Power: When is an LDO More Efficient Than a Switching Power Converter?

When you have one voltage (5V from a USB connection for instance), and you need to power a component at a lesser voltage (3.3V for a microcontroller for instance), you have a choice to make: do you use a switching converter or a linear regulator to generate the lesser voltage? On...

Here is a selection of tools which I found most helpful for optimizing websites for mobile use. This is just a simple, short list of particularly effective resources, but there is plenty more detailed content available.

There have been interesting developments in the world of small FPGA's over the last five years. Tiny "chip scale" FPGAs under 4.5 mm x 4.5 mm containing a large number [6,000 (for Lattice Crosslink MD6000) - 8,000 (for the Intel/Altera MAX 10M08)] of LUTs have become available. This is equivalent to the largest Xilinx XC4000 series FPGA from the ye...

Dowel pins are useful for locating a part into a repeatable, fixed position. They are often used to align parts that need to be more precise than simply lining up screws, as screw holes generally are used for fastening, and not precise alignment. However, pinned joints are not as precise as kinematic couplings, which are used for more precision and...
