- Interfacing switches and relays to the real world in real time - Designing the external interface to an industrial or automotive application can be challenging for an uninitiated systems engineer. The bouncing of switch and relay contacts can produce arcs that threaten system reliability. ESD can also threaten reliability and uptime. Fortunately, there are ways to ease the task of designing an interface between the inputs of a microcontroller and a hostile industrial or automotive environment.

- High Quality Intercom - A very high quality intercom, which may also be used for room monitoring. This circuit consists of two identical intercom units. Each unit contains a power supply, microphone preamplifier, audio amplifier and a Push To Talk (PTT) relay circuit. Only 2 wires are required to connect the units together. Due to the low output impedance of the mic preamp, screened cable is not necessary and ordinary 2 core speaker cable, or bell wire may be used.
