K80 BORG+plus3 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 byUsername: Brohogan. For over 2 years, I have built and sold about 90 of these kits, with very good results, and fantasticfeedback by ebay customers. All information for this kit is available at the developers website. As I have said before, this ismore of a kit for someone who knows a little bit about electronics but doesnt have the time or patience to build it, or wouldrather someone else do all the dirty work. Having been built by me, of course there will be some imperfections, althoughas minimal as possible. These instructions will help you to understand the basic operation of this meter. Once you haveused it a couple times, it should be pretty easy for you to operate.

OPERATIONOn the face of the unit are 2 LEDS, 2 momentary buttons, and 4 triple pole slideswitches. Follow the label to locate the listed switches below:LEDSAfter powering the GC on, you will hear the beeping of the piezo as your CI-180G GMtube picks up radiation events. The GREEN LED is for radiation events and coincideswith the beeping piezo which can be muted with the mute switch. The RED LED willonly light up when a set alarm threshold is reached. The piezo for the alarm andevents are located beneath the grilled vent below the display.

Switches:1. MOD Mode select momentary switch- does 2 things. When you first power on the unit, you will see this first screen:

Atomic.Dave K80 BORG+plus3 v10.2

This customized first welcome window can be changed if you want, by doing a little programming in Arduino. Refer tothe DIY site for directions at the SOFTWARE section. But the default is now set to my name, Kit 80, and the second line isthe Geiger Counter name, and the version of software that the AT328 chip is running v10.2.

The second window will show this:300 CPM=1 uSv/h Running at 5.24V

The first line refers to the conversion rate of CPM to uSv/hr for the CI-180G tube (300) this can be changed either inthe program sketch, with Arduino, or with the Sony wireless remote control which I will explain later. The second line refersto the current voltage that your system is running at. This is a 5 volt system. The 3400mAh 3.7v lipo battery is boosted to5v with a pololu booster. Everytime you start up your GC (geiger counter) it will show you this so you will always know yourcurrent voltage.

The third window will show something like this:Alarm Set ?Now at 500 CPM

At this point, you can gently hold down the MOD button to incrementally change the Alarm threshold number. Onceyou stop holding the button and wait, it will be set to the current number shown on the screen and will stay there until youchange it either again restarting and waiting for this part, or by using the included remote control to change it. You can alsochose from units of measurement such as CPM or uSv/h for the Alarm.2. PWR Power switch controls the power and charging of the GC. Up turns it on, Middle turns it off, and Down while charg-ing the GC. To charge the GC, put the USB switch at the bottom panel to the Right, and the RED LED just above the USBpower switch will remain constant RED while charging, and will turn BLUE when charging is complete. If you wish topower the unit with the USB in, and bypass the batteries for extended periods, put the Power switch in the middle position,and put the USB power switch to the left3. LTS This is the Light switch that controls both the GREEN Event LED and the LCD Backlight. Up turns on both, Middleturns both off, and Down turns on just the LED, and turns the Backlight off for power saving. 4. ALM The Alarm switch controls the Alarm LED and Piezo. Up for both on, Middle for both off, and Down for LED onlyon. This makes for a silent visual alarm.5. SND The Sound switch controls the Event speaker. Up for tone mode, Middle for mute, and Down for Standard ClickMode. More on Tone Mode later.6. NULL The Null momentary switch works only when in Tone mode for the event speaker. When you are scanning inTone mode, you can push this to reset the sensing to zero. As you get closer, you can keep pressing this to reset onceagain to zero. Tone mode also has a sensitivity adjustment when using the wireless remote control. Default is set to 4, andincreasing will create more sensitivity.

OTHER SWITCHES, BUTTONS, PORTS, DIALSA. At the top and to the left of the LCD is the LCD contrast dial. As the LCD is used, it might get to a point for you to

readjust the contrast for it. Not a big deal, while the backlight is on, gently take a small screwdriver and turn it to the left orright until it appears to have the best contrast.

