The tourbillon is a device in which the oscillation and escapement system of a mechanical watch rotates on its axis in order to achieve less positional accuracy, especially in wristwatches and pocket watches. Due to gravity, the accuracy of conventional watches is not the same in all positions. A tourbillon distributes the effect of gravity on the oscillating system evenly over all positions of at … [Read more...]
What is Binaural Sound Recording?
A binaural sound recording is a sound recording of sound signals with microphones that are intended to create a natural auditory impression with precise directional localization when played back only through headphones. When recording in artificial head stereophony, an artificial head is often used. In the past, the term binaural was often equated with stereo. In general, stereo sound … [Read more...]
Typical Characteristics of RISC Processors
Reduced Instruction Set Computer (RISC) is a design philosophy for computer processors. The design goal was to dispense with a complex instruction set that was convenient for assembly programming in favor of instructions that were easy to decode and quickly execute. This also allowed for higher clock speeds. The design philosophy opposite to RISC is called the Complex Instruction Set Computer … [Read more...]
What is Digital Signal Processing (DSP)
Digital signal processing is a branch of communications engineering and deals with the generation and processing of digital signals with the help of digital systems. In a narrower sense, its focus is on the storage, transmission and transformation of information in the sense of information theory in the form of digital, discrete-time signals. It has diverse and far-reaching applications in today's … [Read more...]
ESP32 Neopixel Ring Clock
Previously we have published a few articles on Neopixel Ring, such as spindicator/chase effect with NeoPixel ring. Also, we have published one article on Get Time & Date From NTP Server (you can read about NTP server here). If you combine these two principles, you can build a simple clock based around an ESP32 Arduino to fetch time from an NTP server and a Neopixel Ring to display hours, … [Read more...]
Creating a Logo Style Guide for Consistent Branding
Keep in mind that your brand’s logo is its visual representation. Your brand’s logo is what your customers will spot first when they encounter your business, and it's what they’ll remember long after they’ve forgotten your company’s name. That’s why it’s significant to have a strong logo that’s not only memorable but accurately reflects your brand identity as well. But once you have a great … [Read more...]
Variants of Predictive Analytics
Predictive analytics uses historical data to predict future events in finance, meteorology, security, economics, insurance, logistics, mobility, and marketing, among others. Generally, historical data is used to create a mathematical model that captures key trends. This predictive model is then applied to current data to predict what will happen next or to suggest actions that can be used to … [Read more...]
What Activities Can be Automated in Testing
Test automation is the automation of activities in testing, both software testing and hardware. In software development, it is particularly important to know a fixed, defined status of the software, such as: Is the current, new software version better than the old version? Automatic tests, which test for undesirable effects on other functions after a change has been applied, are called … [Read more...]
Types of Software Requirements
A software requirement is a requirement in the context of software development. The request captures the purpose and intent of a software system, as well as its (external) behavior. The task of the requirements manager is to collect the requirements and possibilities together with the stakeholders involved and to transfer them into a form that is understandable for software developers. This is … [Read more...]
What is Refusal to Consume
Refusal to consume refers to the behavior of consciously avoiding the use of available goods. It ranges from frugality to asceticism. It can cover the whole lifestyle, but it can also be limited to certain goods (food, clothing, home comfort, etc.). The refusal to consume is the most important element of a simple life. Accordingly, there are personal, social, religious, ethical, ecological, … [Read more...]
Digital Camera Back (Film to Digital Camera Conversion)
Often people ask for details on the conversion of film cameras to digital cameras. Digital camera backs contain image sensors for digital image recording. They are attached to the back of modular analog camera housings and extend the corresponding camera system into a digital camera system. They are mainly used in the field of medium format and large format cameras. In the case of medium format … [Read more...]
