The Build
Arizona summers make ice-only plunges basically impossible to keep cold, so I went looking for a stronger cooling option than the small chillers usually sold for this. Ended up adapting a mini-split AC condenser with a custom coil, which was the most technically involved part of this whole build and honestly probably overkill unless you're somewhere this hot.
Holds temperature reliably even in 110°F afternoon heat, which none of my earlier ice-based attempts could do.
