Etching sketches with a Netduino Go
Netduino Go is designed for much more than toy projects, but one has to recognize that toy projects are fun and also great learning experiences. Today, I want to take you through the process of reproducing the behavior of a famous toy that you will surely recognize. That toy, that has helped many of us realize what poor motor skills we possess, has two knobs that control the horizontal and vertical coordinates of a pen that draws into the dust on the back of a simple screen. It’s a great mechanical device that is part of western culture. -
Electronics for developers with Netduino Go
Wouldn’t it be great if you could build your own stuff? Microcontrollers let you do that, but they usually require dealing with a lot of complexity and unknowns. If you’re a software developer, chances are you don’t really know how to use a capacitor, or how a transistor works, even though it is at the heart of all computers. -
Building a simple Fritzing component
This is me shaving a yak. Shaving the yak, if you don't know, is what you do when a seemingly simple task necessitates many recursive and unforeseen sub-tasks in order to be carried out. -
Authoring SVG with a text editor
SVG definitely is an increasingly interesting skill, especially as it's making its way into HTML 5 as an officially allowed grammar inside of HTML documents. Most SVG is authored through some kind of tool, and it's absolutely the way to go for artistic drawings. I used Inkscape (open source) and Expression Design in the past for that (I can't afford Illustrator), and I've been happy with the results (to your right and left).

Driving a LED matrix from a Netduino one more time: The Right Way
In previous posts, we've seen two ways one can drive a small LED matrix from a Netduino. -
Mandatory look back at 2010
Yeah, it's one of those posts, sorry. -
Displaying an image on a LED matrix with a Netduino
In the previous post, we’ve been flipping bits manually on three ports of the Netduino to simulate the data, clock and latch pins that a shift register expected. We did all that in order to control one line of a LED matrix and create a simple Knight Rider effect. -
Doh! Use the right constants when you talk to a Netduino
When programming a Netduino microcontroller, you are going to use constants from the SecretLabs.NETMF.Hardware.Netduino namespace. In particular, there are constants defined for each of the microcontroller’s output and input ports, enabling you to write for example: var button = new InputPort(
Pins.ONBOARD_SW1,
false,
Port.ResistorMode.Disabled); -
Improving the Netduino Knight Rider effect with a shift register
In my last Netduino post, I showed how to create a simple Knight Rider effect. One of the problems of that implementation was that we were occupying one digital port of the Netduino for each light in the ramp. It’s fine for that simple effect, but in future posts we’ll look at controlling our whole 8x8 LED matrix, which has 16 pins whereas the Netduino has only 14 digital ports. -
More Netduino fun
Last time, we ran a very simple program on the Netduino. This time around, we’ll actually connect some real hardware to that microcontroller and blink some lights! You know what? Let’s go crazy! Let’s go for Knight Rider lights! Woohoo!
