My shop has no windows so on nice days I like to keep the overhead
door open. Well some kid watched me welding for awhile then decided
it was safe - snuck in and stole my laptop computer that was connected
to my CNC mill.
Got him on video, filed a police report.
I need some kind of photocell and beam across the doorway to alert me
if anyone walks in. Can garage door safety beams be used? I have a
couple of friends that can wire up or build me a circuit to make them
work, I just don't know how the work, is there a NO or NC output on
those? I was told you cannot just jumper them out, so I'm thinking
it's more like a signal output rather than a switch closure output.
Large dog.
which reminds me...Ill be having another group of pups available in
the next 4 months...seems I didnt catch mommy dog going into heat soon
enough to put her in the kennel.
Not AGAIN!?! That's irresponsible, mon. 50 demerits.
sigh..yes indeed. I didnt get home for 3 weeks..and the ex is a
ditz.
