Used a small welded canister made of 1 inch square tubing.
Steels are "high carbon ball bearings" (off of Amazon, unknown alloy), and 1090 steel powder.
Acid etching produced disappointing contrast, so I went wild and used electrolysis in brine.
Whee!

*That said...* For an actual practical "production" purpose, I would still recommend a library like Numpy for signal generation. The performance impact of doing math in pure Python (as opposed to compiled C-accelerated code) is big, especially when working with 16+ bit, 44k+ Hz audio samples.

Third party libraries come with all sorts of hidden costs, like trouble running on uncommon platforms (e.g. Raspi), difficult version control, etc. An independent script is valuable for portability and for demonstrating the fundamentals of what you're doing.

I was thinking about what it would take to create my own software "modem" to use in digital #hamradio communications, and was frustrated by the pervasive recommendations to use third-party libraries, when Python's built-ins are more than enough.
