Electronic coaster

An electronic coaster, configured to respond to pressure and sound;

• the electronic coaster comprising:
• a case, further comprising a flexible top;
• wherein the flexible top is configured to deflect upon receiving pressure on the flexible top;
• and
• a circuit board attached to the case and configured to receive power from a power source and an audio signal from an audio cable;
• wherein the circuit board is configured to engage a plurality of light emitting elements when pressure is applied to the flexible top and an audio signal is played through the circuit board;
• wherein the circuit board further comprises:
• a three way bandpass filter electrically coupled to a switching circuit and a power circuit;
• wherein the switching circuit further comprises pressure circuit that operates a variable resister within switching circuit;
• wherein the switching circuit is open when either there is insufficient pressure on a pressure sensor in the pressure circuit or there is an either no signal in a range in the three way bandpass filter.
