Right now, before christmas day my electric hair cutter is broken. The adapter has fall down and this shit is not working anymore, the little red led is absolutely not blinking. So the cable is useless. But sure I did not want to go next day to the barber cause I do not like it and have lots of other things to do. You know it's christmas time.

I was thinking: what is inside of cutter, what's the heart of cutter? A little gear motor that functions from 4-5V. And where do I get 4-5V constantly? From USB cable. Solution: get an old any telephone USB cable, cut the useless mobile socket, bind the thin cables to the socket that's going to the cutter (which ones? at USB the red /VCC/ and black /GND/ are the winners) and use electrical tape. Voala!



10 mins tech maintenancing and tomorrow not going to barber. Smile!
