So this 35238-MP Multi-Function Timer module is an digital adjustable programmable timer which we can use it for doing time-based automation things. Inside it, there is a microprocessor that watches time very closely and makes the relay turn ON or OFF after a set time. So this thing is good when we want to turn […]

Designing a Power Factor Correction (PFC) Circuit Using UC3854 – Key Considerations
The IC UC3854, what it does is, it helps in active power factor correction, right? Now normally, if we don’t correct the power factor, then power system will pull current from the AC mains in a way that’s not a nice sine wave but rather distorted. This IC takes care of all the control stuff […]
Automatic Curtain Open-Close Circuit
We are happy to share an automatic curtain control circuit kindly provided by Mr. August Peterson. This design helps to open and close curtains by sensing light from the surroundings. It uses an LM393 comparator, a solar panel as a light sensor and a 24V motor. The circuit makes the curtain open in the morning […]
XL3608 5V, 9V,12V DC, 2 Amp Boost Converter module
This XL3608 2A mini DC to DC Boost Converter module is super compact and efficient and it is just perfect for powering all sorts of devices and systems. Let’s learn about its main features in greater details: Main Features: Input Voltage Range: We can feed this module with an input voltage ranging from DC 2.5-11.5V. […]
How to Connect Digital Ammeter, Voltmeter Modules M4430, M3430
In this post I will be talking about the Chinese M4430 digital ammeter, voltmeter module which is a really neat, compact digital meter that you can mount on a panel. Whats great about it is that it is designed to measure and show us both the DC voltage and the current at the same time. […]
TPS24710/11/12/13 Hot-Swap Controller Circuit Explained
When we talk about hot-swap controllers, it is basically an electronic device or integrated circuit (IC) that allows you to the insert or/and remove circuit boards, modules or parts within an active system without having you to switch off the system. It regulates the surge current whenever a component is installed and protects from short […]
