# Key Points from #hplusroadmap IRC Discussions

• Carbon nanotube fiber microelectrodes (CNTfs) were discussed as superior alternatives to traditional metal electrodes for neural recording, offering lower impedance, reduced inflammatory response, and weeks-long stable neural activity recording capabilities.

• Participants explored advanced microfluidic DNA synthesizer designs, noting that a 1024x1024 pixel system would represent significant progress, while even a 600x800 design using digital light processing (DLP) technology could be practically useful.

• The group discussed how modern digital micromirror array technology could enable affordable ($1000) light-directed oligonucleotide synthesis devices with 1920×1200 resolution at 8.5μm pixel pitch.

• A breakthrough 3D NAND flash memory technology from Intel and Micron was highlighted, capable of storing 437GB in a space the size of an M&M candy, representing a major advancement in storage density.

• Biohackers' experiments with Chlorin e6-based "night vision eyedrops" were shared as an alternative to vitamin A-restricted diets for enhancing night vision capabilities.

• The Black-Swift project was discussed as a promising coin-sized computer featuring a 32-bit CPU, megabytes of memory, integrated Wi-Fi, USB 2.0, and multiple interfaces including 25 GPIO lines, with potential applications as a quadcopter controller.

• The channel showed interest in audio programming environments, with Pure Data, Csound, ChucK, and Max/MSP mentioned as alternatives to overtone/supercollider for audio synthesis and algorithmic composition.
