Amplitude Modulation with Simple AM Radio Transmitter @RimstarOrg

Uploaded May 2013 | Updated September 2026, 3 weeks ago

How amplitude modulation works using a simple AM radio transmitter as the example. This shows how the audio wave is turned into a radio wave for transmitting from a transmission antenna to the receiving antenna of a crystal radio or other radio.

For how to make the simple AM transmitter watch "How to Make AM Radio Transmitter":

$Pyramid Hologram - How to Make/How it Works with Princess Leia Hologram Easy to make hologram showing Princess Leias message from Star Wars IV, a flying pterodactyl and a skull. All you need to make is a 4-sided clear plastic pyramid and a drawing with 4 different views of an image. Some of mine are even animated.

A hologram refers to a thing created using a specific process and involves the use of laser, interference, diffraction, light intensity recording and suitable illumination of the recording [from wikipedia]. This pyramid hologram is really 4 views using a trick called Peppers Ghost, the result being something that is popularly known as a hologram.
