Traditional laptops are portable enough but many of us are now used with touch and pen interface because of the penetration of the smartphones. The tablets with an i7 processor are just too damn expensive. Within a budget of $2,000, convertible laptops with 2K to 4K displays are simply ludicrous. The convertible laptops are designed for the budget-conscious audience who do not need a graphics … [Read more...]

HP Pavilion x360 i7, 14 Inch (14-cd0055tx) Review
HP Pavilion X360 14-CD0055TX was launched in 2018 and is a discontinued model now. The marked price on the box was $1300 (98,000 INR). I grabbed the unopened box-packed convertible laptop with 4GB NVIDIA graphics card, 8th generation i7 processor from a big-box retailer (Reliance Digital) with a "last piece" tag at $850 (63,000 INR). It has a 14.00-inch display (2K display, 1920x1080 pixels IPS), … [Read more...]
Fix : Missing B&O Audio App in HP x360
Your problem is - you have re-installed Windows 10 or got some update and B&O's icon has been vanished. You are searching the whole internet including HP's forums to get it back. None can fix your issue. Before reading the fix, you need to know some facts. History of HP's Audio Managers Bang & Olufsen (B&O) was a high-end electronics company who designed a radio to … [Read more...]
Does Intel Optane Memory Module Work?
These days especially for the laptops, the salespersons will tell you "This model has 16GB of Intel Optane Memory. You can upgrade it to 32GB." Intel Optane memory module is the worst form of pushing a thing before which there is a lot of hardware needs to get upgraded. A computer's performance becomes better with more amount of faster RAM (right now that is 16GB to 32GB), a faster SSD and a good … [Read more...]
Required Theory For Unlocking Cars With Smartwatch (ESP32 Arduino)
In this article, we will discuss the opportunities to add a BLE controlled system of ESP32 in parallel to the central lock fitted by the company which will unlock and lock our cars based on proximity of our smartwatches. Our regular readers already learned how to use ESP32 Arduino with a buzzer to detect a Samsung Smartwatch. Also, they can track such events on IBM IoT dashboard. The car's … [Read more...]
ESP32 as Hardware Random Number Generator
The capability of the ESP32 to generate truly random numbers is important for cryptographic operations. A random number generator generates a sequence of random numbers. A hardware random number generator is also known as a true random number generator. It generates random numbers from some physical process, not from code. A fundamental distinction is made between non-deterministic and … [Read more...]
How Server-Based Gaming (SBG) Works
The casino industry uses the server-based gaming (SBG) hardware system to operate Video Lottery Terminals slot machines. General non-casino gaming systems differ from the casino systems in various ways. Server-Based Gaming (SBG) is built upon the server-centric gaming technology borrowing the principles from thin client. Reliability, scalability and stability are few of the requirements in the … [Read more...]
IoT IR Remote Control with ESP32 Arduino and IBM Watson IoT
In this article, we are discussing the overall hardware, code and library we will need. This article is not about building one particular project. Infrared (IR) remote control technology is widely used in day to day used devices. IR remote control signals are a reliable resource to control nearby electrical appliances. With the development of ESP32 like cheaper system on chip and Internet of … [Read more...]
How to Run an ESP32 on Battery
The operating voltage range of ESP32 is 2.2V to 3.6V. The ESP32 boards have an LDO voltage regulator to keep the voltage at 3.3V. The output of the regulator is also broken out to one of the sides of the board and labelled as 3V3 which can be used to supply power to the other components. The VIN pin can be used to directly supply the ESP32 a regulated 5V voltage electricity supply. In other words, … [Read more...]
ESP32 vs Arduino : How ESP32 is Different from Arduino
ESP32 is a low cost, low power consuming System on Chip (SoC) with integrated Wi-Fi and Bluetooth compatible with Arduino IDE. In other words, an ESP32 board can be used as "Arduino" following some guide like we have published one in the past. ESP32 is developed by Espressif Systems and has a Tensilica Xtensa LX6 microprocessor. By the phrase "Arduino", we mean the boards which are designed and … [Read more...]
ESP32 Arduino Smartwatch Detector with Buzzer
The series of article Samsung Smartwatch as Proximity Switch taught our readers to learn all required the basic to make ESP32 to respond to a specific smartwatch's BLE. The same basic was used for the IoT project Detect Smartwatch With ESP32 on IBM Watson IoT Widget. But, still today in everyday life we depend on sound clues more than the visual clues. A door bell or a smoke detector are some … [Read more...]
