Hacking the SX2 Mini Mll

Jeffrey Nelson bought the SX2 HiTorque Mini Mill but didn’t want to drop $125 for the tachometer add-on, so built his own.

I knew before purchasing this mill that it had a tachometer display port on it much like the SC2 Lathe has. I also knew there was no way in hell I was going to pay 125$ for what amounts to an lcd and simple uC. So what’s the logical thing to do in a situation like this? Hack it!

He’s offering a kit if you want to build your own.
