I wonder if it would be possible to use this data to create an LED candle with a super-sensitive microphone that would realistically flicker when "disturbed", otherwise be a mostly consistent brightness.
Or are there better sensors than microphones to detect air disturbances?
- detaro 11y agohot wire aenometers can detect even tiny air movements
- semi-extrinsic 11y agoBut 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.
