A wonderful kit.

For Arduino IDE Geiger Counter DIY Kit ver.2 with LCD

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.

Good easy build kit - not quite the precision I wanted

For Frequency Counter DIY Kit w/LCD 10Hz-250MHz

I enjoyed building this kit. The instructions are quite sparse and there is a mistake in them - 10k and 100k trimmer pots are swapped in the parts list (but are right on the diagram).I actually installed the oscillator the wrong way around and fried it on my first go - but that was my fault. You have to be careful where the dot is on the circuit diagram (writing on the crystal will be upside down with respect to the board on a correct install)

Again - not quite the precision I was after - which is 1 KHz on the Mhz range - but I should have read the specs more closely so my fault again.

The accuracy is 1% or better, depend also on sampling period settings 1000ms/100ms

dos what it says

If new into kit building read and digest if unsure ask one who knows also with resistors check with a meter another tip photo both sides of pcb before building

Hello Alexey,
Kit received yesterday (very fast) and very well packed, assembled this morning and is working good at first shot !
Just a remark : Labels of Parts P1 and P2 are inverted in the bill of materials
Thank you for all and ready for a new project with Tindie
Have a nice day,
Regards,
James.
