- [转载]Arduino prototyping
- Arduino prototyping This is a design for an open-source prototyping shield for Arduino NG/Diecimila. It has tons of cool features, to make prototyping on your Arduino easy. Compatible with NG or Diecimila Reset button up top ICSP header Lots of GND a ...
- Relay Module interfacing with Arduino and NI-DAQ
- Relay Module A relay is basically a switch which is operated by an electromagnet. The electromagnet requires a small voltage to get activated which we will give from the Arduino and once it is activated, it will pull the contact to make the high voltage circuit. The relay module we are going to us ...
- [转载]Image Segmentation Using Color Spaces
- It may be the era of deep learning and big data, where complex algorithms analyze images by being shown millions of them, but color spaces are still surprisingly useful for image analysis. Simple methods can still be powerful. In this article, you will learn how to simply segment an object from a ...
- [转载]Understanding your Electrical Service, 120V vs. 240V
- When performing home inspection many times I will have discussions with my clients on the home’s electrical supply and how it is wired. Out of this it was apparent that most people do not have a basic understanding of how electrical power is distributed to and throughout the home. And ...
- [转载]OpenCV GPU CUDA Performance Comparison (nvidia vs intel)
- In this post I am going to use the OpenCV’s performance tests to compare the CUDA and CPU implementations. The idea, is to get an indication of which OpenCV and/or Computer Vision algorithms, in general, benefit the most from GPU acceleration, and therefore, under what circumstances it might be a ...
- Build OpenCV4.0.1 contrib modules with Cuda enabled
- General configuration for OpenCV 4.0.1 ===================================== Version control: unknown Extra modules: Location (extra): D:/Software/Programming/OpenCV/ opencv_contrib-4.0.1/modules Versi ...
- [转载]Qt Has a Solution for All Your Timing Needs
- You have probably used the QTimer class for basic timing operations in Qt. Common use cases include polling for events (not always a good approach, but sometimes necessary), updating the user interface or performing some other function at regular intervals. And you probably know about t ...
- [转载]Hall Effect Sensor with Arduino
- How to Use a Hall Effect Sensor With Arduino Have you ever wanted to make a project that involved contactless sensing, for example, to detect a door closing, count the number of revolutions of a wheel, or make a speedometer? Then this Arduino Hall effect sensor tutorial ...
- [转载]Machine Learning vs Statistical Learning
- There is a subtle difference between statistical learning models and machine learning models. Statistical learning involves forming a hypothesis before we proceed with building a model. The hypothesis could involve making certain assumptions which we validate after building the models. ...
- [转载]Hydraulics vs Pneumatics
- In the world of fluid power application, the difference between hydraulics and pneumatics are often comprehensively covered. These two kinds of power circuits are actually similar in a number of ways in that they both use a fluid to channel mechanical energy as well as in the executions, t ...
