Dave, while watching the video on the Jaycar LED Lights, you were showing the menu on the interface box and saying there was gobbletygook on the display. I thought this too initially, but after a few seconds I saw what is happening.
When you first turned it on that it showed what looks to be "E 45", but it's actually "Sh 3" upside down. If you turn the interface box upside down, you'll notice quite a few readable words (?) on the display. At 3:55 it looks like "SLae", at 4:03 it's actually "Addr", at 4:04, it's "SLnd", at 4:06, it "Chnd". etc., etc.
I don't know wexactly what they mean, but I'm sure "Addr" is address, "CHnd" is probably channel, etc.
Just wanted to let you know the observation I made. Although several have likely already alerted you to it.
Keep up the good job.
Regards,
Jim
