Sonic Massage Parker IoT Compressor Update with part list! LSM9DS1 IMU for vibration sensing iNEMO inertial module: 3D accelerometer, 3D gyroscope, 3D magnetometer 3.3V, I2C SPU0410HR5H-PB MEMS Microphone 3.3V Analog signal, will be boosted with an opamp TMP102 Board Mount Temperature Sensors Low Power Digital Temp Sensor 3.3V, I2C PX3AN2BS250PAAAX Pressure Transducer 1/8" NPT Male fitting 5.0V Analog output 0.5V - 4.5V over pressure range 6225AXXSZS-DC3 SSR to control the compressor switch 3VDC to 32VDC control signal Place 10ohm in series from pin from particle photon for protection. Stephen Voltage Standard Calibrated complete! Used the Keithley DMM7510 to dial in the voltage standard. Synth Update: Now with sound effects!   Stephen played a bunch of warbles Only one section is working at the moment - VCO - voltage controlled oscillator Space Echo is now working Mechanical adjustments are calibration to! Break the tape in to let it run, the sound gets better. Pick
