Hen House Automatic Door Controller Circuit
In this article I have explained an automatic door mechanism circuit that responds to the ambient light conditions by keeping the door open during day time and closed during night. Here the application is used for operating a hen house door. The idea was requested by Mr. Gavin Sweet Technical Specifications I have a project […]
Solving Darlington Transistor Formulas and Calculations
Now in this post you will learn about this amazing BJT device which is called Darlington Transistor. It got this name after genius engineer Sidney Darlington who first gave this idea, so we remember him. What Is Inside Darlington Transistor Basically this device is like special combo of two normal NPN or PNP bipolar junction […]
Modified Sine Wave Inverter Circuits using IC 555 and 4017
When an inverter with square wave AC output is modified to generate a crude sinewave AC output, it is called a modified sine wave inverter. The following article presents interesting modified sine wave inverter designs with exhaustive descriptions regarding its construction procedure, circuit diagram, waveform output and detailed parts lists. The designs are intended for […]
How MOSFET Works like a Switch
Now in our earlier talks we saw that the N-channel Enhancement-mode MOSFET or e-MOSFET works nicely when we supply it with positive input voltage, so this is very important to remember. This type of MOSFET has very high input resistance, almost close to infinity, and because of that we can use it easily like a […]
How MOSFETs Work: Depletion Type, Enhancement Type
Two main types of FETs that presently exist are: JFETs and MOSFETs. MOSFETs can be further classified into depletion type and enhancement type. Both these types define the fundamental mode of operation of MOSFETs, while the term MOSFET itself is the abbreviation of metal-oxide-semiconductor-field-effect transistor. Due to the fact that the two types have different […]
