Count your blessings.... Sure, it would be great to be challenged with technical problems that filled your day with lots of work. But can you take it upon yourself to proactively fill your day with engineering innovation? Many grizzled engineering veterans complain that we don't have enough...

You can make a simple soft-starter with a voltage-controlled switch that slowly charges an upstream R-C circuit. When the bus voltage builds up, short out the resistor. Then you should have enough energy ready before kicking the motor on. Alternatively, you can put the switch resistors into...

Funny, this was the topic of my masters thesis many moons ago. I had to do this over a ham radio link (FSK modem with P-CSMA and encryption using an X.25 protocol hosted on a TI DSP platform). What is your encryption method? Is your problem with modulation or encryption? Vince Socci...

Standard audio mixers will do this, if you have the right adapters. No need to build it if you can buy it cheaper. Back in the day when Radio Shack actually sold electronic gadgets, this would be easy. Now you might have to order it online. Vince Socci www.ontargettechnology.com

I am working on a hybrid electric vehicle application. The electrical system will put out some auxiliary power (30kW) to use for various loads. Most of the power will be used when the vehicle is stopped (not during vehicle propulsion) but some will be used on-the-fly. My question is ... Are...

Mathworks has great documentation online. There is an extensive set of self-study tutorials to teach you how to use the tool. Where you might struggle is learning how to simulate systems in your industry. That requires the school of hard knocks or a mentor with experience.
