This is an extension of an article published here some time ago (Discrete Linear Voltage Regulator). At this point let us dive a little deeper into the design concepts of the far-famed linear voltage regulators. [ ] The post Quick & Easy Voltage Regulators appeared first on Codrey Electronics .
Welcome STEM kids to old school electronics! The midget tone generator is as simple as useful. With just a couple of transistors and a few other parts, it is fairly easy to build the belittled [ ] The post Midget Tone Generator appeared first on Codrey Electronics .
Today’s composite electronic designs are likely to have many different power supply rails. This is especially true in circuits employing analog electronics along with microcontrollers. As designs get more complex, the number of power supply [ ] The post Isolated Voltage Monitors appeared first on Codrey Electronics .
A cupboard light is a small and useful undercabinet light source that can be easily installed in cupboards, wardrobes, and kitchen cabinets. It can shed light into dark corners and the tiniest nooks and crannies [ ] The post Cupboard Light DIY appeared first on Codrey Electronics .
Today we will see how to build a flashing float using a handful of commonly available inexpensive electronics components. This is the circuit diagram of the flashing LED float… List of components is shown below. [ ] The post Flashing LED Float appeared first on Codrey Electronics .
Interior signage such as lighted exit signs, plays an important role in keeping clients and staff safe during an emergency. This post shares the design idea of a simple and economical LED exit sign. This [ ] The post LED Exit Sign appeared first on Codrey Electronics .
Here is a simple high water sensor system to prevent costly to correct undetected water damage such as that caused by leaking pipes or corroded water heaters. The high water sensor circuitry will detect any [ ] The post High Water Sensor appeared first on Codrey Electronics .
A zener diode is often used as a simple voltage reference device. This post looks at how to create a variable (or adjustable) zener diode.
