Vendors showed many wearable devices at the International CES expo, but the next big thing may just come from an enthusiast's garage. To find the next wearable hit, companies are turning to the community of individual tech makers, who have been hacking circuit boards for decades to make technology accessible. New development kits introduced at CES will give do-it-yourselfers the tools to develop and experiment with new types of wearable devices. Intel and Free scale introduced mini-computers that the companies hope will lead to the creation of wearable devices beyond the array of smart watches, smart glasses and fitness trackers that flooded the CES floor. The new computers are more like pint-sized versions of the popular US$25 Raspberry Pi computer, which has sold more than 2 million units. It's difficult to build all the cool wearable devices in a lab, and makers, fashion designers and others will make a big contribution, said Mike Bell, vice president and general manager of the New Devices Group at Intel.
