Slow Delivery - New Project

I’m still waiting for that replacement LCD to arrive from china, i’ve ordered another from a UK seller.

I’ve not been sitting around twiddling my thumbs though; a while ago i saw a schematic for a stepper motor driver on instructables. It seemed a little over complicated to me and i figured i could easily build one using one of the PIC microcontrollers that i have, so i set about designing a cheap 3 channel stepper driver using just a 40 pin PIC and some mosfets. The advantage here is that i can give it a number of interface options such as a parallel interface, an RS232 interface or an I²C interface. There may also be options to include an LCD for status display.

The stepper driver circuit had reminded me of another one of my projects and i got the itch to start it. This is my CNC project. Its an MDF construction and the plan is that it will eventually be able to build a better version of itself. I’ve already started construction so I should soon be posting my designs.
