Clever build to make finger joints with a table saw

Not even using the jointer blade too.  Just a standard table saw and the sled is nice and small (so portable).  The author uses an arduino to count steps on the crank.  Too bad it didn’t use a stepper to automate that bit.  Unfortunately the author does not seem to have a link to plans or code for this.
