1. What is the dragon core open source motherboard?
For all, the 3D printer maintains extremely high exposure in China, any news, but there are "3D printing" words, click rate is absolutely low. In addition, there are many foreign news about 3D printing, such as print pistols, planes, teeth, burgers, etc., so that many of the pole is full of curiosity to this artifact, always thinking that there is a day to have it, a big job. This is not, the nearest news makes us oscillating, based on the "Open source dragon core mother" of Longxin 1C SOC chip has begun to make booked, and developed "Dragon Indus" Delta 3D printer based on this basis, most The key is that this program is extremely high, and the entry-level price is expected to be around 1,000 yuan. is this real? Really? Really?
Is the thousand dragon core 3D printers are creative or flicker?
What is the dragon core open source motherboard?
It is a dragon core embedded motherboard that is promoted in an open source. It is integrated with the "Raspberry Pivot" as the postcard size board integrated dragon core 1C SOC, NIC interface, USB interface, power supply, SD card slot and RTC Main components such as clocks can run embedded Linux systems to achieve various applications. The chip used by the motherboard is affiliated to the No. 1 family. Based on the LS232 processor, the chip uses a low-cost QFP package to cater to the low-end market, and the hardware engineer can handle itself, without machine patch, facilitate learning and shorten the development cycle, saving costs. A large feature of the Open source dragon core is to support multiple open source hardware extensions, which can use Arduino, Microduino, XBee extension modules, mainly object-oriented is dragon core enthusiasts, student, creative guests, embedded developers.
Simply put, this goods can also be called the development board / single-chip / card computer, integrating quantity of amazing I / O interfaces on the 85mm × 56mm size motherboard, plus Linux-based characteristics make it playable, educated The practicality is quite strong. Anyone with Linux-based people can accomplish a variety of special functions by using it, complete a variety of computer tasks, and relying on volume, and power consumption.
Open-source dragon core mother compared with the existing "Raspberry Pivot", Arduino, in realizing the overall cost of network camera, access to the Internet, wireless gateway, the extension interface is really rich, almost omnus Pack, so suitable for project development of smart home wireless gateways, webcams. The motherboard is self-selling price of 199 yuan.
However, in terms of performance, this car can be opened several streets by the opponent. According to the official information, the leader is only 300MHz, the process is 130nm, and the memory is 8 / 16bit. How many years ago, I really have thought it. Take a look at the Raspberry Passenger 2, the processor is the main frequency 900MHz blog BCM2836, there are four Cortex-A7 architectural cores, built-in 1GB LPDDR2 memory, 28nm programming, price of only 35 US dollars. This gap, the drum is also caught up.
2. What can I do with a thousand yuan 3D printer?
Do you have a few hundred pieces of merits?
For many intelligent hardware entrepreneurial teams from the software and the Internet industry, only Internet thinking is not enough. If you design the hardware motherboard, the development cycle and cost cannot be controlled, but you choose an open source motherboard, fast implementation is very Suitable methods, the results of opening source motherboards are free to use, which can greatly reduce the initial research and development costs. If you have no concept, then look at the application of the Raspberry School, this goods and open source dragon core mother are similar, Jingdong price is 299 yuan, Taobao is less than 200 yuan.
Using Raspberry PC-controlled rotor aircraft, you can equip the micro-camera for smartphones, a combination of aerial photographing relative to ordinary rotor aircraft + cameras, not only cost, but also achieve more complex features, such as aerial photography or real-time aerial photography Image wireless transmission.
Raspberry Pieces include a motherboard and a plastic box, the motherboard is connected to the Raspberry PC, and the plastic box is used to connect the high-grade wooden block. After installing the battery, you need to add the motor and sensor for the Lego robot, and finally load a demonstration program for initial control. Absolutely crazy hanging sky.
It is also aircraft, but the function of the Raspberry Pie is not controlled. Hydrogen balls go straight to space, need it to collect data, take a photo, low cost, no greenhouse gas, are you still launching a rocket?
At present, Longqin Club has launched a number of open source hardware demonstration projects based on open source dragon core main boards, such as network-class dragon core wireless home sensing gateways, control class four-wheeled cars, robotic arm, human-machine dragon core network digital frame, etc. It also includes a 3D printer. Maybe everyone thinks about the 3D printer too complicated and mysterious. In fact, I have already "800 yuan assembled a 3D printer full tutorial on the Internet". Taobao has a 3D printer assembly kit, all of the electronic devices They all match you, the price is only 999 yuan.
What can thousands of 3D printers?
According to the information we have now, the 3D printer of the code "Dragon" is already in design, which will use faster and more stable delta printing structures. The mechanical structure of the usual 3D printer is the movement of the material plate responsible for the up and down direction, and the movement of the front and left and left directions is completed by the print hot head, while the printing hot head of the three-parallel arm 3D printer is also responsible for 3 directions. Another difference is that its feed motor is fixed on the shelf, not moving with the hot head, making the inertia of the hot head greatly reduced. Since its structure is triangular, it is called a "delta" printer.
Industry insiders said that "Delta" 3D printers can only be said to be a senior toy. First, it is controlled by the cost, the frame is lighter, and the resonance is generated under high-speed operation, which affects printing accuracy. Second, the size is small, only small objects can be printed. Third, based on the dragon core open source motherboard, the calculation capacity is serious, and when printing complex models, a stuck phenomenon is likely to cause small sputum to produce a small spot, affecting the beauty of the print.
This year, I am most afraid of being a brick home that I know. Now everyone understands, in fact, the dragon core open source motherboard just wants to use 3D printers to speculate, lienopia, and practicality is not high. Of course, if you are a trench, you can buy a home, nothing DIY mobile phone case, self-entertainment.
