Congress is coming, 18 days to go!
The whole point of
sharing my plans yesterday
was to make sure I actually
do them. Easiest on the list is to set up the UDP controlled blinkenlights
panel. I am going to attach this to my bag or something, there must be cool
blinkenlights everywhere I go.
The panel is a 8x8 Addressable RGB pixel array made from the super popular
WS2812. Control is a NodeMCU board running micropython, the NodeMCU board is a
ESP8266 broken out in a sensible way, it means I can get this cool little
project on the network.
I have some pieces of clear acrylic and foam sandwiched together to diffuse the
light, all held everything together with some bolts. Here is the small test
script I have put together so far:
import machine
import neopixel
import time
pin = machine.Pin(14, machine.Pin.OUT)
np = neopixel.NeoPixel(pin, 64)
skull = [
0,0,1,1,1,1,1,0,
0,1,1,1,1,1,1,1,
1,0,0,1,0,0,1,1,
1,0,0,1,0,0,1,1,
0,1,1,0,1,1,1,0,
0,0,0,1,1,1,0,0,
0,0,0,1,0,1,0,0,
0,0,0,0,0,0,0,0,]
while True:
colour = uos.urandom(3)
for x in range(len(skull)):
if skull[x]:
np[x] = colour
np.write()
time.sleep(1)
I am going to accept any 8x8 RGB frame (any 192 byte packet) that is sent and
take any other shorter packet and use it to set the colour on the skull. I will
include a timeout to change the colour so it isn't just a static panel.
If I find a load of spare time between the sofa cushions I will throw together
a web interface.
