I had my friend do this custom "Flashing Stop Sign" while doing "social distancing". Shipped all the parts to Keith.
Keith built a custom bracket to hold the "STOP" signal to the "Brass pole". I found the Brass pole at a flea market.
Also, provided the flashing circuitry that runs off a 12V supply.
I wish I had the "talent" of Keith's.
