+  \section{Attiny Solar Energy Harvest Tests}}
+
+I have the following:
+\begin{itemize}
+\item Solar panels
+\item Attiny 10
+\end{itemize}
+To this list, I will add a supercap, and an energy harvesting IC. The goal being to load the super cap during the day, and to run 24/7. I will need an exceptionally low power micro. The super cap will need to be about 3.3V or 5V.
+
+\subsection{Micro Considerations}
+The Arduino Atmega328P is not an option. I'm looking to have a current draw of only 1mA max, (ideally 500uA) when active. Moteino is also not an option for this. Those are made for batteries. I want to be battery free. A super cap, however can be used to store energy. I'll get to that shortly.
+
+For micros, I have some Attiny10 on hand, and these have a reasonably low power pull in active mode. Let's build those up first. What will the micro do? No idea. I haven't a clue.
+
+\subsection{Energy Storage}
+I don't want a battery. Let's go with a super cap. The solar panels will only be active some of the time, so I will want to harvest energy with some kind of IC into the cap when the sun is out.\footnote{Reference: www.analog.com/media/en/technical-documentation/technical-articles/solarenergyharvesting.pdf is a start. I'll need to do more research.}

+
+Then I can 3D print a box, throw some LEDs in there, and get a hardware interface for anything from my distro.
+\subsection{Setup}
+First off, I installed the stable uLisp from ulisp.com (AVR version 3.4). 
+\subsubsection{Trouble with interfacing directly to ttyACM0 / ttyUSB0}
+The Arduino Uno uses an FTDI USB to Serial chip. It also has more than just RX/TX connected (I think). This means that when you echo "something" to
+arduino, this command will open the serial connection, send the command, then close the command and possibly reset the board via one of the
+UART reset pins (DTS perhaps). This won't work. First thing to do, get an FTDI board, and connect it to the computer, the connect
+it to digital pins 0,1 (for UART). Then test sending a command. This works. This will be the final setup. Computer -> FTDI -> Arduino.
+
+
+It should be possible to get it to work without the FTDI chip, but not without some debugging. Have at it, if you wish.

+should be simple.

+
+\subsubsection{Troubleshooting Code}
+The first thing you will want to do is prove that you can echo or cat "code" > /dev/ARDUINO.
+This code works:
+\begin{verbatim}
+(defun b (&optional x)
+  (pinmode 13 :output)
+  (digitalwrite 13 x)
+  (delay 1000)
+  (b (not x)))
+(b)
+\end{verbatim}
+Save it as a text file, then cat the file into /dev/ttyUSB0 or /dev/ARDUINO. Problem is, that code runs indefinitely. You can't tell it to do anything else. Hit the reset button to restart the Uno back to square one. So instead, you want a loop that runs and then stops. Here's one of those:
+\begin{verbatim}
+(defun b ()
+  (pinmode 13 :output)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200))
+(b)

+This works. Save it as a .dat or .txt (whatever) and cat file.txt > /dev/ARDUINO. It will run a few times, then stop. You can echo it again, if you wish.
+There, now we have an interface, and we have proven we can switch an IO high. With a couple of functions, it's trivial to go from there.\footnote{i.e. have one function set IO high for a given pin. Have one function set IO low. Have one function blink IO some amount of times. This can be used for counters or shift registers.}

+  \section{UserSpace IO via uLisp and Arduino Uno}}
+Overview: Goal is to get an easy way to echo "command" > /dev/ARDUINO from GnuLinux userspace.
+
+Then I can 3D print a box, throw some LEDs in there, and get a hardware interface for anything from my distro. 
+
+\subsection{Setup} 
+First off, I installed the stable uLisp from ulisp.com (AVR version 3.4 in 2020/12). 
+
+\subsubsection{Trouble with interfacing directly to 
+ttyACM0 / ttyUSB0} The Arduino Uno uses an FTDI USB to Serial chip. It also has more than just RX/TX connected (I think). This means 
+that when you echo "something" to arduino, this command will open the serial connection, send the command, then close the command and 
+possibly reset the board via one of the UART reset pins (DTS perhaps). This won't work. First thing to do, get an FTDI board, and 
+connect it to the computer, the connect it to digital pins 0,1 (for UART). Then test sending a command. This works. This will be the 
+final setup. Computer -> FTDI -> Arduino.
+
+
+It should be possible to get it to work without the FTDI chip, but not without some debugging. Have at it, if you wish. I don't have 
+time to troubleshoot this now. I tried a few things (exec 3<>, and the stty) neither worked. You could also use Python, but then that's 
+more dependencies. Bad idea. This should be simple.

