The question "What can make out printed circuit boards?" struck me. PCBWay and many other board producers sell prototype friendly 2 sided printed circuit boards for 5 dollars or less (plus shipping). Armed with the fact that it is 5 dollars whether I order 1 or 10 boards, my question became "What can I make out of 10 circuit boards?"
Since I play Dungeons and Dragons, the handy shape of a 10 sided die came to mind. I set about designing a circuit board that could serve as all 10 sides of my desired decahedron.
The first phase of this project with attempt to answer the following questions:
- How do I design plated edges or castellated holes so PCBWay (Current Fab house of choice) understands what I want?
- How well does lead free (SAC, leftover from another project) solder hold up as "weld" between PCBs?
The second phase, if this project is continued, will attempt to put a microcontroller and IMU into the decahedron, and recess the LEDs so I can roll the LED like a normal die. If this fails, then the decahedron will just need to be relegated to babble or desk ornament for my dungeon master.
