The GK-plus4 ULTIMATE FULL FEATURED Arduino compatible DIY Geiger Counter Kit number 115 by Atomic.dave This is the fourth model in the GK-plus series of meters, this time with LND712 FEATURES: Internal Alpha Beta Gamma Xray sensitive American made LND712 with Stainless steel grill GPS • SD card writer & FREE SD card for data logging • 1.8" TFT full color display • ATmega1284P microprocessor 3.7v, 4000mAh Lithium Ion battery with USB charging & status LED provides over 24 hours of field time between charges. 7 hours to charge via USB cable and any 5v source. Tone mode makes sensitivity like a metal detector (distance to the source effects pitch of the beep) WIRELESS REMOTE CONTROL for EASY in-field adjustments to: Alarm threshold with range of 0 to 60000 cpm, 2 different Timer averages with range between 1 and 720 minutes, RAD SAMPLE and RAD Stickers, UV keychain LED flashlight, WALL & CAR USB CHARGER CD with drivers, build info, schematics parts list, and program sketch used to program the ATmega chip Tube usv to cpm ratio, & Much more… 6 month FREE Maintenance from date of purchase (Buyer pays for shipping and/or parts if needed, labor is free) Includes calibration or parts replacement labor if something fails in first 6 months. Upgrades or mods not included PC DATA LOGGING SOFTWARE (FREE) (I do not work for these companies, nor do I provide anything other then basic tech support for the programs So please contact the appropriate people using the provided website addresses below for extra support) RadLog Professional http://radmon.org/index.php/download-upload Radiation Logger http://www.rhelectronics.net/store/radiation-logger.html iPhone/iPad DATA LOGGING APPs (FREE)Geiger Bothttps://sites.google.com/site/geigerbot/ Safecasthttp://blog.safecast.org/2014/09/safecast-os-x-app-now-available/ LND 712 End window-alpha-beta-gamma detector Download Specifications in .pdf format GENERAL SPECIFICATIONS GAS FILLING Ne +Halogen CATHODE MATERIAL 446 Stainless Steel MAXIMUM LENGTH (INCH/MM) 1.94/49.2 EFFECTIVE LENGTH (INCH/MM) 1.5/38.1 MAXIMUM DIAMETER (INCH/MM) 0.59/15.1 EFFECTIVE DIAMETER (INCH/MM) 0.36/9.1 CONNECTOR Pin OPERATING TEMPERATURE RANGE °C -10 to +75 WINDOW SPECIFICATIONS AREAL DENSITY (MG/CM?) 1.5 - 2.0 EFFECTIVE DIAMETER (INCH/MM) 0.36/9.1 MATERIAL Mica ELECTRICAL SPECIFICATIONS RECOMMENDED ANODE RESISTOR (MEG OHM) 10 MAXIMUM STARTING VOLTAGE (VOLTS) 325 RECOMMENDED OPERATING VOLTAGE (VOLTS) 500 OPERATING VOLTAGE RANGE (VOLTS) 450 - 650 MAXIMUM PLATEAU SLOPE (%/100 VOLTS) 6 MINIMUM DEAD TIME (MICRO SEC) 90 GAMMA SENSITIVITY CO60 (CPS/MR/HR) 18 TUBE CAPACITANCE (PF) 3 WEIGHT (GRAMS) 8 MAXIMUM BACKGROUND SHIELDED 50MM PB + 3MM AL (CPM) 10 If you are not familiar with Atomic.dave Geiger Counters, they are based on a DIY kit designed by user Brohogan. It has certainly evolved over the past 3 years to have many more features, controls and options then it did back then. All info to create this kit is available on the website below so if you want you can create your own. The schematic and very detailed instructions are available at that site. This is more of a kit for someone who knows a bit about electronics but doesn't have the time or patience to build it. This is a hand crafted device and may have slight imperfection on them, but customers are all remarking about the excellent craftsmanship done on these meters. The components are all new, including the American Made GM tube, from LND, Inc. I will honor a 30 day money back guarantee if you are not satisfied with this item, however buyer must pay for shipping.

There are many videos on his channel that will help you to understand more about what this kit has inside: http://www.youtube.com/user/BroHogan WARNING, IF YOU DO DECIDE TO OPEN UP THE CASE AND LOOK INSIDE, PLEASE DO NOT TOUCH ANYTHING WITH THE POWER ON AS YOU COULD SHORT OUT AND KILL THIS SYSTEM AND I WILL NOT WARRANT THIS KIT FOR DAMAGE DONE. I ship USPS Priority Mail for US, or Ebay Global Shipping International I CAN ACCEPT CREDIT CARDS - WHEN YOU BUY THE ITEM IT WILL ROUTE YOU TO PAYPAL THIS IS WHERE YOU PROVIDE YOUR CC INFO. Check out my other auctions for available Geiger Counters, Parts and Accessories DIY kit Hardware Features: ATmega1284P microprocessor is Arduino IDE compatible with headers for all I/O pins. Designed to be expandable and adaptable - the HV circuit is independent of the processor. High voltage power supply – fully adjustable from 200 to >1000 volts. (powers a larger variety of GM tubes) LED and speaker indicates activity directly from the GM tube, not from the processor. Capable of displaying high CPM counts (over 1,000,000) FTDI connector outputs log data to serial port (low cost adapter required for PC connection not included) SD card data logging with GPS location Software Features: Display in CPM and choice of uSv/h, uR/h or mR/h Graph on the main screen shows last 13 minutes of activity and can be set to auto-resize based on peak or avg. New dose type – xBg shows the percent of average background set Status "LEDs" on screen indicate logging, scaler mode on, and alarm on Max CPM, speed and altitude (if GPS used), low battery and other info are shown on the "status line" Bargraph on the bottom of the screen also shows activity and is very responsive 3 choices for color scheme of the main screen selectable in menu An Information screen shows time / date, max CPM, speed and altitude, etc. A Scaler screen shows two scaler periods. The period length for the second scaler is user defined. Serial logging output output options support Radmon.org and Radiation Logger Alarm for high counts with settable threshold triggers off of either CPM or dose Tone Mode - optionally set speaker to produce a tone that varies in pitch with activity. (like a metal detector) Setup Menu - allows you to configure running parameters and features with the mini-remote. A brief description of the setup menu options: SCREEN ORIENTATION – screen and text adjust for 4 positions – portrait or landscape· DISPLAY SCHEME – set 1 of 3 predefined "skins". BRIGHTNESS - Adjust the backlight brightness GRAPH SCALE MODE - two "Auto" modes allow the graph to update its range based on the max peak or average. BACKGROUND CPM - the average background rate you enter is used if the DOSE UNIT is set to “xBg”. TIME SETTINGS – set time and date if not using a GPS also Auto DST and various time date, formats and metric or imperial units GPS MODULE – choice of one of the four supported GPS module types (EM-406a/411, U-blox 6, Adafruit MTK3339, SkyTraq ST22) DISP PERIOD, SD CARD LOG PERIOD, SERIAL LOG PERIOD, SCALER PERIOD – settable CPM->(unit), ALARM THRESHOLD, BARGRAPH MAX CPM, TONE SENSITIVITY - settable
