WS2812 addressable LEDs test

RGB LEDs are awesome – especially the new, fancy ones with the WS2812 RGB LED driver. These LEDs can be individually controlled to display red, green, and blue, but interfacing them with a microcontroller or computer. To test controlling WS2812 RGB LEDs I bought a cheap addressable LED strip. An addressable RGB LED strip is

Duktape

Using JavaScript is a new approach for embedded development, especially with node.js platform. But there are also other interesting JavaScript platforms worth to check out. I read about Finnish developed the open source “duct tape” and thought to check that out: Duktape is an embeddable Javascript engine, with a focus on portability and compact footprint.

New Finnish high tech magazine with articles written my me

Finland has received a new technology trade magazine focusing on developing new technology: Uusi Teknologia (=new technology).  Uusi Teknologia magazine’s first issue devoted to IoT solutions, industrial, internet security and future 5G mobile solutions as well as intelligent interactive textiles. Also included are high-end oscilloscopes and a new ways to program embedded systems. The magazine

New approaches for embedded development

The idea for this posting started when I read New approaches to dominate in embedded development article. Then I found some ther related articles and here is the result: long article. Embedded devices, or embedded systems, are specialized computer systems that constitute components of larger electromechanical systems with which they interface. The advent of low-cost

VGA signal generation hacks

This is continuation to Interesting VGA hacks hacks posting. Interesting VGA hacks hacks was concentrated on using VGA card for nontraditional uses, this posting on the other hand concentrates on generating VGA signals with other hardware than VGA graphics card. It seems that modern microcontrollers are well suited to display information on analog VGA monitors:
