Q: I would like to make a LED circuit consisting of three wavelengths of 680nm (670 has been used), 730nm and 880nm. There has been research showing these wavelengths are very good at regenerating body tissue (skin, muscle and nerves). I want to make a headset to place over my ears in hope of regaining some of my hearing. I would like a list of parts and reliable source for purchasing good quality parts and a circuit diagram.
