But they're bloody expensive and quite fragile. The cheapest unknown-brand ones I've seen on Chinese websites is ~ $100.

- nomel 11y agoOh come on. Some fine thermocouple wire wrapped around a literal hot wire would be enough, no need to use industrial grade scientific equipment.
- semi-extrinsic 11y agoThat wouldn't give you anywhere near the resolution of an actual hot wire anemometer. I'm fairly confident your instrument would be limited to measuring "is the wind below or above 60 mph?", and would be unable to resolve changes happening in less than ~ 10 seconds. Real hot wires have a diameter of ~ 1/100 of a millimeter, that's the only way to achieve any useful level of sensitivity.
