Cars have problems, just like people do. Unlike us, though, your car can tell you exactly what’s wrong — if you have the right tool.

I love my AirPods, but I hate that they don’t fit right in my ears. They’re not designed to seal the ear canal, and therefore block external noise, but they often sit so loose in my ears that a) I can’t hear them without setting the volume way too high, and b) they feel like they’re about to fall out.

Today we’ll see how to add grippy dots to your AirPods. These dots will make the AirPods fit snugly in your ears, but — crucially — they will still fit in their charging case.

Scotty Allen’s iPhone 7 battery was dying and, as you’d expect, Allen didn’t do the easy thing.

Rather than pay Apple to replace the battery or just get a new iPhone, the host of the YouTube show Strange Parts went on a vendor-to-vendor hunt in the electronics district in Shenzhen, China in search of a replacement battery.

If you’ve got the itch to make things, you probably already know about Arduino. It’s the platform for building all kinds of computer-connected gizmos.

Basically, if you can imagine it, you can make it with Arduino — and books from Make show you how.

With Arduino, it’s possible to build almost anything you can imagine. Whether it’s wearables, apps, or robots, the freedom Arduino offers can be liberating or intimidating, depending on your skill level. So this bundle of parts and lessons is a great resource for anyone looking to break into Arduino.

When Raspberry Pi rolled out in 2012, people immediately hailed the low-cost, credit card-size microcomputer as a fun new toy for kids and tech tinkerers. Since then, forward-thinking Pi users adapted this “toy” into a surprisingly powerful piece of tech. Users create everything from home media networks to robotics to fully automatic timesavers.

Commercial photographer Paul Adshead could have spent a few bucks for a macro lens attachment for his iPhone. Instead, a MacGyver-type of a hack gave him a lens and ethereal macro photos that seem achievable with only a high-powered microscope.

Feeling adventurous and uninspired by his smartphone photos, Adshead harvested an internal lens from a 1990s-era CD drive and, with a little tack-it putty, affixed it to his iPhone.

Arduino offers tools to build basically anything imaginable, from robots, to computers, games, weather stations, you name it. The possibilities are so vast, it can be hard to know where to start. So this bundle of Arduino lessons and materials offers a great resource.

Raspberry Pi is the platform for almost any DIY computing project you can imagine. From home entertainment systems, to robotics, to building your own smart home, it’s a compact processor with vast possibilities. So where do you even begin?

Raspberry Pi is a nearly limitless platform for all kinds of projects. It’s also a great way to bridge the physical and digital worlds, and a window into the internet of things. But to do that, you need the right gear and guidance.
