Each week, our friends at Backerjack bring us updates on some of the most successful gadget crowdfunding campaigns.

ADEL

The increasing number of both teens and adults with mild to severe hearing loss caught audio legend Stephen D. Ambrose’s attention and he, along with his company Asius Technologies, created RealLoud Technology. In turn, they’ve created earbuds that cut down on the detrimental effects of loud noises in the ear, ADEL. The tech reduces harmful pressure experienced by wearing ordinary headphones using bio-mimicry, or the imitation of nature through technology, to include a built-in secondary eardrum to absorb them for you. As a result, louder, more complete sound is produced by eliminating the pressures associated with unnecessary noise, even if actual volume is technically quieter overall. This is the crux of the RealLoud Technology, and the key behind the entire series of 1964|ADEL headphones.

Backers are stoked about this product, helping the company raise twice its large original goal. The total money donated to this project now exceeds $400,000.

Eva

Eva

Many parts of the world are experiencing the most debilitating water crises in recent history, slowly increasing the demand for water as time goes on. Perhaps most people don’t talk about it because they don’t feel like much can be done. For this reason, the creators give you the chance to play your part with the Eva Smart Shower.

Eva connects to most standard shower heads and facilitates your showering experience, cutting down on water waste. An onboard temperature sensor cuts water flow when it’s reached your desired temperature, starting up again when you enter, and a motion sensor throttles water according to your distance from the shower head itself. A companion app interacts with the Eva, allowing you to set your desired temperature and manage shower length goals, and it tracks overall water usage so that you can adjust your habits.

Becoming just a bit more eco-friendly requires information to make decisions and Eva provides. It’s a promising use of technology that should become widespread. Backers have supported this project almost to completion. They need just a few more supporters to reach their goal.

BitBite

BitBite

Maintaining a diet can be an extremely difficult test of willpower. A helpful companion, like the BitBite, can be a huge help in changing damaging habits.The BitBite is a wearable placed on the ear to monitor your chews. The hybrid Bluetooth headset is compatible with iOS and Android, and is voice-activated so you can tell it what you’re about it to eat. When that’s done, the device tracks the number of bites you’ve taken along with the pace of your meals. By combining all of that information, your dietary habits are gleaned so as to improve it on the fly with real-time suggestions. Not getting enough calcium? It’ll suggest you eat a yogurt instead of that donut you’re craving. Backers clearly want to lose weight because this product is within reach of meeting their $60,000 goal.
