+\section{Preface}
+I did some research on available self hosted solutions for Arduino, as of January 2019. I was thinking of using Thingspeak, but they haven't updated their self hosted git repo since 2016. Adafruit.io is the same but 2017\footnote{And uses node.js :/}. Sparkfun closed down their solution.\footnote{Apparently they have no idea what they are doing, and their solution inevitably blew up. Bloated software...} It seems theother data aggregaters are only interested in people giving them data, so they can then sell it, hoard it like wealth, etc... Another solution is necessary.

+\section{Plan}
+Since I've done some data logging with GNUplot before, I've decided to use a flat text file, and csv output. I don't want to deal with MQTT, as this is in a safe LAN (not over WAN), and security is no issue. I also don't want the clients to do any sending. They are stupid, they sit there, and the server is responsible for data collecting. Simple.
+\vspace{0.2in}
+
+What I will do, as I've already started doing, is hosting a web server on the microcontroller, which has amongst other things, sensor data available. The server will pull data from the sensor, and place it into a flat file. GNUplot will run via cron scripts, and the server will host various jpgs. Let's see how this goes.

+\maketitle
+
+\section{Overview}
+
+User spilled tonic water on a laptop, then kept it powered on and continued to use it (this was a mistake. Turning it off, and removing battery / power, letting the liquid dry, is always the first step in a spill). The next morning the laptop would not power on.
+\section{Equipment}
+Laptop is an HP Pavilion 15 CS model. They are fairly new (date codes on micros are from 2018), and retailing around 500-600 dollars as of just before 2019.
+\includegraphics[scale=0.2]{../pics/DSCN1016.JPG}
+\captionof{figure}{HP}
+\section{Disassembly}
+There is no video tutorial on this online, but the steps are: Remove visible screws from the back of the case. Remove rubber feet, and screws beneath them. Pry open case from edges with plastic spudger tool to remove the clips. You must be careful, as the clips and case are fragile. 
+\begin{itemize}
+\item Where to start with the spudger, and also showing the screwholes underneath the rubber feet.
+
+\includegraphics[scale=0.2]{../pics/DSCN1019.JPG}
+\captionof{figure}{Disassembly}
+\item I was able to scratch the case with the plastic spudger. Be careful!
+
+\includegraphics[scale=0.2]{../pics/DSCN1021.JPG}
+\captionof{figure}{Disassembly}
+\item The case can also crack from pulling it. I didn't pull this hard, but the brittle weak case cracked slightly.
+
+\includegraphics[scale=0.3]{../pics/DSCN1022.JPG}
+\captionof{figure}{Disassembly}
+\item Finally we are in.

+
+\end{itemize}
+
+
+
+
+
+\section{Diagnosis and Repair Log}
+Now we will try to find out what is wrong.
+\begin{itemize}
+\item Right away I can see some visible marring from a likely shorted component. This is where a lot of the soda residue is. 
+
+\includegraphics[scale=0.4]{../pics/DSCN1029.JPG}
+\captionof{figure}{Repair}
+
+\item You can see a layer of cellophane that is in place to protect against spills. Amazing how millions of man hours can go into designing computers, yet a single glass of liquid can destroy one. Something is wrong, here. Crazy.
+
+\includegraphics[scale=0.2]{../pics/DSCN1034.JPG}
+\captionof{figure}{Repair}
+
+\item This switcher, the BACAAB (?) chip is the one that has the failed components. I need a replacement but can't find a data sheet on it. I tried probing at some of the pins to see what was going on, and if I could understand a bit more about this, but due to me probing too close to the pins, (and a few factors, primarily the small package, but no leads, and also the fact I should've used the pads NEAR but not ON the package, I shorted something, and a spark resulted. While I saw a 2.4V signal on a pin, after the short, I was unable to find anything. The battery being removed and replaced did not bring it back.
+
+\includegraphics[scale=0.3]{../pics/DSCN1036.JPG}
+\captionof{figure}{Repair}
+
+\item At this point, this chip, which I am unsure of what it is, appears to have a short and is overheating / shorting. I will need to get a motherboard donor at this point, to further repair the mistakes. As these are new boards, motherboards are not yet cheap enough to make this viable, so I will wait and try again at a later date.
+
+\includegraphics[scale=0.3]{../pics/DSCN1037.JPG}
+\captionof{figure}{Repair}
+
+\item During my troubleshooting, I did find an open resistor, and a capacitor that has visible charring on its solder joint. I'll need to replace these as well. I should've replaced this at first, but without a schematic, I don't know what value the cap should be. The resistor is labeled as 1R0, but reads open. There may also be one other cap that has failed. However, some other components appear OK.

