When designing PCBs that will be produced professionally (or even if you etch yourself) it is sometimes hard to get a good view of what they will look like. Most CAD programs view the design in a way that is useful during design but that is not what they will look like in the end. Some provide a view mode or 3D rendering option to get a good idea, but at least CadSoft Eagle does not. What if you want to view what your design will look like or if you just want a fancy graphic to show off your wonderful PCB? Photoshop comes to the rescue.

This 12-keys keypad failed after years of daily use. No schematic or replacement parts from the original manufacturer. The only option was to replace it with an off-the-shelf telephone-style keyboard. However, I had to discover (by reverse-engineering) the original connector pinout to adapt the new keyboard. Following the maze of each and every PCB track in a circuit is boring and error-prone, so I looked for an easier way to get the job done.
