KA431/TL431 Time Delay Switch
The real inspiration for this post actually came from lots of lame designs seen on the web. The last drop was a reasonably great written article presenting a number of blueprints to build timer circuits […]
Analog Constant Current Generator
I’ve recently completed the basic design of a general-purpose analog constant current generator employing easily available electronics components. This is a simple circuit that is easy and cheap to build and is very useful especially […]
Poor man’s Over-Current Detector
Presented here is the basic circuit of an over-current detector built around a handful of easily available and inexpensive electronics components. This simple circuit for DC devices wakes up when the connected output load draws […]
