Build Inductor at home?

If you want to build it to a specific value, I recomend getting a copy of The Radio Amateurs Handbook from your local library.  It has info and formula for air core, ferrite core, and toroid core inductors.  You might try their website www.arrl.com

You can use an integrated circuit, like LTC6906 from Linear Technology which goes up to 1MHz at 2.25 - 5VDC supply,\nsee:  http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1010,C1096,P9790,D6998\nAlternative: MAX5094A by Maxim,  see:  http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5017\nI didn't have the time to check the output power, but if it's not enough, a simple emitter stage transistor will do.

You can buy kits, I think Maplin do them. Or other electonic hobby shops.\nNot expensive really unless you get into heated etching tanks etc\n\nbassically you buy copper covered boards you then transfer your design to the boards with an etch resistant pen or for a better job using decals.\nThe board is then dipped in an etching solution which removes all the copper not protected.\nThen drill the holes for you components and job done.\nYou can also get 2 sided boards.\nBut multi layer boards isnt a DIY job

You can use oil to do it.  Some people have started making computers at home that are submerged in oils of all sorts, since it doesn't conduct electricity.

Yes, there are kits you may purchase to do this at home.

Not easily. IC fabrication techniques are essentially planar and can't be used to create helical structures in an IC. \n\nWhat can be done is to simulate inductors using capacitors (small value capacitors can be fabricted on ICs), and active circuitry. Sometimes this is possible, but sometimes it's not enough. Particularly at low frequencies (eg, audio signals from near DC to perhaps 20KHz), external inductors may be the only choice.

Just buy the plugpack.\n\nIf you want more amps, or variable volts, be specific.

It is assumed you have completed all of the tutorials on basic electronics because without that basic grounding you will go nowhere here. It is assumed you have a good understanding of ohms law to be able to follow the necessary calculations here.\n\nMany people are interested in Audio Amplifier design. If this is your area of interest then the first thing I sincerely recommend you do is buy this excellent reference book through my amazon affliate program.\n\nHigh-Power Audio Amplifier Construction Manual - G. Randy Slone, Randy Slone - highly recommended. Paperback and 476 pages.\n\n"Design and build awesome audio amps. Amateur and professional audiophiles alike can now design and construct superior quality amplifiers at a fraction of comparable retail prices with step-by-step instruction from the High-Power Audio Amplifier Construction Manual. Randy Slone, professional audio writer and electronics supply marketer, delivers the nuts-and-bolts know-how you need to optimize performance for any audio system--from home entertainment to musical instrument to sound stage".\n\n"Build a few simple projects or delve into the physics of audio amplifier operation and design. This easy to understand guide walks you through: Building the optimum audio power supply; Audio amplifier power supplies and construction: Amplifier and loudspeaker protection methods; Stability, distortion, and performance; Audio amplifier cookbook designs; Construction techniques; Diagnostic equipment and testing procedures; Output stage configurations, classes, and device types; Crossover distortion physics; Mirror-image input stage topologies".

If you go to PCB Express on-line, you can download some simple graphical type programs to design a schematic and do a board layout for a prototype board.  You enter credit card information and in a few days, you will have three prototype boards mailed to you.  You then populate them and solder it up.  This is only one of several services to do this.  It works pretty well, assuming that you are willing to do the work yourself.  \n\nIf not, I would make a flowchart on paper of what you want the circuit to do and submit it to an electronics or robotics on-line site or message board for help, go talk to a teacher or professor, etc.

Basically, you just need two different types of metals to generate a current. I assume your using copper as your other metal type.\n\nIf you dont have any zinc wire, you could try using a galvanized (zinc coated) screw.\nOr if you want to use another metal all together, try Aluminum in the form of Aluminum foil.  An Iron nail or a chunk of lead would also work, but not as well.
