| - | The original boards were done on perf and was an eye-sore. But it featured USB HID functionality, essentially based on keyboard triggering, but allowed the lighting of LED indicators which is a limitation in regular USB keyboard PCBs. | + | The original boards were done on perf and were an eye-sore.

| It was designed with good old pen and paper to sketch out a rough component layout (now lost) but I still have the SVG that it was moved to: | It was designed with good old pen and paper to sketch out a rough component layout (now lost) but I still have the SVG that it was moved to: | ||

| - | Spent the time hand-routing the traces paid off. When my boards arrived, I popped in the pre-programmed PIC (dip package) and connected it to the test harness. To my absolute delight the design worked first time, no patching or re-spin required. | + | Spending the time hand-routing the traces paid off.

| When working in KiCAD, I used the printout of the original SVG diagram and highlighted each trace on the paper as it was laid down in the new design. This way I could slowly cross reference each trace and have a fair level of confidence that each was correct. | When working in KiCAD, I used the printout of the original SVG diagram and highlighted each trace on the paper as it was laid down in the new design.

| - | Even though having spent time on the design, it's always interesting to see how the board appears much smaller than what you had in your mind. Like people on television. | + | It's always interesting to see how a board always appears much smaller than what you had in your mind. Like people on television :) |
| To access more information about the Virtual Pinball schematics and PCB gerbers, these are available at: https://github.com/sausagejohnson/pinball_pic16f1455. Eventually all parts of the project: the frame construction, game software, controller hardware, and controller software will be opened up to allow you to build your own machine. | To access more information about the Virtual Pinball schematics and PCB gerbers, these are available at: https://github.com/sausagejohnson/pinball_pic16f1455.
