HIRO Geiger Counter K52-LND7317by Atomic.dave Atomic.Dave@yahoo.com

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, EVENT, LIGHT, ALARM, switches UP. The LCD backlight display lightomes on, you will hear beeping, and you see the words:

ATOMIC DAVE HIRO

LND7317 ver.8.1

This customized first welcome window can easily be changed if you want, by doing a little programmingn Arduino. Refer to the DIY site for directions at the SOFTWARE section.

The second window will show something like this:360 CPM to uSv

Running at 5.36V

The first line refers to the conversion rate of CPM to uSv/hr for your LND7317 tube (360) this can behanged in the program sketch, with Arduino, but it is set so no change is necessary. The second line referso the current voltage that your system is running at. This is a 5 volt system. The (4) 2600mAh 1.2v nimh bat-eries are boosted to 5v with a pololu Step up/down booster. Everytime you start up your GC (geiger counter)

will show you this so you 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 CPMepresentation. 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.

EDSRight 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 bemuted with the mute switch just below it. The RED comes on only when the set threshold is reached. On theower right side of the unit is just above the MINI USB FTDI port is a GREEN LED which is a system statusght 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.

SWITCHESON the face of the unit is first the Yellow power button, (IN for on, and OUT for off), then the event piezon/off switch, the Green Display mode button described below, the alarm piezo on/off, then the backlight onff switch.

BLACK MENU MODE BUTTON1. When you first turn on the unit, the third window will prompt you to set the Alarm. If you have not set it

et, it will say Alarm OFF. However if you hold the mode button down the alarm set amount will climb in incre-ments of 10 cpm till it gets to 100, then it climbs in sets of 50 until it reaches a max of 600 cpm, until you leto, and once you let go, that is what the alarm threshold will be until you reset it. As long as you don't reset, that is the amount it will remain at. I have preset the alarm to 150 CPM.

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 youress it for the first time it will start the timer process where it will give you average counts in a 1 minute and0 minute period. Until it reaches 1 minute or 10 minutes it will show current total counts. After it reacheshose 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 MULTIPORTAt the bottom left side is the output multi-port used for Safecast (with the included Safecast cable), and forGeiger Graph and RAD OSX (with the optional USB/FTDI cable) Just plug in the Safecast cable in with the 3onductor plug, and the 4 conductor into your iphone or ipad. Or plug the optional FTDI 3.5mm to USB cablento the port, and into a USB on your mac or PC, then follow instructions to run those programs. It alsoerves as an mono audio output for silent listening with headphones. I have also supplied you with a audioable that you can use to plug your unit into your mac or pcs mic input, then you can run audio based geigerounter data logging software such as RAD OSX. However the prefered method is to use the optional cable

hat is listed below. Google FTDI/TTL-232R-3V3-AJ.

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 ashat will be where you go to save your sketch everytime you make a change to it. There will also be a Libraryolder that will also need to be in the same folder. Just remember that the folder has to be the same exactame 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, uSvnd geiger counter voltage data coming up once per minute.

For more info go to website under Software section on the DIY geiger counter website. Or go to Arduino.cc

Safecast SUGGESTED SETTINGS: (You will probably have to play with it to get it just right- and I used touse Geiger Bot, but it seems that Safecast is more stable and works everytime.)https://itunes.apple.com/us/app/safecast/id571167450?mt=8

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 theFTDI/TTL USB cable below)http://www.blackcatsystems.com/GM/download.html

GEIGER GRAPH FOR PC NETWORKS:http://www.imagesco.com/geiger/geiger-graph.htmlcost is around $60. Use the Optional FTDI 3.5mm 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 batteries fully before first use)

A. You can power the Geiger in a couple different ways1. With internal nimh batteries2. With USB cable plugged into data port on RIGHT side of geiger then plugged into:

a. Computer or laptop USB

b. 5V USB Wall charger block (not 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 wayfor 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 itwould be to use the USB cable plugged in r ight FTDI port and power OFF.

POWER and OTHER SYSTEM ITEMS:A. (4) Tenergy Nimh AA battery - 1.2v 2600mAhhttp://www.batteryjunction.com/1po20aaba.html Full recharge in 3-7 hours, provides approximately 25-40 hour constant use of geiger counter Remove the batteries by unscrewing the battery compartment plate.

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.

http://www.newageenclosures.com/files/784114_r5_2.pdf

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 pan

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.
