Subsequently it became more difficult to present different aspects of the product directly in the listing. Therefore please feel free to ask by messaging me if you have questions.
LCD and included Li-Po/Li-Ion charger. Note: for safety reasons it is important to use LiPo/LiIon batteries which have integrated protections (most Li-Po usually have but check if yours have). If you are unsure, or know for sure, that your battery is not protected (most 18650 Li-Ion often are not protected), please message me and ask for the charger with the integrated protection circuit so I include the right one for your battery. This means, device can be directly (without any converters) powered by almost any 3.7-4.2V rechargeable battery. (above demo videos are for reference only - items depicted are not a part of this listing).While retaining all the previous features and functions of the previous designs. New version is more compact and is mainly based on SMD components. Has a tone mode for search of the radioactive source (like in a metal detector) switchable On or Off with an installed microswitch.
LCD backlight is now switchable On or Off by double-clicking the "MODE" button. Sound is now also switchable On or Off by double-clicking the "TONE-ZEROING" button. Switching between the "Primary" and "Secondary" conversion rates is now done by long-pressing the "TONE-ZEROING" button with an few seconds indication of which rate is chosen on the LCD. Additional potentiometer is installed to reduce the brightness of the LCD backlight (which provides essential battery power savings).High Voltage is now adjustable from. 800V which allows reliable use of most popular Geiger-Müller tubes. JTAG, i2C, TTL level Serial and battery power headers are provided for extension and connectivity purposes. This listing is without the GeigerMüller tube, TTLSerial. In order to use it you need to have a GeigerMüller tube which has it's working voltage in the interval from 100 to 800V. Currently I also have the following tubes in stock (please inquire by message if you need any). SBT-9 (alpha beta and gamma). CTC- 5 (beta and gamma).
SBT11 (alpha beta and gamma). SBT11A (alpha beta and gamma).
SI8B (alpha beta and gamma). SBT10 (alpha beta and gamma). SBT10A (alpha beta and gamma). SI19BG (alpha beta and gamma). Feature - amended geiger kit sketch.
11.0.2 3.3V. The schematics of the device is also available but as links can no longer be given here try to look for impexeris on GitHub.Please read more about features of v. 11.0.2 3.3V below on this page. This device has an integrated IR receiver and a menu system controllable with any NEC. Or Sony type IR TV remote. (note: IR TV remote is not a part of the listing). Besides control of multiple other parameters this feature allows changing CPM>uSv or uR ratio for tubes through the menu without a need to reprogram the firmware. IR remote control pictured below is not a part of this listing but is available as an option for additional 4 USD.
If you would like one included please ask before paying and I shall adjust the e-bay invoice. It is called Universal TV Remote from developer called Twinone.
And open it (when asked which app to use for opening it choose the app you you have just installed). Note: the above custom remote file is when firmware which is configured to work with Sony. System remotes uploaded (this is the default configuration of firmware for boards in this listing). Note: You can choose either.Black-on-Green (default) or White-on-Blue LCD display. A limited number of Black-on-Green with. Displays are available for extra 8.8 USD.
Please contact me by a message if you want a display other than Black-on-Green. Some videos (for reference only - not a part of this listing). Schematics takes its origins from a Geiger counter schematics publicly available on the Internet - on DIYGeigerCounter page and is further advanced with the final schematics freely available.This device is preloaded with adapted GeigerKit sketch v. 11.0.2 3.3V. Is a free software and is available.
Can detect , and ionizing radiation depending on the GeigerMüller tube you shall connect. Simultaneously displays the Count Per Minute (CPM) and equivalent dose rate of radiation in Sv/h on the LCD display.Indicates detection of ionizing particles with clicking sound and flashes of the yellow LED. (has a jumper for disconnecting-muting the buzzer). Has a TTL-serial connector for connection to a computer (more information on connection to computer - below).
When connected to computer counter outputs CPM, Sv/h and power voltage data in one minute intervals. A threshold LED lights up when preprogrammed threshold in Counts Per Minute (CPM) are exceeded. Push-button is provided for initial threshold value setup and change of the display modes (screens) - please reed more about that below in the Software functionality description section. This counter circuit is well suited for use with any other GeigerMüller tubes wether.
