Check out this really cool DIY on how to make a vertical wind turbine.  This thing can produce some good amount of electricity for under $300.

With this one I am hoping to get the 100 watts.

Here is how I did it.

First we need:
–5 pvc tube. size 3″X10′ (hardware store)$48

–3 bike wheels. size 12″ (junk yard or ask your kid to use their bikes for a minute) maybe $5

–Ametek38 volt (ebay or surplus store) $60 (a problem with ametek, it needs 700 rpm to reach 14.1volt.

–Or buy windblue alternator (ebay) $250 it will only need 200prm to reach 14.1 volt

–1 square foot 1″ plywood or anything 12″ diameter (laying around)

– 3 X 2×4 X 12′ studs (from lumber store)$11

I am not going to name the tools, but I used the usual tools.

Don’t mind the post title as this DIY shows you how to make hydroponics unit for growing anything.

Aside from people with medical marijuana licenses who live in San Francisco and can legally grow several pot plants, the hydroponic system can be used for growing your own organic vegetables and what not.

My wife teaches 8th grade science. This project “The Hydroshack” is a rendition of one I built over 20 years ago in my college teaching methods class. It is designed specifically for performing experiments in a science class. It therefore incorporates some modifications for flexibility and control purposes. It also needs to be collapsible for storage in tight quarters. If you are considering building something similar for your home, it can be less complex.

Of course, if you don’t want to build one yourself, here’s some resources too:

Hydroponics.com sells bunch of nutrients and other hardware needed for home-growing.

All about Hydroponics at Wikipedia.

Hydroponics.net sells bunch of stuff for home-growing too.

Here’s a fun DIY on how to make a chapstick LED flashlight.  It’s pretty simple to do but a great idea.  Maybe Chapstick companies will pick up on this and make them as promotion materials.

This is an instructable on how to make a flashlight out of a ChapStick tube. After reading up on multiple LED instructables I thought it would be neat to make an original design that had not been done before. Since button cell batteries can be expensive, I went with an A23 (12V) battery that cost less than $2.00 for two.

Here’s a cool instructables on how to make a fakeout stereo face to deter thieves from stealing your precious stereo face.

This faceplate is made using the original Delco radio/cassette tape player that came with the truck, some Velcro, and a lot of epoxy glue. I left half of a cassette sticking out of the tape player for added effect.

Here’s a great DIY on how to make Ping Pong Lights!  Actually, the “idea” or the “concept” is very creative.

At some point last semester I realized that ping pong balls make great diffusers and look really cool when they are glowing. Next we concluded that a hundred glowing ping pong balls would look even cooler. It was at about this point I decided that my apartment was in dire need of some ping pong ball lights.

Wow wee, this is an awesome DIY 56 inch multi-touch television!

I have built a nice multitouch display during my spare time as a hobby. In this article, I will share plans and explain how to construct a 56 inch multitouch screen that looks like a TV. It’s totaly homemade, it’s not made from an old tv but you could do so. This article is for people who already have basis in this kind of thing. It’s not an easy setup and it’s not suitable to be commercialized but for personal use it’s fine to test new soft.
