TEKO+plusK85 CI-8B Geiger Counterby Atomic.dave [email protected]

This is yet another one of a kind, custom hand-made Geiger Counter built by Atomic.Dave. It is based on a kit

esigned by John Giametti (username: Brohogan) I have been building his DIY Geiger counters for over two years having

uilt and sold over 80 of them. Much of the information for this kit is available at the developers website. This is more of a

t for someone who knows a little bit about electronics but doesnt have the time or patience to build it, or would rather

omeone else do all the dirty work. Having been built by me, of course there may be some imperfections, although as

minimal as possible. This particular unit not only has a wireless remote control for in field programming, it also has the very

ensitive pancake Russian tube, the CI-8B (SI-8B). Please remember to use averages and know that with the extremely

arge diameter of the mica window, the background rate is much higher than other units. Approx 120 cpm.

A. SELECT (RED to the left of the tube) momentary switch does 2 things. When you first power on the unit, you will see:

Atomic.Dave K85TEKO plus V10.2

This customized first welcome window can easily be changed if you want, by doing a little programming in Arduino.

Refer to the DIY site for directions at the SOFTWARE section. But the default is now set Atomic.Dave K85, and the second

ne is the Meter Name, and the version of software that the AT328 chip is running V10.2.

The second window will show on first line the current uSv to CPM conversion rate. For this extra large pancake tube,he CI-8B, after some research online, it was calculated that the conversion rate is 440.

440 CPM=1 uSv/hRunning at 5.58V

have preset this for your Tube, but later if you wanted to you could change this rate with either 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

t. This is a 5 volt system. The 3000mAh 3.7v lipo battery is boosted to 5v with a pololu booster. Everytime you start up

our GC (geiger counter) it will show you this so you will always know your current voltage.

The third window will show this:

Alarm Set ?Now at 500 CPM

At this point, you can push the Select button to incrementally change the Alarm threshold number. Once you stop hit-

ng the button and wait, it will be set to the current number shown on the screen and will stay there until you change it ei-

her again restarting and waiting for this par t, or by using the included remote control to change it. You can also choose

om units of measurement such as CPM or uSv/h for the Alarm with the remote. It also acts like a stopwatch starter for the

caler mode. It has two preset times of 1 minute and 10 minute averaging. You can change this with the remote, or theketch when connected to pc. Although it is much easier with the remote obviously.

B. ALARM switch controls the Alarm LED and Piezo. Up for both on, Middle for both off, and Down for LED only on. This

makes for a silent visual alarm.

C. LIGHTS switch controlsthe Event LED (GREEN) and the LCD Backlight. Up turns ON both, Middle turns OFF both,

nd Down turns the LED on, and the Backlight off.

D. POWER switch controls the power and charging of the unit. Up turns on the unit, Middle turns if off, and Down is for when

ou charge the unit. When the unit is charging, the tiny RED LED on the upper right side will remain constant RED while

harging, and when charging is complete, it will turn OFF. If you wish to power the unit with the USB in, and bypass the bat-

eries for extended periods. Switch in middle position, and flip up switch on top right of unit next to the mini USB port.

. SOUND switch controls the Event speaker. Up for tone mode, Middle for mute, Down for Standard Click Mode. More on

one Mode later.

. NULL (RED to the right of the tube) momentary switch and works only when in Tone mode for the event speaker.

When you are scanning in Tone mode, you can push this to reset the sensing to zero. More on this later.

EDS

Right away, you will hear the clicking of the speaker as your GM tube picks up radiation events. There are two LEDs belowhe LCD. The Right is GREEN which is for radiation events and coincides with the clicking speaker which can be muted

with the mute switch. It can also be turned off by the Light switch. The Left one is RED for the Alarm which will only light up

when a set alarm threshold is reached. It can also be turned on or off.

