Building a Smart 4-Channel PWM Controller with ESP32 and High-Efficiency MOSFETs
This 4-channel PWM controller uses an ESP32 (for smart control), TC4427 MOSFET drivers, and CSD17573Q5B MOSFETs (for efficient switching). It delivers precise, adjustable power (up to 18V/10A per channel) with minimal heat loss. Features include WiFi/MQTT control, local button inputs, and gamma-corrected LED dimming. Designed for a 12V LED spotlight, it’s also ideal for motors, heaters, or lab supplies. Fully open-source—schematics, firmware, and 3D-printable enclosure files are available.
How I Made a Clock out of Parts of Old Projects
One side effect of ordering PCBs from a professional fab house is that you always get more PCBs than you actually need. For example, when you place an order for a PCB prototype at PCBWay, you get at least 10 copies of the PCB, sometimes even more. In most cases, …
ESP32-S3-Mini-1 Development Board
Below I present my own ESP32-S3 development board. The reason for creating my own development board is twofold: Features and advantages This board is using the ESP32-S3-MINI-1 module from Espressif. The board’s features include the following: Schematics Here is the schematics of the development board: Board As usual, I designed …
Smart Timer Upgrade
For years this basic timer has worked very well in our house controlling the central heating. It was a success among all people because it was easy to set up and after the initial configuration we haven’t really touched it for years. It just kept working without getting in our …
An ESP-Now – WiFi Gateway or Preparing for Integrating Solar Powered ESP Based Devices to my Home Automation System
Since I live in an area where sunshine is almost always abundant, it makes sense to harvest energy from the sun as much as possible. This includes making various sensors around the house, especially the ones that are outside, operate with solar energy. This is usually not a very difficult …
A Word Clock with Extras
I have long been looking for a way to make a word clock (although there is no shortage of clocks in our home…), but until recently I haven’t found a financially reasonable way to make one. What changed is that I recently acquired a desktop 3D printer. This dramatically expanded …
Yet Another RGB Clock
This article is a new iteration on the wall clock I made a while back. (What can I say? I like LEDs, clocks and clock made up of LEDs…) This time I used a new PCB for driving the circuit and I designed a fully 3D printable enclosure for it …
Home Made TPM2.0 Module
Introduction With the recent launch of Windows 11 Microsoft also made having a hardware TPM module mandatory. Although this technology is not new (it was introduced in Windows 10 and Windows Server 2016), now, that most people can’t upgrade to Windows 11, it will (slowly) become mainstream. (My personal opinion …
