Optocouplers not only protect sensitive circuits but enable an engineer to design a variety of hardware applications. Optocouplers can avoid a great deal of cost in replacing components by protecting them. However, optocouplers are more sophisticated than fuses. Optocouplers also make it convenient to control the connection between two circuits by connecting and disconnecting them […]
BGP hijacking: How the Internet is getting hacked and what you can do about it
By Rudy Ramos, Mouser Electronics Most of us are familiar with the tricks used by malicious hackers to steal passwords or intercept private data. When we click a link, or start a chat, or send an email, it’s second nature to quickly check URLs and addresses to make sure that our data is going where […]
Robots are getting in touch
by Rudy Ramos, Mouser Electronics Often overlooked is the value of a sense of touch in robotics development. Designers focus strongly on discrete features such as power, freedom of movement, and machine vision. However, tactile sensing complements all of these and helps make the most of them. Having a sense of touch also adds unique […]
Free PCB footprints, schematic symbols and 3D models now available from Mouser
Mouser Electronics, Inc. has announced a new partnership with SamacSys. Under the new partnership, Mouser will provide its customers with a range of free design resources including PCB footprints, schematic symbols, and 3D models for more than 1.1 million components. These design resources work seamlessly with top engineering CAD systems, including Cadence, Altium and other programs. The […]
What are diodes? A quick refresher
A diode is a passive component made with semiconductor materials (a chip) that conducts current flowing in one direction but does not conduct current flowing in the opposite direction. The symbol for a diode (to the right in Figure 1) looks something like an arrow pointing in the direction of the forward current. Current flows […]
The changing face of medicine
by Rudy Ramos, Mouser Electronics Medicine and healthcare is one thing that matters to every single person on the planet. We all, to a greater or lesser extent, care about our health — whether it is to attain peak fitness, look for early signs of an issue or monitor / manage a long-term health condition. […]
Will AI and automation make work completely obsolete?
By Rudy Ramos, Mouser Electronics Almost 4 million US workers could eventually be displaced by autonomous vehicles, according to a US Department of Commerce report. While the report, “The Employment Impact of Autonomous Vehicles,” does not offer a firm timeline for job losses, it seems to be the latest evidence of a future in which […]
Modern factories: Electromagnetic noise is replacing audible noise
by Rudy Ramos, Mouser Electronics In the past, factories were noisy places; in fact, noise-induced hearing loss was one of the most common occupational ailments in the USA. As the Industrial Internet of Things (IIoT) – sometimes termed Factory 4.0 – led to more electronics in factories, electromagnetic noise replaced audible noise. As the need for process […]
How can you get a ballpark price for a sensor in a new design?
Pricing is one of the top criteria for selecting one sensor supplier over another and often for specifying a specific sensor over another for a new design. Some sensor companies, such as semiconductor companies that supply microelectromechanical systems (MEMS) and other semiconductor-based sensors, have a buy page on their website with low volume pricing. For […]
Selecting an op amp
You could start with a similar op amp from a similar, known-good circuit or reference design and extrapolate from there. However, not everything labeled a reference design has actually been built and tested. But there’s another way to get organized and feel in control of the selection process. A methodical approach is outlined below that […]
