-\section{Introduction}
-
-The Wisconsin Photo-Reactor (WPR) is made to be easily assembled.
-This document is meant to help chemists accomplish this assembly.
-Each reactor has two major components requiring detailed custom assembly:
-
-\begin{itemize}
-  \item The 3D printed enclosure, described in \autoref{SEC:enclosure}
-  \item The drive electronics, described in \autoref{SEC:electronics}
-\end{itemize}
-
-With these two major components complete, assembly of the WPR is relatively straight-forward.
-Details of final assembly are described in \autoref{SEC:assembly}.
-
-Throughout this document we refer to an online repository containing source and design files.
-This repository appears at \url{https://github.com/uw-madison-chem-shops/wisconsin-photoreactor}.
-This repository contains everything including the source for this very document.
-
-A working WPR is made up of many separate commercially available parts.
-This guide assumes that you have already done the work of procuring those parts.
-The online repository contains several README files with detailed part numbers and suggested vendors.
-
-The WPR is a living project.
-We welcome and encourage duplication and modification of our designs and documentation.
-If you notice problems or omissions within this assembly document, please consider opening an issue or pull request.
-
-\section{3D Printed Enclosure} \label{SEC:enclosure}
-
-\includegraphics[width=\textwidth]{"./3dp-coverat.jpg"}
-
-The body of the WPR is made up of three main pieces:
-
-\begin{itemize}
-    \item Base, containing LEDs, fan, and drive electronics.
-    \item Top plate accepting reaction vials.
-    \item Chamber walls spacing the top plate at the appropriate distance away from the base.
-\end{itemize}
-
-The WPR base is the same for all reactors.
-Look within the repository in the subdirectory ``photoreactor-base'' to find design and production files to produce the WPR base.
-You will also need to print a cable anchor, see files in that same directory.
-
-The top plate and chamber height must be specified for the particular reaction vessels used.
-Four examples for different vial sizes are pictured above.
-Look within the repository in the subdirectory ``photoreactor-tops'' to find existing designs.
-We encourage you to design your own if none of these suit your application.
-Consider adding your new designs to repository so that others may benefit from your design efforts.
-
-When interacting with the design files in our online repository you will see several different filetypes.
-We have designed the WPR enclosure using Fusion 360, and have included those f3d design files for those that wish to extend or modify the designs.
-Interacting with f3d files will require a Fusion 360 license.
-You will also find stl files in the online repository.
-These are common 3D-model exchange files which can be viewed using any 3D modeling program.
-In fact, GitHub itself has a built in stl viewer which you may use to inspect our designs.
-
-There are many options for getting your enclosures printed.
-We recommend white PLA as a material, although any white material should work---we have also used ABS.
-If you are printing yourself, follow the instructions provided by your printer to produce slices and program your printer.
-Note that you will need support material for the base.
-Any company or shop offering 3D printing as a service should be able to accept our stl files without further modification.
-
-We have succesfully printed using the following printers:
-
-\begin{itemize}
-  \item Ender 3
-  \item Stratasys uPrint SE Plus
-  \item Ultimaker 3
-\end{itemize}
-
-Once your parts are done you may need to remove extra bonding material with a razor blade or exacto-knife.
-The three pieces of your reactor should fit together snugly and securely.
-

-\begin{center}
-  \includegraphics[width=0.5\textwidth]{"./heat-insert.jpg"}
-\end{center}
-
-Each WPR base contains seven threaded heat inserts.
-These allow components such as the drive circuit board to rigidly attach to the base via machine screws.
-Use a soldering iron to carefully heat these while pushing them into their cavities.
-
-\section{Electronics} \label{SEC:electronics}
-
-\includegraphics[width=\textwidth]{"./electronics-coverart.jpg"}
-
-The WPR incorporates small circuit boards controlling the incorporated LED and fan.
-We refer to these small boards as ``drivers''.
-There are two types available: the ``analog-driver'' and ``digital-driver''.
-Refer to the associated directories in the online repository for design files for each of these.
-
-Both drivers are built around Mean Well's LDD-1000L LED driver module.
-This module delivers constant current up to one amp.
-The current delivered can be controlled electronically in several different ways.
-WPR users wishing to understand this design should refer to Mean Well's datasheet.
-
-The analog-driver circuit is made to be as simple as possible.
-The circuit accepts DC 12 V through a barrel jack.
-A small knob is used to adjust light intensity.
-Fan speed is not adjustable.
-Refer to \autoref{SEC:analog-driver} for analog-driver assembly instructions and further explanation.
-
-The digital-driver circuit is made to be incorporated into an I$^2$C-based digital control system.
-In addition to power, these boards have 4-pin connectors to carry the I$^2$C serial data.
-The digital-driver is pictured above, without any connectors attached.
-Refer to \autoref{SEC:digital-driver} for digital-driver assembly instructions and further explanation.
-
-When interacting with the design files in our online repository you will see several different filetypes.
-These circuit boards were designed using KiCad, a free and open source electronics CAD software.
-All KiCad files are contained within the ``kicad'' subdirectories.
-You may modify and extend these designs however you like.
-
-Those wishing to reproduce our designs should refer to the gerber subdirectory.
-Within the gerber directory you will find zip files for each separate version of the PCB.
-You may upload these zip files to PCB manufacturers when ordering copies of our designs.
