Sentinel Geiger Counter K46-LND7317by Atomic.dave [email protected]
This is a one of a kind custom hand-made Geiger Counter built by Atomic.Dave. It is based on a kit designed by John
Giametti (username: Brohogan) All information for this kit is available at the developers website. As I have said before, this
s more of a kit for someone who knows a little bit about electronics but doesnt have the time or patience to build it, or
would rather someone else do all the dirty work. Having been built by me, of course there will be some imperfections, al-
hough as minimal as possible.

OPERATION
. LCD DISPLAY: Flip power, light and sound (mute) switch To the RIGHT (on). The LCD backlight displayght comes on, and you will see the words:
Atomic.Dave 46.8SENTINEL LND7317
This customized first welcome window can easily be changed if you want, by doing a little programming
n Arduino. Refer to the DIY site for directions at the SOFTWARE section.
The second window will show something like this:360 CPM to uSvRunning at 5.05V
The first line refers to the conversion rate of CPM to uSv/hr for your LND7317 tube (360) this can be
hanged in the program sketch, with Arduino, but it is set so no change is necessary. The second line refers
o the current voltage that your system is running at. This is a 5 volt system. The 2600mAh 3.7v lipo battery is
oosted to 5v with a pololu booster. Everytime you start up your GC (geiger counter) it will show you this soou will always know your current voltage.
After that, the third window will look something like this:CPM 48 || ||| ||| ||uSv/hr 0.13
On the first line is the current CPM and to the right of it is a graphical simulation of by the second CPM
epresentation. On the second line is the converted uSv/hr. (48 divided by 360)if it was a different geigerube such as the SBM-20, then the conversion rate would be 175 or 48 divided by 175 which would be 0.27.
EDS
Right away, you will hear the beeping of the piezo as your LND7317 GM tube picks up radiation events.
There are three LEDs. The BLUE is for radiation events and coincides with the beeping piezo which can be
muted with the mute switch just below it. The RED comes on only when the set threshold is reached. On the
ower right side of the unit is just above the MINI USB FTDI port is a GREEN LED which is a system status
ght that comes on when starting up, and when sending data back and forth to either your PC. If the greenght ever freezes up, just restart the GC, and it will reset itself.
SWITCHES
ON the face of the unit of course is first the power switch, (right for on, and left for off), then the backlight
n/off BELOW that is the Mode switch described below, and below that are the two mute switches for the
larm and event piezos.
WHITE MENU MODE BUTTON
1. When you first turn on the unit, it will prompt you to set the Alarm. If you have not set it yet, it will say
Alarm OFF. However if you hold the mode button down the alarm set amount will climb in increments of 10
pm till it gets to 100, then it climbs in sets of 50 until it reaches a max of 600 cpm, until you let go, and once
ou let go, that is what the alarm threshold will be until you reset it. As long as you don't reset it, that is the
mount it will remain at.
2. The first display that comes up is the current CPM and below it is the level of uSv/hr. To the right of theCPM is a bar graphic representative of the level of Radiation occuring by the second. The CPM and uSv por-
on is updated every 4 seconds.
3. Press the mode button and a new display will come up. It is like a stopwatch and as soon as you
ress it for the first time it will start the timer process where it will give you average counts in a 1 minute and
0 minute period. Until it reaches 1 minute or 10 minutes it will show current total counts. After it reaches
hose points it will show the uSv conversion on the right column.
4. Press the mode button again and it will go back to the first menu.
.5MM MULTIPORT
inally at the bottom right side is the output multi-port used for Geiger Bot (with the included G-Bot cable),
nd for Geiger Graph and RAD OSX (with the optional USB/FTDI cable) Just plug in the Geiger Bot cable
nto this with the 3 conductor plug, and the 4 conductor into your iphone or ipad. Or plug the FTDI 3.5mm to
USB cable into the port, and into a USB on your mac or PC, then follow instructions to run those programs. It
lso serves as an mono audio output for silent listening with headphones.

ARDUINO Software and Serial-USB connection information:
ON the cd you will find the FTDI driver and Arduino program version 1. Install both and restart your mac.
Copy the Geiger Sketch folder to the same folder as your Arduino program is and remember where that is as
hat will be where you go to save your sketch everytime you make a change to it. There will also be a Library
older that will also need to be in the same folder. Just remember that the folder has to be the same exact
ame as the sketch name is. And also within Arduino, you will have to go to preferences and show Arduino
where your default sketch folder is.
ARDUINO SETTINGS:
. Open Arduino
. Open the saved sketch .ino file, connect your Geiger counter to the USB with power switch off.
. Verify the file by clicking the little check mark icon.
. Click TOOLS, and Select Board type as Arduino UNO, and select serial port as the top tty choice.
. Click Serial Monitor (top right looking glass icon). Set Baud rate to 9600 and you should see the CPM, uSv
nd geiger counter voltage data coming up once per minute.
or more info go to website under Software section on the DIY geiger counter website. Or go to Arduino.cc
GEIGER BOT SUGGESTED SETTINGS: (You will probably have to play with it to get it just right)https://sites.google.com/site/geigerbot/
RAD OSX free data logging for macs: (although you can use the included 3.5mm male to male 3 conduc-or to 3 conductor audio cable from the multiport to your PC or Macs MIC input, it works best with the
FTDI/TTL USB cable below)http://www.blackcatsystems.com/GM/download.html
GEIGER GRAPH FOR PC NETWORKS:
http://www.imagesco.com/geiger/geiger-graph.html
cost is around $60. Use the Optional FTDI3.5mm to USB cable) This is a PC only software. To purchasehe optional cable go to:www.mouser.com, and do a search for: FTDI/TTL-232R-3V3-AJ
HARDWARE
. DIY Geiger counter kit V4.0 by Brohogan
http://www.sites.google.com/site/diygeigercounter/
. LND 7317 Geiger Muller Tube
. Power System by Tenergy and Pololu (please charge the unit for minimum 3 hours before use)
A. You can power the Geiger in a couple different ways
1. With internal Lipo battery
2. While charging Lipo battery with USB plugged into LEFT side of geiger with power switch ON.
3. With USB cable plugged into data port on RIGHT side of geiger then plugged into:
a. Computer or laptop USB
b. Wall charger block (included)
c. Standard 5v USB Cigarette adapter (not included)
d. To power and operate the unit this way make sure POWER SWITCH IS IN OFF POSITION
- Its ok to have switch the on for a little while, but DAMAGE MIGHT OCCUR if left this way
for long periods- best bet is NOT to do this.
e. For long usage of geiger counter (constant on for long periods) the preferred way to power it
would be to use the internal LIPO until it runs out (approximately 25 hours with light on, and
40 hours with light off) or with USB cable plugged in right FTDI port and power OFF.

ND-7317 GEIGER MULLER TUBE
nstalled inside this nicely planned out kit is a PANCAKE LND 7317 which senses Alpha, Beta and Gamma. The pancake tube is mounted to
ase by a solid copper bracket, with a galvanized 1/8" mesh for protection and silicon feet. I will be Including and shipping the Geiger Counte
ide a Pelican 1060 atmospheric controlled case to protect the pancake from high altitude and pressure implosion during shipping.

PELICAN 1060 CARRYING CASE
Always, store your geiger counter in this case with the latch securely fastened. This will keep the pancake tube safe and free from atmospherressure. Especially if you plan on shipping it somewhere in high altitude. I have personally never had or seen a damaged pancake tube from
ituation, but I have heard many horror stories of people even driving with their geiger counters up a very tall mountain, and seeing their panc
mplode. As I cannot say that this will happen, I just made the choice to sell and include this case with the unit just as a precaution.
