The kickass sci-fi gadgets you can build yourself

This kind of electrical coil which shoots up huge volt of blue electrical charges is named after scientific inventor, electrical engineer Nikola Tesla who has huge contributions in the field of electromagnetism. This kind of coil is seen in the sci-fi movies like The Prestiege and heard of in novels like Frankenstein. Now, one can build Tesla Coil easily by means of metal plates, bolts, brackets etc. This things you can find easily in a hardware store. You have to find a transformer also which has a capacity of 9,000 or more volts and 30 milliamps. But always remain very careful because it can give shock which is fatal.

Laser weapons are very staple things of sci-fi movies or books which have intergalactic type of war. Apart from intergalactic war, use of laser weaponry is also seen in comics and movies of Iron Man. Now, if someone wants to build a cheap laser weapon, he or she has to derive a laser diode from some DVD or Blu-ray or PS. Then along with a diode housing, 9-volt battery, some glue, a screwdriver, a small sharp knife, wire, wire snips, vice etc., and a little bit of electrical knowledge one can build this easily and cheaply. Though this type of household laser beam producing objects cannot blow things or men up, still these are capable enough to light a candle, blow holes in woods or burn at least a small area of skin as well.

Of all household sci-fi gadgets, this jet pack rocket thing costs a little bit more money than others. Of course, the builder has to have a sound knowledge of building mechanical things and rockets. Moreover, a tank full of a peroxide hydrogen will help the builder fly. The whole thing can be built just below $10,000. But building this sort of household thing which can take a man out in the sky always involves some sort of danger.

Rail gun is an Earth bound sci-fi concept weapon where an electrical gun which is on two parallel rails shoots electrical pulses at great speed. All these things need a pair of rails, coils, armature, electric connections. It is heard that US army is building its own such huge rail gun. Since that type cannot be made in a normal house, things like some wires, batteries and capacitors can help a builder to build a mini rail gun in house quite easily and cheaply.

Exo suits are not exactly space suits kind of thing which astronauts wear when they are in space. These exo suits are some techo-suit type of things which help user do heavy duty jobs in outer space or large techno environment.

In many small scale exhibitions and scientific-talent hunt competitions, gadgets freaks are seen to have built techno-exo-suits out of ordinary and easily found materials like chrome-myolybdenum steel alloy, big twisted coils, armatures etc. These suits even perform quite successfully in lifting small but heavy objects. This kind of suits do not cost more than $1,000 or 2,000.
