Understanding Triac Snubber Network Calculations
You may find electronic circuits that frequently utilize triacs to manage mains powered loads. However, these setups commonly feature an inconspicuous capacitor and resistor combination across the triac – a snubber network. The functions of these components are more intricate than they seem. Exploring snubbers and grasping basic triac theory is valuable. Triac Operation A […]
GSR Sensor Circuit for Biofeedback Measurements
In this post I have explained how to build a very simple GSR sensor circuit using just a couple of transistors and a few other passive components. A GSR (Galvanic Skin Resistance) sensor, also known as a skin conductance or electrodermal activity sensor, measures the electrical conductance of the skin, which changes in response to […]
High Voltage Constant Current Source Circuit
The presented circuit offers an adjustable constant current source capable of reaching up to 60mA, operating at voltages as high as 350V. Circuit Description The input stage, consisting of resistor R1 and zener diode ZD1, delivers 8V to the regulator (a 7805), maintaining this voltage relative to its reference line. This voltage level ensures sufficient […]
