The microprocessor world seems to be going in ARM direction. And so seems to be microcontrollers. Cheap ARM based 32-bit micro-controllers are taking their place and trying to replace less powerful 8- and 16-bit micro-controllers. I wrote earlier that Arduino Goes ARM. It took quite bit of time for Arduino to take that step and →

The author of CNET’s The Audiophiliac blog recently asked, “Who wants perfectly accurate sound?” His answer? Most headphone and speaker buyers prefer less accurate sound reproduction. Consumer audio: Is accurate sound overrated? blog posting says this may be the case (although he doesn’t supply any real evidence to support this assertion). If so, so be →
PCBs without any substrate article tells that Kimio Kosaka is taking the concept of free-formed circuits to the next level with O’Baka Project No.7. Arduino Skeleton “0′baka Project” means a stupid project. This project is to make things which is not art and which is not usable. It’s a fully functioning Arduino board, without the →
In Internet there seems to be many plans for DIY logic analyzers: Open source logic analyzer OpenBench Logic Sniffer Openbench Logic Sniffer SUMP FPGA Based Logic Analyzer FLASH – PLAICE: Programmer, Logic Analyzer and In-Circuit Emulator Project A logic analyzer using the PC’s parallel port A logic analyzer using the PC’s parallel port MiniLA – →
The LED As We Know It Is 50 Years Old Today. In 1962, 50 years ago today, Nick Holonyak Jr. and his team at GE invented the Light Emitting Diode. While LED lights are almost everywhere today, their initial development was ripe with uncertainty and competitive research. A direct result of another groundbreaking technology of →
Logic analyzer is a very useful tool for embedded system debugging. In many embedded-system magazines and on Web sites you’ll see advertisements for instrument “boxes” or pods that connect to a PC through a USB port. These devices capture digital and analogue signals that a host PC displays in a standard scope or logic-analyzer format. →
