I built a weather program that is near 95-98% accurate with current sensors, but to me that was not good enough. I really needed a wind speed sensor. I just seen a AS5600 rotation sensor posted by Adafruit and it dawned on me that this is more than perfect, I can build a 3D printed cup micro anemometer! I have the 1mm pins, 3x3x3 magnets, low friction bearings, and professional 3D printed parts on the way...

Basically I’m building a compact, rugged wind sensor to bring real wind speed data to my portable AI Field Analyzer. Most “handheld” weather gadgets skip wind entirely though I wanted something better for field forecasting and storm alerts.

How it works:

• 3D-printed micro cup rotor spins on 1mm steel shafts and 681ZZ ball bearing for ultra-low friction.

• AS5600 magnetic angle sensor + 3x3x3mm N52 magnet tracks absolute shaft rotation, turning every breeze into high-res data, no gears, no slip rings.

• Shown with a banana for scale and mounts right to the analyzer’s case.

Why this matters/important :
Wind speed is key for early storm prediction, AI-based weather analysis, and real microclimate logging. With this setup, I can catch wind spikes that most portables miss.

Parts on order:

• AS5600 sensor, N52 magnet, 681ZZ bearings, 1mmx14mm rods, SLA-printed rotor/top (Accura Xtreme White 200).

Next steps will be:

Assemble, calibrate with a reference anemometer, and integrate with my weather algorithms. STL and code coming soon—banana not included (that's mine lol)
