THREE PORTALS CHOOSE A RABBIT HOLE
Start with the capability that makes you curious.
01
See the invisible
Thermal imagers, spectrum analyzers, inspection cameras, and sensors that reveal what your eyes cannot.
02
Build tiny machines
Mini PCs, single-board computers, cyberdecks, e-ink displays, and pocket-sized workstations.
03
Explore the signals
Software-defined radio, mesh communication, offline networks, and responsible RF experimentation.
POCKET LAB02
Pocket Geiger Counters: What Can Consumer Radiation Detectors Actually Tell You?
Understand tubes, scintillators, dose estimates, background variation, and the limits of pocket radiation instruments.
OPEN FIELD NOTEPOCKET LAB03
Portable Air-Quality Sensors That Map the Invisible Air Around You
How to investigate particles, carbon dioxide, and ventilation without mistaking a sensor trend for a laboratory result.
OPEN FIELD NOTEPOCKET LAB04
Millimeter-Wave Presence Sensors: The Tiny Radars That Know You Are Still There
How 24 GHz and 60 GHz room sensors detect motionless occupancy, map zones, and sometimes track breathing-scale movement.
