There are many others DIY Geiger Kits on the market today. All of them are good for their own reasons as amateur devices. When designed MyGeiger version 2.00 we tried to eliminate the design flaw related to all of others DIY Geiger Kits, such as high current consumption and HV fall under radiation load over 0.5mSv/h. MyGeiger ver.2.00 consumes only 5mA at background (other kits can drawn more than 30-50mA even at background); MyGeiger has stable tube HV (other kits has HV fall under real radiation fast count down to 350V); MyGeiger was tested with dose count up to 1000uSv/h (other kits has stability or logging issues during high speed count). MyGeiger ver. 2.00 has carefully crafted electrical circuit diagram with improved software algorithm. As a result, now we have more professional and stable device with all important for portable dosimeter functions, but the project still kept easy for soldering. Even it has SMD componets installed on PCB, you need to solder only DIP through hole parts. Tiny power consumption: MyGeiger ver.2.00 has twice reduced power consumption, now it less than 5mA at background without backlight. At background radiation dosimeter can continuously operate during 200 hours with one 3.7V Li-PO 1000mAh. With one 3800mAh - 4200mAh Li-Ion it can operate during 30 days without additional charging. Tiny power consumption allows you using MyGeiger for pocket continuous monitoring day by day and charge battery when USB is available. Built-in lithium charger: The board has built-in lithium charger with protection circuit which abolishes the need to carry a special li-ion charger. Indicator led will inform you about charge status. You can charge the kit’s battery directly from your computer or from any 5V power supply with USB jack. Another important new function is battery over-discharge limiter protection. When cut-off 3V battery voltage reached, device goes into sleep mode with about 0.5mA (500uA) power consumption. Then you need to power off the kit and connect USB for charging. Powerful MCU: MyGeiger ver.2.00 run on PIC18F2550 powerful microprocessor. It has better performance and bigger memory in compare to the first edition with PIC16F876. Tube high voltage: Now you can select tube voltage for 400V or 500V output. Even under high radiation load, or when battery is discharged, high voltage stays between tube plateau limits. This functions fully controlled by original software algorithm. The algorithm take care about tube voltage under high speed count load and keep HV in recommended plateau. New High Quality Graphic Display: Old MyGeiger kit was running on Nokia 5110 LCD, but unfortunately this model was retired from manufacturing and has many defective samples. That’s why we changed display type to other high quality and bigger graphic LCD with blue backlight. New display has very tiny power consumption and it’s readable in daylight even without backlight. The display comes pre-installed on LCD Shield board. Built-in USB support: Today MyGeiger kit comes with built-in USB support and you can log data to computer directly, without external TTL modules! The kit can log CPM (counts per minute) or Bq/cm2 data every 5 seconds. Logging Software: For CPM data you can use our freeware “Radiation Logger” Windows application or freeware RadMon application. For Bq/cm2 logging we supply link to download third-party UART terminal program, it also freeware and easy to use. Battery Indicator and USB connection detect: New edition has improved battery indicator and USB connection detection. Radiation Dose Units: MyGeiger ver.2.00 can displays radiation dose in uSv/h, mSv/h or uRn/h, mRn/h units. You can switch between the units with “-“ tact button, make a short push once. The counter will remember your choice in eeprom memory. Accumulated dose in uSv units is also presented on LCD. Each time you power the dosimeter, a new accumulated dose count starts. Measuring Period: The dosimeter has moving average radiation counting with every 5 seconds data updates. Auto Scaling CPM Graph: Keeps all cpm readings for the last 5 minutes in graphical representation. The graph is auto-scaling and auto-scrolling with nice flow on the LCD. Maximum Radiation counting ability: Maximum radiation counting ability for geiger kit is correlation of 3 factors: software interrupt capability, high voltage stability and GM tube type. When talking about maximum radiation count, the common mistake is reporting only microprocessor counting ability. But it also important to take into consideration GM tube HV stability under maximum count load. SBM-20 capable to register up to 1mSv/h. This is realistic maximum level even the processor can count more. MyGeiger ver.2.00 was successfully tested under high radiation count load up to 1mSv/h (1000uSv/h) and during the test kit was showing stable HV within tube plateau limits. MyGeiger ver.2.00 mostly intended for home and laboratory usage, testing radioactive samples or monitoring gamma radiation level. Instead of SBM-20 you can connect any other compatible GM Tubes, such as