TL;DR
Agatha Mallett built a 4-bit counter using relay logic, making use of some small relays she had on hand, despite their poorly documented specifications. The project focuses on implementing D-type flip-flops with relays, which involves carefully managing the coil voltage to toggle the relay states. The counter features buttons for incrementing and clearing the count, as well as for setting or clearing individual bits, making it highly interactive.
Why This Was Curated
The article presents a practical project that demonstrates how to use relays to create a 4-bit counter, which is highly relevant for software developers venturing into hardware. It is accessible and actionable, providing insights into relay logic and encouraging hands-on experimentation, though it may require some foundational knowledge of electronics.
