# Key Points from IRC Log

• Discussion of simulating the effects of large magnetic fields on magnetic implants to determine safety thresholds, with mentions of tDCS (transcranial direct current stimulation) as a popular area of research among biohackers including the Grindhouse group.

• A participant shared their work on building a small desktop CNC machine with sufficient resolution for personal PCB (printed circuit board) manufacturing.

• A user reported positive experiences using the Emotiv EPOC for brainwave entrainment in conjunction with NeuroProgrammer 3 software to drive isochronic tones, though noted the inconvenience of electrode wetting.

• Link shared about RepRap 3D printers being used to create printed circuits: http://blog.ponoko.com/2012/05/25/reprap-printed-circuits/

• Discussion about the limitations of science crowdfunding, particularly how it's unsuitable for large projects but might work for microgrants ($250-500) that traditional funding sources like NIH wouldn't support.

• Brief philosophical exchange about longevity with the quote "I will live forever or die trying," followed by a Yoda reference about commitment to goals.
