A new edition of The Hacklet is now available It covers some of our favorite stuff going on in the Hackaday Projects community.

In this edition, we round up a few hacks involving cars. There’s Bluetooth Low Energy connectivity, vehicle telematics, and tools to hack into your car’s CAN bus. If you’ve ever wanted to clear that pesky check engine light without paying the dealer, or unlock your car with a smart watch, these are worth a look.

Next up are a bunch of LED hacks. This starts with a DIY theater light, then looks at a portable DJ booth, finishing off with our Evil Overlords’ own LED visualization platform.

Finally, we check out a new 3D printer design. This one uses polar coordinates instead of the Cartesian coordinate system that most printers use. This gives it the unique ability to print with multiple extruders at the same time.

Once again, let us know what you think of this edition in the comments. Our goal is to keep you entertained with some of the coolest hacks on the site.
