How can I build my own telegraph?

The concept is to build an electromagnet that cuts the circuit when energised. This produce a buzzing effect

Design your own!  Go to any electronics store and you can customize one with some software.  This is our opportunity to be creative.

you can go to www.piczo.com i think thats one of the sites that you can make your own fre site on, thats what my brother told me once

Do you mean services?\n\nPhone lines are easy - contact BT or alternatinve suppliers in your area like cable.\n\nIf you need water, gas, sewage or electricity that is a more involved process on which I am happy to advise if you wish.

make any sensing devices, which has the altest features. u can get a lot abt them on internet and modify them for the latest demands

oh this has been awhile....ok a block of wood, a couple nails, some tape, some wire, and a six? volt battery.\n\nyou are basicaly making one of the nails an electro magnet so that when the circuit is completed it comes on and pulls down one of the wires to the top of it making a clicking noise, open the circuit the wire will spring back up.  \n\nhere is a more complicated one that will send to another one\nhttp://www.apluschilddev.com/headstart/services/projects/easy_make_telegraph.htm

Give the site below a try! Good luck.\n\n<This is for fun only. If you are actually trying to do this to heat your house or use for power, I don't think you can do that. You would need commercially made cells, but you could set up the system yourself.>

do a project in radio transmission ..........parts for this project r fairly cheap and easy to do.........

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

Become a radio ham and use "roll your own" equipment. Frequencies from near DC to light, analogue and digital, radio and TV - it's all there. If you can get your kit to work, you have the added bonus of being able to talk shop with others who have done the same.\nIn most countries, you no longer have to learn Morse to qualify (but if you want to be economical with power and confirm that you too can get across the Atlantic with 1 watt erp, you'll need Morse).

hi,\n\ntransformers you can buy for pretty cheap at any decent electronics or  hobby stores (radio shack sucks these days, but they probably still have them).  \n\nhowever you can make them really easily.  all you need is a hunk of steel or iron (some kind of rod-shaped thing would work, as would a donut-shaped loop).  take one wire and wind it around the piece of steel N times.  take another wire and wind it around a different part of the steel M times.  congratulations, you have just built a transformer that will step up/down voltages by a factor of M/N (or N/M, if you hook it up the other way.)\n\ncheers-

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
