Mask Sanitization That Anyone Can Build

Mask DIY sanitization device on the left, mask used as an example on the right. The device is a Tupperware-like plastic container, on top, a small motor plus battery device with an alligator clip attached to the motor. Mask is inserted into the container through the opening on top, hooked to the motor, and the motor then spins the mask inside the container where hydrogen peroxide vapor is being misted.

We’ve seen a wide variety of mask sanitization solutions, and now, [spiritplumber] from [Robots Everywhere] brings us a frugal and ingenious design – one that you barely even need tools …read more Continue reading Mask Sanitization That Anyone Can Build
