T-Shirt Cooler (Just for fun)
thingiverse
This is a portable device that allows you to attach a 120mm fan directly to your T-shirt. It's perfect for when temperatures are soaring or you're feeling restless. The circuitry comprises a step-up converter that boosts USB port voltage from 5V to 12V, powering the fan. A pair of alligator clips secures the device to your shirt, ensuring it stays in place. Keep in mind that some 5V fans might not provide enough airflow, but my testing showed they fell short compared to their 12V counterparts. If you're interested in tweaking this design, I've uploaded the FCStd file for FreeCAD, allowing you to make modifications as needed. For those who can understand German, I've created a video tutorial that walks you through assembly.
