• A user is planning a fall research project to simulate the safety limits of magnetic implants exposed to large magnetic fields, while colleagues at the same center are pursuing trans-cranial direct-current stimulation (tDCS) work.  
• The DIY group Grindhouse Wetware is mentioned as also experimenting with tDCS, prompting discussion about the relative merits of mechanical versus biological approaches to biohacking.  
• One participant reports positive early results using the Emotiv EPOC EEG headset for brain-wave entrainment, driving isochronic tones with NeuroProgrammer 3 and maintaining electrodes with a homemade saline solution.  
• A request is made for the full text of a 2002 paper on vinpocetine (DOI link via IngentaConnect), highlighting interest in the nootropic’s mechanism of action and safety profile.  
• A computer-programmer newcomer describes building a desktop-sized CNC mill intended for in-house PCB fabrication as an entry point into DIY biology.  
• A link to a Ponoko blog post (http://blog.ponoko.com/2012/05/25/reprap-printed-circuits/) is shared, showcasing progress in RepRap-based 3-D printing of electronic circuits.  
• Discussion of a Science Exchange blog post critiques the idea of crowdfunding as the “future of science funding,” noting that the platform described does not actually use crowdfunding and questioning the value of micro-grants for trivial experiments.
