K75-LND7317/GPS Cadillac+plus Geiger Counterby 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 designedy John Giametti (username: Brohogan) I have been building his DIY Geiger counters for over a year and a halfaving built and sold around 73 of them. All information for this kit is available at the developer’s website. As I haveaid before, this is more of a kit for someone who knows a little bit about electronics but doesn’t have the time oratience to build it, or would rather someone else do all the dirty work. Having been built by me, of course there wille some imperfections, although as minimal as possible. The first one like this took close to a year to complete. It isne of the most advanced kit of all that I have created, with most of the features available.

OPERATION

. LCD DISPLAY: Push the large yellow button to turn on the unit. The LCD backlight display light comes on, andou will see the words:Atomic.Dave K75CADILLAC+plus

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

The second window will show this:345 CPM = 1 uSvRunning at 5.05V

The first line refers to the conversion rate of CPM to uSv/hr for your LND7317 tube (345) this can be changedither in the program sketch, with Arduino, or with the Sony wireless remote control which I will explain later. Theecond line refers to the current voltage that your system is running at. This is a 5 volt system. The 3000mAh 3.7vpo battery is boosted to 5v with a pololu booster. Everytime you start up your GC (geiger counter) it will show you

his so you will always know your current voltage.The third window will look something like this:

Log file:GPSLOG17.csv

This is the confirmation that the SD card is inserted in and it is currently available for writing data logs. Theumber is the log number. You can set how manytimes per minute or per hour you can write to the card automat-ally. There is also a button just above the Backlight switch on the top left that is used to write whatever data is onhe screen to the SD card. Information such as CPM, uSv/hr, battery votage, GPS coordinates, date and time areecorded. If the SD card is not inser ted you will get an error message like this:

CARD!On the first line is the current CPM and its corresponding uSv/hr to the right of it. The s econd line is the default

ate and time which will always be this when you start up as the GPS has not synced with a satellite yet. (signifiedy a solid red LED at the very top of the GC) Once the GPS syncs, the LED will blink, and the date and time willpdate to the current one. However, you will have to make sure your time zone is right (which can be adjusted inhe sketch, or with the remote) the clock is a 24 hour clock.

CPM 24 0.0711/21/12 22:36

. LEDS: Right away, you will hear the beeping of the piezo as your LND7317 GM tube picks up radiation events.here are two LEDs below the LCD. The right one is RED for the Alarm which will only light up when a set alarm

hreshold is reached. The piezo for the alarm has a mute switch allowing you to have a LED only s ilient alarm. Theeft LED is BLUE which is for radiation events and coincides with the beeping piezo which can be muted with the

mute switch.

. SWITCHES, SLOTS, LEDS, BUTTONS, PORTS, DIALS: A. Starting on the left topside of the GC is the LCD contrast dial used for controlling the contrast of the LCD

om time to time it may or may not need to adjusted with a small screwdriver.B. Next is the SD Card slot. Please take speci al care when inserting and removing the card. Once you have it

n the slot, with the very tip of your thumb, push the SD card into the s lot until you feel it click into place. Use theame positition of the Thumb to release it. Once you take out the SD Card, use the included SD card adapter andlug it into your mac or PC. There will be a .csv file that is compatible with Microsoft excel. Open the file with Excel,nd you will see all the information listed. The button on top marked SDLOG is used to write to the card. Push it,nd the display will say LOGGED!

C. INPUT Next down, left side, is the Mini USB FTDIort for programming in Arduino. When uploading any newhanges to the program sketch, you will need to turn off the

GPS in order to do that as they share the same serial port.he Switch for the GPS is located on the face on the farght. Once the edited sketch is uploaded you can turn the

GPS back on.D. CHARGE Below that is the USB charge/power

witch. This is a toggle switch. When the USB is plugged in,witch up will allow you to power the unit and bypass theattery (yellow button power off the unit) switch down, thenit goes into charge mode (also yellow button power off)here is a tin y RED LED on the lower left side of the GC

hat is the charge status. When the battery is fully charged, the light goes out.E. GPS - On the very top center of the GC is the GPS status LED. Blinking when synced, and solid when not.

he Antenna and GPS is just below it inside. It syncs pretty easily indoors. Below that is the wireless remote IR.When using the remote, point it to that location. Sometimes if it does not sync, you may need to get outside or ifou are underground you may not sync at all. As soon as synced, the display will alternate between Normal screen

with the CPM and Converted uSv/hr on top line, Date and time on second line, and the GPS screen with the sameop line, but with your current speed and altitude on the second line in either metric or standard.

F. OUTPUT at the bottom right side is the output multi-port used for Geiger Bot (with the included G-Botable), and for Geiger Graph and RAD OSX with the included audio cable. Just plug in the Geiger Bot cable intohis with the 3 conductor plug, and the 4 conductor into your iphone or ipad. It also serves as an mono audio outputor silent listening with headphones.



