“I generally get project ideas before looking for components. For the whistled, things were the other way around.
A few months ago, when finding a new 32pins Cortex M4 , I got plenty of ideas and the whistled was one of them.
As mentioned in the video, this tiny Kinetis K10 can perform around 80 [q15 2048 points] FFTs per second and still give me time to run my own algos.”

“My main objective in this project is to work on core computer vision algorithms which enable the blimp to navigate through its envirnment autonomously. The camera is the most important sensor – it provides continuous live image capture for onboard ‘optical flow’ calculations, a very effective technique for obstacle detection and velocity measurement.”

“This project is my first attempt to make a biped walker — and using only three servos. 3S-1 (for Three-Servo walker One) is modelled loosely after the VStone RB300, as seen in their gallery and discussed in this RoboSavvy thread.”

“Here you will find some info and see some pictures of the second RGB laser projector I built….also see how others have modified their Laser Projectors.”

“Cardbot is a functional robot made from laser-cut corrugated cardboard. It is battery powered and wirelessly controlled over 802.15.4 (Zigbee.)….I had the idea that I could build a kit for a robotic base, itself a press-fit assembly kit, that could also serve as a mobile base for other press-fit constructions.”

“The goal of our project is to create a VGA video adapter. This ‘homemade video card’ should be able to connect to any monitor that subscribes to VGA standards with a standard connector and display the desired material reliably. The challenges involved here stem from adapting a general use microprocessor that we are familiar with to a specific task…”

Time for another new lesson on PyroEDU’s current course: Introduction To Digital Electronics course and it’s called Clocks and Oscillators. Here is what this week’s lesson is all about:

The heart and soul of any digital system is the main clock signal. It drives every single flip-flop that is inside of the system and therefore it is the most important signal. In this lesson we will learn how to use a 555 timer as a clock signal generator and we will also look at using crystal oscillators to generate clock signals.

“This device acts as interface between your microcontroller project and a GSM phone. It handles all modem data communication between the GSM phone and your micro-project. The best thing is that it decodes PDU into TEXT on the fly!”

“I am trying to interface an LCD panel from a vintage 486 Compaq Contura 420cx to the VGA port at 640×480 resolution with 3 bits of color (one bit per color — RGB) for the purpose of displaying data from my upcoming ENSURE-2 near-space project.”

“Rarely a month goes by without an article in SERVO Magazine describing the communications needed to control an analog R/C servo, so I will keep the review short. There are no official standards on R/C servos, so many aspects of their operation vary from manufacturer to manufacturer, or even for different product lines from the same manufacturer.”
