Rotary sprinklers are used all over the world, for watering lawns and gardens. They are easy to see in daytime but a trap for the unwary, at night.
The Night Sprinkler has a small hydroelectric powerplant built into the spindle assembly, generating enough charge to run a few high intensity LEDs.
A simple rotary switch and some gearing and different coloured LEDs are illuminated in a slow sequence, making a dazzling nighttime water feature of your lawn sprinkler.
Tiny, sparkling diamonds of light, showering your lawns in brilliant colours, whilst rehydrating your plush, emerald carpet of bentgrass or couch! You'll never walk through a sprinkler in the dark, again.

so simple you wonder why it hasn't already been done. |
|
| |
It would be pretty easy to make. |
|
| |
sounds like a challenge.. |
|
| |
sometimes it gets dark early ? |
|
| |
[Z] Use of sprinklers (and any other automated watering system) currently a no-no due to water restrictions in my neck of the woods, I'm going to have to move so I can use this. + |
|
| |
No restrictions here. The reservoirs overflowed, leaving us 7 years reserve. |
|
| |
I'll just affix the hydroelectric powerplant to the nozzle of my hose and twirl myself around... will that generate the necessary charge? |
|
| |
I presume there would be a greater charge if you left the hose unattended and a water inspector chanced by your premises? |
|

//I thought you were not suppposed to water at night...//
There may be legal restrictions I am not aware of, but for practical reasons watering at night is actually preferred. In the cooler night hours, there is less evaporation and therefore less waste. If your local utility bills use based on time-of-day, perhaps to manage demand, water might be cheaper at night. |

I think light will only travel down a stream of water if it remains unbroken (not seperated into droplets), so I'm not sure how colorful this would turn out to be. But I could be wrong... |
|
| |
If I had a lawn, I'd get this just for the light show. |
|
| |
Watering at night is generally bad for plants, though. Mildew. Early morning is the best. |
|
| |
The resistance will cut out on the radius of the spray. But, its a small price to pay for dry burglars... Seriously, though, good idea! |
|
| |
Watering at night is not as much of a problem in locales where the temperature can be 90 degrees at sunrise. Water, however, is a different matter. |
|
| |
Watering at night in locales that are at all humane or desirable to live in is a bad thing for plants. |
|
| |
I'm for twilite showering! I think I'll just drag my sprinkler into the bathroom and let the lawn burn. |
|
| |
all you really have to do is shine a light through the bottom of the sprinkler, like they do with those fancy water fountains at resturaunts. |
|
| |
Yep. Makes you wonder why you can't get one, right? |
