Awesome tech you can’t buy yet: Mesh antennas, portable AC, and more

At any given moment, there are approximately a zillion crowdfunding campaigns on the web. Take a stroll through Kickstarter or Indiegogo and you’ll find no shortage of weird, useless, and downright stupid projects out there, alongside some real gems. In this column, we cut through the worthless wearables and Oculus Rift ripoffs to round up the week’s most unusual, ambitious, and exciting projects. But don’t grab your wallet just yet. Keep in mind that even the most well-intentioned crowdfunded project can fail. Do your homework before cutting a check for the gadget of your dreams.

goTenna Mesh — Off-grid message communicator

Smartphones have been a revolution in personal communications, but as advanced as they may be, they are still limited by the range and distribution of cell towers. If you are in an area with poor service (or even none whatsoever), you may as well try smoke signals to communicate. The team behind the goTenna Mesh hope to fix this problem with their device, which functions as a portable radio relay for phones.

Users connect their phone to the device using Bluetooth. When someone sends a message, the GoTenna Mesh broadcasts it through a UHF radio transmitter. The message will bounce to other nearby Mesh units until it reaches its destination; for the sake of privacy, the people functioning as relay points will not be able to see the messages. Of course, this system depends on people nearby having their own goTenna Mesh. As such, the company plans to sell them in pairs, so groups of friends traveling or going into the wild together will be able to connect.

Croz — DIY digital camera

Many people who have held a high-end camera, digital or otherwise, may have been perplexed by the many buttons and dials at their fingertips. Photography can be a dense hobby, and even as smartphones have made it more accessible, burgeoning shutterbugs may still fret over what filters or contrast levels to use in their photos. Lomography was developed to smash preconceptions about photography, encouraging users to take spontaneous photos with simple devices, focusing on the beauty of natural, everyday circumstances rather than carefully composed scenes.

The Croz digital lomo camera embraces this ethos, offering users a simple, two-button camera in a minimalist frame. Although digital, the camera uses a direct viewfinder, so there is no fiddling with distance; simply point and shoot. The camera itself is a work of art, available in cases made from various woods such as European ash and North American black walnut. The camera has a Micro USB port and can support 32GB SD cards.

EarDial — Smart earplugs

Live music is thrilling, at least until you leave the concert after two hours and hear that ringing in your ears. While tinnitus does not always cause serious harm, that ringing can sometimes be a prelude to permanent hearing damage. Given how many concerts and clubs have music playing well above safe levels, earplugs are a necessity to prevent hearing loss, but many of them can be ugly, or make it difficult to hear the world around you.

EarDials are a pair of smart earplugs, designed to fit comfortably and stealthily in your ears, filtering out harmful noise without blocking all sound. Made of transparent silicone, the earplugs blend in with the your skin, and are soft enough for extended use. The makers of EarDial claim that the plugs contain a high-fidelity noise filter that will keep out harmful levels of noise while letting you hear clearly. The device also comes with a companion app for smartphones that will give you a decibel rating for the noise around you.
