I am looking to buy SSR4 pcbs, since RJ is out of them. If you have any let me know.

Thanks
 

Yes I did plan on designing my own board this is not a copy of RJs board, it is based on the SSR4 circuit though. If RJ doesn't want me to make a new board based on his work I wont. I respect all that RJ does and I don't want to step on toes.

And again I am not running a coop I was just wondering if anyone else would be interested at this point. I was just trying to decided if I should design a one sided home etch board or a 2 sided manufactured board.

parts for one would cost $20.46 from mouser. This would go down if multiples are ordered.

The board will fit in a keptel CG1000 or CG1500 (~$20) 

I am using the same parts as the ssr4 with the exception of using resistors instead of the SIP, the sip saves board space but is always back ordered

Would anybody be interested in a ssr8 pcb for use with the freestyle?

After this Christmas I realized that I wanted an 8 channel ssr for use with arches and bellagio fountain poles. So I am in the process of making one. I use freestyles so I am not adding a dmx option to the pcb, which also makes the circuit very simple. The SSR8 would take 2 cat 5 cables from the freestyle. Basic set up would be 2 cat 5s from the freestyle, one power in, 8 channels out in one box.

My question now is whether should home etch the pcbs I want or have them made. The only way I can afford to have them made is by doing a coop. If there is enough interest I will design the board for manufacturing. If there is not I will design it for home etching.

So, anyone interested?  I am expecting the pcbs to run around $5 each if I get 50 made and of course less for more pcbs.

This is not a coop yet!!! I am just trying to gauge interest to see which design route I should follow. I appreciate your input.

Four please

Thanks

Ive been doing lots of research on el wire. That harp is very cool Dilip. I found this article on a guy who made a midi controlled el wire setup

He uses triacs to control the el wire, same as an SSR4.  The triacs in an ssr4 are capable of controlling the the 120v 1500Hz voltage used to power el wire. The optocouplers in the ssr4 should keep the rest of the circuit safe from the wacky voltage.  SO....

If there is any one else trying to use el wire you can do it two ways.  Option one you can use a DC controller like the MR16 attached to transformers that power the el wire, for each wire (channel) you control you will have to have a separate transformer.  Option 2  you can get one of the large ac frequency transformers, one of the one that powers 100-300 feet of el wire  and use ssr4s (with out the dmx option). Instead of plugging the ssr4 into the wall (mains) use the output of the ac transformer to send power to the ssr4.  Then the el wire attaches directly to the ssr4 channel outputs.

I have tested option 2 for short amounts of time ( a few minutes ) and it seemed to work fine but I don't have the el wire integrated in to my display yet so I don't know for sure if I will have any problems with it after running them for a few hours or days, hopefully the triacs can handle it with out heating up too much.

As far as I know neither option will let you dim the wires, the brightness of the wire is determined by the frequency of the voltage not the power. The guy who did the midi controller dimmed his wire by rapidly blinking the triacs on and off, im not sure this is possible with the current setup.

Has any body used EL Wire before?

If so has anyone done the blinky flashy thing with it? How did you do it?

If you dont know what El wire is you can google it or take a look at thatscoolwire.com.

I saw a video of someone using an MR16 to control the El Wire, (You are not allowed to view links. Register or Login
