Ventilated mouse

A real man solves a problem not when it originated, but when she got it completely. So I completely got the fact that when working with a mouse sweats palm. Searching for the nearest supermegagipermarket gave nothing, so it was removed from the closet an old optical mouse and a tiny fan.

Ingredients: screwdriver, drill, lining, digital multitester, special abrasive paste, a little glue and a desire to distract the head from the monotonous work. Fifteen minutes - and the back of an old mouse turned into a fine sieve, through which a fan quietly blows from inside, pleasantly cooling the palm.

Of course, I had to sacrifice two internal fixings and stupidly replace them with glue. But the satisfaction of the device is simply invaluable :-)
