Need both 110VAC and 12VDC for your project, but don’t want to deal with those pesky switching power supplies?
Then you can do what they did in this PZ6 Corona Hybrid Ozonator - get out the hot melt glue gun and tack in a wall wart. You might even get solder to stick to the plated AC prongs. But just in case, wrap a good, tight loop of wire around those prongs.
Heat shrink? Bah! That’s for wimps.
And while you have the glue gun hot, why not use it to just tack everything down -
What could go wrong? It’s just an ozone generator!
