So, if you’re looking for the the simplest and cheapest shortwave transmitter circuit, it’s here. This transmitter is very low power and very stable as well, uses a readily available […]
How to accurately measure low resistance with cheap Multimeter
We often need some low value resistors, less than 1 Ohm. Mostly as current sensing resistors in power electronics projects. You can’t measure less then 1 Ohm with cheap multimeters. […]
LM317 constant current source circuit design
A constant current source source can supply a fixed current to a load regardless of input voltage or load change. LM317 constant current source is one of the simplest design. […]
What is dielectric resonator oscillator and it’s application
A dielectric resonator oscillator is basically a high frequency oscillator, operates within a range of few tens of gigahertz. The main frequency determining component is piece of dielectric material, usually […]
