Nice find, thanks for sharing. I also have been looking for something like this, but the products currently available were way to expense, especially as you said for people with a lot of rigs to control.
Just to confirm is the relay board you are using the USR-R16-T? Also, it looks like it takes a 12V DC input for power, is that also correct?
Thanks
not sure about the model, but 12v yes.
As you mentioned it's a cheapest solution I could find, 50$ for 16 Rigs and I have 100+
There also a way to build one big relay module with arduino, but as I mentioned in previous posts arduino behaves not as good as I wanted plus the coding part was kind off hard for me, it has some minor issues, but those issues makes it useless. So this one is the best so far
here's a link directly from seller I have buying experience with, after buying it you should find official page to download app and software for windows. It's easy as hell.
