Matthias Wandel came up with a wonderful solution to making accurate cuts on his table saw. Best of all this system was built from scrap parts from a junk bin. Watch the video to see this cool machine in action. Make sure you check out the rest of his wood working tips, tricks and projects here."Going through my junk bin, I found a circuit board with 11 power transistors on it that suspiciously looked like it might have been used to control a stepper motor or something like that at some point. Working out the schematic from the traces, it was almost what I needed for my purposes. I cut out the part of the circuit board with the transistors and a few logic chips with a Dremel tool, changed the wiring of the diodes on the board to act as catch diodes, and soldered a printer cable to drive the logic side. Then I started playing around with hooking up stepper motors to that board."
