I need a new place to buy electronic components and some mildly niche circuits/products that's not Amazon. I'm currently looking for an adjustable temp fan controller for an indoor green house. It's sitting in front of a Window on a shelf covered in plastic. I want to add a 12v dc fan to the top to turn on when gets somewhere around 90 degrees farenheit.
I used to use parts-express.com, but it looks like they mostly just do audio now. Does anyone have any good recommendations for purchasing things like this in the USA.
