Baby Cry No More (tm)
This product utilizes a mechanical device to produce a motion similar to a mother patting her child. The device contains a sound module subsystem that plays a soothing version of Brahms's Lullaby. I was contracted to develop a sound subsystem (subsystem) by the engineering firm that was developing the microcontroller main board and mechanism. The requirement was a "plug and play" component for the main board. The device required high-quality sound and a special requirement of a dual-channel sound device. This product is in production and will be available early this spring.
