Lights Adjustable
How can I project a sharp line of light on an object 2 feet away?
The light should be thin and preferbly adjustable in length and width.
The positive lens only gives me circular light not a vertical/hotizontal sharp beam. Also laser light is not useful for my purpose. There must be an appropriate appratus/method for this. Thanks for your valuable contributions.
My son has a cheap red laser pointer (well under $10)
which has a few "lenses" that he can screw on the
front to make different patterns.
I don't know if these things are strictly "lenses",
but they distort/focus/shape the laser dot to
look like a star, a line, or a couple of other
patterns.
In any case, one causes the laser pointer to produce a
"line" rather than a "dot", and that seems like it would
satisfy some of your needs. The width isn't readily
adjustable, but the the length would be (by covering
part of the "line" just past the light source).

Socket Adapters
Do MR16 to E27 light bulb socket adapters exist so that a regular light bulb can be put on MR16 halogen socket?
I moved into a new place and the light sockets in one of the rooms are strangely MR16 halogen ones. I hadn't even heard of them and was pretty disappointed to find out I couldn't use regular socket light bulbs with them.
Anyway, I'm not a big fan of halogen bulbs and they're really energy inefficient, so I would really like to be able to so use regular E27 CFLs in there, and so I did a little research online for adapters, but all I could find was E27 to MR16 ones, but not the opposite.
Does anyone know if an MR16 halogen socket to regular E27 socket exists and where I can get it, preferably online? Thanks!
No, the reason for that is voltages, the voltage can be stepped down but not up to the 110V of e27. You will have to change the sockets.

Hydroponics Advantages Disadvantages
About agriculture?? URGENT, 10 points to best answer!!!?
list advantages and disadvantages of hydroponics and aeroponics
Hydroponics
Hydroponics has taken plant cultivation to the next level. In fact, people who were never interested in gardening or growing plants are now doing so, simply because they are intrigued by the concept of growing plants without soil.
But, what are the advantages and the disadvantages of hydroponics cultivation?
Lets take a look at the advantages of growing plants using hydroponics cultivation technique. There are quite a few benefits that comes with growing plants in soilless culture like:
Less space required
Less growing time required
Labor and garden maintenance is reduced
Water conservation
Nutrients are recyclable
Save money by recycling nutrients
Pest, weed, and disease problems can be controlled easier
Plants grown hydroponically avoids soil borne pests
More control over the plants rooting environment (Easily manipulate the root zone's temperature, humidity, darkness, et).
Higher Yields
Although hydroponics is probably the future norm of plant cultivation, it still has its disadvantages, including:
High set up cost
Growers require skill and knowledge to maintain optimum production in commercial applications
Because each plant in a hydroponics system is sharing the exact same nutrient, diseases and pests can easily affect each plant.
Plants react quicker to changes in the environment, however, if this change is for the worst, plants will quickly react to it; showing signs of deficiency or trouble.
Hot weather and limited oxygenation may limit production, and can result in lost crops
As with most things, it's important to understand the advantages and disadvantages of hydroponics. This will allow you to make informed decisions on what application is "right" for your individual requirements.
Aeroponics
Aeroponics can limit disease transmission since plant-to-plant contact is reduced and each spray pulse can be sterile. In the case of soil, aggregate, or other media, disease can spread throughout the growth media, infecting many plants. In most greenhouses these solid media rsequire sterilization after each crop and, in many cases, they are simply discarded and replaced with fresh, certified sterile media. A distinct advantage of Aeroponic technology is that if a particular plant does become diseased, it can be quickly removed from the plant support structure without disrupting or infecting the other plants.
. Additionally, the nutrient solution throughput of each of the systems was estimated. shows how nutrient solution throughput in the Aeroponic system is moderate compare to that of conventional NFT and even the soil substrate technologies.
sorry Could'nt find the disadvantages. hope this helps
