ESP32 MAX30102 Pulse Oximeter Code
In the previous guide of MAX30102, we have shown a test code with the MAX30102 module build/sold by Maker Focus mounted on a MH-ET LIVE breakout board. Our two challenges are - ESP32 is not exactly same as Arduino UNO and the good looking MH-ET LIVE breakout board is not same as the MAX30102 module sold by Sparkfun. As we commonly use the MAX30102 sensor library by Sparkfun, we need to guess which … [Read more...]
Pulse Oximeter with ESP32 and MAX30102
The MAX30100 IC is an integrated pulse oximetry module two LEDs, a photodetector, optimized optics, and low-noise analogue signal processing designed for the wearable devices and medical devices. The MAX30102 IC is an upgrade to The MAX30100 and The MAX30101 IC. Here is the datasheet of MAX30102 (website of MAXIM). The PDF will give you the outlook of the working principle of the thing. … [Read more...]
DIY Power Bank With TP4056 and MT3608 (3.3V to 12V)
For any electronics project, we require a power source. In our previous article How to Run an ESP32 on Battery, we have discussed about the challenges with direct powering with battery. As most of the projects require 3.3V DC to 5V DC, we need some system which can be charged with a mobile charger and the output voltage can be adjusted for different configurations of the power supply plans. … [Read more...]
Advantages and Disadvantages of Convertible Laptops
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...]
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...]
Technologies in the 3D Slot Game Industry
There is no way to deny that, over the last handful of years, slot machines and server-based gaming have had a huge makeover. The industry has been advancing at a tremendous speed, and opportunities for the software developers are increasing. Now not only can they be played in pubs, clubs, and casinos, but they can also be played online in virtual casinos, and the gameplay is just the same as it … [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...]
