DIYA UAV Vision tracking system based on Raspberry Pi and PythonThe drone's image is stored and transmitted to the ground station in real time, which is almost standard. Suppose you want something advanced--to process the captured image directly on the drone and implement your own active control. In fact, visual tracking has been in some high-end consumer-class UAV has the application, just play out of the box and never have their own hands-on;).Some time ago DIY a UAV three-axis gimbal Vision T

Python now gives the feeling is big, the thing is many, after installs in the Windows unexpectedly to occupy 100 megabytes of space. Lua feels very small and light. Python 2.7 Code compiled under Linux also has more than 3M after strip, earlier versions should be smaller, but there should be seven hundred or eight hundred trillion. So does python not compile a lightweight, small-sized code? The answer is no, here are a few Python variants to see how small python can be.1, PymiteThis is a python

Fritzing is a set of software designed for PrintedCircuitBoard printed circuit boards. It is a tool especially intended for designers, artists, researchers, and amateurs. Like Processing and Arduino, Fritzing developers design this software in the spirit of openness, simplicity, and sharing. Fritzing is a simple and easy-to-use software operation interface, this allows users to easily design PCB printed circuit boards without the background of an elec

Using the processing software, through the Arduino input electronic compass data, through the PC side calibration, the program is as follows:Import processing.serial.*; Serial MyPort; arraylist//x Line (Midx-100,midy,midz,midx+100,midy,midz); 　　Y Line (Midx,midy+100,midz,midx,midy-100,midz); Z Line (midx,midy,midz-100,midx,midy,midz+100); Box (200); for (int i = 0;i　　The Arduino code is as follows

This article uses the latest Penetration tool RFID snitch (Tastic RFID thief) and RFID induction hack technology to gain access to some buildings that have security.Tastic RFID Thief is a silent long-range RFID reader, can not be known to steal RFID information far away, when an unsuspecting person wearing an access card or radio frequency equipment, it will be breached. Tastic RFID thief for low-frequency 125KHz RF systems, such as those using HID ProX or Indala ProX, not only that, You can als

the working mechanism of ROS: Simply put, Ros is a DistributedThe operating system communicates and controls through node nodes, subject topic, service services, etc. This mechanism is like two people chatting, everyone is a node, this software chat function is topic, two people only through to chat, if a person with whatsup, another person with, is not receive the other party information. And the service is like the expression pack or the circle of friends, two people chatting at t

a UART-to-do its serial communication. For those familiar with the Arduino, the Tx/rx pins on an Arduino is the the and the main UART pins. In its more basic form the UART hardware consists of a transmit (TX) line and a receive (RX) line. The software configures how fast data was sent (the baud rate) and the specifics of the protocol.Baud Rate　　Since The UART module is asynchronous, there are no external c

Late 1,Flash storage: In the Easyflash to increase the log storage, read function, so that Easylogger and its seamless docking. So that the log can be stored more easily in the non-file system , and has the function of historical day retrieval; 2, configuration file: File system under the configuration file; 3, File transfer: File system supporting files according to the c

Since the first set of mechanical keyboard, has modified the interface scheme, installed LED lights, etc., but always can not meet their DIY desire.So the simplest way to think of it is to use a ready-made master, and the master comes from an abandoned keyboard, such as:This master control is also the matrix mode, only need to measure the corresponding key and then weld the line, complete the diagram as followsUsing the O 5-foot red axis mechanical shaft.
