I wanted to embed an Arduino with a tft touch screen shield in a wood block. The wood block, made from a 2x4, already had a nice chamfered edge. Without access to a CNC, I had to get creative in this fabrication.
I started by measuring the touch screen with a digital caliper. Using a square, I transferred those measurements to the wood block.
I set up a jig on my drill press so I could move the block along the screen edge. Using a bit with the drill set to a depth limit I outlined the screen area that would be removed from one side of the block.
Next, I loaded a Dremel cutting bit into the drill press and cleaned out the perimeter.
Next, I flipped over the block and set the depth limit deeper. I outlined the Arduino mounted in a 3D printed bracket on the back of the block. Using the bit and the cutting bit again, I removed the area where the Arduino and screen would be mounted.
I used the combination of bits to carve out areas for the bracket to screw into the block. I used 3/4" wood screws.
I did a somewhat crummy job of carving out slots for the USB and power connections: I need to revise the power hole and 3D print a faceplate to cover up the mistake.
I am running a sketch that comes with the Seeedstudio tft touch screen library that makes the screen act as a drawing pad. It works so well with a Palm pilot stylus that I found years ago and threw in a drawer.
