Lee,

The load is AC, it’s a low voltage AC but the phototriacs make it easy to switch.

Since the load is pretty low amperage and is just DC i wasn't sure if you really needed the phototriacs.

I found this article very inspiring. I was searching for a easy solution reading some switches into my nslu2 when I stumbled on this article. My first idea was using a USB -> Parallel converter and writing some code myself, but the Bit Whacker sounds more more appealing.

I deleted a comment from sofiaa that implied it was a link to a site with more informaiton, in fact it was a spam link to a site doing PCB work. The site was Rush PCB. Please join with me to boycot this company. I plege never to consider this company for any purpose. All,

I have the same Hunter controller for my sprinkler system. Last winter I wired all of my eaves so I could run Christmas lights around the entire house and used my Hunter controller and a few parts including relay and rectafier to turn the Christmas lights on and off. Your project is a little above my head, but I am definately going to study it and try to make some use of it. A big thanks from Boise Idaho! I love your project.

But I'm curious (new to embedded Linux) about including PHP support in your Linux build. Was that build in as part of the image? Or added afterward? Also, were you concerned with the image's size? Thanks. Great project. But I’m curious (new to embedded Linux) about including PHP support in your Linux build. Was that build in as part of the image? Or added afterward?

The USB bit-wacker is a PIC with a USB to serial adaptor and some nice firmware. If it does not directly support your needs you might be able to do some custom firmware. You could also use the Ardunio with some home grown software. RonG,
