Fall is here ,shop heat really is not on yet ,each year i go through looking for some sort of immersible heater to fit into the cooler fill port.
I felt that if one could just bring the temp up a bit it would be good for the laser
I don't like running the laser below 17 degree c
Right now i have a 500 watt small heater that i run near the cooler to get the temp at 17 ,doesn't take long after for the laser to develop its own heat
I have looked at fish tank stuff but its too big ib dia,need something like the old solder iron ,plug it drop in the hole for sat 15 min and remove.
Anyone with ideas
