K74-LND7317/GPS Cadillac+plus Geiger Counter by 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) I have been building his DIY Geiger counters for over a year and a half having built and sold around 73 of them. All information for this kit is available at the developer’s website. As I have said before, this is more of a kit for someone who knows a little bit about electronics but doesn’t 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, although as minimal as possible. The first one like this took close to a year to complete. It is one of the most advanced kit of all that I have created, with most of the features available. OPERATION 1. LCD DISPLAY: Push the large yellow button to turn on the unit. The LCD backlight display light comes on, and you will see the words: Atomic.Dave K74 CADILLAC+plus This customized first welcome window can easily be changed if you want, by doing a little programming in Ar- duino. Refer to the DIY site for directions at the SOFTWARE section. The second window will show this: 345 CPM = 1 uSv Running at 5.05V The first line refers to the conversion rate of CPM to uSv/hr for your LND7317 tube (345) this can be changed either in the program sketch, with Arduino, or with the Sony wireless remote control which I will explain later. The second line refers to the current voltage that your system is running at. This is a 5 volt system. The 3000mAh 3.7v lipo battery is boosted to 5v with a pololu booster. Everytime you start up your GC (geiger counter) it will show you this 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. The number is the log number. You can set how manytimes per minute or per hour you can write to the card automat- cally. There is also a button just above the Backlight switch on the top left that is used to write whatever data is on the screen to the SD card. Information such as CPM, uSv/hr, battery votage, GPS coordinates, date and time are recorded. If the SD card is not inserted 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 second line is the default date and time which will always be this when you start up as the GPS has not synced with a satellite yet. (signified by a solid red LED at the very top of the GC) Once the GPS syncs, the LED will blink, and the date and time will update to the current one. However, you will have to make sure your time zone is right (which can be adjusted in the sketch, or with the remote) the clock is a 24 hour clock. CPM 24 0.07 11/21/12 22:36 2. LEDS: Right away, you will hear the beeping of the piezo as your LND7317 GM tube picks up radiation events. There are two LEDs below the LCD. The right one is RED for the Alarm which will only light up when a set alarm threshold is reached. The piezo for the alarm has a mute switch allowing you to have a LED only silient alarm. The left LED is BLUE which is for radiation events and coincides with the beeping piezo which can be muted with the mute switch. 3. SWITCHES, 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 from time to time it may or may not need to adjusted with a small screwdriver. B. Next is the SD Card slot. Please take special care when inserting and removing the card. Once you have it in the slot, with the very tip of your thumb, push the SD card into the slot until you feel it click into place. Use the same positition of the Thumb to release it. Once you take out the SD Card, use the included SD card adapter and plug it into your mac or PC. There will be a .csv file that is compatible with Microsoft excel. Open the file with Excel, and you will see all the information listed. The button on top marked SDLOG is used to write to the card. Push it, and the display will say LOGGED! C. INPUT Next down, is the Mini USB FTDI port for programming in Arduino. When uploading any new changes to the program sketch, you will need to turn off the GPS in order to do that as they share the same serial port. The Switch for the GPS is located on the face on the far right. Once the edited sketch is uploaded you can turn the GPS back on. D. CHARGE Below that is the USB charge/power switch. This is a toggle switch. When the USB is plugged in, switch up will allow you to power the unit and bypass the battery (yellow button power off the unit) switch down, the unit goes into charge mode (also yellow button power off) There is a tiny RED LED on the lower right side of the GC that is the charge status. When the battery is fully charged, the light goes out. E. On the very top on the face of the GC is the GPS status LED. Blinking when synced, and solid when not. The 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.

This customized first welcome window can easily be changed if you want, by doing a little programming in Ar-duino. Refer to the DIY site for directions at the SOFTWARE section.
The second window will show this:345 CPM = 1 uSv Running at 5.05V
The first line refers to the conversion rate of CPM to uSv/hr for your LND7317 tube (345) this can be changedeither in the program sketch, with Arduino, or with the Sony wireless remote control which I will explain later. Thesecond line refers to the current voltage that your system is running at. This is a 5 volt system. The 3000mAh 3.7vlipo battery is boosted to 5v with a pololu booster. Everytime you start up your GC (geiger counter) it will show youthis 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. Thenumber is the log number. You can set how manytimes per minute or per hour you can write to the card automat-cally. There is also a button just above the Backlight switch on the top left that is used to write whatever data is onthe screen to the SD card.

The right one is RED for the Alarm which will only light up when a set alarmthreshold is reached. The piezo for the alarm has a mute switch allowing you to have a LED only silient alarm. Theleft LED is BLUE which is for radiation events and coincides with the beeping piezo which can be muted with themute switch.
