\subsection{LM317}
As the viewfinder needs its own power supply, I need 7V from 12V. Parts box has LM317.

\begin{verbatim}
Formula for LM317:
     Vout = 1.25 * (1+ R2/R1)

           R1 = vout to gndpin
           R2 = gndpin to gnd

           e.g. 720 R2, 240 R1 == 5V
                1K R2 == 6.45V
                1.1K R2 == 6.97V
                
\end{verbatim}
\textbf{Standard R1 is 240ohm}, so let's keep to the standard.\footnote{Check when looking through devices that use LM317, which adhere to that standard. They should, when possible. Standards should always be followed.}

Make sure to \underline{account for the drop out} needed for Vin to LM317.