-
-\clearpage
-\subsection{Analog} \label{SEC:analog-driver}
-
-The analog driver circuit is meant to be as simple as possible while still allowing for reproducible LED intensity control.
-To this end, the number of components has been minimized as much as possible.
-A full schematic of the analog circuit appears at the end of this section.
-A bill of materials appears within the README of the online repository.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./bare-pcb.jpg"}
-\end{center}
-
-Your PCB manufacturer will send you a bare board, as seen above.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./surface-mount.jpg"}
-\end{center}
-
-Begin by adding the surface mount components.
-Recommend thin solder, e.g. 0.015''.
-The LED does have a polarity---ensure that the small green line points towards ground (left).
-Once done your board should look like the above.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./connectors.jpg"}
-\end{center}
-
-Next, add the connectors and the potentiometer knob.
-From now on we recommend standard gage solder, e.g. 0.031''.
-Once done your board should look like the above.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./barrels-tested.jpg"}
-\end{center}
-
-Next, add the barrel jacks and the test points.
-With these added you may plug in your board for the first time.
-You should see your power indicator LED illuminate.
-You should also be able to adjust the DC control voltage relative to ground by turning the knob, as shown above.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./pcb-driver.jpg"}
-\end{center}
-
-Finally, add the Mean Well LED driver.
-Note that this component goes on the back of the PCB, as shown above.
-
-\includepdf[landscape=true]{"../analog-driver/driver.pdf"}
-
-\subsection{Digital} \label{SEC:digital-driver}
-
-The digital driver circuit can be controlled from a computer or some other digital device.
-We built our driver to work over I2C, consistent with an emerging standard for many ``maker'' products.
-While the physical connectors may be different, our digital circuit is compatible with the following systems.
-
-\begin{itemize}
-  \item \href{https://learn.adafruit.com/introducing-adafruit-stemma-qt}{Adafruit STEMMA}
-  \item \href{https://www.sparkfun.com/qwiic}{Sparkfun Qwiic}
-  \item \href{https://www.seeedstudio.com/category/Grove-c-1003.html}{Seeed Grove}
-\end{itemize}
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./digital-wired.jpg"}
-\end{center}
-
-Each digital driver is based around an ATtiny85 microcontroller acting as an I2C peripheral.
-Multiple digital driver boards may be ``networked'' together onto one I2C bus by simply daisy-chaining the boards together, as shown above.
-In such a use-case you must choose a unique I2C address for each ATtiny85 peripheral.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./redboard.jpg"}
-\end{center}
-
-There are many ways to interface with the I2C bus.
-We have used a SparkFun RedBoard, pictured above.
-You may find an example within the online repository that dynamically controls both the LED intensity and fan speed.
-
-\includepdf[landscape=true]{"../digital-driver/driver.pdf"}

-\section{Assembly} \label{SEC:assembly}
-
-\includegraphics[width=\textwidth]{"./assembly-coverart.jpg"}
-
-Once 3D printing is done and PCBs have been filled, WPR assembly is fairly straight-forward.
-The various electronic components must be installed into the base (pictured above), as described in \autoref{SEC:base}.
-Reflective coating must be added to the chamber walls, as described in \autoref{SEC:top}.
-After these final steps, your WPR is ready for synthesis!
-
-\clearpage
-\subsection{Base} \label{SEC:base}
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./bare-led.jpg"}
-\end{center}
-
-If possible, it's best to order your LEDs pre-attached to an ``LED star'' heat sink.
-Otherwise you may order bare LED stars and discrete LEDs.
-Either way, you will have a filled LED star as pictured above.
-In this example we are using LED Supply part number 07007-PL000-F.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./soldered-led.jpg"}
-\end{center}
-
-Start by soldering leads onto your LED star, using the red positive black negative convention.
-Soldering here may be challenging, as the LED star itself will resist your efforts to heat it.
-Adding some lead-based solder may help, due to the lower melting point.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./tap-heatsink.jpg"}
-\end{center}
-
-The aluminum heatsinks arrive preformed but without any tapping.
-Tap the heatsink for imperial 4-40 machine screws.
-We used thread-forming tap: OSG 1400105300 with a pneumatic ``air-tapper'' (pictured above), but you may do this by hand if you wish.
-You will need to tap just two of the innermost holes.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./led-and-heatsink.jpg"}
-\end{center}
-
-Install the LED star and heatsink with wires facing towards printed hole.
-Use 1/4'' screws.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./mounted-fan.jpg"}
-\end{center}
-
-Install the fan.
-Pay special attention to the orientation of the fan, including the location of the cord.
-Use 3/4'' screws here.
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./cable-tie.jpg"}
-\end{center}
-
-Install the cable anchor using a 1/4'' screw.
-Use a zip tie to capture the fan cord, as shown above.
-
-\clearpage
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./driver-on-base.jpg"}
-\end{center}
-
-Install the driver board using the threaded standoffs.
-Plug the LED and fan into the board.
-Pay special attention to the orientation of the fan connector.
-You should now be ready to test your base---remember to use proper eye protection!
-
-\clearpage
-\subsection{Top} \label{SEC:top}
-
-\begin{center}
-  \includegraphics[width=\textwidth/2]{"./reflector.jpg"}
-\end{center}
-
-Simply cut the reflective material to line the chamber.
-It's good to leave overlap around the interior, as shown.
-Remove the backing and stick the material to the chamber walls.
