The kit was an easy to assemble design. A 3d printed case, a battery pack and a probe are also needed. You will need to get a Geiger-Mueller tube to go with it to construct the probe. The instructions provided on the website will help you choose the model best suited to your needs.
As an assembly warning, wait until you have figured out your battery and case before soldering any pin headers to the board. This will save having to unsolder and move them to the other side or choosing bent ones over straight ones.
