Mnemo

Mnemo answers one question I used to ask constantly: do I already have one of these, and which bin is it in? It’s a self-hosted inventory system for the electronic components, hardware, and assorted parts that pile up when you make things.

Why no live link? Like Calliope, Mnemo runs on my hardware behind a login. Screenshots and the source tell the story here.

What it does

• Catalogs parts with quantities, locations, datasheets, and metadata.
• Fast search so “do I have a 10k 0805 resistor?” is a two-second question.
• Tracks where things physically live — bins, drawers, shelves.

Stack

Python backend with a React frontend, mirroring Calliope. Runs alongside it on the same self-hosted box.

Notes

Built it because a spreadsheet stopped scaling the moment I had more than a few hundred distinct parts. Now it’s part of the daily workflow at the bench.
