This Gadget Freak review looks at a cooler that is essentially a party on wheels. The Coolest Cooler has built-in blender, Bluetooth speaker, and USB charger. We also look at a sustainable, rotating wireless smartphone charger that can rotate 180 degrees and that you can use while it charges.

The vintage Gadget Freak is a DIY Flexible Display that shows a seven-digit display.

The Coolest Cooler

The 60-quart Coolest Cooler is packed with everything you need to have a good time outdoors, including a built-in ice-crushing blender; a waterproof, removable Bluetooth speaker; and waterproof USB charger. Other highlights include an LED lid light so you can check out what is in your cooler at night, and a bottle opener.

The cooler opens like a picnic basket so you will be able to travel with your essentials, and the split lid opens to a removable divider. On the top of the lids you have storage for the four plates/cutting board and the ceramic knife that comes with the cooler. Traveling with the cooler is a breeze -- the wide wheels allow it to easily roll over sand and the bungee gear tie down allows you to secure items to the top.

The Coolest Cooler still has a month to go on Kickstarter and has raised almost seven million dollars of its $50,000 goal. With a pledge of $185, you can be the proud owner of the Coolest Cooler. It is expected to ship February 2015.

Sustainable, Rotating Wireless Smartphone Charger

Switch, a smartphone wireless charger, is made from sustainable materials and is designed to adapt to screen rotation needs. Many flat charging pads, stands, or holders do not allow you to use your device, but the Switch was designed to charge and offer a "viewer friendly angle" so you can use the screen and buttons while it is charging. The phone can be rotated 180 degrees so you can use your phone horizontally or vertically.

Switch was designed to be as natural as possible so it is made of fine ceramics and American walnut. A micro suction surface is used to keep the phone in place on the charger.

There is still time to pledge money to this Kickstarter project. Shipping is expected to begin in November.

Gadget Freak Rewind: DIY Flexible Display

Flexible displays are a hot topic, and Marin Davide's goal was to find a cheap and easy way to build one at home. Normally, flexible displays refer to Oled or E Ink, but Davide created a working prototype of a flexible display that can be built at home without special equipment.

The prototype shows a seven-digit display, but this guide can be easily modified to make a small dot-matrix display. The working prototype uses a sheet material printed with thermochromic liquid crystal ink. It changes color (bright blue) when heated above 27C. Nickel-chrome wire is used to heat the segments, and everything is controlled by an Arduino Mega board.
