The fan gives you coolness on a hot summer day. The heater inside provides you with a warm breeze in those cold winter months. This fan/heater comes with a ambient led indicator: cold=blue, warm=purple. The fan speed and the amount of warmth can be fine-tuned.
As an extra it is suitable for extracting harmful solder fumes. Replace those bulky desk fans with this smaller more convenient fan.
The total cost of the desk fan/heater = 7 dollar. The only part I bought was the PWM dimmer, all the other parts were laying around in my garage.

Step 2: Sawing
The final product will be a cube. The wood I used is 9mm thick so every measurement is made keeping the thickness of the wood in mind.
Saw 2 squares of 12x12cm, 3 squares of 10,2x10,2cm and 2 rectangles of 10,2x12cm, 4 little rectangles of 1x1,5 cm.
Saw 2 pieces of 3cm from a wooden stick (12mm in diameter).
