Prototyping the Circuit

The Electronics Team has been hard at work finishing up the design for the basic circuit.  While we are waiting for the Build team to finish the frame, we are making a setup of all electrical components that will be inside the printer. The piece we have found most recently is the PNP MOSFET, which will allow the circuits to be run at varying voltages. This device (shown above) allows us to power the gate pin, which will in turn allow current to travel from source to drain.  This allows us to run some things (like the stepper motor) at 12V, and others (like the smoke sensor) to be run at 5V.  This can all be run from the singular power button that will enable the entire device.
