Two bytes walk into a bar. The first byte turns to the second and says "I think I may have a parity error." The second byte turns to the first and says "yeah, you look a bit off."   Joe Paris
Previous Cool Reads Newsletters

Hey Cool Readers,

We now have a NEW new newsletter directory page. (Different from last week.) You can find any of the past articles there, link directly to the newsletters themselves, or just bounce around reading all the cool stuff. There's a mini directory in the right sidebar that you can access within any article and link to the complete directory page (or just click here to see it now).

Also, don't forget all the posted parts of any article series have been grouped together in the "Series" tab located in the same right sidebar. (It magically appears when you access any article that's part of that series.)

It's also worth mentioning again that we have a share button at the bottom of the articles, so you can show all your Facebook friends how smart you are by the cool, high tech stuff you read. The button is only on articles from the last two NLs though. We'll be adding it to them all, but hey, this stuff takes time.

And never let us forget to thank the people who paid us good money to bring this stuff to you. Thanks HITEC!

That's it, Enjoy!

Back in 2008, Nuts & Volts sponsored the $100 Workbench Challenge. It was a great success and we had plenty of readers enjoy participating in the contest and showing off their carefully crafted work spaces. With the changes in available tools and technology, we decided to bring the challenge back, but this time even bigger and with a lot more prizes! Our new two-part contest is a combination of straight-up workbench design and a bit of "show and tell."

Solar Tracker
Solar Tracker
After several scrapped ideas for my senior design project, we settled on a solar-tracking power supply that not only provides power to sustain its own functions (tracking the sun for optimal energy collection), but also for propulsion and steering of an unmanned vehicle.

DFT Basics
Experiment with DFT using Excel spreadsheets.
For some electronics hobbyists, the discrete Fourier transform, or DFT, is a feared and mysterious entity that is best left to the "experts" or those who practice in the field of digital signal processing (DSP) on a daily basis...

Simple motor speed control
AVR C Programming Workshop - Part 17
Simple motor speed control
Last time, we tied up some loose ends concerning interrupts, getting numbers from a PC, and optical isolation. So now, let's tie it all together and learn to do some simple motor control.
