Introduction: DIY Telegraph

Picture of DIY Telegraph

Morse code is one of the most known codes in the world. Here's how to make an inexpensive telegraph to send messages in code. I did this for a science project. I got a low mark cause it dosen't qualify as a "simple machine". I hope it goes to better use out here.

Step 1: Connection

I. Connect the negative wire of the battery to the negative wire of the buzzer

Step 2: Buzzer

II. Attach an alligator clip to the positive wire of the buzzer and the battery to the clothes pin

Step 3: Two Way Calling

If you want to chat to someone with a telegraph, make another one and connect the buzzers with a long wire. Then when you type a message your buzzer and the buzzer at the other telegraph will make the same message.

Heya Matey, listen, this is just the instructable i'm looking for, you couldnt contact me about what you acctually used parts wise could, and how you hooked things together... I'll be building something like this with my scout troop so i need to know how it all fits together,,,,

like for example... withthe clothes peg where are the connectors fitted? Are you using a 12v battery? etc

I'm having a really hard time understanding how this all goes together...

So that explains why Almost every instructable ive senn you commented on

you saw this instructable? when i look for it on the search, i get no hits

That's because I'm an admin and your project was caught as spam for a lack of images (not that it is spam, it just got filtered that way).
