There are many guides on the internet on this topic but most of them are incorrect. You can not get audiophile-grade music on your flagship smartphones such as Samsung S22/S23 Ultra with advanced music apps such as PowerAmp, Samsung's official USB C to 3.5mm converter and consumer-grade earphone such as Boat BassHeads 122. The combination we have mentioned above, i.e : Samsung S22/S23 … [Read more...]

ESP32 Arduino Water Tank Level Monitoring Using Laser ToF Sensor
Guides for building a DIY water level monitoring system using Ultrasonic Sensor and ESP32 or Arduino UNO are quite common. In real life, using an Ultrasonic Sensor for a water tank is often not practical because a water tank can have 1-2 sources of water falling to fill up the tank from the top. Also, with Ultrasonic Sensor, you need to make sure that the position of the sensor is optimum in a way … [Read more...]
The Importance of a Camera Tracking System in Virtual Production
In virtual production, camera tracking is the process of recording the movements of a physical camera and translating them into corresponding movements of a virtual camera within a 3D environment. This allows filmmakers to capture complex shots that would be difficult or impossible to achieve with traditional methods. A camera tracking system is an important tool in virtual production. It allows … [Read more...]
Laser Security System Using ESP32 Arduino
Laser tripwire-based security systems use low-energy lasers and simple technology to trigger the alarm system. This alarm can be auditory, visual or mobile notification via IoT based system. These systems are completely legal in any country till the laser rays are not disturbing the public. On the other hand, a laser fence or laser wall uses a high energy laser (cutting laser) to injure bodies … [Read more...]
What is an Automatic Ethanol Fireplace
An ethanol fireplace is a fireplace for heating an indoor environment using bioethanol, a liquid fuel which can be installed without a chimney and automatic ethanol fireplaces fall among smart devices. The use cases of these automatic ethanol fireplaces are in luxury houses where winter is of short duration such as part of India, North America, Australia and so on. Bioethanol is ethanol which … [Read more...]
Projector Screen Basics
A projector screen is a flat or curved projection surface prepared for projection purposes for viewing the projected image or video from projectors. Modern reflective projection screens have a diffuse reflection property; transmitted light screens for rear projection require diffuse scattering transmission. The projector-screen assembly is one of the so-called objective optical instruments. The … [Read more...]
Zebronics Pixaplay 16 : Entry Level Movie Projector Review
Previously we have published some informative articles on projectors such as Is It Feasible to Build an LCD Projector at Home and What to Look For When Buying a 4K Laser Projector. Laser projectors are a breed of superior technology but most of us can not afford multiple laser projectors at home or office. For various reasons, we need to think about saving money. This article is for helping you to … [Read more...]
How to Do Electrical Layout Plan for Adding Smart Switches
If your electrical connections and switches are not properly planned then your cost to implement smart switches will increase. Installing more than the average number of smart switches will increase electricity consumption. Whenever you are implementing ceiling light, ceiling speakers and IoT; the complexity and electricity consumption is increasing. To keep the electricity bill lower, we suggest … [Read more...]
How to Build a Modern HiFi System
Panasonic, Sony, Akai, Crown and Aiwa no longer sell all-in-one HiFi systems (sometimes they referred to them as home theatre). Although selling the all-in-one "music system" returned good revenue and particularly Panasonic gained popularity for delivering quality systems at mid-range. The all-in-one HiFi systems reduced the required knowledge to purchase each component. The reasons they … [Read more...]
How Internal Pull Up/Down Resistor Works (Arduino/ESP32)
In the context of Arduino/ESP32, we usually add a resistor to the push button to complete the setup. Instead of using a resister, we can define the resister in code. In general, pull-up resistors are the more common simply because that is a thing we need most of the time due to the nature of logic inputs. In this article, we will explain how pull-up resistors work. Pull-down resistors will work in … [Read more...]
What is SIM Swap Fraud? How to Protect Yourself?
SIM swapping is a scam in which someone misuses a mobile phone number for online identity theft. Fraudsters are using this attack to steal money and then the mobile carriers are strengthening their security measures in the checkout lines to avoid it. Increasingly, mobile devices are being used as the primary method for accessing the Internet. One way this is happening is through a user's own cell … [Read more...]
