What is the spec for input voltage of the diode itself? I understand that an entire pen assembly probably has some kind of voltage divider circuit at the least, if not some voltage regulation built in.
Just wondering if the end product of the pen is built for best performance with 3.0 volts and that using 2.4 volts is underpowering them. If so itd be great if these manufacturers built 2 models, one spec'ed for 2x 1.5v cells, and another spec'ed for 2 1.2v cells. But I guess that would only be possible if the diodes thenselves work at 2.4 volts or lower.
