Dalek voice ring mod anyone?

MannyE · 13th October 2011, 08:11 PM

I am trying to put together a ring mod that would duplicate the Dalek voice. (If you don't know what a Dalek is you can't really help me can you?

)

The BBC guys probably used a Moog Mf-102, but I want to build something compact and it doesn't really have to do much else than the Dalek voice...

something that would fit inside a life-sized dalek... to give a hint or two.

I haven't built one in a very long while. You need two center tapped audio transformers around 600 ohms is fine. Then a diode bridge, four 1n4148s should work. An oscillator for the offset frequency, an 8038 Intersil chip should work.

If you want to get fancy use three transformers, two diode bridges and two oscillators. The first one should step you up by 30 K in frequency and the second drop you by 30.2 or so. That way you can avoid filters.

The whole thing can run off of 2 9 volt batteries.

Ken Stone's Modular Synthesizer

thats a traditional one, like they would have used for daleks, but you can do it without transformers or diodes (more accurate but doesnt sound the same)

you might want to adapt the op amp parts of the circuit to use a single supply instead of bipolar, so you could use batteries,

Very cool 'cause I just bought a toy voice changer for Halloween and it's pretty awful.
May have to try this.

You can make a ring mod with an OTA (generally cheaper than the traditional transformer method).

I think the toy voice changers just use an analog switch to rapidly switch the audio on and off. A bit like standing behind a big fan and shouting through the spinning blades.

I think the actual sound of a Dalek voice is created by a ring mod with a 100Hz triangle wave as the carrier?