3. SWITCHES, 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
from time to time it may or may not need to adjusted with a small screwdriver. B. Next is the SD Card slot. Please take special care
when inserting and removing the card. Once you have it inthe slot, with the very tip of your thumb, push the SD cardinto the slot until you feel it click into place. Use the samepositition of the Thumb to release it. Once you take out theSD Card, use the included SD card adapter and plug it intoyour mac or PC. There will be a .csv file that is compatiblewith Microsoft excel. Open the file with Excel, and you willsee all the information listed. The button on top markedSDLOG is used to write to the card. Push it, and the displaywill say LOGGED!
C. INPUT Next down, is the Mini USB FTDI port forprogramming in Arduino. When uploading any new changesto the program sketch, you will need to turn off the GPS inorder to do that as they share the same serial port. The Switch for the GPS is located on the face on the far right.Once the edited sketch is uploaded you can turn the GPS back on.
D. CHARGE Below that is the USB charge/power switch. This is a toggle switch. When the USB is plugged in,switch up will allow you to power the unit and bypass the battery (yellow button power off the unit) switch down, theunit goes into charge mode (also yellow button power off) There is a tiny RED LED on the lower right side of theGC that is the charge status. When the battery is fully charged, the light goes out.
E. On the very top on the face of the GC is the GPS status LED. Blinking when synced, and solid when not.The 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.
F. OUTPUT at the bottom right side is the output multi-port used for Geiger Bot (with the included G-Botcable), and for Geiger Graph and RAD OSX with the included audio cable. Just plug in the Geiger Bot cable intothis with the 3 conductor plug, and the 4 conductor into your iphone or ipad. It also serves as an mono audio outputfor 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 piezofor long period scanning. Only the BLUE LED, the GPS status LED, and the Alarm will work (both LED and Piezo)
REMOTE CONTROL SYSTEM:It adds some conveniences such as the ability to adjust certain things on the GC without the need to plug into
your PC or mac. All you have to do is push the power button to start. As soon as you do that these options will popup. Use the channel button to move thru each option, and use the volume buttons to move up or down within thoseoptions. You can also use the number pad to input numbers rather than using the up down of the volume. After youreach the desired amount you push ENT to enter it into the system.
1. SEC DISP PERIOD is the number of seconds before the display refreshes. (5 seconds is a good setting. Displayis now based on a "running average" like the Geiger Kit.)2. 1= DOSE MODE ON - Dose Mode shows the running average of CPM & uSv/h on an alternate display thatcomes up after 4 display periods have passed. It can also be activated by closing DIP switch #1 on the board. Notethat Dose Mode will only begin to display once 1 minute has passed.3. MIN LOGGING is when to write the log data to the MicroSD card (in minutes). Zero means no log. (Since thesetting is in minutes, logged results will not be subject to rounding errors.)4. CPM->uSv RATIO is ratio for the type of GM tube used. 175 is the default for the SBM-20 and 100 is for theLDN712. 334 for LND7317. Unlike the "default sketch" only one ratio is supported, but now it can be easily changed.Just type in the number, and push ENT to confirm.5. ALARM > CPM when the CPM is greater than this value the alarm LED and Piezo will go off. (or only the LEDwhen the alarm piezo is turned off) 6. ZONE (>12= +) you need to set your time zone because the GPS provides time in UTC format. The time zonecan be anything between -12 and +12, but avoid the complexities of entering negative numbers, values between 0and 12 are considered negative, and above 12, positive. So if your zone is +5 you would set 17.If for some odd reason the remote does not work, hit the mute button and when the IR OK! shows up on the dis-play, you are synced, hit the power button then start hitting the up down on the channel button. Other options canalso be added if you know how to program in Arduino.
DIY GEIGER COUNTER DEVELOPERS WEBSITE:http://www.sites.google.com/site/diygeigercounter/
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 theGeiger Sketch folder to the same folder as your Arduino program is and remember where that is as that will bewhere you go to save your sketch everytime you make a change to it. There will also be a Library folder that willalso need to be in the same folder. Just remember that the folder has to be the same exact name as the sketchname is. And also within Arduino, you will have to go to preferences and show Arduino where your default sketchfolder is. The major difference with this unit is that because this is the shielded kit, only system version 9 can beused and/or modified. You cannot upgrade to the newer system software but only modify and resave the sketch.
ARDUINO SETTINGS:1. Open Arduino2. Open the saved sketch .ino file, connectyour Geiger counter to the USB withpower switch off.3. Verify the file by clicking the little checkmark icon.4. Click TOOLS, and Select Board type asArduino UNO, and select serial port as thetop tty choice.5. Click Serial Monitor (top right lookingglass icon). Set Baud rate to 9600 andyou should see the CPM, uSv and geigercounter voltage data coming up once perminute.
