hi every one i'm interested in communication branch so I'm searching for new interesting projects in that branch do u have list of that? or can u guide me for useful sites thanks for all

here is some pictures, see them ang give me your comments please project.zip

if we want to use electromegnatic by shanking which produce ac current then by using bridge diode we convert it to dc current, then store this to capacitor, after that discharge the capacitor to lamp, is it will be working or not??? second which can we use to control the discharging of the capacitor?? aslo is the idea of radio wave applicable here. instead of electromegnatic

thank you very much for your point but i don't want to use radio wave i want to use i said before magnetic coil which produce ac current then by using bridge diodes (full wave rectifier) concert it to dc current, after that the dc is stored in a capacitor, then discharge it to some leds, of course i use the current control to control this discharging, by my problem is how can avoid discharging in the opposite way of the daiodes?? :)which element can i use resistor or what???

sorry, i didn't det your point, would you explain more, how can i use transistor radio receiver circuit instead of coil as power source?? 8)

thank you for youe attention, really i found some clear picture about this project in this link http://www.electro-tech-online.com/viewtopic.php?t=5998&postdays=0&postorder=asc&highlight=flashlight&start=30 i want u to read what was wrote there and give me the idea and the steps of design this project and this is the main idea of the project COIL -> Bridge Rectifier -> Capacitor -> Current control -> LED

thank you my dear what you answer is exactly what I want but unfort. i don't knew the circuit or how it is build? if u knew something tell me please :)

hi all, first of all i'm happy to become a member in this ammunity which is of course contains a lot of information about electronics, so i will be a good member and i will be helpful :) second, I'm searching about project called flashlight with no batteries, if any one has some information or websites about it please tell me. thanks :)
