I have configured two Pis for networking, one as server and one as client in the overrides.cfg file. What now? Do I just start_music_and_lights on both machines or is there something else I need to do? Not sure how to get things going on both machines. Not even sure if my config is set up correctly. Just wanted to see if I can get the two Pis talking together with lightshowpi. Thanks!

I'm experimenting with a crude form of sequencing I thought might work with LightShow Pi, but so far, no luck. I think it might be because I don't understand well the custom_channel_frequencies option.

My thinking is that I could set up some high frequency channels that are above the audible range to be used for manual sequencing. Using audio editing software, I'm adding a 22000Hz tone where I want the lights to come on. I changed the overrides.cfg file with the following line just to see if I could get channel 8 to come on and off at my command:

custom_channel_frequencies = 0,833,1666,2499,3332,4165,4998,5831,6664,7497,8330,9163,10829,11662,12495,13328,15000,23000

It didn't work. I even cleaned out all frequencies above 15000Hz before I put in my 22000Hz tones. Is this an idea worth pursuing? I'm not sure if I'm setting up the custom_channel_frequencies right, or if it is even possible to do what I have in mind here. I'd ultimately like to make 3 channels that I can control with 3 different inaudible tones. Any suggestions?

Can someone recommend a good resource on learning to use Git?

I would like the web.py to launch on startup. I found this discussion on stack exchange about startup scripts. https://raspberrypi.stackexchange.com/questions/8734/execute-script-on-start-up

Please help me connect the dots. Can I just add @start_microweb to the autostart file? Thanks!

I'm brand new to this and just wanted to say hello. I'm loving your LightShow Pi project. Last year, I ordered a solid state relay board during the Christmas season, but it took so long to arrive and I got busy with other things, I put it away. This week I got it back out, along with my Pi computer that I know very little about to see if I could make it work. I quickly learned I need female end cables, but my Canakit only came with males, so I borrowed some cabling from an old computer and cobbled something together.

Thanks to LightShow Pi, I now can make blinky lights! Here is a link to my blog that shows what I've done so far. http://billgx.com/2017/10/lightshow-project/

Now to figure out the music part.

My students didn't realize it, but the computer networks and the OSI model are like onions.

Recently we discussed data encapsulation in my intro to computer networks class. My students didn't know this was covered on an episode of Spongebob.

I'm surprised this doesn't include Win 95. That was a major advance. And don't make fun of Win 98. I used that Windows OS longer than any of the the others, I think.
