Open source 3D printer RepRap

图片
RepRap is a 3D printer prototype (or 3D printer), which has a certain degree of self-replication ability and can print out most of its own (plastic) components. RepRap is the abbreviation of (replicating rapid prototyper). This prototype is free and open source from software to hardware, and is released under the free software agreement GNU General Public License GPL. RepRap is a 3D printer designed and manufactured by Adrian Bowyer and others from the University of Bath, UK. It differs from the traditional flat printer in that it prints three-dimensional objects instead of flat surfaces. Yes, its printing materials are not ordinary ink, but ABS plastic, polycaprolactone, etc. The original design goal of RepRap was for a very sci-fi purpose. It kept copying itself, and it was only some mechanical parts. This is also the origin of its name-RepRap is short for Replicating Rapid-prototyper. RepRap can also be used to make things other than its own parts, such as door handles, coat hooks,

Pros and cons of IDC connectors

图片
IDC connector series products existed as early as 1950, and are a recognized design type. Many manufacturers provide a wider range of design and processing options, which was accepted by people at that time and can be used in various lines Gauge, pin size and centerline. After knowing the origin of the IDC connector, next, Konnra connector engineer will give you the advantages and disadvantages of IDC connector. Konnra connector engineers pointed out that IDC connectors, also known as insulation piercing contacts (IPC), are one of the common electrical connectors and are mostly used to connect to conductors of insulated cables. This connection process will force the selectively sharpened blade to pass through the insulation layer without removing the insulation conductor before connection. After being properly fabricated, the connector blade can be cold welded to the conductor, thereby achieving a reliable and gas-tight connection in theory. 1. What are the advantages of  IDC connector

The principle of 3D printer

图片
3D printing, like laser forming technology, uses layered processing and superimposed forming to complete 3D physical printing. The printing process of each layer is divided into two steps. First, a layer of special glue is sprayed on the area to be formed. The glue droplet itself is very small and is not easy to spread. Then, spray a uniform layer of powder. The powder will quickly solidify and adhere to the glue, while the area without glue will remain loose. In this way, the solid model will be "printed" under the alternation of a layer of glue and a layer of powder. After printing, the model can be "planned" as long as the loose powder is swept away, and the remaining powder can be recycled. The original 3D printing seems complicated, but it's actually very simple After watching a lot of 3D printed videos and models, you will be stunned by its magical cloning ability. This is amazing. It is a magical clone machine. How does such high technology work? Speaking

The key to this is the performance of nickel. It makes the connector products more reliable, and also allows gold-plated connectors to have the following four functions: 1. Leveling layer The nickel base plate can be used as a leveling agent, which can produce a surface roughness with l

11 misunderstandings about USB Type-C

图片
1. USB Type-C and PD are complicated When using a universal connector that can be plugged into a power supply or device, negotiating which device powers which device seems to be intimidating for product designers and consumers. However, the complexity of the product can vary according to the needs of the product designer. For devices that only support Type-C, an integrated circuit (IC) can be used to perform this negotiation and connection. For more complex features, a power supply protocol (PD) can be implemented. To achieve USB-C PD compliance, a series of strict guidelines must be followed. Product certification must be reviewed by the USB-IF Regulatory Committee. The use of firmware from certified IC vendors can simplify solution design. 2. USB Type-C and PD are expensive In order to detect, connect, and negotiate communications, the move from USB 2.0 to USB-C seems expensive. For basic USB-C functions, a state machine controller can be used. The price of this controller in the mar

Latte Panda—a powerful computer with a small figure

图片
LattePanda (124-4684) is a single board that integrates a Win10 computer system and an Arduino compatible core, which is slightly larger than the Raspberry Pi. Obviously we cannot ignore the similarities between LattePanda and Raspberry Pi. Indeed, the markets targeted by the two are similar, but the "tastes" are different. Unlike the Raspberry Pi which uses the Linux system, LattePanda uses the Win10 operating system. This board uses a powerful 1.8GHz Cherry Trail Intel Atom CPU (Z8300) to provide a great Windows desktop experience. Without the Intel Atom processor, the I/O port is controlled by another microprocessor. However, when the requirements of the application are high, this microprocessor can also be reprogrammed to offload the Atmo processor. In terms of performance, the Atom Processor is not like the Atom CPU. It sometimes has a load, and its specifications are more similar to those of modern netbook processors. These specifications are based on the calculation st
