Build your own intercom or walkie talkie out of two old cordless phones

Step 5 Clean up

If you use two cordless phones you have just made a makeshift home base walkie talkie. Clean up your area and drink your milk call a friend.

Note: to ring one of the phones you will need a ring generator, but that is another project for another time. Have fun.

I have no clue what you are doing. How do these phones talk to each other? What are you doing with that battery? Can you do this with two cell phones as these people suggest you can do? http://blog.dialaphone.co.uk/2007/12/13/14-things-to-do-with-an-old-cell-phone/

exactly what do the cords connect to? from what, to what?

will hooking a regular power cord up to it, and plugging it into a wall outlet create a ring?

It may ring, but probably blow a capacitor, or catch fire. There is more current than you need. Spark Fun has a great little article and schematic on how to build a ring generator. they use it in a slightly different way but it has all the right gut. At some point I'll adapt it for this project.

does it work without the ring generator?

If you read it it says the ring generator is for the ringer. This does not have any effect on using the phones for the intercom, just the ring feature.

How about two of the same phones with a transfer function. Then when you want to talk to other party. just hit transfer the other phone would ring then hang up then talk to each other. Would that work for ring generator?
