I came across an inverter design that is built with CD4047, which is a versatile CMOS IC commonly used as an astable multivibrator or flip-flop to generate stable square wave signals for driving MOSFETs in push-pull inverter configurations. It is similar to the 555 Timer in that it can be…

The 555 timer IC is a versatile electronics device because it can be used in different electronics circuits, from power supply, to motor control signals, to timing signal, pulses with different pulse witdth, that is PWM(pulse width modulation) signa…
I came across a frequency doubler circuit built with 555 timer IC. I checked this circuit with proteus simulation, but I did not get exactly double of the input signal frequency. I got this circuit diagram from the book Electronics projects volume …
Boost converter are voltage converter with higher output voltage than the actual input voltage . I wrote about how to build a buck converter with 555 timer IC9l0l0l. Here I wanted to take a note on how to build a boost converter using 555 timer to c…
Lately, I have been learning how to design 3.7V to 5V boost converter for powering esp32-cam. Then I thought how one can get exactly 5V or other desired output voltage from a boost converter. I know there is equation relating the input, output volt…
I have been looking into power supply circuits for powering ESP32 and ESP32-CAM, different techniques, circuit diagrams etc. I was interested in 5V output to power esp32-cam, because I have heard that it is better to power esp32-cam with 5V rather …
The ESP32-CAM is a powerful microcontroller with built-in Wi-Fi, Bluetooth, and a camera interface, but it can be power-hungry—especially when using Wi-Fi and the onboard camera. If you're looking to make your ESP32-CAM project portable , one of…
🔧 What is the MT3608? The MT3608 is a high-efficiency, step‑up (boost) DC‑DC converter IC, commonly used on small modules for electronics projects. It takes a lower input voltage (like 2–24 V) and boosts it to a higher adjustable output (up to ~…
I had disassembled the Arduino Blutooth controlled RC car that I had built many months ago for adding crane part to the car. I did not successfully completed it but I was/am close to it. I wanted to build the crane part on top of the arduino blueto…
