“One of the great aspects of the logic is the speed and the full control of what happens at every single clock cycle….In this short post I will walk thru our current test setup with an FPGA, the Spartan 3E, controlling a 18-bit 7″ 800×480 TFT display.”

“This amazing looking device is a quadcopter that was designed by me and my team at the University of Victoria….The purpose of the project was to create a DIY quadcopter for under $200 and push the limits of what the 3D printer in our laboratory can do.”

“The first decision you have to make is which Arduino compatible microcontroller you are going to base your circuit around. This will depend on the number of input/output pins you need as well as the size of the compiled sketch you intend to use. Given that I’m prototyping my ideas using an Arduino UNO, I decided to stick with the ATmega328P-PU chip the UNO is based around.”

“In this post I’m going to first alter a robot arm I had built previously from a beginners kit so that it can be controlled from Arduino. Then I’m going to write a series of posts on different ways to control the robot arm using Processing and other things.”

“One of the first projects I published online a couple of years ago was about how to put together in a prototype board a simple circuit to interface a 10BaseT ethernet controller with a Microchip PIC18 microcontroller running the TCP/IP stack developed by Microchip. I called this project the PIC10T.”

This week we’re rolling out a new less for our Introduction To Digital Electronics course and it’s called Design An SR Latch. Here is what this week’s lesson is all about:

The next step into the digital work is to create stable logic elements. The first such element is called a latch and it can be built using simple logic gates. In this lesson we will explore how to build a latch using NOR logic gates and NAND logic gates. In addition, we will take a look at what timing diagrams are and how to use them.

“Finally I have found some time over the past week-end to enhance my Zumo robot. After I had my line following robot based on the Pololu Zumo chassis and the FRDM-KL25Z, I thought it should be easy and logical to solve a maze. Logical: yes. Easy: not that much. In fact it took me longer than expected. As always, there are a lot of tiny and important problems to solve.”

“I found a nice article on using the twitter search API in python and used it as a base for my script. Here’s what it does: first, it searches for the string ‘my favorite color’ and in practice finds around .1-5 tweets a minute…the script simply cleans up the tweet, removes any strange character like ‘#’ and compares every word of the tweet with my lookup table. The first color string in the tweet wins.”

“This small PCB, which I named Multiuse tiny1 was originally designed to convert NES/SNES controllers to USB. Since there is not a lot of space availabe inside an SNES controller, I designed the PCB to be as small as necessary. The PCB has improved since the beginning, thanks to the many other uses I found for this PCB.”
