Thanks for that. Either thats new or I somehow missed it when I was looking before. I've been running this board for quite a while inside of a zip lock container. I really need to move on to the next stage of mounting this up in a box before I break something.
I was originally going to use a toolbox, but I'm beginning to lean towards a computer case. First, I could use the power supply for DC power. Currently I use a cell phone charger. Also, I could use fans to cool heat sink mounted SSR's.
The beauty of this thing is you can control eight different things pretty easily, but you are limited to where you can run an extension cord and phone cord (or stereo cord) from the unit. And you can monitor and control all these things remotely.
