Review of Eakins V6 microscope camera
Dedicated microscope cameras are often a stand-alone cameras that can output image directly to a display. More robust can also be connected to a PC. Something more than a webcam, yet still not a fully fledged digital camera. In this article I'll be looking at inexpensive Eakins V6 camera of such type.
Quick look at stereo USB webcam and stereo vision
Stereo vision isn't something new. It can be used to get 3D data out of imaged scene which can have various usage cases in robotics, science and alike. Basic stereo vision kit would consist of two webcams mounted in one line with some distance from each other. Rarely you could find pre-built webcams of such type.
In this review I'll look at a stereo-webcam KYT-U200-SNF01ND
that integrates two sensors into one output image that functions as one camera.
Analyzing World of Warcraft multi-core and frequency scaling
How many cores World of Warcraft can use? How many you will need to run this game alongside some other apps like Discord, browser or multiple addons? Let's take a look at cores and frequency scaling of the game and how games can use multiple cores.
Designing a sentiment analysis application for TripAdvisor reviews in Python
Sentiment analysis allows us to quantify subjectivity and polarity of text - of a review, comment and alike. Subjectivity scores a phrase between fact and opinion while polarity scores negative to positive context. In this article I'll show you how to use it to score TripAdvisor reviews but also how to design and implement a simple application with clean code in mind.
Thermal printers for makers and programmers
Thermal printers are used to print bills, tickets, labels and alike in shops and various venues. They are small, cheap and get the work done. But how do they work? What can they print and how to control them?
WoW performance with different RAM configurations
RAM plays a role in game performance. It's quite important for integrated graphics but even with discrete graphics RAM configuration or frequency may affect the CPU performance. Let's check how WoW performance depends on RAM for AMD Ryzen and Intel Coffee Lake systems.
Review of wireless August DVB-T405 tuner for mobile devices
Standard DVB-T tuners aren’t anything extraordinary. They work as intended. USB dongles usually have a signal quality problem when used indoors. However, there is an alternative option - DVB-T tuners with wireless data transmission. They allow you to place a dongle with an antenna away from the device to which it transmits data. In this review I will present just such a tuner - August DVB-T405 .
Ryzen 5 3500X versus i5-9400F in World of Warcraft
AMD or Intel?, many or just few cores? What is better for World of Warcraft? To answer that question I decided to benchmark Ryzen R5 3500X and Intel i5-9400F in a set of WoW scenarios.
Comparing thermals, clocks and performance of R5 3500X and i5-9400F under Linux
Intel versus AMD is a hot topic and there is a lot of benchmarks on the web. I wanted to do a behavior comparison of similar Intel and AMD CPUs - check their thermals, which runs hotter, how do they clock under various loads and which of them will be faster. I've picked two 6 core 6 thread processors – rare Ryzen 5 3500X and Intel i5-9400F. Let's jump into the comparison.
MightMak 60 - small and cheap maksutov telescope
Small and cheap telescopes aren't something providing much value. There are small achromatic refractors that have their own problems with chromatic aberration and cheap plastic finish. But what about a 60mm Maksutov telescope? Lets take a loot at Omegon MightyMak 60.
