I found this randomly when I was browsing a favorite site of mine, Gizmodo. Check out the amazing saw that won’t cut your finger… well… too much!
Check out the video:
So here’s how it works:
The SawStop safety system includes an electronic detection system that detects when a person contacts the blade. The system induces an electrical signal onto the blade and then monitors that signal for changes. The human body has a relatively large inherent electrical capacitance and conductivity which cause the signal to drop when a person contacts the blade. Wood has a relatively small inherent capacitance and conductivity and does not cause the signal to drop. A fast-acting brake stops the blade when contact is detected.
Maybe it’s because I used to do carpentry stuff now and then and know saws and the damage they can do but… this amazes the fuck out of me and I say it rocks like nothing. Screw the I-Phone — I want this.
