Khattak's Laminar Flow Nozzle Project

Post  Khalid on Fri Jun 10, 2011 10:49 pm

Hi,
Here is my Laminar nozzle with 6 inch Diameter pipe. I have to add a Pre-filter with 4" Diameter pipe so that i only have to clean that and not disassembling of complete nozzle. Cutter and RGB lighting is still in progress.
The nozzle is connected to tap water with low pressure so the laminar arc is small... Actual arc is 5.8 feet high and almost 12feet long.

Very neat, the nozzle design is interesting, how does that work, with the top plate standing up like that?

The arc is quite small, can it go any further?

Hi Pete,
The top two 3mm Plates is for cutter arrangement. I will place a 2.5mm plate as a cutter between these two plates. The middle plate will be connected to the solenoid.
The Nozzle is connected to Low pressure Tap water so the arc seems small.. I have tested this design with high pressure and the Arc maximum height comes 5.8 feet and the length about 12feet...

We do not need expensive Anemometer- Just a DC Motor

Post  Khalid on Wed Jun 15, 2011 8:12 am

Hi,
I have made a small wind sensor from a DC motor of old CD ROM. This DC Motor 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.

Soon will post the video:)

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

The difficult part is cutter mechanism...here is my second successful attempt of making the cutter:

Today i have not experimented on the laminar flow nozzle but just drew the circuit for the project. This circuit is based on ATMEL A328 and can control RGB LED, High power devices like Pump(220V AC), Anemometer, temperature sensor. 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)

The circuit with all component cost me around 15 US Dollars.

Truly amazing... I wouldn't know where to even begin... I wish someone would offer items for sale - being the worldwideweb its not that was easy, but when something works - other will buy it. I could have turned my own nozzles, but John made it so easy just to buy from him. It helps get the project pumping that much sooner. Example: this cutter. This cutter (I have not seen it in action) could be added to 'most' .5" nozzles and its simple to control = I would buy 1 or 2 of them.... At the same time, I respect can someone who has these skills and doesnt have the time or care to sell in small units.

Cant wait to see this come to life!! Very Happy

Hi gator,
I know how difficult and perplexing is when either we have no resources in surroundings to DIY or no knowledge how to DIY. One more thing is non-availability of ready-made things or if available that costs too much:(
Yesterday i have installed the anemometer. Here is the video:)

your cutter

Post  JohnJarvis on Fri Jun 24, 2011 1:47 pm

Hi, I think your cutter design is excellent. Any chance of a video with it in action with the working nozzle?

Nope... No video yet... I am busy in following:

1- just ordered 3 watt RGB LED from dealextreme website and PMMA end glow cable and waiting.
2- My controller is completed however the enclosure is still has to be completed.
3- I have a digging/installation activity in my Garden in the coming days.

Cut the drums half but they loose the strength and buldges.. So made a strip to reinforce it. It is not my idea but got from the old Wine storage wooden drums
Also purchased the pump and tested ..working fine

Here is the cost:
220VAC Pump Qty:01 = £33 (US $52)
Drums Qty:02Ea : Free from scrap yard
Drum reinforcements: £5.63 (US $9)
wire meshes and installation on other half drums: £13 (US $21)
Foam : £1.88 (US $3)
RGB LED's Qty: 05 ea (Only one shall be used in this project) : US $13.19
PMMA cable (total 30 Ft) 3ft shall be used in this project: £25 (US $40)
CPU processor heatsink with fan( shall be used as LED heat sink) : £ 1.88 (US $ 3)
Controller card with All Accessories: £ 8.14 (US $ 13)
Shall include the cost of digging/installation of the whole system
shall include the cost of making one Laminar flow nozzle

and the pump:

The rings are a nice touch and good thinking to keep the overall shape... This is looking great!!

Thanks Gator:)
Today i received the fiber optic cable34 feet long US $44.71+US$ 6.95 Shipment charges.Another good news is my other drums are ready with double mesh. The mesh is necessary not to spread the falling water. I tested and the mesh did a magic.Tomorrow the digging/plumbing work shall be started. I think it shall be finish in two days. I will post the pictures.
3 watt LED from dealextreme is still on the way.

Actually i am installing two laminar fountains at different locations. Here is some updates of digging work.
