Mad Circuits

Are you looking for a somewhat difficult FM transmitter to build. This one might be right up your alley. This is a 500 MW FM transmitter. While 500 MW doesn't sound like a lot of power, that is a good deal more than most of the FM transmitters listed on this site. I've listed the details at the end of this article. Before building, check your building checklist, do you have:

If you are looking for good electronics programs and instruction located in India, here is a list of resources to get you started at the end of this article. First, though a couple of key questions.

• Be prepared to answer why you would like to attend electronics school. What is your objective for learning electronics.
• Have you done any work with electronics before in India. Do you know what a potential job would be like in India working in electronics?

VHF spy circuits or Very High Frequencies circuits can transmit for a long distance. For that reason, you should check what laws you have in your country on fm transmitters. Here is the circuit, let's see how it is built:

Using a breadboard to prototype electronic circuits can save you a lot of time. Breadboards are small plastic boards with strips of metal in the bottom of them which allow you to build circuits on top of them.

I purchased several breadboard kits from radio shack. I purchased a small one and then decided to get a larger one that had a power post on it. When you purchase a breadboard, also purchase the breadboard jumper kit which includes numerous small peices of jumper wires so that you can build circuits.

Using a soldering iron the correct way can save you a lot of time and aggrevation. In this article, I'll explain how to use a soldering iron correctly and save your sanity.

Are you looking for the big daddy of oscilloscopes. The DLM2000 oscilloscope has all the bells and whistles you could get out of an oscilloscope. Well, it should for a $4,500 oscilloscope. There are 2 channel analog models available and 4 channel digital models available. For more details, please visit the manufacturer's home page - http://www.tmi.yokogawa.com .

This VHF FM transmitter circuit uses a Hartley type oscillator and is best build with an ECM type microphone insert:

This is a low power 2 transistor fm transmitter. It is not the best quality transmitter but doesn't take too long to build and doesn't have too many parts. If you would like a better fm transmitter, then look for one of the more complext ones listed here.

This fm transmitter takes about 20 parts and is powered by a 9 volt battery. It can be affected by the electricity in a person's body, so that being said, this does not make for a good personnel microphone or bugging device.
