How do I make a tattoo machine out of an electric motor and a spoon?

You trying to be Magyver or something?  The best tatoos are done w/ hygenic practices.  What you are suggesting is not hygenic at all.  You could really end up messing yourself or someone else up bad.  Leave the tatooing to the professionals please.  Its really the safest bet.

use a potato and two different metals as electrodes. The link will help you, do your own homework, or web searching atleast! it was the second link in google for g** sake!

Designing one is relatively cheap. Building a prototype is not so cheap. You would need to use precision linear stepper motors or other actuators and their power supplies and  cooling systems and so forth.\n\nI suppose that if you already have a lathe or milling machine you could possibly modify it by replacing the manual positioning and stock feed or tool advance controls with the above computer-controlled steppers, etc. I don't think it would do as good a job as a commercial unit. You would have to have a separate controller for each axis or each degree of freedom that the machine can work in. \n\nHave you tried looking for a used cnc machine that someone might be replacing with a newer unit? It is rare that they would just junk them; you might be able to find a used one or a model that is no longer in production. Try contacting manufactureres. Those are my best ideas, Hope they help.

well, i cant really explain it, but you can use rubber band or a mousetrap to power the car. if u google "mousetrap car" or "rubber band powered car," you'll find diagrams and steps on how to make it.

I had to do this before, but I had to make mine out of candy. If you're allowed to do that, use candy. It's pretty easy. Just get some wire, twist them to the right shape, and use different kinds of candy on them. Once you have those up, then you'll need the wires that go across to connect them. I find that candies like twizzles and gummy worms work well. It shouldn't take that long to make. Good luck!

MAGNET THATS POWERED BY ELECTRICITY

Yes. You'll need a lemon, a galvanometer or Vmeter, 2 stiff copper wires, a large paper clip, and scissors.\nStrip the insulation off on the ends of the wires. Untwist the paper clip and twist the end of one of wires around it. Squeeze and roll the lemon to loosen the pulp inside. Make two small cuts in the skin of the lemon an inch or so apart. Insert the bare wire and the paper clip through these cuts into the juicy part. The two wires should be close but not touching. Connect the free ends of the two wires to the terminals of the meter.\n\nNow watch the meter move!\n\nExplanation: Electrochemistry causes the two different metals (the copper wire and the iron clip) in the acid (lemon juice) to draw electrons away from one wire towards the other. They flow out of the lemon through one wire, go through the meter and then enter the lemon by the other wire.\n\nYou can even try to make your own galvanometer (an instrument designed to detect electrical currents) if one isn't available to you. You'll need a compass, 15 feet of bell wire (hardware store), and a small rectangular cardboard tray. Place the compass in the cardboard tray. Scrape off 1/2" of insulation from each end of the bell wire. Starting 6" from one end, wind the wire tightly around the box, circling it at least two dozen times. Leave another 6" of wire free on the other end of the tray. Rest your homemade galvanometer on the table horizontally and turn it until the compass needle is parallel to the coil of wire. Use these bell wire ends to attach to your lemon and paper clip.\nIt's fun!

If you mean electroscope then go here to see instructions on building your own:\nhttp://www.exploratorium.edu/snacks/electroscope.html\n\nHere's some more information:\nhttp://en.wikipedia.org/wiki/Electrometer

I believe the answer is conductive.  This is the process in which things are silver plated.  \n\nHere's how it goes.You fill a tray that has been lined with aluminum foil with salt water ( or is it plain water ? ).  You run a current through the aluminum foil.  The electrons in the the foil get excited due to the electrical current and start releasing aluminum ions ( Al-, I think )  Now, take your rusty, dull ' silver ' spoon.  Place it in the bath for about 2 hours.  Be careful,  electricity, water and living things don't mix well.  After 2 hours, remove the electrical current source and remove the spoon.  The free ions in the water would have coated the spoon, making it shining again.\n\nActually, toothpaste to clean the spoon is easier.

Get wooden matchsticks and cut the heads off of them.  Then it is a simple means of making the design and building it.\n\nOr you can order this kit.

Materials needed:\n     1 lemon\n     1 paper clip\n     1 copper wire (18 guage works well)\n\nProcedure:\n     1.   Straighten out the wire of the paper clip.\n\n     2.   Cut a piece of copper wire roughly the same length\n          as the paper clip.  Remove the insulation.\n\n     3.   Push the paper clip and the copper wire into the \n  lemon.  Keep the wires as close together as you\n          can, but don't let them touch.\n\n     4.   The fruit battery is now ready for use.  If you\n          have a voltmeter you can test how many volts\n          the battery produces.  You can also taste the\n          two wires and feel a tingle in your tongue.\n          (Note: you should only do this for very low\n          voltages such as those given off by lemons.)\n\nHow it works:\nAcids, such as the citric acid in lemons, tend to produce chemical substances called ions. These ions either have too many electrons (negative) or not enough (positive) Metals tend to attact these ions. \n\nOne type of metal will attract the negative ions and the other will attract the positive ions. This causes the two metals to have different electrical charges and electricity will flow from one to the other whenever you attach the battery to something like a radio (or your tongue). \n\nIncidently, the flow of electricity will eventually neutralize the ions. When this happens the battery is dead. \nand also see:

Well it is pretty easy to build a simple motor. There are instructions at this website.

Your best bet would be to purchase a robot kit somewhere. It would be far too difficult to make one yourself unless you had a thorough understanding of programming chips.\n\nAlthough if you want a very simple robot, try this: Find a switch, some wires, a battery, and a DC motor. Attatch the wires to the motor, and then to the switch. Place the battery in the circuit and then press the switch, and the motor will turn on. This is the basic principle of a robot, you can add multiple motors, timed switches, and eventually programmed chips to add more versatility and usefullness to the robot.

if u know how to build a cricuit i can explain you .!!!!\n\nbut if u dont know how to make a circuit... u r in wrong way ... u probably need to learn circuit making... or better yu buy a remote from a shop ;-)

You could find a picture of it and take to the tatoo place or another store and they should be able to do it for you