+
+\subsubsection{Troubleshooting Code}
+The first thing you will want to do is prove that you can echo or cat "code" > /dev/ARDUINO.
+This code works:
+\begin{verbatim}
+(defun b (&optional x)
+  (pinmode 13 :output)
+  (digitalwrite 13 x)
+  (delay 1000)
+  (b (not x)))
+(b) 
+\end{verbatim} 
+
+Save it as a text file, then cat the file into /dev/ttyUSB0 or /dev/ARDUINO. Problem is, the code runs 
+indefinitely. You can't tell it to do anything else. Hit the reset button to restart the Uno back to square one. So instead, you want a 
+function that runs and then stops. Here's one of those: 
+
+\begin{verbatim} (defun b ()
+  (pinmode 13 :output)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200))
+(b)
+\end{verbatim} 
+This works. Save it as a .dat or .txt (whatever) and cat file.txt > /dev/ARDUINO. It will blink a few times, then 
+stop. You can cat it again, if you wish. There, now we have an interface, and we have proven we can switch an IO high/low. With a couple 
+of functions, it's trivial to build an interface.\footnote{i.e. have one function set IO high for a given pin. Have one function set IO low. 
+Have one function blink IO some amount of times. This can be used for counters or shift registers, or in the former, just controlling GPIO.}
+
+
+Tip: When building code, copy and paste into the Arduino Serial Monitor first. This way, if there's an error, it will tell you what's 
+wrong. After you've tested the code, then you can put it in a text file. As we are keeping this simple, we don't have logging setup, or 
+anything else. This is meant to be for basic IO from user space, not C compiled programs. Think lightweight. Fast. Fun.
+
+\subsection{An interface for basic GPIO}
+Now, let's build an API/interface so that we can flip some IO, and perhaps increment as mentioned.

+Overview: Goal is to get an easy way to echo "command" \textgreater
+
+/dev/ARDUINO from GnuLinux userspace.
+
+Then I can 3D print a box, throw some LEDs in there, and get a hardware interface for anything from my distro.
+\\
+
+
+\subsection{Setup} 
+First off, I installed the stable uLisp from ulisp.com (AVR version 3.4 in 2020/12). \footnote{It's a sketch. It installs from Arduino IDE (must be reasonably recent, so 1.8 from Arduino.com works, but not Beowulf/Buster's 1.0 Arduino).}
+
+\subsubsection{Trouble with interfacing directly to 
+ttyACM0} The Arduino Uno uses an FTDI USB to Serial chip. It also has more than just RX/TX connected (I think). This means 
+that when you echo "something" to arduino, this command will open the serial connection, send the command, then close the command and 
+possibly reset the board via one of the UART reset pins (DTS perhaps). This won't work. First thing to do, get an FTDI board, and 
+connect it to the computer, the connect it to digital pins 0,1 (for UART). Then test sending a command. This works. This will be the 
+final setup. Computer -\textgreater FTDI -\textgreater Arduino.
+
+
+It should be possible to get it to work without the FTDI chip, but not without some debugging. Have at it, if you wish. I don't have 
+time to troubleshoot this now. I tried a few things (exec 3\textless \textgreater, and the stty) neither worked. You could also use Python, but then that's 
+more dependencies. Bad idea. This should be simple.

+
+https://stackoverflow.com/questions/3918032/bash-serial-i-o-and-arduino
+
+\subsubsection{Troubleshooting Code}
+The first thing you will want to do is prove that you can echo or cat "code" \textgreater /dev/ARDUINO.
+This code works:
+\begin{verbatim}
+(defun b (&optional x)
+  (pinmode 13 :output)
+  (digitalwrite 13 x)
+  (delay 1000)
+  (b (not x)))
+(b) 
+\end{verbatim} 
+
+Save it as a text file, then cat the file into /dev/ttyUSB0 or /dev/ARDUINO. Problem is, the code runs 
+indefinitely. You can't tell it to do anything else. Hit the reset button to restart the Uno back to square one. So instead, you want a 
+function that runs and then stops. Here's one of those: 
+
+\begin{verbatim} (defun b ()
+  (pinmode 13 :output)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200))
+(b)
+\end{verbatim} 
+This works. Save it as a .dat or .txt (whatever) and cat file.txt \textgreater /dev/ARDUINO. It will blink a few times, then 
+stop. You can cat it again, if you wish. There, now we have an interface, and we have proven we can switch an IO high/low. With a couple 
+of functions, it's trivial to build an interface.\footnote{i.e. have one function set IO high for a given pin. Have one function set IO low. 
+Have one function blink IO some amount of times. This can be used for counters or shift registers, or in the former, just controlling GPIO.}
+
+
+Tip: When building code, copy and paste into the Arduino Serial Monitor first. This way, if there's an error, it will tell you what's 
+wrong. After you've tested the code, then you can put it in a text file. As we are keeping this simple, we don't have logging setup, or 
+anything else. This is meant to be for basic IO from user space, not C compiled programs. Think lightweight. Fast. Fun.
+
+\subsection{An interface for basic GPIO}
+Now, let's build an API/interface so that we can flip some IO, and perhaps increment as mentioned.
+
+\begin{verbatim}
+ let's ask this: what do I want to accomplish? 
+
+ answer: I want to be able to flash leds from user space. possibly increment a counter, but
+ that's later. for now, just flash leds.
+
+ solution: build box / board for uno. connect everything up. build initialization program
+ (that will enable outputs as high)
+ Then find a way to send commands from gnulinux. let's begin.
+
+1. build initialization program
+2. create enclosure, and wire up leds
+3. run program live from gnuLinux.
+
+\end{verbatim}
+

