Most of the power electronics system use big heatsink to dissipate excessive heat. Some of these uses active cooling method, by using a fan on heatsink which help to remain the temperatures more stable. But when running these things on a low power fan is still on and feel noisy. So why not to make…
ESP8266 is very powerful and most preferred microcontroller in IoT. This is used worldwide not only because of the wi-fi compatibilities but also due to open-source network. This comes with 32bit microcontroller running at 80Mhz. But it can be overclocked to 160Mhz keeping cooling conditions in mind. ESP8266 is designed on a very small PCB…
I made many amplifiers and preamplifier project in past. But due to the continuous demand I have some new Ideas about amplifiers. But all of them are half without a proper preamplifier circuit. Because preamplifier not only boost the signal but also arrange low and high pass signal on different output channels. Looking into the…
In last tutorial, we made a preamplifier for 5.1 party boom box. Now it is the time for the amplifier. We will design the compatible 5.1 amplifier for this, as mentioned earlier to drive 100watt subwoofer and 4x 25watt speakers. TDA series integrated circuits are best for this purpose that provides a high-fidelity output stage….
I want to make a big party boom box, with a 100watt subwoofer and four speakers of 25 watts each. But we need a better amplifier and preamplifier board which can meet the requirements. I searched a lot but some of the amplifier systems are very expensive or some of them even do not support…
I made many audio amplifiers using Class AB configuration. But, working with those big amplifiers are very heavy job. These amplifiers need more power, dual supply and heavy rectifiers/filtering circuits. We cannot power these Class AB amplifiers using single SMPS, A linear power supply with center tapped transformer is must. Now the real problem comes…
Inverters are widely used devices in electronics and electrical circuits. An inverter converts corresponding DC voltage into AC. We are very familiar with linear dc power supplies, which is used to convert 220v Ac into low voltage high ampere DC. In the same way, A high ampere battery or supply is required to step up…
In this post, we will learn how to use Reyax RYS8830 GPS/GNSS Receiver Module to retrieve time and position data from satellite navigation systems. The RYS8830 module from Reyax is based on Sony CXD5605GF/CXD5605AGF technology & comes as a small SMD component. The RYS8830 GNSS modules can be used in tracking devices that need to…
I got my hands on REYAX Lora modules, and in this tutorial, we will configure these modules to communicate with each other. Lora platform is known for its long range as specified by the name LoRa (Long range radio). The normal communication distance is 8Km with rubber ducky antenna. Internet is not required in these…
Hello guys, I made want to make a 7-segment display. But this time with bigger digits and RGB effects. Because this can be used to display some readings like Clock with Nodemcu, temperature monitoring using Arduino. Also, with an option of color changing after each second or next reading. I also have the similar one,…