G. P-SAVE This is a new switch. A power saving option. In the up position, it will turn off the display and the piezoor long period scanning. Only the BLUE LED, the GPS status LED, and the Alarm will work (both LED and Piezo)

H. MICRO SD CARD USE Push the top left most button to send logs to the SD card for recording, or with thewireless remote you can set what intervals it will automatically write to the card- zero mean no logging (See item 3elow in the remote control area). You can take out the SD card at any time, but I would suggest doing so with theower off. After you take it out, insert into the supplied SD card adapter and insert into your mac of pc. Then you canpen up the CSV file with Microsoft excel. There you will see the captured logs with GPS coordinates, time, date,PM, uSv/hr, and unit battery power.

WITCHES AND BUTTONS ON THE FACE. SD LOG - This is used to send all info to the SD card writer.. BACKLIT - Turns on and off the backlight for the LCD display. This saves battery life, and the life of the display.. EVENT - Turns on and off the corresponding click to the blinking BLUE LED above it.. YELLOW POWER BUTTON - Push in for on, and push out for off. Turn this off when charging and when poweringhe unit with the USB.. ALARM - Turns on and off the alarm piezo. It also corresponds to the RED LED above it.. DOSE - This is a momentary switch. Hold it down, and the LCD display will show timed scaler mode for as longs you hold it down. There are two by default it is set for 1 minute and 10 minute averaging and changes as timeoes by. You can adjust these amounts with the remote control. You can also toggle this to be on all the time wherehe display will go back and forth from regular display mode with CPM and uSv/hr and scaler mode.. GPS - Turns on and off the GPS. This is another way to save battery life. And also when programming the unit it isecessary to turn off the GPS, upload the edited sketch, then after turn it back on.

REMOTE CONTROL SYSTE M:It adds some conveniences such as the ability to adjust certain things on the GC without the need to plug into

our PC or mac. All you have to do is push the power button to start. As soon as you do that these options will popp. Use the channel button to move thru each option, and use the volume buttons to move up or down within thoseptions. You can also use the number pad to input numbers rather than using the up down of the volume. After youeach the desired amount you push ENT to enter it into the system.

. SEC DISP PERIOD is the number of seconds before the display refreshes. (5 seconds is a good setting. Display now based on a "running average" like the Geiger Kit.). 1= DOSE MODE ON - Dose Mode shows the running average of CPM & uSv/h on an alternate display thatomes up after 4 display periods have passed. It can also be activated by closing DIP switch #1 on the board. Notehat Dose Mode will only begin to display once 1 minute has passed.. MIN LOGGING is when to write the log data to the MicroSD card (in minutes). Zero means no log. (Since theetting is in minutes, logged results will not be subject to rounding errors.). CPM->uSv RATIO is ratio for the type of GM tube us ed. 175 is the default for the SBM-20 and 100 is for theDN712. 334 for LND7317. Unlike the "default sketch" only one ratio is supported, but now it can be easily changed.ust type in the number, and push ENT to confirm.. ALARM > CPM when the CPM is greater than this value the alarm LED and Piezo will go off. (or only the LED

when the alarm piezo is turned off). ZONE (>12= +) you need to set your time zone because the GPS provides time in UTC format. The time zonean be anything between -12 and +12, but avoid the complexities of entering negative numbers, values between 0nd 12 are considered negative, and above 12, positive. So if your zone is +5 you would set 17.

f for some odd reason the remote does not work, hit the mute button and when the IR OK! shows up on the dis-lay, you are synced, hit the power button then start hitt ing the up down on the channel button. Other options canlso be added if you know how to program in Arduino.

DIY GEIGER COUNTER DEVELOPERS WEBSITE: (this websitethe kit which this geiger counter is based on. At this site you will findany good sources for your unit and many other subjects having to doith Geiger counters and what this unit is capable of)

ARDUINO Software and Serial-USB connection information:ON the cd you will f ind the FTDI driver and Arduino program ver-

on 1. Install both and restart your mac. Copy the Geigerketch folder to the same folder as your Arduino program is andemember where that is as that will be where you go to saveour sketch everytime you make a change to it. There will alsoe a Library folder that will also need to be in the same folder.ust remember that the folder has to be the same exact names the sketch name is. And also within Arduino, you will have too to preferences and show Arduino where your default sketcholder is. The major difference with this unit is that because this the shielded kit, only system version 9 can be used and/or

modified. You cannot upgrade to the newer system software butnly modify and resave the sketch.

ARDUINO SETTINGS:. Open Arduino. Open the saved sketch .ino file, connect your Geiger countero 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.or more info go to website under Software section on the DIY geiger counter website. Or go to Arduino.cc
