howdy all. simple project here. I'm not an expert, but I think I can do this. I have several old rotary phones in my home. I'm having problems finding a project for a small DTMF generator that I can hold up to the mouthpiece when using a rotary phone to call in to a menu-based message system. Something pref using like 9V. batt supply. Seems they should be all over the net, but most seem based on use with a PC or for RF. Just point me in the right direction. Thanks in advance.
