About This File

The assembly manual for the latest version of the Project Dalek voice modulator, designed and written by @elembivos.

 

Note: This Mk5e assembly manual replaces the earlier Mk3 booklet.

 

This manual gives you all the details you need to put together a voice modulator which sounds great and is also cost effective. You will need to source your own components in order to use this manual. However, PCBs will be available from time to time, via the Forum. Check out the Support Topic for the latest information on what is currently available.  This booklet can also be used in conjunction with the files located here and here, which will allow you to order PCBs directly from a PCB manufacturer. If you have access to a 3D printer, you can print your own case/enclosure.

 

This manual is also available to buy as a full colour printed booklet. Click here for details.

They are available from the 'subscribe and purchase' section, but I see you've already found that and ordered one. :)

This looks like a nice design.  I like the fact that the current version uses a sign wave oscillator and what looks like a balanced modulator (built around an LM13700 transconductance amplifier), which ought to make a more authentic-sounding voice than a simple square wave "chopper" design (which one of the older designs used).  One idea for future development could be using a digitally-generated sign wave.  I have written and tested assembly language for a PIC microcontroller to generate sign wave outputs (using a pulse width modulation output) at a range of preset Dalek frequencies.  I would be happy to edit and share the code if anyone is interested.  There are small eight pin PICs available with PWM outputs that could produce a sign wave with very few external components - perhaps just some push buttons to choose the pre-set output frequency and maybe an op amp output buffer might be needed to drive the LM13700 modulation input.

I was wondering, what microphone is being shown in the manual? I would like to know so I can use that one