+\section{Preface}
+I did some research on available self hosted solutions for Arduino, as of January 2019. I was thinking of using Thingspeak, but they haven't updated their self hosted git repo since 2016. Adafruit.io is the same but 2017\footnote{And uses node.js :/}. Sparkfun closed down their solution.\footnote{Apparently they have no idea what they are doing, and their solution inevitably blew up. Bloated software...} It seems theother data aggregaters are only interested in people giving them data, so they can then sell it, hoard it like wealth, etc... Another solution is necessary.

+\section{Plan}
+Since I've done some data logging with GNUplot before, I've decided to use a flat text file, and csv output. I don't want to deal with MQTT, as this is in a safe LAN (not over WAN), and security is no issue. I also don't want the clients to do any sending. They are stupid, they sit there, and the server is responsible for data collecting. Simple.
+\vspace{0.2in}
+
+What I will do, as I've already started doing, is hosting a web server on the microcontroller, which has amongst other things, sensor data available. The server will pull data from the sensor, and place it into a flat file. GNUplot will run via cron scripts, and the server will host various jpgs. Let's see how this goes.
+
+
+\section{Implementation}
+\textbf{Ingredients}
+\begin{itemize}
+\item SBC (Beaglebone, Rpi)
+\item Network Connected Sensors
+  \item Time

+\item install foscam in bay three, facing bay 4, to outside of bay 4. Get it higher up this time. I don't like leaving a cable out there, but I don't see doing conduit at this time...? Or should I do conduit... Maybe if it's feasible? Need conduit mounts... and hardware... edit: will need bolts, good drill bit, and nuts, to fasten camera. it's going to have to hang under top of container, or on top. use electric line powered drill - big ladder
+  \item put axis in bay three, possibly outlet in wall, clean up the camera, it's a bit messy
+\item new outlet upstairs behind server. Do this after 3pm. NOT PRIORITY
+\item take inventory of parts purchased, and discuss getting cable for door locks (will need to send email if we don't have cable already)

+\begin{document}
+
+\maketitle
+
+\textbf{Todo}
+
+
+
+TODAYS LIST:
+\begin{itemize} 
+\item fix bay 3 camera angle. (orange ladder / laptop), and mount case (screws)
+\item install 6 inch cable on bay 1 camera (orange ladder)
+
+\item install foscam in bay three, facing bay 4, to outside of bay 4. Get it higher up this time. I don't like leaving a cable out there, but I don't see doing conduit at this time...? Or should I do conduit... Maybe if it's feasible? Need conduit mounts... and hardware... edit: will need bolts, good drill bit, and nuts, to fasten camera. it's going to have to hang under top of container, or on top. use electric line powered drill - big ladder
+  \item put axis in bay three, possibly outlet in wall, clean up the camera, it's a bit messy
+\item new outlet upstairs behind server. Do this after 3pm. NOT PRIORITY
+\item take inventory of parts purchased, and discuss getting cable for door locks (will need to send email if we don't have cable already)
+
+ 
+\end{itemize}
+MAIN LIST: 
+
+\begin{itemize}
+\item Move Bay 4 modector to outside wall, or maybe just closer to wall will be good enough, facing the walkway (I'd like to have it out of view).
+\item Install other one camera that are remaining fro previous work. Needs sheathing.
+\item door access controls, research and buy parts
+\item rfid, research and have them buy parts
+\item two new cameras outside. Need wiring first, then have them buy cameras and emclosures.
+\item Cameras to watch tank install project waiting to hear back from jbemiller
+\item need cable covers for bay 2 axis cam, and box, or a POE adapter
+\item adjust front door camera down
+\item Modectors in other bays, 1, 2, 3 (two in 3)
+\item Consider modectors for outside, near cameras later. They will just be an alarm, perhaps on a camera as mocord, but not nodect or modect. Otherwise, they will be on their own section as an alarm.
+  
+\item Map install somewhere (where?)
+\item check existing doors for lock and rfid brand
+\item dashcams for trucks?
+\item Build outdoor enclosure - on hold. May use for motion dector
+\item Cable covers for bay 2 camera
+\item discuss camera in office first floor, is that wanted on front door? (first do rfid and door access controls)
+\item get power strip to replace one I personally brought for bay 4.   
+\item buy surge protectorss = ethernet, microcenter, for two spots, after server, and after bay 2
+\item commtank needs poe adapters for cameras. needs 1 at the moment
+\item buy hammond boxes for outdoor wiring, waterproof. need to hold wires, maybe motion detector...

