HP 50G Graphing Calculator by Wessman

HP-50G, designed by Tim Wessman, for rugged use in the field and is able to network with other devices in order to more efficiently store and transmit the calculations it makes for later use. Wessman’s impressive winning HP50G entry included detailed graphs and content on design, display, keyboard and interface, user programs, compatibility, communication, test mode and durability.

Tim Wessman was a junior at Brigham Young University in Utah was the first place winner at the University level of the contest his design to the Create-a-Calculator contest. Currently pursuing a degree in manufacturing engineering. Wessman is the recipient of a $4,000 scholarship and an HP 49g+ graphing calculator.

Some of that knowledge came from Wessman’s efforts to launch a new product for surveyors called the DC-49, an adaptation of an HP calculator into a data collector that allows surveyors to take measurements in the field and then interfaces with their computers to create maps. His company, Precision Surveying Solutions, touts the DC-49 as faster and cheaper than other devices in the market. He hopes to launch the product in late November.
