Plasma Arc Speakers: How They Work

In science fiction, plasma-based technology is often included because it is perceived as futuristic and exotic. Referring to plasma as exotic is understandable, but the technology behind its creation is less so. Since the invention of electric circuits, it has been possible to easily create and control plasma using high voltages. It is pretty common knowledge that high voltages ionize the air producing plasma arcs. What is not-so-common knowledge is the fact that these arcs of plasma can be used to play music.

Remotely Control FM Radio with a chipKIT uC32 and Basic I/O Shield

Recently, a user of our products posted a tutorial about using a chipKIT uC32 to remotely control an FM Radio. We always love to see our users creating cool projects and try to give space here not only to projects created by us at Digilent but also by you the user. This project does require the use of multiple components and could be a bit overwhelming to a beginner, but we encourage you to try it out if you so choose!

How to Create Light Paintings with WS2812 LEDs

A friend of mine came into town for Christmas and I wanted to do some sort of photography project with him. A few months ago, there were some pictures floating around the internet from Stephen Orlando, who took LEDs and attached them to a kayak paddle and kayaked around a lake, and through rapids. I wanted to do something similar. The first night wasn’t very organized. We went into the woods with just the LED strip, the chipKIT board (the uC32), and a battery.

ZYBO Smart Car

The ZYBO Smart Car was developed by Digilent China. It is one of the items in the Zrobot line, the educational kit solely developed by Digilent China. The smart car is powered by the Digilent ZYBO that features Xilinx Zynq technology. Users can control the robot from an Android phone using the Bluetooth interface within 20m. The OS is Linux. Users can develop the software and Linux driver using Xilinx Vivado.

A Listening Calculator

When working with microcontrollers, it’s pretty straightforward to have your system board “listen” for an input that you would give it and have it do some sort of action to show that it noticed your input, such as pressing a button to light up an LED. Listening to a set of inputs and then comparing them to a predetermined set, like in the Simon Says game, is a little more involved but definitely doable. But what if we did not compare to any internal values and the system board has no idea how many inputs we might provide?

Running 5+ Servos on a uC32…Can I Do It?

In the not too distant past, we made a couple of posts on Pmods that can help drive motors as well as a post on stepper motors. Today, we’re going to check out running multiple servo motors on a chipKIT board. Why would we want to do this? Well, aside from the nice feeling that comes from successfully doing some extreme multitasking, we’d also be able to run some super cool mechatronics projects, such as a robot arm!

Microcontroller Dice Roller — Made in the MakerSpace

If you’ve been keeping up with our blog, you’ve probably seen something about us setting up our very own MakerSpace here at Digilent. We’ve come a long way from a few cluttered cubicles to getting our MakerSpace up and running. We have just about everything you can think of to make any project imaginable: a 3D printer, a soldering station, breadboards, buttons, copious amounts of LEDs, and more! I thought up a just-for-fun project and wanted to test drive the MakerSpace to see what I could build.
