We are designing things that help people with physical challenges and limited movement including L.I.S ( Locked in syndrome)
We need a basic sound module.
Think of it like a really basic e drum module.
It will have 4 trigger/sensors (that we will provide)
It needs to play 4 .wave file sounds, one for each trigger sensor.
Like a drum module it needs 10 banks so the user can choose a set of 4 different sounds from each bank. L/R 1/4" outputs with a master volume control. It does not need a display to show the sounds or banks. A dial/knob will suffice.
We would like to add more features in the near future like sub out and usb custom sound input and more.
We need a prototype and files to make it PCB ready.
We do not need the enclosure or sensors, just the electronics.
Please provide any info on Pcb cost if possible.
