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.

Concorde may be one of the fastest airplanes that most of us will ever ride in our lifetime and someone has made a 1:1 real life-size replica of the Concorde engine using what he learned from a $10 Concorde engine repair book he bought on eBay.

This engine might not run but I am sure the guy who made it knows almost every detail of what went into making the Concorde engine.

Design firm PostlerFerguson has created Olympus, a 1:1 model of one of Concorde’s engines, which will be on display in the window of Selfridges until October 22.

How about some authentic crocodile-skin gym bag that costs $13,800?  If you are gym-fanatic, this might suit you well for years to come and you can look “rich”.  Did we mention that you could get a cheap $5 bag on eBay, get 1 year membership at your local fitness center (around $1000 to $2000 per year), AND you could probably afford a used Mini Cooper if you decided not to get one? Well, probably a really really old and beat-up Mini that is…)

If you were born rich and you still are, we do recommend you get this bag and send us some pics.

The bag costs more than many cars and is made from extra-soft, oil-tanned and waxed Nile crocodile skins. The insides are made of pinstripe silk and you can shut the bag with an antique silver zipper. With a size of 12″ x 19″ x 10″, you could stuff in almost anything you want and still look stylish and chic. The Tumbled Croc Bel Air Gym Bag costs $13,800.

Well, it took me all day to get all my sites running today, there’s was a massive DoS attack by some hackers I had to take care of.

With that cleared away, here’s how to make some inexpensive solar cell panels.

Mike Davis is an astronomer. To practice his hobby away from the light-pollution of cities, he bought some land in a remote part of Arizona. But there was a problem: No electricity…. But he’s a resourceful fellow. He built some home-made solar panels using inexpensive blemished and damaged solar cells from eBay!

How about one of these life-size Terminators in your home? (I bet Governor Schwarzenegger has a bunch of these in his house)

This thing is over 6 feet tall and may cause “fears” at night while you walk in the dark for a scoop of icecream.

There’s a Buy-It-Now price tag of $19,999.99.  I don’t think it’s worth that much but if you really need one, go knock yourself out.

With a 6-foot structure, the T-800 can sometimes be a pain if you have to carry it around. Fret not, because it can be dismantled and assembled with ease. It is fabricated with chromed metal, fiberglass and an assortment of other materials that add to its overall appeal.

DIY - How to Build a Traffic Cone Lamp!

Traffic Cone Lamp seems like a such a great idea for making traffic cones safer in general by contractors and alike who use them on a daily basis.

In case you want to just make a Traffic Cone Lamp for your garage, here’s how to do it.

Cones are available on eBay for cheap, but the shipping can be a bit much. Orphan cones are a dime a dozen in cities, but often too dirty and messed up to use. Please don’t steal them from active job sites, because they are safety equipment for someone. Other good places to check are auto salvage yards and the county/municipal dump, because that’s where the local government takes their bulk waste.

My cone is 28″ tall and 14-3/4″ square at the base, and weighed about eight pounds before the lamp parts were added. They come in all different sizes, and you could even make a desktop one out a of a little tiny cone. I used a 75-watt equivalent compact fluorescent. A brighter fixture could eliminate the need for the holes. Do not use conventional bulbs; they get hot enough to damage/burn/melt the cone if there’s nowhere for the heat to escape.

Here’s a really cool DIY showing you how to build a hard disk laser scanner made from bunch of old hard disks.

My latest tinkery hardware and embedded systems project is a homebrew laser scanner. You know, the kind you see at planetariums- sweep a laser beam around on the wall really fast, and draw vector graphics. Commercial laser scanners have been around for decades now, but buying a complete system is still really pricy, even on eBay. Besides, where’s the fun in that?

There are plenty of examples of homebrew laser scanners on the internet. Many people have wired up a pair of loudspeakers, hard disk actuators, or other readily available mechanisms to an amplifier and used them for simple laser graphics. This will make some pretty wiggly patterns on the wall, but it isn’t a real vector graphics display. The best example I know of for a totally built-from-scratch laser projector (not using commercial galvo actuators) actually uses custom hand-wound galvanometers. Very nice.
