16 mm Projector: It was the first major design project from Industry for IDC. The original design was from RCA(Radio Corporation of America), an American company. Photophone pvt ltd, the Indian company had bought the moulds to make the projector. 4 die-cast aluminum parts with several inserts formed the core of the 16mm film projector. The old design had several short comings.The additional castings brought in ‘visual binding’ to operating knobs, in addition to giving a functional advantage to take both spools to the top. The colour scheme ensured this visual organisation. Use of small halogen lamp reduced visual domination of lamp cover. Control knobs acquired a visual space. The controls for projection and Sound got segregated with colour coding. Vacuum formed covers in ABS plastic gave a new identity of a precision instrument to the projector and sound box. Additional castings one for the base and other at the top for spools were made in gravity die casting out of aluminum.Speaker Box Sizes of the Speaker box cover and Projector cover were kept same. This facilitated use of same basic moulds for vacuum forming. A cut out in the front gave opening for the speaker. In the back side cover of the ‘speaker box’ a compartment with a hinged cover was introduced to store the connection wires. Voltage Regulator Standard Voltage regulater was redesigned to give a comaptible as well as exclusive look.
