World Wide Web turns 25 years old. World Wide Web turned 25 years today according to The browser’s resized future in a fragmented www world article. Wikipedia verifies that in March 1989 Tim Berners-Lee, a British computer scientist and former CERN employee, wrote a proposal for what would eventually become the World Wide Web. Twenty-five →
For something as ubiquitous as the internet today, it certainly isn’t easy to find where it all started. You might know History of Internet quite well in technical details, but what about the locations? Gizmodo article This Is The Room Where The Internet Was Born shows where the first ARPANET node was installed, where communications →
Few days ago I wrote about SCADA for Arduino that allowed to build a nice computer user interface for controlling Arduino. This post is a continuation to that. In the earlier posting I got the LED on Arduino board to be controlled on/foo with SCADA software. Now I connected a relay module to this output →
In recent years, continued technological innovation in digital video has pushed the boundaries of “high-end” video resolution from 1080p (2K resolution) to 4K. 4K video has considerably higher number of pixels than HDTV has: 4K approximately four times the number of pixels compared to 1080p display. Today 4K the highest resolution format available for consumers. →
Scientists explain their processes with a little too much honesty and Scientists explain their processes with a little too much honesty [17 pictures] articles show a series of pictures that might find funny. Back in January, scientists started making “secret” confessions on Twitter and some some kind soul combined a few of these Tweets with →
Acimut Monitoriza for ARDUINO is an interesting project that combines that combines free Scada software with Arduino hardware platform. Acimut Scada Monitoriza is a SCADA application that lets you control any process. It is designed for control and monitoring of production plants, and costs some money. Acimut Monitoriza for ARDUINO project offers Scada Monitoriza software →
I have written about Arduino boards a lot, but there are also other small interesting quite similar development board recommended for me to check out. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port and →
Why modern high tech electronics fail? Very often the reason for that is electrolytic capacitor failure. Bad electrolytic capacitors on my PC again. The PC stated acting bad. It kept resetting my itself and quickly failed to boot. So I had to start fault-finding. In this kind of cases, the problems could be bad contact →
I needed to do some AC current measuring with Arduino, more accurately than with special AC current sensor I tested earlier. To do that measuring I bought Meeeno ACS712 Current Measuring Sensor Brick Module Board for Arduino. This is a picture of that module from dx.com: This module is pretty easy and safe way →
Few days ago Hackaday reported that after a failed Indiegogo crowdfunding campaign, MobilECG has gone open source. MobilECG is a medical grade 12 lead electrocardiograph that connects to USB port. It is designed to meet all the relevant medical standards (ISO 60601-1, etc.). It was designed to work with PCs, notebooks, and Android tablets. Records →
