# Key Points from #hplusroadmap IRC Discussion

• Debate occurred about transcranial direct current stimulation (TDCS) devices, comparing commercial options like foc.us ($249) with DIY alternatives that could be built for much less, with some arguing that medical-grade safety features justify higher costs.

• ThomasEgi shared a simple circuit diagram for a DIY constant current source for TDCS, suggesting that adding a 10mA fuse could improve safety for basic experimentation despite not meeting medical standards.

• Google's Project Loon (balloon-based internet access using 2.4 and 5.8 GHz ISM bands) was discussed, including technical aspects of potentially intercepting or modifying these balloons.

• The Glowing Plant Project sparked discussion about tensions with BioCurious (a community lab) regarding safety guidelines for plant transformation and the ethical implications of releasing genetically modified plant seeds to the public.

• A philosophical exchange emerged about ethics in biotechnology, particularly regarding whether a "self-regulating" approach to ethics in artificial organism development is sufficient when created organisms may outlive their creator companies.

• The channel moderator noted that ethics/morals discussions are generally discouraged in the channel in favor of technical implementation topics, reflecting a community preference for practical over philosophical debate.

• A paper about a drug that increases neuroplasticity was mentioned, though specific details about the compound weren't elaborated in the conversation.
