This past week saw the release of PixelMaestro 2.0, and with it, a bunch of fixes to device communication and control. You can now plug in any Arduino-compatible board with an attached LED strip or matrix and start controlling it in a matter of minutes. Not only can you send commands to it in real-time, but you can upload complete configurations and store them in EEPROM for long-term storage, even across reboots. This was possible in previous versions of PixelMaestro, but now it’s even easier.
This post demonstrates some of PixelMaestro’s new device integration features and example sketches.
Google’s Digital Wellbeing app found its way onto my phone yesterday, and it’s an interesting new app. Unlike most apps, which fight to hold your attention as long as they can, Wellbeing is all about getting you off of your phone. For a company that amassed its fortune on clicks and views, this seems counter-intuitive. What exactly does Wellbeing offer, and can it actually help you spend less time on your phone?
Most of us experience at least one major shift in how we perceive the world. Whether it results from a traumatic event, or from the natural aging process, at some point we find that our old habits no longer serve our current needs. For me, one of these shifts happened earlier this year.
After taking some time to reflect on the experience, I set about summarizing my thoughts into a set of simple guidelines. These guidelines are meant as a motivational tool to keep myself focused on the things that are the most important to me. I called these guidelines the Three Cs.
About a year ago, I started looking into ways to cross-compile Windows applications from within Linux. This brought me to a cool project called MXE (short for M Cross Environment). With MXE, you can use your Linux machine to generate Windows binaries without having to install any virtual machines or compatibility layers. In this post, I’ll walk you through the process of setting up MXE and turning your source code into a Windows program.
While working on the next release of PixelMaestro, I came across a problem of storing long-term data on an Arduino. I have a system in place where configuration changes are sent to an Arduino over USB as byte arrays, and as the Arduino reads the array it applies the changes. The problem is those changes disappear as soon as you restart the device. How, then, does one store persistent data without having to add an SD card or extra memory? Enter EEPROM.
In an earlier post, I explained how I used version control software to manage my creative writing documents. Since then, I’ve developed a setup that’s more transparent, easier to work with, and requires less command-line wizardry.
In an earlier post, I explored the idea of productivity gamification and how it can help increase your motivation. I’ve been testing this over the past few weeks by using an Android app called LifeRPG to track my habits, tasks, and important milestones I wanted to reach. In this post, I’ll go into detail about my LifeRPG setup and how it’s helped me stay focused in my everyday life.
Each day begins with a list of tasks I want to accomplish. Whether it’s short-term (writing a blog post) or long-term (working on a programming project), completing each task helps me feel more successful. But sometimes motivating myself can be difficult, and on some days even the simplest tasks can seem insurmountable. In this post, I’ll discuss a strategy I recently found that actually makes everyday tasks seem fun!
Today marks the release of PixelMaestro version 0.8! This release introduces several big changes including new features and better performance. To learn more, keep reading or visit the PixelMaestro GitHub page.
On today’s episode of “Adventures in C++”: sending commands between two Arduinos running the same software. Not just data, but also instructions on how to process and execute that data. Even more, these commands have to be small enough for each Arduino to package, send, receive, unpack, and execute in less than 1/10th of a second.
