What electric parts do I need for setup the Dryer?
-> You can buy this fan in many computer-shops as spare-part. And instead of a Solar-Panel you can take a cheap Power-supply, 6-12 V Output. If you have one with a switchable Output-Voltage you can adjust the speed of the fan (and with that the Temperature). It helps having a cheap Temperature-Display in the dryer for to check the Temperature. But we have also a small electronic Temperature-regulator for to have more accurate-Temperatures.
