Creating a Powerful 150W DIY LED Driver for Driving Large Lighting Panels Most of my recent projects have been working towards building a high CRI (Colour Rendering Index) light panel for cinematography. A good quality video light panel is expensive, and for good reason, but as a maker, I tend to like buying things instead of just buying them. My goal was to build a 300-320W panel. However, I’ve come to realize that the limitation for a panel with that many LEDs is not driving them, but instead reflowing the board.

Read Article Reduce PCB Manufacturing Time Through Manufacturer Collaboration In a recent interview with PCB007, Altium VP of Marketing Lawrence Romine recalled a brief conversation with Tara Dunn, who remarked that all designs her company receives for manufacturing get put on hold. If you’re a manufacturer, this probably doesn’t surprise you; some designers can be very cavalier with their design choices. Although these designs may be innovative and useful from a signal integrity and layout perspective, they may not be Read Article USB Charger Project in Altium Designer: Part 2 In a previous blog post, I showed the process for building a schematic for a custom USB charger board using Altium Designer. This board requires a small number of components and some particular attention to the USB power supply design/decoupling networks, but aside from this it’s quite easy to build out the connections you need for the USB A connectors. Here, I’ll show the strategy for translating this schematic into a compact board with a small Read Article USB Charger Project in Altium Designer: Part 1 When I’m in my office, I keep my pluggable USB charger around, otherwise the battery on my phone is likely to run out. If you want to build your own USB charger, you can create your own USB charger board with the powerful schematic design and layout tools in Altium Designer. Here, I’ll present the overall design process for a portable USB charger. The charger requires 12 V of power and charges two external devices through two USB ports. We’ll Read Article Understanding Your PCB Netlist File Understanding Your PCB Netlist File There are several different ways that PCB netlists are used at various stages of the electronics development process. Netlists may have different purposes and may have unique data formats, but they all provide a similar function; they list the connections of an electronic circuit. This is important for a variety of fundamental tasks in electronics and PCB layout design. Your PCB netlist file is used graphically Read Article Using Terminations To Control Reflections In a previous two-part article, I discussed reflections , their origins and what they do to a signal using a typical unterminated 5V CMOS circuit as an example. As noted previously, this information applies to any logic family. This article will focus on how reflections can be controlled through the use of different terminations. Included in this discussion will be a description of the properties of those terminations and which work best in Read Article PCB Functional Testing and The Role of Manufacturer Collaboration Getting your PCB functional testing requirements correct is easiest when you collaborate with manufacturers during the design phase.

Read Article PCB Design for Radio-Over-Fiber Technology It’s possible that radio-over-fiber technology is one of the least discussed aspects of fiber telecom networks. However, it stands to be one of the many portions of telecom infrastructure for bringing broadband wireless access to remote areas. This approach is likely to play a major role for future 5G infrastructure in rural areas where a standard wireless backhaul is not possible or cost-prohibitive. Just like any other electronic system, radio Read Article How to Manage a Remote Team for Electronics Design Here’s how to manage a remote team for electronics design with powerful design, collaboration, and management tools.