+Need to find a chip for battery charging. Some sheets have been saved. I looked at TI primarily. Though considered one AD/LTC. BQ2954 is out of the question as its too complex in its application circuit. THe BQ2000 is a 8 pin DIP and seems like a good start. That will cover nicad/nimh, and lithium batteries.
+
+Though the BQ2000 is a bit of a mess as well. Data sheet has a complex circuit. There is a simpler one here:

+https://electronics.stackexchange.com/questions/95970/how-to-use-battery-charge-controller-bq2002n

+This chip: stc4054, is extremely simple. Limited to 1 lithium cell (so only 4.2 volts max) but application circuit is lean, and it has a shutdown pin, so you can turn off the charger. Price is the cheapest as well, at 1.50 for 1.
+
+That looks hopeful. Why not multiple?
+Need to remember to be careful of 4.1 lithium batteries. Most chargers are 4.2, and its easy to forget that there is a difference.
+
+MCP73826 is another reasonable option. Slightly more complex, but not by much.
+RT9526A is also simple. Let's start with the st chip.
+
+Looks like the voltage on that pin should be between 1.2 and 2.4 in order to turn it off. Below 1.2 it is on, and monitoring current. Above 1.2 but below 2.4 it is off. above 2.4 it's putting 35ua into the battery. I think.
+
+Also like the LTC1734, which is lithium / nicad. But expensive at 3-4 dollars. Don't see any lead acid battery chargers on digi that aren't being obsoleted. There's not one. I did see some on manufacturer's pages though. Just not here.
+
+There is one microchip one (lead acid) based on a pic. App circuit is complex.
+AN1015 is the app note.
+
+So need a lead, and nicd charger still.
+
+Tomorrow I'd like to look at maxim. I see this:
+
+https://www.maximintegrated.com/en/products/power/battery-management/MAX1772.html
+But the application circuit is too much for what I want to deal with.
+Seems lead acid battery chargers are not as common as they must've been before.
+
+Onsemi is only lithium batteries.
+
+Mouser has only universal chargers, no lead. But universal includes lead.

+lt1510 would work for nicad. data sheet figure 6 has a circuit for nicad.
+

+lt1513 does the three main types: nicd,li-ion,lead

+I'd recommend just float charging. It takes only a little longer

+ charge current to about 0.1 C (so 2 A for a 20 AH battery). The
+ easiest way to do this is a constant current/ constant voltage
+ power supply. Set the current limit to the desired charge current,
+ and the voltage to the float voltage (13.8 V adjusted for
+ temperature if needed). The voltage on the battery will slowly
+ increase over time until it reaches ~13.8 V, then the current will
+ slowly drop over time until it reaches nearly zero. At that point,

+Which is what I did with my solar battery charger, and it worked well. So I suppose there is no need for anything more than a vreg for lead batteries. This time I will go to the recommended 13.8 instead of what I had before (around 12) and I will do the same trickle charge method. Simple. Done.
+
+May use 1512 instead. \$5 in 150 quantity. Hm...
+\$10 in single.
+That would cover lead, nicad.
+Will need jumpers on R1 and R2 depending on what battery type. According to data sheet, li-ion the divider is a float voltage. In nicd, it is a top limit.
+
+OK, i've decided:
+
+\subsection{Part Selection Summary}
+
+LT1512, and STC4054.
+For starters, I will use stc as lithium and lt as nicad / lead.
+
+this will avoid the worry of jumpers, and what not. Later I can be flexible.
+
+Now onto other parts. I need some way to monitor the current, and of course a voltage tap.
+
+Where to put current sense? I think before the battery.
+
+I should put some jumpers in, so I can isolate everything though. I dont' want to mix circuits at the start. So isolate the charger from the op amp and sense, at first.
+
+Let's go with the basic differential op amp in microchip an1332. I need a vreg supply (linear) at 15.5 volts, for the op amp, so it's above the lead battery voltage. Simplest two switchers I see are lm2577 or the mk3608. The mk is easier to use.
+
+With that we have:
+\begin{itemize}
+\item Battery charger x 2
+\item voltage monitor x 2
+\item current monitor x 2
+\item ethernet (using off the shelf enc modules for now, but maybe
+  on board later).
+\item microcontroller (nano)
+\item temperature monitor (something like max6675 looks nice. can put on board, without difficulty).
+  \item additional taps into adc, and some op amps and current shunts not populated to be used as extra current - voltage converters. At least two. Put on modular schematic.
+  
+  \end{itemize}
+I also want a general current and voltage monitor. I want
+to be able to watch the load on a battery, and record that as well...
+Perhaps that will be separate. I might want to grab some off the shelf
+current / voltage monitoring stuff, or just throw a few op amps with breakouts on the board.
+
+Let's build.
+
+Keep all schematics modular!
