Hey everyone, just wanted to share a project I’ve been working on: a complete P9 protocol reference guide. I tried to break down each protocol using a mix of my own experience, the manual, the broader P9 literature, and the wealth of knowledge people have shared on this forum. I think it should also work for the M1, but I do not have any hands on experience with the M1
@Bob I’d appreciate any feedback.
I am also working on a brainwave entrainment guide to the p9, but it still needs some work (and is much more subjective).ICES_P9_30_Protocol_Reference.pdf (25.2 KB)
Hey @MattK, that’s really cool. That will be really helpful for people, and I’m happy to help you with this project when you want my input.
The main thing to know is that the electrical circuit and firmware for the P9 is identical to the M1. The main differences are the internal coil and 9V battery for the P9. The P9 is more difficult for me to assemble and is physically larger than the M1, but otherwise they are functionally identical (see note), so your findings for the P9 should be directly applicable to the M1.
Note: there is one functional difference between the M1 and the P9 that is not obvious but can be important to some people: the 9V battery of the P9 has a greater capacity to deliver electrical current than the camcorder battery of the M1. Usually this does not matter using a single pair of coils. But if the electrical load is increased, such as with a 2x2 coil array or the use of more then one pair of coils using a cable splitter, the 9V battery of the P9 will deliver enough power to fully energize this additional coil load, whereas the camcorder battery can not quite deliver as much power for heavy electrical loads.
