SolarPack turns an everyday backpack into a portable power station. Three magnetic solar panels clip onto the front and can be swapped or stacked depending on the trip — all three for a multi-day hike, or just one for a daily commute. Every strap, buckle, and panel is designed to be replaced individually, so a torn strap never means buying a new bag.

The full CAD files, panel wiring diagrams, and bill of materials are open for any builder to fork or improve. Community submissions have already refined the panel mounting system twice since the project launched.

OpenVolt is a battery pack built around one idea: nothing inside it should ever be un-repairable. The cell trays pop out individually, the fast-charge controller is socketed instead of soldered in, and every part is on the open BOM so a burned-out cell doesn't mean the whole pack goes in a landfill.

It's already funded past its original goal and is moving into its first manufacturing run. Builders have contributed two firmware revisions since launch, including a safer thermal-cutoff profile that's now the shipping default.

GraspAgain is a 3D-printable, sensor-driven adaptive grip attachment built around one core idea: kids outgrow adaptive tools fast, and replacements shouldn't cost thousands of dollars each time. Every part can be reprinted and resized locally as a child grows, using open files and widely available filament.

The project is still early — the community is actively voting on grip-sensor submissions this month to finalize the next revision.

CompostIQ is a smart compost bin that tracks internal moisture and temperature and tells you exactly when to turn the pile — no more guessing, no more smell. The sensor module and companion app are both open, so builders have already contributed three regional composting profiles tuned for different climates.

A finished unit is expected to reach backers once the current manufacturing round wraps.

MeshRelief is an open mesh-radio network built for the moment cell towers go down. Each unit relays messages to the next, building a resilient local network across a neighborhood or town without needing central infrastructure — designed for disaster response teams and communities in hard-to-reach areas.

This one's early and needs backers to reach the prototyping stage. The core radio firmware is already functional; the community is now voting on enclosure designs submitted this week.

AquaClear is a gravity-fed water filter built from off-the-shelf parts, designed around one rule: every replaceable part has to be buyable at a normal hardware store. No proprietary cartridges, no subscription refills.

It's overfunded well past its original goal, and that extra funding is going toward a larger first production run and a Spanish-language install guide. The full filtration-stage design and maintenance schedule are open, so any community running one can service it themselves.

LoopBuds pair a standard telecoil hearing-loop receiver with a fully open, repairable earbud shell — battery, driver, and receiver module all replaceable on their own. The goal is a pair that costs a fraction of proprietary hearing-loop hardware and lasts a decade instead of two years.

The core electronics are stable; most of the open work right now is in fit and comfort — the community is voting on two competing shell geometries submitted this month.

WindNest is a quiet, rooftop-mountable micro wind turbine, sized for a single home and simple enough to install without a specialist crew. It just launched, and it's very early — the core rotor design is posted, but the project needs its first wave of backers and builder submissions to move toward a working prototype.

If that sounds like your kind of project, this is exactly the stage where an early submission can shape the whole design.
