Peeking inside an HDD

I’ve expressed no shortage of admiration in past writeups (stretching back…oh…a quarter century or so…) for the flash memory industry’s incremental cost, capacity, performance and reliability accomplishments over the years. I suppose I’m (more than) a bit biased because my post-college (not including during-college-co-op) engineering “origin story” involves eight years with Intel as an applications … Read more

One man’s trash

I took a consulting job with a major semiconductor-equipment-manufacturing company. There, I built various test fixtures using surplus VMEbus-card cages that the company had in the warehouse. It was great to be able to get almost the same card cage that the company was shipping in the current product. One day, I found myself requesting … Read more

The transmitter compliance test application works with Agilent Infiniium oscilloscopes, while the receiver compliance test … Read more

The many faces of jitter

In high-speed data communications, jitter can be a surprisingly abstract concept. Experts spend years working to develop an intuitive understanding of its behavior. For novices, the sheer amount of information can be intimidating. Whenever I need to explain jitter issues to engineers new to the field, I use Figure 1 to convey the relationships between … Read more

Not Your Father’s Calculator

Most technicians and engineers have a special calculator that they call their favorite. This calculator may be the one that got them through algebra and upper level engineering classes, or the one associated with a particular memorable portion of their career. In some cases, a favorite calculator is the only calculator a technician or engineer … Read more

Seiko shrinks footprint of POS thermal printer

The latest entry into Seiko’s Qaliber line of thermal receipt printers, the Qaliber Lite RP-D10 offers one of the smallest footprints in its class for space-constrained point-of-sale environments, squeezing into a 5.08-in. cube that permits both front and top access control. Despite its small size, the RP-D10 delivers print speeds of almost 8 in. per … Read more

Combo sensors fit wearable devices

Two combination accelerometer-gyro sensors, the KXG07 and KXG08 from Kionix, a subsidiary of Rohm, provide six axes of motion sensing. Both devices feature a configurable low-power architecture and a large 4096-byte FIFO buffer with timestamps for use in gaming systems, smart phones, and wearable devices. Unlike conventional sensor signal-detection methods based on amplitude detection, the … Read more
