The best and most productive way to gather the parts for this project is to take apart and salvage old and or broken electronics appliances. This may take some technical skill.

The safest bet is to purchase a fresh set of parts and tools (if you don't have them) Here are a couple online web-stores which sell the parts and tools needed for this project:

http://www.amazon.com/ - amazon has all the parts and tools needed for this project. However, amazon tends to sell electronics parts in large bulks which means you are likely to pay for parts needed to build around 100 of these transmitters.

http://www.conrad.com/ce/ - One of the greatest electronics web- stores in western Europe. You can cheaply buy individual parts needed for this project.

http://www.lemona.lv/index.php?lan=en&toc= - One of the best electronics web-stores in eastern Europe. You can buy the parts needed for this project at very low prices.

https://www.radioshack.com/ - One of the most popular electronics web stores which ship worldwide and sell all of the components at low prices.
