In this post we are going to look at a very special and robust design: a purely discrete 4 transistor automatic street light circuit. Many hobbyists ask me why we should use four transistors instead of a simple IC 555 or an op amp. The main reason is that some makers love old school, pure […]

Precision Current Sensing and Monitoring Circuit using IC NCS21xR
If you are looking for current shunt monitors or current sense amplifiers then you have landed at the right page. Current shunt monitor is an instrumentation amplifier which senses the current across a shunt resistor in a system, and converts it into a logical signal output for triggering a switching device such a relay, transistor […]
