Screws Mess With Filter Design
Sherlock Ohms 4/18/2013 3 comments The filter had more rejection at the low end than at the high end since the equivalent capacitance coupling did not provide a transmission at high frequencies.
The Least-Obvious Signals Sometimes Bite You
Sherlock Ohms 4/15/2013 4 comments When is a digital circuit not a digital circuit? When somebody forgot that ultimately everything is an analog circuit, and things like L, R, and C combine in the most insidious ways to derail a design.
Car Radio Fires Up Check Engine Light
Sherlock Ohms 4/12/2013 19 comments Apparently the 2003 Saturn Vue has some interconnections between sensors that depend upon the integrity of the radio ground strap for proper operation of the engine and transmission control computers.
Antenna Tower 4 Has No Base Current
Sherlock Ohms 3/22/2013 19 comments Engineering problems in the broadcast field can range from defective components, operator errors, snakes, or a combination of factors. Sometimes you need to call Sherlock in to solve the case.
Brake Lights Were on the Blink
Sherlock Ohms 1/4/2013 24 comments An unsuspecting driver was startled by another driver's horn, after the brake lights on his vehicle did not illuminate before he turned. A $20 switch solved the problem.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
