- EEG-based BCIs (e.g., Emotiv) are fundamentally limited to a few dozen bits per minute, making them unsuitable for fast-paced gaming; visual-P300 spellers top out at ~92 bits/min with extreme training.  
- A participant is actively seeking a custom adeno-associated virus (AAV) vector for gene-therapy delivery to the retina, aiming to extend human color vision from trichromacy to tetrachromacy or even pentachromacy (including UV) based on successful primate studies.  
- Discussion of nootropics included comparative potency and anxiolytic effects of aniracetam vs. piracetam, the necessity of choline co-supplementation, and skepticism about CDP-choline’s superiority over other choline sources.  
- A DIY supplier (pureacetam.com) was mentioned as a low-cost source for piracetam, while another member offered custom synthesis services for rare compounds (e.g., PL-6983, Bremelanotide) at ~$5 k+ per batch.  
- Bitcoin was highlighted as the preferred payment method for anonymous transactions, contrasting with PayPal and cash-by-mail for purchasing research chemicals.  
- Requests circulated for a “darknet-savvy sysadmin” to help run an entire business over Tor or similar anonymity networks, plus a conventional webmaster/sysadmin for routine site maintenance.  
- Backyard Brains’ acceptance into the Start-Up Chile program was noted as a milestone for open-source neurotech ventures.
