Hey Product Hunt community!

As a serial maker, my biggest challenge has never been "what to build" it s deciding "what NOT to build."

Right now, I have over 50+ software ideas sitting in my backlog (from AI tools like ManyGPT and HeyAxo to specialized funnel builders).

When you have a long list of ideas, the temptation to jump straight into coding is real. But last year, I wasted weeks building a product that no one actually needed because I skipped validation.

Since launch, the most common first project hasn't been what I expected. I assumed smart home sensors. It's 3D printers.

The pattern: an ESP32 wired to the printer, one HTTP POST when the print finishes, a notification on the phone at 2am. Total firmware footprint is about a dozen lines, and the sketch is in our public examples repo.

A few other builds that came through the delivery logs and community submissions:

A garage door that complains after ten minutes open. A mailbox with a magnetic contact switch that pings when real mail arrives.
