  3. Fountain Layout Brass Water Nozzle … x16 … ½” O.D. Tubing WT170 Submersible Pump

  4. WT170 Submersible Pump • Water Flow: 170 GPH max, adjustable • Inexpensive, low power • Voltage: 120 VAC • Current: 195 mA • Power Usage: 12 W • 3 pin plug • Control AC signal to turn on and off.

  5. Controlling Power to Pump • Relay – SPST switch controlled by signal from processor • Isolation • PS710A-1A Optically coupled solid state relay

  6. 120 VAC 60 Hz Signal from processor x8 x8 Signal from processor

  7. Sonar Sensors • Can detect objects at a distance between 2 cm and 3m away from the sensor • Can use several of these to control various pumps or valves in the system

  8. Sonar Sensors How they work

  9. Sonar Sensors How they work

  10. Software

  11. Winamp Plug-in Board Winamp • Determine beats from music info • Perfect beat detection is difficult • Sends music info to board over serial Frequency range of various instruments

  12. FreeRTOS Serial Port Listener Sonar Listener Fountain & LED Control Winamp Fountain LEDs Sonar Sensors • Winamp/Serial port listener • Sonar listener • Fountain and LED control

  13. Electric Zen’s Development

  14. Milestone #1 Goals • Have one pump and one sonar being controlled with simple inputs from Demo Board • Software is ready for the pump and the sonar • One pump responding to Winamp plug-in • First revision of PCB complete, populated, and tested for functionality

  15. Milestone #2 Goals • Water fountain controlled by Winamp plug-in and sonars through circuitry on PCB. • All pumps respond to sonar and Winamp input • Water fountain structure complete and inside a completed plexiglass containment

  16. Parts List Grand Total $ 2482.00 Current Funds $ 1000.00

  17. Water Fountain and Beyond • Underwater Lighting • Proportional Valves • Outputting sound • Simultaneous sonar/music control
