Deliverance from illusions

I have long wanted to find a job related to the development of 3r3r78. CAD [/b] programs. Because it is interesting to me and because I have a lot of experience in this field (20 years). And in 2010 my dream came true and I got even more than I wanted.
 
And the first time I just fought in ecstasy. Favorite work, the opportunity to work at home. I had ambitious plans! At the very beginning I sketched this plan for myself in writing Cobalt Next Steps.
 
At the end of last year, Robert Bou, owner of the company

DDR SDRAM - design features and signal integrity

DDR SDRAM - design features and signal integrity  3r3118.
 3r3118. 3r3111. Designing electronic devices using fast DDR SDRAM memory modules requires special attention to the problem of signal integrity. The article describes the modern modeling tool for solving such problems. 3r33112.
 3r3118.
3r314.
 3r3118. Today, almost all modern electronics are equipped with memory modules. Servers, computers, smartphones, game consoles, GPS-navigators and most other devices are designed based on processors and FPGAs. Such devices require high-speed, high-bandwidth memory or dual frequency data transfer (DDR) memory. With each new generation of DDR SDRAM (synchronous ...

Single-stage gearbox with drive from Stepper Motor

In this post I want to talk about the production using a previously made by me CNC machine with a single-stage straight-through gear.
 
Single-stage gearbox with drive from Stepper Motor  
 
gantry CNC machine , about its development and construction on this resource is located my previous article.
 
Just want to say that this project serves only to gain experience in designing simple gear pairs and their manufacture for possible application in subsequent projects.
 
 
Since on the machine tool it was planned to process not only wood and plastics, but also dural, it was interesting to make a gear pair just from this material.
 
 
By the availability...

Modeling of the Sagnac effect by the methods of geometric optics

Modeling of the Sagnac effect by the methods of geometric optics
 
High-precision inertial navigation systems (INS) are one of the most high-tech elements of the modern aerospace and military industry. The task of such systems, built on the basis of accelerometers and optical gyroscopes, is the determination of angular velocities, accelerations of a moving object, and, in general, the orientation of the object in three-dimensional space.
 
The specific feature of the ANN simulation is that in the modeling domain, both rectilinear and rotational motion often occur, which strongly affects the operation of these systems and, accordingly, requires accounting. In this article we ...

FreeCAD - a new method of drawing

FreeCAD - a new method of drawingDisclamer
: I've never worked with CAD /CAM applications in my life before, and, suddenly, I had to. The principles of the work of FreeCAD have so delighted me that it requires an urgent post on Habr to tell others.
 
Written in this post, it is likely to be trivial and boring for most active CAD users, and this post is aimed primarily at non-CAD users in order to tell them about the wonderful new world of computer graphics.
 
Introduction
 
I had a simple task - to make a 3D model of my apartment. Not just the "walls in size", but all the beams, ledges and bends. I tried one, the second, the third ...

Large portal milling machine with CNC with their own hands

Hello dear reader, in this article I want to share my experience building a milling portal machine with numerical program control.
 
 
Large portal milling machine with CNC with their own hands  
 
There are a lot of similar stories in the network, and I probably will not surprise anyone, but maybe this article will be useful to someone. This story began at the end of 201? when I was accumulating a certain amount of money with my friend, a partner in the development and production of test equipment. In order not to just skip the money (it's something young), they decided to invest it, after which the idea of ​​manufacturing a CNC machine came to mind. I already ...

Modeling of vibrations and noise in the transmission of the car

Modeling of vibrations and noise in the transmission of the carAt the work the transmission used for transfer of energy from the engine to wheels, strongly enough rustles. The first reason for this undesirable effect is that the transverse and axial forces resulting from the transfer of energy from one shaft to the other by means of a pinion have an undesirable mechanical effect on the bearings and the housing. The second reason is the flexibility of the various components of the gearbox, including bearings and housing, which can also lead to vibration. The variable stiffness of the gear clutch in the gearbox causes a constant vibration transmitted to the ...
