Absolutely, that sounds like a great project. What are the main specs you’re targeting for the purifier? Let’s start by lining up the key components and the energy budget.

That sounds solid overall, but a few things to double‑check. A 1.5‑liter‑per‑minute flow through charcoal, ceramic, and UV can be tight on pressure; make sure the pump can handle the head loss, or consider a multi‑stage pump so you don’t lose efficiency. Also, with a 12‑V pack under 10 W, you’re looking at about 5 Ah to hit a day’s output, which is doable but leaves little margin if the panel’s output dips—maybe add a small 1 Ah buffer or a low‑dropout regulator so the UV LED stays bright. Sizewise it’s portable, but keep the UV chamber sealed and maybe add a safety lock so it’s not exposed to accidental touch. If you can get a small flow sensor to monitor real‑time, you’ll know when to swap the filters and keep the system running clean. Overall, I’d say you’re on the right track—just tighten those margins a bit and we’ll have a reliable purifier for the colony.

That’s the spirit—every detail matters when lives are on the line. The two‑stage pump and extra buffer should keep the flow steady, and the LDO will protect the UV chip from voltage spikes. Just remember to test the latch under load; a quick drop‑test can save a lot of headaches later. Keep iterating, and we’ll have a device that the colony can count on.
