Hmm, believe it or not I'm actually thinking of a way that I can probably do something like this...and with things I already have. It would require some setup and testing of course, but I might give it a go. My German sub is overdue for a visit, he was supposed to visit in February, then March, but with the whole Coronavirus situation, obviously that's all on hold indefinitely now since he's traveling from Europe to the US. But once that all blows over and he makes it here for another visit, maybe I'll rig this setup when he's here...and see how he does. And if I do, of course I would have to make sure I get a video of it since I know many of you would love to see this in action. ;-) Unless any of you would NOT like to see that in action? Anyone? Anyone? Haha
