with a cell phone app.
|
|
|
|
|
Then we'll be able to relocate the chip under the hood by the 12V battery,
|
|
|
|
|
and route wires in a better way.
