New Auto Safety Technologies Push Repair Bills Up – IEEE Spectrum

https://spectrum.ieee.org/riskfactor/transportation/advanced-cars/new-auto-safety-technologies-pushing-repair-bills-upwards There is little debate over whether advanced driver assistance systems (ADAS) could reduce both the number and severity of vehicle crashes. A collision-mitigation system alone can increase the cost of a new vehicle by US $1,500 or more and vehicles equipped with advanced safety features “can cost twice as much to repair following a

Is Kubernetes The New Application Server?

You might have noticed that many widely used languages are interpreted and use “runtimes” to execute your source code. In theory, most Node.js, Python, Ruby and Java. Theoretically code can be easily moved from one platform (Windows, Mac, Linux) but usually there are problematic issues caused by factors external to your application. Why Kubernetes is

Samsung J5 smart phone teardown

Here is teardown of a broken Samsung J5 smart phone (SM-J510FN from 2016). Let’s open it: A Closeups of circuit board Not too much to see. Many parts were covered with metal cases soldered to circuit board. I did not see here any easy to fix problems (like loose connector) that would have allowed to

More measurement on Potato TDR circuit

This is a continuation to my recent potato chip to TDR circuit posting at http://www.epanorama.net/newepa/2018/10/16/potato-chip-to-tdr-circuit/ Here are some measurement results made with high speed oscilloscope (at shortest pulse setting and 50 ohms impedance). Blue measurement with circuit directly connected to scope and yellow wirh 10x scope probe.

Switched-mode power supply tutorials

A switching-mode power supply (SMPS) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight are required. The main advantage of the switching power supply is greater efficiency than linear regulators. The downside of
