Nuts and Volts has published the article “Working with I2C Sensor Devices” in the July 2017 issue. It walks you through how to interface with an I2C device using a single board computer. Be sure to visit your local bookstore and pick up a copy while they’re available!
In a continuing effort to usher their spa into the 21st century and stay top of mind with customers, Bozeman Hot Springs set out to provide real-time pool temperature data for their customers. They found an off-the-shelf solution with Technologic Systems which could integrate with their existing commercial automation controllers and serve temperature data over a REST API.

This practical guide gives us an opportunity to take a relaxed approach to getting started with the TS-7553-V2 single board computer. We’re going to take a look at how to make our first connections, and setup the network. These are usually the first things we do before starting development. In the grand scheme of things, this is just a friendlier extrapolation from the official TS-7553-V2 manual, so be sure to keep it handy for more advanced topics and specific details. The only assumption being made is that you’ve purchased the TS-7553-V2 with a development kit, including the pre-programmed microSD card and enclosure with 128×64 px LCD and 4 button keypad. Right then, let’s get started!

This is a comprehensive and easy to read example C code designed to work alone or included as a library for dealing with general purpose I/O via the sysfs interface in Linux. It can easily be applied to any computer which utilizes the GPIO sysfs interface (both pro and maker boards). Getting started is a breeze. You just need to decide if you’re going to use it as a library, including it into your existing code, or as a stand-alone utility. We’ll talk about both in this article, but first and foremost, here’s the source code we’ll be working with:

Blistery cold weather is starting to sink in, which ought to ignite an instinctual desire to get your house in order and monitor it so the water pipes don’t freeze and burst. So, we’ll take a timely look at a project setting up some temperature probes in various areas, reading them, and reporting in a custom dashboard. A true home automation expert would take things further by setting up relays to turn on heat tape or even maybe some actuators to control water flow. Maybe next year, but for now, we just want to be able to monitor important areas of our home (in this case a cabin in Montana) and understand temperature patterns over time for better planning. As with most projects, there is more than one solution, especially if it depends on what you have on hand. At the time, the list of things in hand were as follows:

Let’s take a quick look at what it takes to read from the ADC inputs of a i.MX28 based embedded system using example C code provided by Technologic Systems. Now, while this can be generically applied to many i.MX28 based embedded systems, we’ll be working with a TS-7680. Right, let’s get started!

This practical guide gives us an opportunity to take a relaxed approach to getting started with the TS-7600 single board computer paired with the TS-ENC750 enclosure with TS-752 baseboard. We’re going to take a look at how to make our first connections, talk about the Linux environment, and setup the network. These are usually the first things we do before starting development. In the grand scheme of things, this is just a friendlier extrapolation from the official TS-7600 manual, so be sure to keep it handy for more advanced topics and specific details. The only assumption being made is that you’ve purchased the TS-7600 with a development kit, including the pre-programmed microSD card and TS-ENC750 and TS-752 baseboard. Right then, let’s get started!

When washing electronic boards, a common concern among technicians is the purity of their water. Rightfully so because technicians don’t want filthy trace deposits left under and around sensitive components. Some might ask, “If water is bad for electronics, why wash them in the first place?” Washing boards is a common process in the electronics industry because when a board is manufactured or reworked, there is a substance called flux that needs to be removed or it will cause corrosion and longevity issues. Water is a readily available and an effective solution for removing flux. However, technicians need to choose the water carefully.
There are several different levels of water purity. Starting with the least pure option, typical tap water can be used for washing boards. The next quality improvement is using carbon filtered water which marginally helps with the contaminants in the tap water. A quality level above that is Deionized water (DI water) which is commonly used in the board washing process at high quality electronics facilities. Using DI water for the board washing process is optimal due to the absence of contaminants in the water. Because DI water is the purest form of water, electronics manufacturers focused on quality use this as a standard for board washing.

In a joint press release between partners Canonical and Technologic Systems, the pairing of Ubuntu Core and TS-4900 was officially announced.
We couldn’t be more excited!
We feel that Ubuntu Core is going to make a big splash in the IoT world for its security, ease of management, and flexibility. Combine that with our rock-solid, industrial TS-4900 and you have yourself a reliable, production-ready IoT device.
We’re very honored to be featured in the Ubuntu booth at the Mobile World Congress in 2017. For more information, please take a look at the press release, Bringing Ubuntu Core to the i.MX6 Based TS-4900. If that isn’t enough to quench your thirst, take a look at our Ubuntu Core Powered Embedded Systems page.
