Andrew,
I'm really sorry about the 1R0 resistors but I definitely haven't opened the already packed items. I've only done some kind of re-packing in a way that all the stuff fits into the box and survives the shipping. Please tell me if you decide one day to use this resistors, I'll send you the one you are missing, I got one spare set from Nikon1975.
BR, Uwe
For all those protection board subscribers :
Alexis tested the finished protection board for fit onto the case. Everything works as expected, but he felt that the PCB flexing when he pushes the push-button. The push-button force is only the 1N or so required to engage the micro-switch. So functionally there is no reliability issue. But it is true that there is no mechanical limiter to prevent you from exerting more force than required.
What I suggest is that before building the entire protection board, just solder on the micro-switch, mount the PCB onto the front panel and test it with the push button. If many of you feel that you do not have delicate enough fingers, and need a more rigid PCB, we can arrange a new batch made (at cost) to 2mm FR4 instead of the current 1.5mm This will increase the stiffness by a factor of 3.
Even though we consider this a physiological issue rather than technical, all future batches will automatically get 2mm PCBs, just to avoid any issues of the kind.
