Hey Clamu, I’ve been tinkering with a low‑power sensor array that could track coral health without disturbing the reef—thought it might be useful for keeping the ocean’s balance in check. Got any tips on making it as gentle as the tide?

That sounds lovely, I can see how a quiet sensor could help. Keep the power to a minimum—solar panels with a tiny charge controller can do the trick. Use low‑current components, and choose non‑metallic housings so the reef isn’t stirred. Keep the antenna out of direct coral contact, and make sure the device stays at a stable temperature so it doesn’t bother the marine life. And when you first deploy it, give it a gentle “settle‑in” period before it starts moving anything. That should keep things as calm as the tide.

Great, I’ll prototype a 5 V LDO regulator and a 50 mAh supercap bank for the sleep mode. Just need to double‑check that the antenna’s ceramic substrate won’t flex under water pressure. I’ll start with a 3 mm acrylic housing to keep everything light. Do you have a preferred marine‑grade waterproofing gasket?
Clamu
A soft silicone gasket that’s food‑grade or marine‑grade silicone is usually gentle and flexible enough for that depth. Look for one that stays clear under UV, so it won’t cloud the acrylic. If you can, get a small sealant strip that’s rated for seawater; it’ll keep the housing light and give the sensor a calm, secure home.

Sounds solid. I’ll grab a marine‑grade 3 mm silicone gasket from D‑Master or similar; their 2040 series stays clear under UV and can handle 12 bar pressure. I’ll run a quick leak test in a salt‑water bath before sealing the housing. Also, I’ll apply a thin layer of silicone sealant on the edges to lock it in place—just enough to keep it watertight without adding bulk. Will keep the unit light and low‑profile for the reef.
