5 Great Uses of the Spread Operator in a React App

React has quickly become one of DMC’s favorite tools for web frontend development due to it’s component-based structure and growing adoption. However, between the JSX syntax, component lifecycle, and state management, learning to use React effectively sometimes feels like learning a language in and of itself. Javascript’s spread operator sees a lot of use in DMC’s React applications due to its concision and versatility. Here are 5 of our favorite uses of the spread ope...

8 Readability Tips to Try on Your Next HMI Project

Why do we code PLCs, design HMIs, create complex SCADA networks? The short answer is - so that somebody can use them to get a job done. For an HMI to be useable, it must be readable. Readability isn't just a matter of word choice. Technical choices like text alignment, line width, or font size can make or break readability. Here are eight tips for ensuring readability in your HMIs:  1. Left-align Text Likewise, justifying text creates awkward g...

Employees Lead Company Improvements During FedEx Day 2018

DMC recently took a break from day-to-day tasks to participate in one of our favorite company traditions, FedEx Day. Routine work on hold, our offices still brimmed with life and projects while everyone worked on whatever they wanted.  FedEx Day is always an opportunity for fun, learning, and collaboration, with only two catches: the project must in some way help to improve the company, and it must be deliverable by the end of the day. This year, our employees took on everything ...

Frame Accurate Video Scrubbing in the Client

There are a variety of desktop applications that allow users to seamlessly scrub back and forth through a video to determine the exact frame in which some action should take place or where the placement of a tag should go. Some popular applications include Final Cut Pro and Adobe Premiere Pro. This sort of smooth functionality is difficult to attain on a website due to the limited resources of a browser client in comparison with a desktop environment.  In this post, I will walk through h...

Nucleo UART Tutorial Mbed-Style

Introduction ARM touts its mbed platform as an all-in-one solution to the Internet of Things. Today, we’re going to focus on one of its great benefits: “vendor-layer” abstraction. In other words, with mbed, you don’t have to write code for a specific target. Mbed will compile it for the target you want, whether it’s an EFM32 or an STM32. At DMC, we work with all kinds of different platforms for all kinds of different projects. Being able to borrow and port ...

Turning an Arduino into a Modbus Device
Eric Baggen

Turning an Arduino into a Modbus Device

A situation arises where you have a system that includes a PLC, an HMI, and some peripheral devices. The HMI displays some information to a user and allows for some basic control and the PLC manages data collection and communication through an RS485 network using a Modbus RTU protocol. Easy, right? Many PLCs already support RS485 and Modbus communication and only require a few functions blocks. There is a twist, however. The devices with which the PLC is communicating a...

Setting Up Docker for WordPress Development

Way back when in 2014, I wrote a blog about setting up WordPress on IIS. At that time, Docker was only a year old and I hadn't even heard of it. It's now 2017 and things are different. Docker has matured and has gained enormous popularity for making developers' lives easier. One of Docker's uses we'll examine today is using Docker for development, particularly web development in WordPress. First, let's have a little Q&A session and then we'll jump r...

Low Cost Function Generator Amplifier DIY
Tim Jager

Low Cost Function Generator Amplifier DIY

Introduction A majority of function generators are only capable of driving a couple hundred milliamps, which is fine for most applications. If you want more output current, you can shell out $400 dollars for a professional signal generator amplifier, or you can do what I did and hack one together for under $40. A signal generator is an indispensable tool for developing and testing electronic designs. You may find yourself wishing yours could output more current. You could test your po...

Boston FedEx Day Produces Smart Bike Lights

It's not fair.  Your car shows brake lights when it brakes. Some cool cars turn their lights on when you approach your car at night. Some really cool cars change the intensity of brake lights when they brake hard.  My bike has a red light that turns on when you press a button.  NOT FAIR.  For my FedEx Day project (a day where our company lets us make anything for 'next day delivery'), I brought my bike into the future with the help of a coworker and a ...

Using IoT, a Particle Internet Button, and Slack to Feed a Fish

"Stevie is a fish. Stevie has no motors. Stevie prefers that you don’t tap on the tank. Stevie doesn’t know what Wi-Fi is. This is a picture of a computer. It’s not a fish. Stevie is a fish! I bet Stevie wishes he had hands so he could play with tablets." This description is printed on a sign that sits next to Stevie’s tank. Who is Stevie, you might ask? Stevie is DMC Boston’s office fish, and he is a valued member of the team. Like us, he ...
