Chris writes in with some DIY Radio transmitter circuits…

If you can receive, what would you like to send? Here are some of the radio broadcast circuits that I like lately. Some of them I have built, others I would like to or am in the process of testing. One idea would be to set up an information kiosk, run the transmitter and player on electricity derived from renewable energy like wind or solar. You wouldn’t need a huge generator to make it work, none of them seem to draw much current. It could run forever in the right setup.
