Notes and Musings on the DAVIAC Relay Computer

Welcome to DAVIAC. The purpose of the DAVIAC1 Relay Computer it simply to re-demonstrate the most basic principles of computing in a highly visual way in which every bit can be tracked continuously. To this end I have chosen large format relays with easily visible contacts inside clear transparent cases. The single pole SPDT (single pole double throw) examples have 12V coils and 240V, 10A contacts. These relatively large power relays provide not only the visual evidence of operation, but also a most satisfactory sound. I had a very clear idea of the sound I wanted, and am very happy with the result.
