LED bulbs we examined are often simpler than those made four years ago, sometimes employing discrete transistors to handle tasks once done via chips. Leland Teschler, Executive Editor Back in 2015, we examined LED bulbs putting out the equivalent of 60-W incandescent bulbs. We recently obtained several new LED bulbs to see how things have changed. The results are … [Read More...]

Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
Basics of cavity resonators
Experimenters beware! If you think it might be instructive to dismantle a microwave oven and power up the magnetron to make a space gun, don’t do it. A microwave gun (called a magnetron) in a state other than as manufactured has numerous potential hazards. (Nevertheless, you can find a lot of YouTube videos describing exactly […]
The electromagnetic rail aircraft launch system, Pt 2: Implementation and issues
Part 1 of this FAQ explored the basics of the EMALS “railgun” technology being implemented for launching aircraft from carriers; this part details the actual installation on a carrier. Q: What are the various subsystems the EMAL system? A: The overall design has six major functional blocks, (Figure 1). The Prime Power Interface, which is […]
The electromagnetic rail aircraft launch system, Pt 1: Objectives and principles
The traditional and battle-tested steam-powered catapult used to launch aircraft from carriers is being replaced by a powerful, electromagnetic-based, closed-loop linear-motor system — maybe. For over seven decades, the steam-powered catapult has been the standard mechanism for launching airplanes from the decks of aircraft carriers, with an associated cable-tensioned brake used for arresting them on […]
Part 2: Winning with a sustainable PDC management process in embedded systems design – 12 steps
In part 1, we provided an overview of the product life cycle (PLC) and product development cycle (PDC), noting their distinct differences. In this second part, we will explain in detail the 12 steps of the product development cycle (PDC). Figure 1 shows the typical flow chart of a PDC management process and the 12 […]
Winning with a sustainable PDC management process in embedded system design (Part 1)
This is the first in a three-part tutorial series explaining how to implement the product development cycle process. Nearly everyone knows Microsoft Excel. Fewer know Lotus 123, and almost no one remembers VisiCalc, the first version of a spreadsheet computer program for personal computers, which ran on the Apple II. There have been a few […]
Simplifying product returns through device security
by Oivind Loe, Chief Technology Officer, Sipsby.com, and Josh Norem, Staff Systems Design Engineer, Silicon Labs Product returns for Internet of Things (IoT) devices can be challenging. On the one hand, connected the device should be locked down as much as possible when going out to the field. On the other hand, when a device […]
Why it’s tough to characterize SiC power MOSFETs
Switching transients and parasitics can combine to thwart the accurate measurement of important MOSFET operating parameters. Levi Gant, Xuning Zhang, Ph.D., Littelfuse, Inc. Silicon carbide (SiC) power MOSFETs get a lot of attention because they can switch fast while maintaining high blocking voltages. But their superior switching qualities also have potential drawbacks. Parasitic inductances caused […]
The difference between CCD and CMOS image sensing
Charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) technology have been in fierce yet friendly competition. Fierce because valuable market share is contested, friendly because the rival digital camera technologies have much in common. It is ironic that the more-costly CCD sensor is used in the most advanced astrophotography instruments and also in low-end point-and-shoot cameras, […]
