# Key Points from IRC Discussions

• Participants discussed DIY possibilities for the Neurophone, a device that transmits sound through skin contact, comparing a potential $10 component build versus the commercial version costing 649 EUR.

• The group explored innovative tactile VR interface concepts, including combining ultrasound with water/gel and using LEDs as dual-purpose light emitters and touch sensors.

• Kanzure announced taking over management of the Gada Prize for 3D printing technology, with plans to revise problematic criteria including PCB printing requirements and unattended operation specifications.

• A significant medical case was discussed where the experimental monoclonal antibody TGN1412 caused catastrophic systemic organ failure in human trials despite being administered at a dose 500 times lower than what animal testing indicated was safe.

• The conversation covered various 3D printing technologies and business relationships, including the PP3DP commercial printer ($1500) and connections between RepRap, MakerBot, and other initiatives.

• Participants shared research on vitamin D supplementation, noting that UV irradiation dramatically increases vitamin D content in foods (particularly mushrooms, which showed an increase from 8 IU to 461 IU when exposed to UV light).

• Someone proposed an on-demand custom pill service that would combine multiple supplements into a single personalized pill, addressing the need for individualized supplement solutions.
