You will be directed to a PayPal shopping cart, there you can; change quantities, remove items, calculate shipping or continue shopping.
You can checkout with PayPal using either button. If you don't have a PayPal account they will take your charge card.
Please note: the address you fill out in PayPal is the address your kit will be shipped to. Please fill out your address carefully.
Tariffs, customs duties and other fees are the responsibility of the buyer.
Since these are unassembled kits, I can not accept returns on kits you started to build. On the GK-B5 all parts are through-hole however, some kits have a few surface mount components, In general, assembly requires good soldering skills. I do not recommend these kits for those not familiar with soldering PCB boards, or those who don't expect to read the assembly instructions. Please read the Overview for the kit you plan to purchase so you know what you should expect. 


Geiger Kit - GK-B5:
The current availability of the Geiger Kit is  - In Stock

GK-B5 - is the newest model of the classic Geiger Kit.


(If you have purchased a kit in the past and just need the NEC Remote to work with the newest software, you can get one here.
Or, if you are in the US, I can send you one for $4 if you PayPal me. Outside the US, you are better off ordering from the source linked.)


Add an LCD to the GK-B5:
(Provided as a service - please only buy displays along with a kit. Thanks)
The current availability of the displays is: White on Blue: In Stock / Black on Green: In Stock
The LCD works with the GK-B5 kit. Two 6 pin male headers are included. Two styles are provided:
The LCD with white characters on a blue background is perhaps nicer looking.
However, the LCD with black characters on a green background can be viewed with the backlight off which can save ~14mA of battery.


Geiger Kit Plus:  (described on the GK-Plus page)
The current availability of the kit is  - In Stock
The current availability of the display adapter is  - In Stock
This kit is not recommend for those who do not have experience in building electronic projects.





Pololu Step-Up/Step-Down Voltage Reg: 
(Provided as a service - please only buy along with a kit. Thanks)
The current availability is: In Stock


This is the Step-up/Step-Down voltage regulator described in the Build Instructions for the GK-B5 and GK-Plus.
It takes an input voltage from 2.7-11.8 volts and outputs a fixed 5V with great efficiency. 
This gives you a lot of flexibility for a power source such as a LiPo for instance.
You may want to order this part directly from Pololu as they have other great stuff.
It's just carried here as a convenience. 



GKnet Kit: (described on the Kit to Internet - GK page)
The current availability of this kit is: n Stock
Introductory price!


To use the GKnet kit you must . . .
  • Be able to use the Arduino IDE to upload a sketch to the chip
  • Purchase a WIZnet W5100 or  ENC28J60 Ethernet Module
  • Have basic soldering and assembly skills

Geiger Shield Kits:  (described on the Logging Shield Kit page)
Sorry, these kits have been closed out and are no longer available. The GK-B5 kit with the Shield kit have been replaced by the GK-Plus kit. 



Other Items of Interest: 
Here are some things I carry as a convenience to customers. Please contact me if you are interested in something.
  •  I have a small stock of tested GM tubes (SBM-20 @ $22 and STS-5 @ $20 ) that I purchased on eBay. Price-wise, they may not be the best deal, but if you are in a hurry for a tube with your order, contact me for price and availability.

  • I have some low cost ($5) FTDI boards similar to this one on eBay.  They do work on Windows with the older v2.10 driver, but the FTDI chip may not be genuine. There is more information about this board on the GK-B5 Software page. A 6 pin female - female cable is included for connection to the kit.

  •  Whenever the version of PCB changes, I build out a kit. So occasionally I have pre-built kits of a previous version which I sell for the price of the kit. What I have varies from time to time, so contact me about availability. Please note that I generally only sell these domestically.
