• The #hplusroadmap community migrated the entire DIYbio FAQ from the declining OpenWetware platform to a self-hosted ikiwiki instance at diyhpl.us/wiki, using git-fast-import to preserve 477 page revisions and adding an auto-updating index.  
• A new open-hardware wearable rig was specified: ST1080 head-mounted display, Odroid single-board computer, Twiddler 2.0 chorded keyboard, and a 10-cell 18650 battery pack, aiming for mobile, always-on augmented cognition.  
• Ultra-low-cost software-defined radio experimentation was popularized: $20 RTL2832 DVB-T dongles were shown to function as wide-band receivers, with live WebSDR demos and discussion of 1.8 GSPS ADC boards for side-channel CPU attacks.  
• Optical diffraction was dissected for DIY use: a DVD’s spiral track serves as an inexpensive diffraction grating (not a prism), and blazed gratings can be engineered for tailored dispersion, while open-source spectrometers still lag commercial units in SNR and UV response.  
• Magnetic fingertip implants were debated; experienced members warned about sterility and pain, recommended professional body-mod shops or biohack.me, and questioned whether such implants constitute meaningful transhumanist enhancement.  
• Legacy data archaeology occurred: kanzure recovered decade-old PHP scripts and a DIYbio FAQ MySQL dump, then spun up a Debian Lenny chroot on gnusha.org to run MediaWiki 1.12 and export revisions into a standalone Git repository.  
• Media and policy notes included circulating the short sci-fi film “Sight” (Vimeo 46304267) depicting AR contact-lens gamification, debunking an April-Fools story about NYC replacing taxis with driverless Google cars, and observing that biotech employers now routinely drug-screen candidates.
