I hate that i have to manually crank my table saw. So im automating it.
3d parts are published on thingyverse. You will need to adjust to fit your own saw
Arduino mega 2560 code is here. Version 1
Electronics schematics is here.
PS: You will have to modify your table saw for this to work and it will probably void any warranty. You schould have a fair understanding of mechanics and electronics before starting this project.
Additional PS: This is free and i dont provide much in the way of support..
