A series of connections of photodiodes has a plurality of alternating N-type conductivity surface areas with P-type conductivity surface areas with each member of the P-type conductivity surface areas being separated by a member of N-type conductivity surface areas. The sensors operate with a low voltage non-rechargeable battery and are fully functional for at least about 15-20 years. The tuner also includes a selectable and integrated low noise amplifier that may be selected for single-signal reception and bypassed for multi-signal reception. The system also includes a projector projecting a video stream onto the gas bubbles based on the location, shape, and size of the area of the liquid surface containing the gas bubbles.
