Laminar Flow Nozzle- Update on DIY Anemometer

I installed the Anemometer and it is working quite well... Anemometer heart is a CDROM DC motor. It produces voltages when rotated by wind. these voltages are then fed to micro-controller to get the wind speed.
Here is the video:

Laminar Flow Nozzle- Automatic Control Unit

Today no experimentation was carried out on the laminar flow nozzle. My RGB LED's and Fiber Optic End Glow cable (PMMA) are on the way from European supplier.. I already have Solid State relay (DC-AC) to control 220 V AC pump. I drew the controller circuit for the project. This circuit is based on ATMEL A328 and can control 3Watt  RGB LED,  Pump(220V AC), my DIY Anemometer, temperature sensor, DIY soil moisture sensor, 24V Solenoid cutter mechanism. I have added one shift register 74HC595 so that i can use the 8 output to control the lighting of surroundings... (The resistances have yet to be calculated after arrival of the LEDs)

Laminar Flow Nozzle- 2nd but Successfull Cutter Attempt

The difficult part is cutter is my second successful attempt of making the cutter:)

Laminar Flow Nozzle Updates- Cutter mechanism, Pre-Filtration Unit and modified Anemometer

Here is the Cutter mechanism with 12 V Solenoid. Also you can see Pre-Filtration Unit...and a painted modified anemometer...

DIY Anemometer- Sensor for Laminar Flow Fountain Control at High wind

I have made a small wind sensor from a DC motor of old CD ROM. This DC Motor does generate 0.3V at high wind. So i have to use it for my Laminar Nozzle project. At low wind the voltage generated by the motor is little but if wind is on higher side a voltage of about 0.12 VDC the fountain stream can be disturbed.

Did a little programming in Arduino when a DC voltages reaches to 0.12Volts stop the fountain and when the voltage below this value ON the fountain... I know you people will understand.. this is not a real Anemometer but with wind it gives us a voltage reading which we can use to start or stop the fountain.

Updates on Laminar Flow Nozzle

Dear readers,
Been involve in developing the garden in-front of my house. I am going to install laminar flow fountain their. I made this fountain from 6inch diameter 1foot length pipe. The stream seems to me a perfect laminar. you can see how crystal clear it is.
I have to install RGB lighting and cutter mechanism. A good micro-controller programming will reveal millions of colours in this fountain.

and here a small video clip. Actually the Nozzle is connected to low pressure tap water, therefore the laminar Arc is small. I have to make a small pond with pump that will give this fountain a real life.
