Phidget Smoker Project #2: Dual Element Bradley Smoker (SmokerPI)

This project is a continuation from the Phidget Smoker Project #1. We replaced the PC with a Raspberry PI, and built an enclosure for the hardware. We also installed a second burner in the Bradley smoker to help it keep up with the strenous Phidget smoking demands.

Phidget Smoker Project #1: Control a Bradley Digital Smoker using Phidgets

This project demonstrates the use of the Phidget JavaScript libraries for node.js to control a Bradley digital smoker. The smoker was modified with an external thermocouple attached to a Phidget 1051_2, and the power to the heating element was interrupted with a Phidget 1014_2 relay. A Linux PC running the Phidget network server and node.js was connected to the 1014 and 1051, and a custom node.js program controlled the smokers temperature.

Encoder Velocity: A Common Miscalculation

When working with Phidget Encoders, a tempting method to calculate their velocity is to simply divide the number of pulses (or edges) by the elapsed time given by an event. However, problems arise with this method when the encoder starts and stops, or moves slowly enough that it’s hard to tell the difference.

Specialized Sensor Series #3 – RFID

At Phidgets, we try to make a wide variety of sensors available to our customers. If we can’t make the sensor ourselves, we try to find a manufacturer so we can sell a third-party sensor to fill the gap. However, some types of sensors have such a niche market that it doesn’t make sense to sell them at a (relatively) small store like Phidgets. The purpose of this series of blog posts is to highlight a specific class of unique sensors and walk through what options are out there and which ones will work with your Phidgets devices.

How the RoboDose uses Phidgets to Safely Deliver Medication

Earlier this year, a group of high school students from Walker Career Center in Indianapolis competed in Phoenix Contact's Nanoline contest. They call themselves the Nano Consultants, and their vision was to build a device that would dispense proper dosages of medications to patients prone to forgetting their medication. They call it the RoboDose.

How to Give Your Phidgets a Custom Label

At first glance, the device label property looks simple and maybe even dismissible. If you noticed it at all, you may have even wondered why it’s there, but be assured, there are some really neat things that you can do with it. You can hold device-specific flags, differentiate between multiple Phidgets by giving them meaningful names, or give them custom serial numbers.

How to Log to USB Flash Drives from the SBC

There are quite a few users making their Phidget SBCs do data acquisition, and perhaps this is the plan you have for yours. Depending on how much data you want to collect, and because of limited space on the SBC itself, you’ll probably end up using something like a USB drive to store your data logs. It’s really easy to set up, but there are a couple gotchas that you might want to consider before writing your program, so let’s go over them and talk about the basics of logging to the USB flash drive from the SBC.

How Phidgets Make Museums More Interesting

While many people prototype their designs with Phidgets, there are a lot of people making one-time installations to work with Phidgets on a long-term basis. These people make museum exhibits, as well as interactive art installations (like Eos Lightmedia). Phidgets help the creation of exhibits that move people from being passive observers to engaged participants in learning.

How to Set Up Multiple RFID Readers in Close Range

Using multiple radio-frequency identification (RFID) readers in a relatively confined space can be a tricky proposition. We tell our customers that if they want to have multiple readers in their application that they should space them at least 1 meter apart. That is quite a significant distance, and in some cases, it isn’t practical.

How to Run Sensor Cables Through USB Cables

You might have noticed that sensor cables don’t come in a convenient round shape, which you sometimes need. A relatively easy solution is to grab a length of USB cable and solder the sensor cable wires onto the USB wires, and here are some easy instructions to get it working:

How to Make a Phidgets-powered Night Light

Use Phidgets to control a night light. In this project a pressure sensitive rug is attached to the SBC digital inputs to turn the LED light on and off. When the light is triggered, the SBC polls a temperature sensor and the lights takes on a colour based on the temperature outside. As the temperature changes, so does the colour displayed by the light. An IR distance sensor allows you to simply reach over and turn the light on (to white light) or off, so you don’t have to step on the rug all the time for light.

How To Avoid Grounding a Thermocouple

If you’ve never seen a thermocouple before, you might think it’s just a cable with some wires inside. Well, it is, in way, but it’s really a tool for measuring extreme temperatures far outside the range of many other types of temperature sensors. A thermocouple has two different conductors that produce a voltage. The voltage is proportional to the temperature difference between either end of the pair of conductor

Exploring the Many Methods of Object Detection

There are a lot of different types of sensors out there that can be used to detect the presence of an object or obstacle. Figuring out which one is right for your application can be a bit difficult, and is highly dependent on the requirements of the application. Sensors vary in their method of detection, and each has distinct strengths and weaknesses:

How To Calibrate Phidgets Sensors

When using certain sensors and devices, you'll need to do some calibration to ensure accurate measurements. For some sensors, you'll probably want to do your own calibration but some Phidgets sensors will have calibration values written on the back of the board (like the light sensors)

Steppers with Encoders: When Open-loop Control Is Not Enough

With the increasing popularity of DIY projects such as quadcopters, CNC tables and 3D printers, many people are faced with the decision of which type of motor to use in their project. For applications that require precise control of the position of the motor, the common choices are DC motors with encoders, servo motors, and stepper motors.

Fields of grass alight around your ankles, towering trees sing above your head and benches respond to your pressure, colouring a digital sky complete with a custom soundtrack.
