Why Don’t They Just…

The Quest for Truth in Engineering

by Kevin Morris

“Why don’t they just put solar cells on top of cars and power them that way?”

His tone implied that the engineers designing cars were just idiots, and he was sure he could do better - with just this one idea. I was going to answer with some helpful information about the amount of energy required to operate an automobile, the amount of energy collected by even idealized solar cells, and the amount of area available on top of a typical vehicle. I didn’t get the chance.

His friend interrupted, “Well that’s just the government shutting them down. The oil companies have the government in their pocket, and they’re not about to let anyone develop technology like that. It’s the same with that 200 MPG carburetor that guy in Florida invented…”

Now, I was more hesitant to speak. I wanted to explain that modern, sensor-driven, computer-controlled fuel injection systems did a much better job achieving near-ideal fuel-air mixtures than any carburetor could ever hope to accomplish. I didn’t get the chance.  Read More

@TotallyLost, I agree completely. All of us should challenge misinformation when we see it being propagated, and we should work very hard to be sure that what we publish or broadcast is correct.

I feel that we in the press have an additional responsib…

High Speed Data Acquisition and Software Defined Radio Made Simple

Building a hybrid computing platform from scratch is a huge and complicated project. Luckily, somebody has already done that work for you. In this episode of Chalk TalkHD Amelia chats with Justin Braun (4DSP) about how you can use pre-designed platforms to dramatically simplify these complex computing and data acquisition problems.

Integrated Design Environment for FPGA

Do you find that FPGA design flows can get a bit confusing and difficult to manage? What we really need is an integrated design environment that will help us keep our design activities organized. In this episode of Chalk TalkHD Amelia chats with Satyam Jani from Aldec about integrated design environments (IDEs) for FPGA design, why FPGA designers need a vendor-independent IDE, and how an FPGA-centric IDE can help us get through our design flow quite a bit more easily.

Developing Clean Efficient Power with LLC Resonant Converters with Infineon

Ready to get your black belt in DC power conversion? In this episode of Chalk Talk, Amelia Dalton chats with Sam Abdel-Rahman of Infineon about how to make a versatile, high-efficiency, LLC resonant mode power converter. So, buckle up, hit play, and get your DC on!

Integrated Power and System Management

In this episode of Chalk TalkHD Amelia chats with Shyam Chandra of Lattice Semiconductor about an integrated approach to system and power management that will lighten your design load, improve your overall system design, and probably lower your total cost at the same time.

Graphics Rendering and Video Processing with Altera SoC and Helio View Dev Kit

For performance-critical applications like graphics and video rendering, the partitioning between software and hardware can be a pivotal decision. Today, exciting new devices allow us to make and evaluate those tradeoffs more easily than ever. In this episode of Chalk Talk, Amelia Dalton talks to Troy Jones (Macnica Americas) and Todd Koelling (Altera) about creating video and graphics applications using the Helio View development board with Altera SoC FPGAs.

Building a New Type of IP Factory

Reliable IP blocks are essential to the success of most modern SoC and custom IC designs. But finding a reliable, reputable source of verified IP can be challenging. In this episode of Chalk Talk, Amelia Dalton talks to Kevin Yee (Cadence Design Systems) about Cadence's substantial IP offerings

DO-254 Requirements Traceability with Spec-TRACER

In this episode of Chalk TalkHD Amelia chats with Louie de Luna about Aldec's new Spec-TRACER tool and how Spec-TRACER helps you navigate your way through your design flow - from beginning to end, from requirements to verification.
