I'm a teacher, and wanting to make this, but where do I get a buzzer? I went to the local hardware store, and they were so very unhelpful.

Take a look at allectronics.com. They have buzzers, beepers, and transducers starting at $.75. A 9 volt buzzer goes for $1.25. Take a look at my Instructable about a communications activity/game - it shows you something you can do with a pair of Morse Code buzzers, etc.

This is cool. However, I traditional telegraphs use what is called a "sounder" instead of a buzzer (even simpler than a buzzer, too). The sounder only makes a noise when the key is pressed and released (it's silent if you hold the down). The Morse code is transmitted as the quiet spaces between the clicks. Here's a link to give you the idea: http://www.youtube.com/watch?v=l9beMc-gDSw&feature=related

I think I'm gonna build one right now..... Oh man!! no more wire :| No buzzer :( Better get back to my little inventory and get more wire from my hardware store, and I wish we had radio shack (but we don't in the whole country) :((

Nice telegraph by the way! Gonna get on with modifying it with proper switches and other stuff. Again nice telegraph :D

Jonny Rock Stah.
Your video on homemade electronic telegraph, was great.
I only wish that I could copy and print it out on paper. TNX. Tip.

whats a mini buzzer?

redgator12 in reply to nickjonasloverApr 20, 2009. 4:20 PM

A mini buzzer is a small device that when charged with an electrical pulse buzzes until the transfer of energy stops. You can buy one at radio shack for $2.

My 11 year old daughter was intrigued by the ham radio guys at the AZ Science center who were teaching code. She made her name in morse code and wanted to do more. I wanted to avoid a complicated build but still have some fun. I think we will make this over spring break! Thanks for the easy and cheap idea!
