- **DIY maskless UV lithography**: Participants explored using UV-absorbent inks (Sharpie invisible ink, “spectral marking pigment” BMX-1000) printed on transparency film as photomasks for polymer exposure, aiming to circumvent the ~200 µm resolution limit of laser-printer toner by instead steering a UV LED with hacked hardware.

- **Hard-drive laser galvo for micro-patterning**: The group converged on repurposing hard-disk voice-coil actuators as fast, low-cost XY galvanometers; links to $10 DIY laser-scanner projects and Make Magazine tutorials were shared as proof-of-concept for steering a UV beam across a photosensitive surface.

- **Piezo vs. voice-coil actuation trade-offs**: While piezo “tweets” offer nanometer-scale motion (≈0.16 µm/V, 2.9 µm total), their range is too small for centimeter-scale lithography; tilting a mirror on a hard-drive arm provides the required angular sweep at millisecond speeds.

- **Head-mounted display sourcing**: Discussion of affordable near-eye displays centered on the MyVu Crystal (640×480, <$1 k) and exotic “Teleglass T3-F” monocular eyewear (320×240, aimed at medical/microscopy markets); the need for digital (DVI/HDMI→LVDS) input from a BeagleBoard was highlighted.

- **Ultra-fast battery chemistry**: A Nature paper on LiFePO₄ cathodes engineered with off-stoichiometric surface phases was noted, claiming full discharge in 10–20 s—relevant for wearable or implantable transhumanist devices.

- **Amateur space imaging**: Links to high-resolution ground-based photographs of the ISS and Shuttle were circulated, illustrating the rapid advance of citizen-accessible optics and tracking systems.
