A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.

The next big step after installing solar panels on your roof is to install big batteries in your garage. That way you can manage your power better and have plenty on hand during power outages. The slickest off-the-shelf solution is a Tesla Powerwall. The non-Tesla alternative we went with is about the same price ($12,000 per 13 kwh) and capacity, but with a slightly longer warranty. We installed two Franklin lithium iron phosphate batteries, the standard composition for homes. Instead of feeding our electrons back into the grid at a low price, we get to use all the energy we produce during evenings and nights, and for charging our electric car. And during storms, we keep the lights and refrigerators on. Franklin is a complicated system installed by pros. For the true do-it-yourselfer who wants the cheapest possible home battery system, go to BigBattery.com to get your gear. — KK
In 1987, my wife Carla and I launched Boing Boing, a zine exploring cyberpunk sci-fi, indie comics, and fascinating oddballs. It evolved into a blog with contributions from our journalist friends, covering technology, culture, politics, and wonderfully weird discoveries. After 20 years of increasing ad dependence, we're excited to offer an ad-free premium version that's so much cleaner. Recomendo readers get 25% off their first year – I hope you'll check it out! — MF

An artist I follow on Instagram is Andy Thomas. He creates these very whimsical, hard to explain animations of fantasy shapes. He says he does not use AI. They appear to be half biological, half algorithmic creations and are unlike anything I’ve seen. I like their energy. — KK
This titanium quick-release keychain is built like a tiny tank with a clever ball-bearing collar mechanism. I use it to separate my house key from a carabiner that's clipped to my shoulder bag. It takes deliberate action to detach (no accidental separations), yet disconnects smoothly when you want it to. Here's a photo so you can see how small it is. — MF
