Google's Project Ara promises to make your mobile modular, but what if you don't want to replace your phone? Check out this modular smartphone case instead.
It's called nexpaq, and it lets you customise, enhance and add features to your smartphone by slotting in new modules to the case. At the moment, there are 12 modules available. Battery Power gives you 90 per cent more juice, so your phone's battery will last almost twice as long as usual. Amplified Speaker makes your phone louder, while Super LED Flashlight helps you see in the dark. SD Card Reader gives you more storage, and Temperature and Humidity measures how hot something is, so can help diagnose if you have a temperature, say.
Hotkeys lets you set up shortcuts so you can go to the calendar, say, at the touch of a button. USB Flash lets you swap files with people, and Air Quality analyses the air around you. Breathalyser tells you if you're safe to drive, Laser is a laser pointer, and Backup is a tiny, portable 64GB hard drive. Dummy fills any empty slots you have.
And that's your lot. Each has their own battery built in, so can extend the battery life of your phone.
It's nearing its $50,000 funding goal, and if successful, will ship in January next year (though some betas will go out in November).
