CNC YEAH BABY

My First PCB Design

25 February 2009

Pretty proud of this. My swap with Steamboat Ed leads me on a three week odyssey through the vagaries of PCB layout, a completly new skill for me. Results thusly. Is that not a gorgeous thing? It's colorful and yes, I hung it on the wall in my room.

Schematic and board designed with EagleSoft EagleCAD free PCB software. Knowledge by Instructables, couldn't have done it without the Instructables.

What is it, you ask? It's a driver circuit to control 12 valves from a BASIC Stamp microcontroller. It's the board for Steamboat Ed's calliope (like a pipe organ).

Here's a shot of a test-fit of some of the parts.

The Round Maze

Our first creative part, we designed our own round mazes. This was REALLY hard to draw, egads.

The Square Maze

This was hard, very challenging to draw. Amazing accuracy of this little machine. Something like 6 passes to cut out the grooves. First time with the engraver tool, which is a left handed center drill to a depth of 7 thousandths.

Hexagon

Drawn, CAD, CAM, and G-code in Emco WinCAM. Cut on Emco PC Mill 50. Our second CNC mill assignment.
