The Liverpool Ringing Simulator Project
The Type 1 simulator is no longer under active development. The repository for the Type 2 simulator is at https://github.com/Simulators/simulator-type2, and you should start there if you are building a new simulator.
Here you will find archived all the resources for building the Liverpool Ringing Simulator Project's original (Type 1) simulator interfaces and sensor heads, including:
- Hardware & Software Manuals
- Firmware Source Code
- Eagle PCB Designs
- PCB Fabrication Gerber Files
If you didn't get here from http://www.simulators.org.uk/, you might want to go and look at that, too.
