what is the basic and necessary parts to built a radio manually . i want to built a radio of my own . so what can i do for that..
Purandhar.R A crystal radio receiver, also called a crystal set, is a very simple radio receiver, popular in the early days of radio. It needs no battery or power source and runs on the power received from radio waves by a long outdoor wire antenna.

homebrew 3-tube ham radio receiver ARRL Simple-X
How do you connect a DC motor to a radio control receiver?
my friends and i recently got into robot building and have everything figured out apart from this.
I know that the receiver is designed to power servos, but how can i get it to drive the DC brush motors that we got from radioshack? we are on a budget and didnt want to have to spend money on servos, and any help is appreciated ![]()
If switching the motor on and off is enough you could try a relay in the receiver output instead of a servo. If you need a degree of variation of voltage to the motor then you'd need to use a small power amplifier or motor controller.

Ditto to Martin Skov's comment.
Is a radio illogical? To some pre-industrial human it surely would be! The interaction between brain and mind is more complex than a radio, since the brain focuses, modifies, filters, blocks, and distorts mind, and is not a simple radio receiver.
It is amusing that we both laugh at each other's illogic. Your illogic: all your materialist thoughts are mediated by consciousness, and, alas, we have absolutely no idea what consciousness is (and subsequently, what thought is). Neither thought nor consciousness have ever been detected or measured, or shown to even exist, tho we all believe they absolutely exist. You can't prove I exist; you can't even prove you exist! These “existences” are mere interpretations. Are you dreaming this? Prove to me you're not.
smile. It's a messy business, eh?

The company that took Radio out of it's name is selling a radio app that costs $80. Not sure the performance of HD so far indicates a desire among iPod users for a radio receiver, especially one that could be described as the “HDTV converter of radios”. Not exactly a simply plug-n-play device, this one. There's that big, fat iPod-required cable in addition to the HD receiver, flopping around.
