# Key Points from IRC Log

• A consumer tDCS (transcranial direct current stimulation) device called "foc.us" was shared, which claims to pass small electric currents (<2.05mA) through the prefrontal cortex, though participants expressed skepticism about its marketing claims and high price point.

• Discussion of DIY tDCS alternatives revealed that OpenStim is defunct, with kanzure sharing a resource directory of tDCS papers (http://diyhpl.us/~bryan/papers2/neuro/tdcs/) for those interested in building their own devices.

• A user named kirka shared their C. Elegans simulator project (700 lines of Common Lisp code) that models physics but not yet the nervous system, which led to discussion of more advanced worm simulation projects like OpenWorm.

• Resources for DIY biology were shared, including kanzure's extensive paper collections on molecular biology, longevity, and microfluidics at diyhpl.us, plus a wiki with DIYbio FAQs and news.

• Participants discussed bacterial transformation techniques for DIY biology projects, with debate about whether heat shock or electroporation methods are more practical for home labs, and what basic equipment (incubators, water baths) would be needed.

• A company called "Bioglow" was mentioned as working on bioluminescent organisms, with some participants expressing interest in glowing organisms like cats while others showed fatigue with the concept.
