NP-41 Emulator (may be)

But if you don't get the four orders, I might be tempted.

Thanks for taking the 1st unit. And also Sylvian and Etienne. It is working out like the NP-25. With Harald taking on the 1st unit and Sylvian taking one of the 1st batch unit.

These early units are not so much about volume, just 1 or 2 takers is enough as what I need in this phase is to have beta testers to try them so that I can make corrections / adjustment for the volume batch. OTOH if you are adventurous, you got to play w/ the "toy" before everyone else. The initial batch will always be inferior to later batches (as we seem w/ the NP25) as a project goes. So thanks to the early takers.

Let me notice, that the NP41S with the battery in front disturbs my aesthetics. I would have liked to use it without case as I'm used with the NP25. Did you consider placing the battery in the back like in NP41?

I was planning to move the coin cell toward the center as it is obstructing my printed case.
I had placed the coin cell on top to try to make the whole unit thinner. Moving it to the bottom will add 2mm to the thickness.

The current PCB has thru-holes for the battery holders, so one can solder a thru-hole CR2032 holder on either side, though the thru-hole battery holder is even thicker. I will at least add solder pads to the opposite side in future PCB so that we can mount smd holders from either side (at the same position). May be also add alternate ON button position on the original top side battery position.

The battery was placed there kind of intentionally, along w/ the 2 x 8 pin DIP socket (not yet populated). I like to exposed parts to make it look geeky.

Might as well as the community.

1) color for PCB, white? green? black? red? blue? yellow?
2) how does the top side battery design bothers you? a lot? a little?
3) should I combine the 2 "enter" keys into one?
