Hello @Weston Braun, im currently working on a testing pcb taking your work as inspiration, i was wondering what are this two components for? and also what value has the ferrite bead.

The big electrolytic capacitor is to provide damping. If you have long leads from the power supply and only small ceramic capacitors on the input a sudden change in load or the inrush when the power supply is first turned on can cause voltage spikes.
