I like the idea of
"Turning a hairdryer into a COOL blower" as discussed in the very old thread:
https://forum.allaboutcircuits.com/threads/turning-a-hairdryer-into-a-cool-blower.21823/
I would like to make one strong wind cool blower to blow away dirty air spread from the nearby environments from time to time. I will do it based on a hair dryer ( with its very high rotational speed compared with some big sized fans ) with two switches. One turns on-off/low/strong wind and another low/high heat.
So if I want to bypass the heating elements. I need to reconsider the design just to bring a 240V ac down to 3V dc?
How can I do that safely?