+  \section{UserSpace IO via uLisp and Arduino Uno}}
+Overview: Goal is to get an easy way to echo "command" \textgreater
+
+/dev/ARDUINO from GnuLinux userspace.
+
+Then I can 3D print a box, throw some LEDs in there, and get a hardware interface for anything from my distro.
+\\
+
+
+\subsection{Setup} 
+First off, I installed the stable uLisp from ulisp.com (AVR version 3.4 in 2020/12). \footnote{It's a sketch. It installs from Arduino IDE (must be reasonably recent, so 1.8 from Arduino.com works, but not Beowulf/Buster's 1.0 Arduino).}
+
+\subsubsection{Trouble with interfacing directly to 
+ttyACM0} The Arduino Uno uses an FTDI USB to Serial chip. It also has more than just RX/TX connected (I think). This means 
+that when you echo "something" to arduino, this command will open the serial connection, send the command, then close the command and 
+possibly reset the board via one of the UART reset pins (DTS perhaps). This won't work. First thing to do, get an FTDI board, and 
+connect it to the computer, the connect it to digital pins 0,1 (for UART). Then test sending a command. This works. This will be the 
+final setup. Computer -\textgreater FTDI -\textgreater Arduino.
+
+
+It should be possible to get it to work without the FTDI chip, but not without some debugging. Have at it, if you wish. I don't have 
+time to troubleshoot this now. I tried a few things (exec 3\textless \textgreater, and the stty) neither worked. You could also use Python, but then that's 
+more dependencies. Bad idea. This should be simple.

+
+\subsubsection{Troubleshooting Code}
+The first thing you will want to do is prove that you can echo or cat "code" \textgreater /dev/ARDUINO.
+This code works:
+\begin{verbatim}
+(defun b (&optional x)
+  (pinmode 13 :output)
+  (digitalwrite 13 x)
+  (delay 1000)
+  (b (not x)))
+(b) 
+\end{verbatim} 
+
+Save it as a text file, then cat the file into /dev/ttyUSB0 or /dev/ARDUINO. Problem is, the code runs 
+indefinitely. You can't tell it to do anything else. Hit the reset button to restart the Uno back to square one. So instead, you want a 
+function that runs and then stops. Here's one of those: 
+
+\begin{verbatim} (defun b ()
+  (pinmode 13 :output)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200)
+  (digitalwrite 13 nil)
+  (delay 500)
+  (digitalwrite 13 t)
+  (delay 200))
+(b)
+\end{verbatim} 
+This works. Save it as a .dat or .txt (whatever) and cat file.txt \textgreater /dev/ARDUINO. It will blink a few times, then 
+stop. You can cat it again, if you wish. There, now we have an interface, and we have proven we can switch an IO high/low. With a couple 
+of functions, it's trivial to build an interface.\footnote{i.e. have one function set IO high for a given pin. Have one function set IO low. 
+Have one function blink IO some amount of times. This can be used for counters or shift registers, or in the former, just controlling GPIO.}
+
+
+Tip: When building code, copy and paste into the Arduino Serial Monitor first. This way, if there's an error, it will tell you what's 
+wrong. After you've tested the code, then you can put it in a text file. As we are keeping this simple, we don't have logging setup, or 
+anything else. This is meant to be for basic IO from user space, not C compiled programs. Think lightweight. Fast. Fun.
+
+\subsection{An interface for basic GPIO}
+Now, let's build an API/interface so that we can flip some IO, and perhaps increment as mentioned.
+
+\begin{verbatim}
+ let's ask this: what do I want to accomplish? 
+
+ answer: I want to be able to flash leds from user space.
+ possibly increment a counter, but
+ that's later. for now, just flash leds.
+
+ solution: build box / board for uno. connect everything up.
+ build initialization program
+ (that will enable outputs as high)
+ Then find a way to send commands from gnulinux. let's begin.
+
+1. build initialization program
+2. create enclosure, and wire up leds
+3. run program live from gnuLinux.
