How to protect RS-232 serial connections

How to protect RS-232 serial connections article pointed me to a recent white paper from APC-Schneider Electric that explains specific power protection issues related to RS-232 cabling. The Protection of RS-232 Serial Connections document contends that the RS-232 port often represents the “Achilles heel” of computer installations which are otherwise well protected by UPS systems

3D printing is hot

3D Printing Flies High now. Articles on three-dimensional printers are popping up everywhere these days. And nowadays there are many 3D printer products. Some are small enough to fit in a briefcase and others are large enough to print houses. Everything you ever wanted to know about 3D printing article tells that 3D printing is

H-Bridge Motor Driver Module

H-bridge circuit is a very useful in electrical motor controlling. You can drive a DC motor easily at both directions with H-bridge, and if you add some PWM to driver circuit you can even control the motor speed on both directions. There are very many simple H-bridge circuit designs in Internet. Nowadays there are many

Very minimal Arduino-compatible circuit

I saw some days ago a pointer to The ultimate low-cost dev board. Or at least looks pretty close to it. The shrimp is a very, very minimal Arduino-compatible circuit meant to control all the pins on an ATMega328. The components only cost about £1.40 ($2.25 USD) when bought in volume, making it perfect for

Visualizing 100,000 Stars In Chrome

Google has rolled out a new web experiment for Chrome. 100,000 Stars: Google’s latest Chrome experiment taps NASA to visually explore the Milky Way. This one is a visualization of the locations of over 100,000 nearby stars (pulls data from astrometric databases and catalogs). Using Chrome’s WebGL, CSS3D, and Web Audio support, you can zoom

Open 7400 Logic Competition

The Open 7400 Logic Competition has brought awareness to open hardware and software, and fosters understanding of the building blocks of modern integrated circuits. What can you build with basic logic chips? 7400 Logic Competition winners are announced According to competition results page all the entries were amazing! There are quite a few of them.

Patent battles

I have been following news around patents lately. I have followed what happens on patent field because I am an inventor that has made some patents and being referenced on some other. The patent situation seem to be quite insane right now, especially on smartphone field. I can agree the comment Patent law is a
