The Lucid Dream Machine

Step 4 The Circuit Board/Schematic

We used a custom circuit board to make the end project look much cleaner for instructables (and the watch battery holder only worked on a custom PCB). The Circuit board pattern and schematic is posted below, but if you choose to make a PCB it's very likely that you have to redesign it because you won't have the exact same pieces as we do. We left a lot of wire pads so that it would be easy to upgrade in the future (such as adding more switches, LEDs, etc).
