Parts list
12v 1.25 amp dc coverter
Stainless steel picture hanging wire
Pill bottle for the switch holder (u can improvise anything as long as a switch and some wire can fit in it)
Two wire cord not extension cord like dc wire cord i will ad pic later
Tubing you can get it at menards by the pvc its the 3/8 flexible stuff comes in blue redand white( i used tattoo tubes since i made a handheld one and have bunch of tubes left from when i did tats)
Then a carbon piece some used carpenter pencil lead but i found those fail and break down . So i ordered bunch of small motor brushes on ebay . Dosent break down in tank.
Hot glue gun probably can use silicone also
Shrink tubing
Acid etching flux
Soldering iron and solder
Drill
And a momentary switch.
So most of this you may have laying around already at least the tools.
