Bugs are soooo creepy!!! It's making my skin crawl just thinking about it!

Time capsules are always interesting.......wonder if you could incorporate something like that.

This question I can answer Old rotary type phones (and earlier), used a 90 volt 20 Hz AC ring pulse. Proper voltage, no problem. Frequency, different animal entirely (modern AC is 60 Hz here in the US). I'll just leave it at: It can be done. However, I don't consider it worth the effort to engineer a device to make it ring the traditional way. When it would be far easier (and likely quite a bit less expensive) to simulate it with a micro controller, mp3 player, and an amplified speaker.