OTHER SWITCHES, BUTTONS, PORTS, DIALS

EW- Added 2 new switches to the side left and right of the unit. The left one is used to turn on and off the internal

R for the remote control (located just above the tube). LEAVE THIS OFF WHEN NOT USING THE REMOTE TO PRO-

GRAM THE UNIT. If you leave it on, the IR has a tendancy to pick up signals from other remote controls and will

ause the unit to not function properly. The right side switch is used to power the unit with the USB cable plugged

n. This must be DOWN when charging the unit. Flip this up to turn it on. Down when not powering the unit with the

SB. When powering the unit for long periods with the USB, please flip the main POWER switch to the middle OFF

osition. There is a toggle switch across from the BNC connector. This double function toggle is to chose internal

r external GM tube, as well as to switch between the corresponding uSv to CPM conversion ratio.A. At the very top left side of the meter is the MULTI-PORT used for Geiger Bot (with the included G-Bot cable), and

or Geiger Graph and RAD OSX (with the optional 3.5mm to USB cable) Just plug in the Geiger Bot cable into this with theconductor plug, and the 4 conductor into your iphone or ipad. Or plug the included 3.5mm to USB cable into the port,

Two momentary switchesare described in these twogrey boxes. The Select is tothe left of the tube, and theNULL reset is to the right

nd into a USB on your mac or PC, then follow instructions to run those programs. It also serves as an audio output forlent listening with headphones, or with the included 3 conductor to 3 conductor M-M audio cable, you can run soundased data logging software.

B. Below the Multiport on the same side is the IR power switch. Up for on and down for off. I found that sometimes theensitive IR (located just above the LCD display inside the case) would pickup my neighbors remote and strange things

would happen for no reason, so I would suggest keeping it off and on only when programming.C. Next 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

ig deal, while the backlight is on, gently take a small screwdriver and turn it to the left or right until it appears to have theest contrast.

D. On the top Right of the meter is the Mini USB FTDI output/input for programming in Arduino. This also is used toharge the internal Lithium Ion battery (with the power switch in the bottome position.) Or it can be used to power the GCor extended periods, however when you power it this way, I would advise to turn off the LCD backlight. But its ok to turn itn once in a while, but I wouldnt leave it on for extended periods. When uploading any new changes to the programketch, you will need to have this switch in the up position white it is plugged into your pc with the USB cable.

E. Below that is the USB power on/off switch. Up for on, and Down for Off. This is used for powering the unit for longeriods and bypassing the internal Lipo battery. Put the GC Power switch in the middle position before using this power

method. I would also suggest turning off the LCD for long periods just to save the life of the LCD.F. Directly below the USB power on/off switch is the charging LED indicator. RED for charging, and BLUE when

harging is complete. Protective overcharge circuitry is built into the include Lithium Ion rechargeable battery.

REMOTE CONTROL SYSTEM: TURN ON THE IR WHEN PROGRAMMING THE SYSTEM. TURN OFF AFTER.This adds many conveniences such as the ability to adjust certain things on the GC without the need to plug into your

C or mac. It is already setup to work. All you have to do is point the remote towards the IR window, and push the powerutton to start. As soon as you do that these options will pop up. Use the channel button to move thru each option, andse the volume buttons to move up or down within those options. You can also use the number pad to input numbersather than using the up down of the volume. After you reach the desired amount you push ENT to enter it into the system.fter you are done, hit power again to get out of this mode.

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.

CH Down moves to the next menu optionCH Up moves to the previous menu optionOL Up increments the value already set for the current option or toggles an optionOL Down decrements the value already set for the current option or toggles an optionNT 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.

ERIOD enters a decimal point - used when setting the ratio.MUTING used when out of the menu mutes the speaker when in "tone mode"RECALL used when out of the menu - switches between the main screen and the scaler screen

Menu Options:nitially, menu options are set to defaults. Settings made will be stored in EEPROM on the ATmega328, so they will be inffect 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.)OG 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 dis-layed - see DISPLAY UNIT. Use the DEC PNT or AV/TV key to set a decimal point.

ALARM THRESHOLD When the CPM or DOSE units is greater than this value the alarm is triggered. Unlike the button,ny 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.

CALER 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

ONE SENSITIVITY Determines how sensitive the tone is to changing activity. Low numbers are more sensitive.SE RADLOGGER? 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. Ins

he CPM->[DOSE] RATIO is adjusted depending on the name of the DOSE UNIT selected. For example, 175.43 is the default set for the SBM-20 with uSvas

ose 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 to s

isplay 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

nter a CPM->[DOSE] RATIO as 175.43 x 10 or 1754.3. Likewise if you wanted 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. So the CPM->[DOSE] RATIO for actua

would be 175.43 x 10 x .96 or 1684.1. (for uR it would be 16.84)

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 y

rduino 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 Libra

older that 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 Arduinowill have to go to preferences and show Arduino where your default sketch folder is.

ARDUINO SETTINGS: Brohogan Software system version 10.2

. Open Arduino

. Open the saved sketch .ino file, connect your Geiger counter to the USB with power switch off.
