Dalek

2006-07-24 by tteexxtt

Hello everyone,

I have just stumbled across this site whilst searching on google for a
ring modulator for my dalek that I am building!
I am looking for a ring modulator circuit that will produce a
triangular wave form at a frequency of 0 to 80Hz adjustable.
Can anybody help me out with this. I know that there are things like
the moogerfooger but I always think its best to try and build it
yourself. I have good soldering skills but very limited circuit design.
Thanks

hi
there are plenty of ring modulator schematics on the web.
i suspect you would have to try a couple to find the one that suits
your purposes best. most are fairly simple to put together.
possiby one with the mc1496, or Ken's passive ring mod would be good
places to start.
you will also need a source for the 0-80hz signal, search for a simple
LFO circuit using just a single dual op-amp ic, it should do the job.
you should be able to get a square and tri wave out of it and select
the best one.
cheers

A diode based modulator is a good place to start for making Dalek voices, as
that is what they used originally. (I have no idea what they use now.)

Have a look at the CGS58 Utility LFO. The core of that would be capable of
generating the triangle wave, though might need tweaking for the correct
frequency. Something like the preamp in the stomp box adapter could be used
to as a microphone preamp.

A power amp will be needed on the output.

Nicholas Briggs uses an elderly mic of some kind, a mic pre which can be overdriven, and a Moogerfooger ring modulator pedal for the dalek and cybermen voices in the new series and the Big Finish audio stories he writes and/or acts in.

here are some photos:

i'm also nearly nearly certain it's a square or pulse wave used for the modulation.



specifically to thread parent:
so what kind of dalek are you building? tv dalek, new dalek, movie dalek?
you can email me offlist. i would assume dalek building is OT on Ken's synth list.

Quoted from my friends email:
"....(from Brian Hodgeson, who actually did the Tardis, so he should
know), it was a Post Office ring modulator they used, along with
a BBC PEU/1 passive EQ (a big grey box with switchable low
pass and high pass filters). The original ring mod was lost when
it was borrowed by BBC Television to do some extra bits of Dalek
voices, and they mislaid it permanently. The VCS3 proved able to
do an adequate job instead. Note that a triangle wave was used
as the other input to the ring mod, not a square wave."
