Back at CES in January, TechCrunch met Fin, the Bluetooth ring that went on to become one of our Hardware Battlefield finalists. Fin, which turns your hand into a wireless controller for smartphones, TVs, and other connected devices, is now just a few hundred dollars short of its Indiegogo goal. To be sure, Fin has a flexible funding campaign, which means it will receive all money raised even if it doesn't hit its target amount. But if Fin reaches its stretch goal of $150,000, it will be able to make the ring available for a discounted price to visually impaired people.
