There isn't any rational reason that an AC motor with a few resistors/potentiometer with a filter isn't the cheapest. DRM would involve DC power which means a transformer is required as well. Unless there was a good reason to have a DC motor, this wouldn't even be an issue for anyone who can combine a box fan with a filter.
I was building a DIY filter and took apart a purifier and was disappointed at it not having DC for me to connect my esp to for a sensor to check the purity.
- wging 3y ago“DRM” means “digital rights management” in this context; it has little to do with the choice of AC or DC power. What acronym did you interpret it as?
- graphe 3y agoDRM as you used it. There is no DRM AFAIK that works on AC power. It needs binary and that needs at least a transformer.
- alias_neo 3y agoI interpreted their point to mean; if the device doesn't have any DC voltages inside, it's not running transistors or micro-contollers; the D in DRM; i.e. "no smarts". No smarts, means no DRM.