B. Located on the bottom plate and to the left is the OUTPUT multi-port used for Geiger Bot (with the included G-Botcable), and for Geiger Graph (with the optional USB cable) Just plug in the Geiger Bot cable into this with the 3 conductorplug, and the 4 conductor into your iphone or ipad. Or plug the optional Geiger Graph 3.5mm to USB cable into the port,and into a USB on your PC, then follow instructions to run Geiger Graph. It also serves as a mono audio output for silentlistening with headphones, or with the included 3 conductor to 3 conductor M-M audio cable, you can run sound baseddata logging software or amplify the clicking.

C. In the middle of the bottom plate is the USB power and charge control switch. Please leave this in the middle positionwhen not in use. If you want to power the GC without using the batteries- 1. Turn off the GC (middle position) with the PWRswitch above. 2. plug into the usb port and run the cable to a 5v source such as a wall charger, cigarette adapter, pc, mac orlaptop usb output. 3. Push switch to the left PWR position. To charge the GC- 1. PWR switch down to CHARGE position. 2.Plug into USB source. 3. Push switch to the right CHRG position. When you do this, a RED LED comes on above this switchand will remain RED till it is done charging, then the RED LED will become BLUE.

D. On the right side of the bottom plate is the Mini USB FTDI output/input for programming in Arduino. This also is usedto charge the internal Lithium Ion battery (with the power switch in the bottome position.) Or it can be used to power the GCfor extended periods, however when you power it this way, I would advise to turn off the LCD backlight. But its ok to turn it ononce in a while, but I wouldnt leave it on for extended periods. When uploading any new changes to the program sketch, youwill need to have this switch in the up position white it is plugged into your pc with the USB cable. This same USB is used forArduino programming as well as used as an output for usb based FREE Radiation Logging software. To use this software,you must download from this site, and install on your laptop or PC. It is not available for Mac.

REMOTE CONTROL SYSTEM: This adds some conveniences such as the ability to adjust certain things on the GC without the need to plug into your

PC or mac. It is already setup to work. All you have to do is point the remote towards the IR window (below the display be-hind the steel speaker grill), and push the power button on the remote to start. As soon as you do that these options willpop up. 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 you reachthe desired amount you push ENT to enter it into the system.

The keys on the Remote Control perform these functions:On/Off enter or exit the menu system. "DISP PERIOD (MS) is the first prompt you will see.Channel Down or Down Arrow moves to the next menu optionChannel Up or Up Arrow moves to the previous menu optionVolume Up or Right Arrow increments the value already set for the current option or toggles an optionVolume Down or Left Arrow decrements the value already set for the current option or toggles an optionEnter finalizes the entry in the current menu option if changes were made. When used out of the menu, it acts like the"null" button to reset the tome.Digits 0-9 for direct entry of values (instead of Volume or Arrows) must use Enter after using digits.Decimal Point - enters a decimal point - used when setting the ratio.Mute used when out of the menu mutes the speaker when in "tone mode" (see below) or the piezo if that mod hasbeen made to the Geiger board.

Menu Options:Initially, menu options are set to defaults. Settings made will be stored in EEPROM on the ATmega328, so they will be ineffect when you power back on. Here is a brief description of each menu option: DISP PERIOD (MS) - The number of milliseconds before the display refreshes. 5000 (5 sec.) is a good setting.(Display counts are based on a "running average" I do not recommend settings of less than 5 seconds.)LOG PERIOD - When to write the CPM, 'dose', and MCU voltage to the serial output. Zero means logging is turned off.CPM->[DOSE] RATIO - Sets that ratio for the type of GM tube used. Note this ratio will depend on the dose unit being displayedALARM THRESHOLD - When the CPM or DOSE units is greater than this value the alarm is triggered. (See Alarm andSecond Screen below) Unlike the button, any value may be entered.DOSE UNIT - Use the arrow keys to select the name of the unit for the dose value - "uSv/h", "uR/h" or "mR/h".ALARM UNIT - Sets whether the alarm is based off of CPM or the DOSE unit. Use the arrow keys to select.SCALER PER (MIN) - Sets the period for the second scaler.BARGRAPH MAX CPM - Sets the CPM that will give a full scale reading on the bar graph. This also affects tone mode(see below)TONE SENSITIVITY - Determines how sensitive the tone is to changing activity. Low numbers are more sensitive. USE RADLOGGER? (v10.1) - When "Yes" serial output is compatible with Radiation Logger application - see Android /PC BT Graphing page.REG. VOLTAGE - Displays the voltage powering the MCU (Vcc). To a large degree, this represents the state of the battery.