popular 400V/500V alfa-tubes, just remember to change software settings to get right radiation readings. Kit sound and Silent Operation: Kit has improved sound, very close to the classic Geiger counters clicks. You can mute the buzzer and led flasher by pressing “+” tact button for reducing power consumption and silent operation. Your settings are saved to eeprom memory. Alarm: You can set CPM alert value during device start-up. Your choice is written to eeprom memory for next usage. Alert is settable with 10 cpm steps from 10-200 and with 100 cpm steps from 200-5000. When radiation levels becomes dangerous, the LCD backlight will be activated to inform you about high level. Its possible to use alarm function with external relay module or with second alarm buzzer / led, additional wiring required in this case. Geiger Tube Compatibility: MyGeiger ver.2.00 support many 400V and 500V tubes. Default parameters pre-set is for SBM-20. There are several software settings you need to set in calibration menu when using different tube model: “Conversion Factor” used for conversion from CPM to uSv/h units. Default is 0.0057 "BG” maximum normal background CPM level for your tube, default is 30 “SQ” surface area of your tube in square centimeters units, default is 22 “DL” is detect limit, calculated by software from your BG and SQ parameters, you do not need to set this parameter. BG, SQ and DL used for calculating Bq/cm2. Becquerel logging actual for testing small size radioactive samples, that physical size is smaller than tube surface size. Becquerel mode is experimental function that currently we are not guarantee it has high precision results. Becquerel logging mode is not intended to measure background radiation. To select tube voltage you need to set DIP Switch 1. Off position for 400V and On position for 500V. Then trim 2K potentiometer to the middle position. Power the kit and check voltage value on LCD. For 400V tubes it has to be between 400V-450V, and for 500V tubes between 500V-550V. If you read more or less then turn off the kit and trim 2K a little right or left. After check voltage again. Do not trim potentiometer when kit is powered! You need to find optimal settings for the potentiometer.

Factor and BG values can be different for your specific tube and specific geographical position. To determinate your BG value measure the maximum background CPM you get usually in your area. Some countries and places may have maximum natural background levels higher than presented in this table! Computer Logging: MyGeiger has built-in FTDI FT232RL virtual COM Port IC for USB logging. You need USB cable with mini-usb male connector. To allow logging please download and install FTDI FT232RL drivers: http://www.ftdichip.com/Drivers/VCP.htm USB Serial Port Settings: Baud Rate: 2400 8 Data Bits Parity none 1 Stop Bit Radiation Logger Software: Please download the latest version of PC logger software from our website: http://radiohobbystore.com/radiation-logger/ Pre-set counter for CPM output, in kit’s calibration menu “Bq to UART”, press “-” for NO. Radiation logger software works with Windows OS. It allows creating CSV logs file on your PC and build graphs from previously saved logs files. Since 1.4 logger version it support direct uploading to http://xively.com and to http://radmon.org Becquerel Output Logging: Becquerel logging actual for testing small size radioactive samples, that physical size is smaller than tube surface size. Becquerel mode is experimental function that currently we are not guaranteeing its precision results. Terminal.exe is an excellent COM port freeware application with configurable connection settings and ability to create log files. You can use it for writing Becquerel logs data. Download and run Terminal.exe program. Pre-set counter for “Bq to UART” in kit’s calibration menu, press “+” for YES. Powering the Kit: MyGeiger ver.2.00 requires one Lithium Polymer or Lithium Ion 3.7V battery. You can use branded or no-name types, just take care about connector polarity in advance. Main PCB has PH 2.00mm connector that fits polarity for this Li-PO battery from SparkFun https://www.sparkfun.com/products/339 You can use others 3.7V lithium battery types and capacity, but be carefull about right polarity. It's recommended to use at least 800mAh or 1000mAh capacity, but it also possible to run on one 10440 AAA size Li-Ion. In this case you'll need to charge the battery every 2-3 days because AAA size batteries usually has 300mAh capacity only. Otherwise when running the kit with 3800mAh-4200mAh capacity battery you can use the dosimeter non-stop on background radiation count during 30 days. Important point to understand that any additional modules, high radiation level or LCD backlight impact power consumption directly. That's why when using the dosimeter in high radiation area during long term period you need to carry additional batteries or have an option to charge from USB. Good advice for portable charging is solar powered cell phone charger. This devices has 5V output with USB jack.
