Open Source Hardware Companies

Selling products whose design anyone can access, edit, or use on their own is pretty crazy. It’s also good business according to 13 Open Source Hardware Companies Making $1 Million or More (video) article. The article mentions thirteen companies with million dollar revenues from open source hardware (OSHW).Companies providing OSHW allow all designs of the

Cooling Fan Tachometer standards

Internet is usually a goldmine of all technical information, but there’s not much on the internet about the rpm rotation sensor and it’s specification. CPU Cooling Fan Tachometer standards tries to fill this gap. It page describes a little about the tachometer or rpm rotation sensor and it’s electronics. CPU fan pinout page gives the

Arduino programming

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. So very interesting stuff.. The microcontroller on the board is programmed using the Arduino programming language and the Arduino development environment. Arduino programming environment is lean

Car electronics security

Modern automobiles are no longer mere mechanical devices; they are pervasively monitored and controlled by dozens of digital computers coordinated via internal vehicular networks. Experimental Security Analysis of a Modern Automobile report experimentally evaluates these issues on a modern automobile and demonstrate the fragility of the underlying system structure. The paper demonstrates that an attacker

RAM was born

May 11, 1951: RAM Is Born article tells Jay Forrester files a patent application for the matrix core memory that day. A team at Massachusetts Institute of Technology led Jay Forrester developed a three-dimensional magnetic structure code-named Project Whirlwind. In short, magnetic core memory was the first random access memory that was practical, reliable and

ARM and Flash vs HTML5

ARM dominates the mobile phone chip design market now and has done that for some time. Since 2008 ARM has been trying to get into the subnotebook market as well with Linux-based, ARM-powered “smartbooks” that would provide an instant-on, longer-life alternative to x86-based Netbooks. Smartbooks have been delayed by Flash issues, says ARM. There has
