I got a project to suggest for you.
We need a mount that can be added to a light switch that you buy at the hardware store that allows you to mount a sainsmart type 2 relay (or just 1 relay either way) module to it. (I will draw up a picture in a little)
If you make one send me a link to your video or web page, or blog, or design file on one of the 3D printer forums and I will post it to my Tools of the Trade page.
If you aren’t asking too much I will probably buy a couple from you and do a post on what I think.
