# Key Points from #hplusroadmap IRC Discussions

- Mirage335 was reported to be working on EEG technology and seeking collaborators specifically for electrode manufacturing, indicating ongoing grassroots development in brain-computer interface hardware.

- Participants engaged in a technical discussion about retinal implants for vision restoration, concluding that current technology could feasibly achieve grayscale vision at 32x32 or 64x64 resolution, while 160x144 resolution would be pushing technological boundaries.

- The conversation included detailed explanations of human vision physiology, describing how the retina's three types of cone cells and rod cells transmit information through the optic nerve's 700,000-1.7 million neurons, providing context for the challenges of artificial vision systems.

- Kanzure shared information about OpenBCI, a new open-source EEG project on Kickstarter that leverages Arduino technology and the ADS1299 chip, representing the growing democratization of brain-computer interface technology.

- Technical discussions covered differential input ADCs (analog-to-digital converters) for biosignal acquisition, including specific requirements for power supply, PCB layout, and shielding, demonstrating the community's focus on practical implementation challenges.

- There was interest in neodymium implants with reference to Quinn Norton's 23C3 conference presentation about her experience with magnetic implants, showing the community's engagement with practical biohacking.

- A question about anonymous genome sequencing services without "know your customer" (KYC) requirements highlighted privacy concerns within the biohacking and personal genomics communities.
