Linux and Android: What’s the Difference
When purchasing an off-the-shelf module or designing a customized module of your own using a design tool like Upverter (previously known as Geppetto), you have to select an operating system. Often, you have a variety of choices. Two popular open source software (OSS) platforms are Linux and Android. If you’re new to design, how do you know which one you want to use? There are complicated, highly technical answers to this question. However, if you

Open Source Software - A Moving Target
Open Source Software (OSS) is an attractive alternative to proprietary software platforms. There’s a lot to love about OSS. Lower cost is a primary decision driver for many companies. Others want to enjoy the freedom and flexibility to modify the software to their particular application requirements. Some companies don’t want to be at the mercy of the direction—or lack of direction—of proprietary software roadmaps. There’s also a lot to fret over

Crowdsourced Voice Recordings: A Wearable AI Voice Recorder Is Shipping
Use a Senstone and never miss a flash of creative genius again (Image source: Senstone.com) Were you ever a fan of Star Trek: The Next Generation (TNG)? If so, you may recall that the Starfleet officers and enlisted personnel wear small communicator badges on their left breast. These devices are presented in the shape of the Starfleet insignia and are activated with a light tap. They also incorporate a universal translator, which comes in handy

Isolated USB Connection Project
While working heavily with microcontroller projects in the past, I learned that computer USB ports can be fragile things. Simply shorting dozens of volts across the port just kills them dead—and there are so many other creative ways to destroy USB functionality on a motherboard! I’ve seen USB isolation devices on the market which solve precisely these sorts of problems (developers doing bad with their devices), however, I never really got around

SoC FPGA Boasts RISC-V Processor
Well, the current "hot off the press" (don’t burn your fingers") news is that the folks at Microchip Technology have just unveiled the details regarding their forthcoming PolarFire SoC FPGA family boasting a hardened real-time, Linux-capable, RISC-V-based microprocessor subsystem. If you are "in the know," you should be jolly excited by now. On the other hand, there's so much going on these days that it's easy to let things fall through the

Power Consumption Optimization
Power efficiency—energy efficiency if you’re a purist—has become perhaps the highest-profile aspect of system design. This is especially true for IoT applications where a device may need to operate for years on harvested energy or a cell battery. Thus, a critical stage of design is power optimization. Typically, the first stage of power optimization is setting the power budget. For example, the system spec might state that the device has to be

65W Single IC LED Driver Project
One of the projects I’m working on for personal use at the moment is a high color rendering index (CRI) LED panel, which I’m aiming to make about 300W. I was exploring options for making a high-performance LED driver pcb that would be quite compact, and while I couldn’t build a 300W single IC LED driver, I was able to design a 65W one that didn’t look like it would melt right through the circuit board.

Continuous Manufacturing
Volume As a manufacturing term, it can mean different things, depending upon the industry. Volume production for an automotive OEM means hundreds of thousands of units. For an industrial CNC manufacturer, lifetime sales over decades might be in the tens of thousands. For many small design companies, producing even “low” volumes may be a manufacturing challenge. It takes success to be able to invest in infrastructure that supports higher volumes

PCB Bus Routing and Layout: The Basics
Power supply on a network switch Modern computing simply wouldn’t be possible without PCB bus routing and layout. The same goes for many digital systems that manipulate data in parallel. If you’re working on a new PCB design and you need to route a bus between different devices, there are some simple rules to follow to ensure your signals aren’t distorted and that successive devices are triggered correctly. As some designers may question the

High Speed Routing Guidelines for Advanced PCBs
You can create this advanced board with these high speed routing guidelines for advanced PCBs Newer designs are continuing to get faster, with PCIe 5.0 reaching 32 Gb/s, and PAM4 pushing signal integrity and speeds to the limit. Proper interconnect design must account for the lower noise margins of advanced devices, impeccable power stability requirements, and much more to ensure signals can be received properly. With advanced devices running at

Webinar on XR | Think AR on Steroids
Making the business case for XR (Image source: XR Intelligence) Do you remember when the internet first reached the popular consciousness with the release of the MOSAIC web browser circa 1993? A couple of years later, even though almost everyone was aware of the internet by that time, many companies -- including large, multibillion-dollar concerns -- were still debating internally whether it was worth spending their time and resources on having

EMI from Capacitor Heatsinks and What You Can Do About It
Selecting the right heatsink can help you keep your system cool and prevent EMI. While it may not be obvious, or while most designers may not think to check, heatsinks can generate EMI when they are connected to a switching element. This is a common problem in power supply design, and whenever a heatsink is placed in contact with a component that switches with high current draw at high frequency. Reducing EMI from heatsinks requires balancing the
