What is this all about?

Where can I find out more about using simulators?

Can I buy this stuff from you?

  • No, but you can take whatever you find useful from this site (within the terms of the Creative Commons and General Public Licences), and build your own.

I’m not confident of building this stuff myself, where can I buy something ready made?

  • There aren’t many suppliers of off the shelf simulator equipment, but you could try David Bagley or Belfree.

Can I suggest an improvement/report a bug or documentation error?

Can you supply the PCBs?

  • No. Good quality PCBs are available relatively cheaply from OSH Park. All the current versions are uploaded and shared there, follow the links on this site or in the documentation. Alternatively you can get your own PCBs manufactured from the Eagle or Gerber files on GitHub. (Note: Surplus development PCBs may sometimes be available, please ask.)

Does it work? How many of these have been built?

  • At the time of writing, four complete simulators based on these designs have been successfully built and installed: Liverpool Cathedral (12 sensors, currently 10 standard infra-red, 1 magneto-resistive and 1 experimental 38kHz); Liverpool Cathedral (Saxilby Simulator) (6 magneto-resistive sensors); St George, Douglas (One bell interface, standard infra-red); St Mary, Chirk (6 sensors, standard infra-red); plus reference versions used for development and testing. Two simulators are in course of construction at St John the Evangelist, Higham (6) and St Margaret, Crick (8). In addition a set of magneto-resistive sensors has been constructed locally for Immanuel Chapel, Virginia Theological Seminary, Alexandria, for use with a Bagley interface.
