AM Transmitter

 AM Transmitter

You are going to build an AM radio transmitter AND you will be shown how it works. When you finish your radio, it will look something like mine in the picture below.

 

step 1:

Parts and Prep (Small Stuff)

These are the small components you will need==
--Small Stuff--
- 555 timer chip
- NPN transistor
- two #103 capacitors (0.01 microfarads or 10,000 picofarads)
- #102 capacitor (0.001 microfarads or 1,000 picofarads)
- some short wires
- two 1 Kilohm resistors
- 10 Kilohm resistor
- 1/8 inch (3.5 millimeter) female audio jack (yours may have more or less than three
wires, but it must have at least two)
- 5 Kilohm potentiometer

Image Notes
1. 555 timer chip
2. NPN transistor
3. two #103 capacitors
4. #102 capacitor
5. two 1 Kilohm resistors
6. 1/8 inch (3.5 millimeter) female audio jack
7. 5 kilohm potentiometer

8. 10 kilohm resistor
9. just wires.

step 2: Parts and Prep (Bigger Stuff)

==These are the bigger components you will need==
--Bigger Stuff--
- 1/8 inch (3.5 millimeter) male audio cable
- AM radio receiver
- Antenna. Yours doesn't have to be made out of a pop can, but the pop can works
- Breadboard
