Project – Hobbybotics Optoisolated Relay Controller

I have added a project detailing my design for an optoisolated relay controller.  I was looking for a simple way of switching high current DC and AC loads without the added expense of SCRs.  I can use this board to switch on/off lamps, a spindle motor for a CNC machine, or the heating elements on the toaster oven I am using for my re-flow oven project (more on this later).  Excited?  No? Well, go and check out the project anyway as you might learn something or, in the very least, find something that I screwed up on.  If you find the later, please let me know.

Check out the project here or the gallery here.
