I'm afraid you would not have offered this to all of us, if you knew before. I will of course send the "lemon" back to you. Perhaps you can rectify it, so it would be of use for someone else. Wrt the other unit, don't rush, take your time as required. Better enjoy the holidays

I won't turn it into a nightmare for myself. There are stress of course to deliver the units in good order and I will pace through to get it done properly. I actually got a renewed enthusiasm on the project now. I enjoy solving problems /mysteries and these intermittent problems is occupying me.

Thanks for your patience, the new units have a very similar PCB design so I am worried that same issues can occur. And I will play w/ them a bit before releasing them.

Don't worry sending in the faulty unit. Please do that after I send you the replacement. I will repair them and these are super high-demand gift items.

I am adding ground shields on the PCB design and will order some to replace the existing ones. Not sure if this is the cause of the problems but ground shields are always good.

I will report later on.

Don't tell me you have a lemon, we had far too many.
just kidding, another lemon won't surprise me. Just be patient when I pace through a solution.

I do enjoy the NP41 a lot, it's the right size (NP25 too small for everyday use), got a nice, square and simple case. I only use very basic functions though (mostly 4 function calculations). Differences in making 1 and a whole batch is quite an adventure.
