feat: Initial ZK-Glasses project — IR anti-surveillance eyewear
Complete hardware design for glasses with flush-mounted 940nm IR LEDs that are invisible to human eyes but overwhelm camera sensors: - OpenSCAD parametric models (stealth integrated frame + snap-on clip) - SMD LEDs behind IR-pass filter strips (Wratten 87C style) - ATtiny85 PWM firmware (6 modes, brightness control, auto-off) - SVG circuit schematic (dark-themed, full driver circuit) - 10 rendered preview images (hero, front, cross-section, camera view) - KiCad project shell for future PCB layout Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

|

|

* PB0 - LED group LEFT (8 IR LEDs via N-MOSFET gate)
|
||||
* PB1 - LED group RIGHT (8 IR LEDs via N-MOSFET gate)
|
||||
* PB2 - Tactile button (internal pull-up, active LOW)
|
||||
* PB3 - Status LED (green, current-limited)
|
||||
* PB4 - Battery voltage sense (ADC2, voltage divider)
|
||||
*
|
||||
* Modes:
|
||||
* 0 OFF — LEDs off, MCU in low-power idle
|
||||
* 1 CONSTANT — Full brightness, steady
|
||||
* 2 PULSE_30HZ — 30 Hz square wave (half power draw)
|
||||
* 3 PULSE_60HZ — 60 Hz, matches common camera fps
|
||||
* 4 RANDOM_FLICKER — Pseudorandom on/off, defeats adaptive filters
|
||||
* 5 STEALTH — 25% duty constant (very low visibility)
|
||||
*
|
||||
* Controls:
|
||||
* Short press (<500ms) — Cycle to next mode
|
||||
* Long press (>800ms) — Cycle brightness (25→50→75→100%)
|
||||
* Double press (<300ms) — Instant OFF
|
||||
*
|
||||
* Features:
|
||||
* - Auto-off after 2 hours (configurable)
|
||||
* - Low battery warning: status LED blinks when Vcc < 3.3V
|
||||
* - All timing via Timer0 (no delay() in main loop)

// NOTES
|

// ══════════════════════════════════════════════════════════════
|

//
|
||||
// STEALTH DESIGN:
|
||||
// The brow bar has a thin horizontal slot cut into its
|
||||
// front face. An IR-pass filter strip (Kodak Wratten 87C
|
||||
// or Hoya IR-85) press-fits into this slot. It looks like
|
||||
// a subtle dark decorative accent line — completely normal.
|
||||
//
|
||||
// Behind the filter: a flex PCB strip with SMD IR LEDs
|
||||
// (OSRAM SFH 4726AS or similar, 940nm, PLCC-2 package).
|
||||
// Each LED is 3.5 × 2.8 × 1.9mm — invisible from outside.
|
||||
//
|
||||
// The 940nm wavelength is completely invisible to human
|
||||
// eyes (no red glow), but cameras see bright white spots.
|
||||
//
|
||||
// IR-PASS FILTER OPTIONS:
|
||||
// - Kodak Wratten 87C gel: cheapest, ~$5, can be cut to size
|
||||
// - Hoya IR-85 glass: durable, optical quality, ~$20
|
||||
// - Lee 87C polyester: thin, flexible, press-fits easily
|
||||
// - 3D print in dark PLA, thin enough to pass some IR
|
||||
//
|
||||
// ASSEMBLY:
|
||||
// 1. 3D print frame (PETG, matte black)
|
||||
// 2. Solder SMD LEDs to flex PCB strip
|
||||
// 3. Slide flex strip into brow bar channel
|
||||
// 4. Route wires through temple channels
|
||||
// 5. Press-fit IR filter strips into front slots
|
||||
// 6. Insert batteries into temple tips
|
||||
// 7. Snap in charge port, button, MCU
|
||||
//
|
||||
// PRINT SETTINGS:
|
||||
// Material: PETG matte black (or Nylon PA12)
|
||||
// Layer: 0.12mm (fine detail for filter slot)
|
||||
// Infill: 40% gyroid
|
||||
// Walls: 4 perimeters (structural around channels)
|
||||
// Supports: Tree, touching buildplate only
|
||||
// Post: Light sanding, optional soft-touch paint
|
||||
//
