Terms and Conditions:
A flat rate of $3.00 for US shipping and $8.00 for international shipping is applied to all orders at checkout. 

Kits are shipped USPS 1st Class (Economy). Shipping time for international is usually about 3 weeks, but some countries will take longer.
Economy shipping does not provide a tracking number for overseas orders. (However the Customs # will provide tracking at least while in the US.)

To order, select the type of kit from the drop-down and click the "Add to Cart" button. A PayPal shopping cart will open, there you can; change quantities, remove items, or continue shopping. 
Use the Continue shopping > link to add more items. When you are finished with your cart, checkout with PayPal using either button. If you don't have a PayPal account they will take your charge card. Just follow the prompts. Shipping is added during the final checkout.

Please note: the address you fill out in PayPal is the address your kit will be shipped to. Please make sure your address is correct.

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 most kits all parts are through-hole, however some have a few easy 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.

 Pololu Voltage Reg: 
$5
 The current availability for this item is  - In Stock

This is an optional Step-up/Step-Down voltage regulator for the GK-B5 and GK-Plus Geiger kits.
 Installation is described in the Build Instructions.

It allows 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 can order this part directly from Pololu as they have other great stuff. 
It's just carried here as a convenience.
 
This item is only available along with one of the Geiger kits above.
