Eagle CAD Designs
Here are the Eagle designs for the circuit board.
The top layer features the logo of my high school and the words "thank you" written with metal traces.
On the left is a
functioning LED fader circuit, and on the right is a functioning LED blinker circuit. The traces of both of these
circuits are exposed (no soldermask) for visual effect. The components will not be populated when I give them to
my teachers, as the leaded solder and bulky components aren't very attractive. I figured just the idea that these
were functioning circuits was pretty cool.
The spiderweb mess of traces in the background will be hardly noticeable
and will be covered by the blue soldermask.
Finally, white silkscreen is used to accent some parts.
This is the bottom side of the board.
The yellow boxes and text are actually the white silkscreen for this bottom layer.
The upper yellow box allows me to write in the name of the teacher, and the bottom
box is for a personalized message. I think a fine-tip sharpie should write well on the PCB.
The bottom-layer circuitry should be largely covered by the silkscreen and soldermask.
The border of the PCB and the silkscreen boxes consist of bare metal traces.
