I got the kit all soldered up and are now waiting for a handheld enclosure to arrive from Hong-kong, so it will be a little while before I can show it off 🙂
A few suggestions to the manual for the KIT1.
The two pictures of the component layout is too crowded, it is in some cases impossible to read the component name on it (R14, R15 etc)
The overall print quality is not up to par, the schematic is very fade at the edges of the paper.
The only thing I could wish different for the PCB would be that the corner holes had enough space for a nut or bolt without being dangerously close to the end terminals for the GM tube.
Else it was pretty much a walk in the park to solder the unit and it was online within a couple of hours from unpacking the box 🙂
