Re: [Homebrew_PCBs] PCB drill

2003-12-12 by Ted Huntington

That looks impressive.   I guess those are bipolar motors that you
attached to gear reducer heads and control with a serial/parallel
port?    That is interesting that you were able to use brackets that a
person can buy at most hardware stores I guess.  Can you use a drill
file from software like Eagle to do all the drilling from the diagram
automatically?  I guess because you have to change the drill bits by
hand, you have to edit the drill file then.  Are you using a chip like
the HIP4081A or a PIC like PIC16F77 to control the motors?

This person has a useful tutorial on a home-built PCB drill/mill:

Thanks
