Sounds good to me! Having a fully functional master board for testing would be a big help. Having one slave to plug in (even without relays) would be even better. Right now I am making do with a circuit board similar to the 3 '595 chips I added to the master for slave select and status. I can always convert this board to act as the slave if necessary.
I'll be getting 20 of the slaves printed at the same time. I'm tryng to shrink them as much as possible to get the printing costs down but I want to keep the power traces fairly wide to keep the risk of burining one down to a minimum. I guess since I'm using professional boards, I can get the traces a bit closer then what I had but still there are a lot of relays that need to go on one board. When they come in, I should be able to send you a fully functional relay board also. I'm going to have to order more relays so you may as well have the same setup on your end. It's kind of a big risk for me to do that big of order based on the assumption that I have everything correct on the layout. I also need to change the layout of the relay boards, They are currently 8x10 and I need to drop it to at least 7x10, or 7x11 to fit in my enclosures.
If you keep traces short 40mil will do for the power traces

One slave and one master would be all I need, and I will return them when you are happy with the software. I will be having some boards made that can be used for testing, but I will not have time to do that until late September at the earliest.
How short is short. Most of my traces for the power right now are between 2 and 5 inches. Each group of 8 relays goes back to a pin header in the center of them. ·
As for how short is short the shorter the better but the pulse is so short that you can cheat trace widths
My best guess is you will not likely blow a trace

After Looking at my Relay board, I see I can save A LOT of space on my traces.· The traces I have activating the relays back to the Tpics are way bigger than they need to be, so I should be able to shrink the boards by about 30%.·· cheap cheap cheap.
this topic has more posts then i have ever seen on one topic (i Think) but anyhow the project totally confuses me with programming but wiring is my specialty no i wont be of any help lol i just cant wait to see the finished product

Lab Rat, You are correct, I've looked through the forums and this post does have the most views and posts. I'm sure a quite a few of those are Kwinn, Mctrivia, and myself, but I'm sure a lot of other people have been keeping up on the progress of it. For what started as a "how would I do this" post, it's turned into an international project, literally, and has spawned another whole pyrotechnics firing system aside from this one that Mctrivia has taken on himself. I should probably compose a summary of the system on the other forum that Kwinn started for the hardware/software updates, one of these days anyway.
Lab Rat, that's sort of what I said a few posts back. One of the reasons for that is that there are three of us involved, each with expertise in one of the three areas needed by this project, so the target has been moving as we try to reach it.
The hardware is very flexible and can easily be modified for other uses, and I plan to do the same with the software after I have this project working
well. I plan to use it to do a bit of home automation (water garden, turn lights on/off, adjust temperatures, etc).
Everyone please feel free to post suggestions for changes and functions you would like to see on the propeller forum thread.
The redesign of the relay board is coming along nicely. So far I have managed to take off about 1/4" per group of 8 relays vertically so about 2" total shorter and about 2" narrower by being able to use smaller traces and the plated thru holes. Total size of a relay board will now be about 6"x 8.5" which I feel is very good for fitting 56 relays and all of the control chips. I may be able to take off another 1/2" here and there, but I'm starting to push the limits of the spacings now.

chaosgk, can you post the layout so we can look it over and possibly make suggestions?
PS, have completed the relay turn off function so I am pretty much done except for testing it. Not practical to test it on hardware I have. When do you anticipate being able to send me a master and slave? If it will not be by the end of next week I should probably build something on a perf board for testing before next weekend.
oh and i hat to burst your bubble but i already have some networked solid state relays the only problem is i havent yet to figure out how exactly to program them i know how to turn them on and off one at a time but thats about it and it is by no means programmed when i do it lol·they are networked via 5 conductor wire and 2 for the 5 volt lines so a total of seven wires

and yes they do exist they are just expensive as all hell and would be an outrageous price for your application for the quantity you need but the only thing i question is are you going to be able to have an infinate number of slaves boards or is it only limited by how far one is willing to go to program the beast

The $100 coin is 99.999% gold.
We are also the only country to be able to make electroplated steal coins. This makes them much cheaper and why we make coins for a lot of different countries.

LabRat, the master controller we are working on is capable of controlling 16 slaves. Theoretically, the way it is done it could control a lot more, but there are practical limitations. The more slaves you attach the longer it takes to send data to all of them. As long as you only need to send data to a few slaves during any time period that is not a problem. If however you need to update a lot of them frequently it becomes an issue.
Short answer, no it can not control an infinite number of slaves.
Mine can though. 100000000 slaves with 128/slave is the max number at present but that is a code restriction using 8 digit decimal number to refrence each

16 slaves at i think you said 56 relays per slave that would be 896 relays that would make a nice display but what i questions is why didnt chaosgk purchase a premade computerized firing system that is on the market for professionals instead of making one what is the cost of one of them and what is an estimated cost on the master and price per slave and once done would you be willing to produce more of them and maybe sell them in kit form with just a paper saying what component goes where on the board that would be great i would consider buying one or two if its not too expensive

At the end of the program is a table of longs, the first one being labeled table (naturally) those are the "instructions" that make up the firing sequence. In this case the program selects each slave in turn, downloads 2 relays to be fired and fires the relays after 2 seconds.
