Prototyping and testing results in a list of change orders for final Implementation. Working in CAD, each part is detailed to include draft, add production tolerances, and is generally made ready for tooling and production. The SIERRA, while simple compared to many competitive units, is still a complex electromechanical device. As such a full range of parts were refined by the VIDAR engineering team. Internal electronics, electromechanicals and optics include custom PC boards, a lens, three mirrors, an array, stainless steel rollers, and film feed/drive mechanism. Electronics are housed in a stamped sheet metal case. Casework includes two injection molded ABS parts (front and back), and two stamped and painted sheet metal end plates. Feed and catch trays are nickel-plated wireform parts, as is the wall mount bracket. Vidar’s internal team members handle the vast majority of implementation tasks and rely on our team members/or spot problem solving and inputs on aesthetic implications of engineering and production tradeoffs.
