put most of the rest of my lights up this weekend. Lost 5 or 6 strands since last time. need to find the bad bulbs and get them back in service. Video is from my phone, hard to hear audio (maybe youtube won't take it down then)
This is probably 6,000 lights. my yard is just too big, need way more lights. I haven't fired up the Pi in the workshop, it will run as networked client but need more lights first

For those with a Pi 3 B, how much faster would you say it is compared to a Pi 2? I worked on a solution for PWM on a Pi 2; worked but it just wasn't fast enough at detecting the zero-cross.
The Pi 3 might be fast enough to make it work properly.
for what it's worth, it's written in C, as I was looking at making the zero-cross run as a daemon that could provide notification, then other code could handle duty cycle for PWM from there
Cheers!

finally getting my lightshow back up. Same case as before, but I'll have 16 channels. My plans next are to mount an LCD monitor in the door of the case so I can have touchscreen control over the Pi. Still have some cleanup to do with wires and one last SSR to connect. If plugged into 2 circuits, I could run about 20 amps total.

Been gone for a while, busy busy. Hope everybody is getting their shows setup. I have about 3/4 of my lights up but it's snowing like crazy.
I'll be setting up my leaping arches this year. also built 3 small trees with tomato cages. will try to get pics soon

I've been invited to the area Tech Center (at the high school) and will be bringing a lightshow PI setup (along with some high voltage stuff)
hope to get some of the kids interested in the Pi, programming and hardware.
I put my Halloween Helmet back together for today as it's fairly portable. Should be fun. Too bad the school year is almost over. Any of them that have any interest would have to wait until the fall to work on it, if they have to do it in school

scored 20 more Opto22 10amp SSRs for $2.15 each ;-)

I've been tapped to play DJ again (DJ Raspberry?) for an elementary school party. Local music store cut me a great deal on a used 10' light truss so I snagged it. Can't have the lights tipping over. ;-)
This is a test run in my shop from last weekend. Using Audio-In mode. Laptop playing music, connected to mixer, CR/phone out goes to Pi for audio-in, then of course main outs to speakers. This time though, I have to be a bit careful, at 600 watts my ears are still ringing ;-)
Lower left is media cart with laptop and case with Raspberry and relays.
Same problem with this setup as at Christmas, not enough lights!
