So here we are talking about a very simple, completely transistor-based solar switching buck converter circuit. What it does is, it takes an input from 40V to 60V and converts […]
Dry Run Protector Circuits using Transistors only
The basic dry run protection circuits using BJTs shown here provide simple ways to check for low water levels in an underground tank but without needing to use probes inside […]
Simplest Mosquito Repellent Circuit using Transistors
Let’s face it, mosquitoes are some of the most annoying bugs out there. They not only bug us like crazy but they also have the potential to spread some really […]
Simple Strobe Light Circuits using Transistors
You might think strobe lights can only be created using complex xenon tubes, but that’s not true if you find them interesting. Having the right driving circuit that can handle […]
Water Level Controller Circuit using only Transistors
I have got this gadget called an automatic water level controller circuit. It’s pretty neat, it checks if the water in my tank is too low or too high and […]
High Low Temperature Alarm Circuit using Transistors
This high/low temperature indicator circuit uses only BJTs and the temperature is being monitored by a thermistor. This straightforward temperature alarm circuit is set to sound an alert (either vocally […]
