OK, I had no idea what this was for, so I had to find out!
Apparently it’s a light-controller board for a Ridgid Flatpack/Compact pipe-snake camera, basically a pipe inspection tool to check the condition inside sewer lines and similar pipes.
I have no use for such a thing, but if you do, this type of board is going for around $400 on other sites, give or take, so this would probably be a pretty good deal!
Oh, so random.
Uh, grab em while you can??
What would Edison do??
And to think I almost pulled the trigger on the L-shaped pillow for my wife when I could have one of these!!! LOL
