Bolt-together cargo tricycle whose frame is cut from flat sheet steel by any laser or waterjet shop, uses standard bicycle parts, and ships flat.
A sealed, swappable phase-change thermal cartridge in a few standard temperature ranges (cold chain, comfort and hot holding) that stores heat or cold and drops into coolers, cabinets and heat exchangers.
Walk-in evaporative cooling chamber with a solar fan that forces air through a wetted pad, and a controller that responds to humidity.
An open battery management board for small LiFePO4 packs (4 to 16 cells) with cell balancing, protection and a documented state-of-charge estimate, reusable across the lab's vehicles, storage and field kits.
Retrofit kit that turns a manual pallet jack into a powered, walk-behind unit with a UWB follow-me mode and layered stopping.
A curbside loading bay occupancy sensor that shows delivery drivers which bays are free and gives cities data on curb use.
A well and borehole water level logger with a submersible pressure sensor and FieldNode telemetry, showing seasonal drawdown so communities can manage shared groundwater.
An acoustic leak sensor that clamps onto water mains and valves and listens overnight for the noise signature of leaks.
Walking-treadmill vehicle: the rider stands upright and walks at a normal pace on a short free-running belt between the wheels, a belt-speed sensor sets the assist of a 250 W hub motor, and the vehicle moves at e-bike speed (up to 25 km/h) on a shared SwapCell pack. Walking is the control input; the motor does the work.
Motor-assisted hand truck on tri-star wheel clusters that climb stairs one step at a time, with a tilt sensor that helps the courier hold the load angle steady.
Wrist-worn IMU band that logs tremor frequency and amplitude continuously, with an open analysis notebook that produces a daily tremor profile.
A solar-powered, weatherproof sensor node with a common mounting, power and radio core, so any lab project that needs to measure something outdoors starts from the same tested base instead of a new enclosure and charger each time.
Inline UV-C LED reactor with a flow-activated switch and a dose monitor, sized for a household tap.
Open, bolt-on electric conversion kit for existing steel bicycles, serviceable by local bike mechanics and charged from a single 100 W solar panel or a shared village hub, using a SwapCell-compatible battery.
Pressure-sensing insole that detects the onset of a freeze and triggers a rhythmic haptic or audio cue.
A hydrogen leak detector and ventilation interlock for small labs, workshops and electrolyzer rooms: it senses hydrogen near the ceiling, runs a fan and cuts the supply when readings rise.
A clip-on monitor for older machines: current clamp, vibration and temperature sensors report run time, load and early fault signs from lathes, pumps and compressors that have no electronics of their own.
A sound level meter node that records decibel levels only, never audio, to map traffic and nightlife noise.
A solar crossing beacon that detects a waiting pedestrian and flashes high-visibility lights to warn drivers at unsignalized crossings near schools and markets.
Roof-edge sensor mast that detects ember showers with IR and wind data and triggers a gutter and eave sprinkler zone.
