"Saturn" mood light.

[mkstevo]

A simple mood light. Does nothing more than cycle through colours at random. I thought it looked effective though.

I had some smaller "NeoPixel" WS2812 rings left that I didn't use for my recent clock project and wondered what I could do with them. This is the result.

Code attached. There is little to the circuit. It is a PIC12F1840 and a 470R resistor in series with the data line to the NeoPixel rings. That's all. At the moment the circuit is on breadboard. Once I've figured out a base to use for this, I may make a more permanent PCB for it, using either VeroBoard or an actual PCB.

A picture may speak a thousand words, but a video must speak 10,000. Video on YouTube: https://www.youtube.com/watch?v=LbpWKwFgQE0

Nice. Cool when you make something, I think. I don't finish many projects myself.
here is a project I am doing.
a variable strobe from 49 to 52Hz??
a water pump..on it's way £6.04 but I got one but can't find it :(
here's the idea https://www.youtube.com/watch?v=qFXIhrDc6Rw
The strobe would be bright white leds and a fet to power them?
I haven't tried this code but it's a thought as to flash the leds at near the 50Hz pump...
if the pump pulses water at 50Hz. It is supposed to be variable using a 10K pot.
pulseout leds,1ms would need experimenting with.
I will be back when I got the pump and leds.
I tried the code and sorted errors and it seems to work.

#chip mega328p,16
#option Explicit
#define leds portd.7
#define potentiom portc.0
dir potentiom in
dir leds out
dim potval as byte
do
  potval=readad (potentiom)
  wait 18 ms
  wait potval 10us
  pulseout leds,1 ms
loop

Check out youtube for interesting ideas that could be done with gcb.