Note that each menu setting has a minimum and a maximum setting. Entries that are out of bounds will revert to the mini-mum or maximum.

DISPLAY BAR GRAPH: The display has a new bar graph style with placeholders and is much more responsive. It now updates 20 times per sec-ond. The tone is also updated at this rate when used.

Auto-precision - decimals are dropped from the displayed dose rate as it gets larger. Beginning with v10.1 the LOG PERIOD can now be set to intervals of less than 1 minute. Valid settings are OFF, 2s, 3s,4s, 5s, 6s, 10s, 12s, 15s, 20s, 30s, and 1 minute intervals up to 720 minutes.

"Tube Select" is still supported where grounding I/O pin 9 will use an alternate ratio for CPM to Dose unit. The CPM->DOSE RATIO in the menu will set and save which ever ratio is selected at the time it's used. This allows setting of boththe primary and alternate ratios.

The current state of the the mute button and the scaler mode are saved in EEPROM and the Geiger kit will come up inthose states the next time it's powered on.

A "reset all" #define can be set. When uploaded the EEPROM is reset to all the default values. This may be useful if theEEPROM contains invalid data from a previous release.

Another #define can put the counter in a test mode. 360 CPM is simulated. Interrupts are not producing the count so itcan be affected if tone mode is on.

Major restructuring of the code base including use of tabs and memory saving techniques.

ABOUT DOSE UNITS:The menu allows you select the name of the dose unit that appears on the display. However, to be clear, there is no

built in conversion between them. Instead the CPM->[DOSE] RATIO is adjusted depending on the name of the DOSEUNIT selected. For example, 175.43 is the default set for the SBM-20 with uSv as the dose unit. Suppose you pick "mR"as the dose unit name, and want to measure in milirems. ("mR" more correctly abbreviates as milliroentgens but is used tosave display space.) The rem is defined as .01 seivert. Therefore, to use the same ratio that was designed for the tube,you would multiply that ratio by 10. You would enter a CPM->[DOSE] RATIO as 175.43 x 10 or 1754.3. Likewise if youwanted microrems ("uR") you would divide the ratio by 10 and enter 17.54.

If you do want to use roentgens (used in older instruments) this source states that they are .96 rem in soft tissue. Sothe CPM->[DOSE] RATIO for actual mR would be 175.43 x 10 x .96 or 1684.1. (for uR it would be 16.84)

PLEASE REFER TO THE DIY GEIGER COUNTER DEVELOPERS WEBSITE FOR FURTHER INFORMATION: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 the Geiger Sketch folder to the same folder as your Ar-duino program is and remember where that is as that will be where you go to save your sketch everytime you make a change to it. There will also be a Library folderthat will also need to be in the same folder. Just remember that the folder has to be the same exact name as the sketch name is. And also within Arduino, you willhave to go to preferences and show Arduino where your default sketch folder is.

ARDUINO SETTINGS: Brohogan Software system version 10.21. Open Arduino2. Open the saved sketch .ino file, connect your Geiger counter to the USB with power switch off.3. Verify the file by clicking the little check mark icon.4. Click TOOLS, and Select Board type as Arduino UNO, and select serial port as the top tty choice.5. Click Serial Monitor (top right looking glass icon). Set Baud rate to 9600 and you should see the CPM, uSv and 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