Produced for just just or combined + or universal ++ detection. When using other tubes it is important that. Tube is specified to reliably operate in the voltage interval up to 800V.Specified tube anode resistor value is around 5,3 M (note: some other - usually energy compensated ++ tubes could require a different anode resistor value but changing this resistor is easy - please ask). Note: a voltage can be adjusted by trimmer potentiometer present on the PCB. B the CPM to Sv/h ration for that particular tube can be changed by IR Sony type TV remote. LCD display is a 2 Line x 16 character backlit display.
You can choose either Black-on-Green (default) or White-on-Blue LCD display. Please contact me by message is you prefer White-on-Blue LCD installed. Counter is designed to be powered from rechargeable 3.7V/ 4.2V LiPo or LiIon batteries and. The device has a step-down regulator which provides the native 3.3V for the whole schematics.
Note: It is important to connect the power in correct polarity in order to prevent burning that regulator! When connected to computer TTLSerial. USB converter which is not a part of this listing is needed, counter can be powered throughout the TTL-Serial header and draw power from the computer.Note: when powering through the USB adapter, the 3.3V pin should be used for the VCC! With the LCD backlight being Off device draws 15 mA from battery. With LCD backlight fully ON total current drawn is around 44mA however with the 10K LCD brightness trimmer power draw can be reduced up to 18mA. When using Tone mode, power draw can peak to 75 - 100 mA.
Circuit has a TTL-serial connector (the 90 degree bent header) this is a serial connector, however it operates at Transistor to Transistor Voltage levels and can be connected to the computer through appropriate ttl-com port or ttl-usb adapter TTLSerial. USB converter which is not a part of this listing is needed.
When connected to computer Counter can be a powered from the computer b simultaneously outputs to the standard serial terminal CPM, Sv/h and power voltage data in one minute intervals. Therefore this counter is also good opportunity to learn about micro-controllers and change the software to your taste. Alarm threshold settable at power-on (retained in eeprom). Eeprom can be reset to default values by holding the "Mode" button during boot. Alternate display (by press of the button).A "quick response" bar graph (search aid). Tone mode (radioactive source search aid). Alarm (optional): When the CPM exceeds a preset value, the red threshold LED shall be lit.
When the CPM drops back under the initially preset alarm threshold the LED whale go off. The alarm threshold is configured during power up. After the first few screens you will see a "Set Alarm" prompt.
To preset the alarm you have to use a push button or simply let the preset function time out in 3 sec. Of inactivity to keep the then current setting. Pushing the button point shall start a list of alarm settings. Push the button (or hold it down) until you find the desired setting, then release the button to set that last value. After the 600 CPM setting, the choices repeat.
The possible settings increment by 10 until 100 CPM and then by 50 until the 600 CPM setting. There is also a "No Alarm" setting. The chosen setting is retained in eeprom so it does not need to be set each time.
The same push button used to set the alarm is used to turn on or off the second screen. The chosen screen stays on until the button is pushed again. The first time the screen is entered, the totals will begin to accumulate from zero. After accumulation has started, reentering the mode will display the totals that have accumulated.
The second screen shows values for 1 minute and 10 minute periods. While the period is in progress (time not reached) the accumulated counts for the period are displayed. On the 10 minute line, the elapsed time is also shown on the right side. When a given period is complete, the format of the display changes.It then becomes the running average of CPM and uSv/h for the last 1 minute and 10 minute periods. The second screen is updated every 5 seconds. The bar graph on the first screen shows quick changes in counts to make it easier to spot trends when surveying. It has a sample rate of 1/20 of a second. By default Output is configured for Radiation logger software.
Then on the blog look for the article called. How to prepare using Radiation logger. 11.0.2 3.3V has a low battery indiction when the after-regulator voltage decreases to 3299mV. This adapted firmware version contains multiple other features present in original v. 11.0.1 Please refer to the.
