A computer lets you make more mistakes faster than any invention in human history - with the possible exception of tequila.
 
How has electronics changed your world?
Of course, we all know the impact that computers, cell phones, and other electronic devices have had on the way we live. This week, we'd like to hear how you've used your love of electronics to make the world a better place.

If you work(ed) in electronics as a career
, what project have you worked on that's had the greatest impact on others? 
  
If you are a hobbyist, what favorite project have you worked on or built that has helped improve your own or someone else's life?


Congratulations
to shadowchb, the winner of our last newsletter's storytelling prize. Just like Jim before him, shadow will be getting an R Cube talking alarm clock kit from our stash. It's fun to build and does some pretty cool stuff. Since we still have a few more left, we'll keep it going until they run out. All you have to do to be eligible is participate by clicking the link above and sharing your story with us. The winner is picked at random from those who comment on this week's question.  
 
And welcome back to Scance (formerly Scannable). Check 'em out below!
 
That's it, Enjoy!
Change the World

While there's satisfaction from getting an LED to blink five times in a row in response to a button press, it isn't going to change the world - that is, unless you set your goals higher. What I'm suggesting is that you take your knowledge of electronics - whatever your level of expertise - and focus it towards solving a meaningful problem.

Spice Up Your PC    
It just isn't always practical to build a circuit just to experiment with it. Luckily, with a PC, you can simulate nearly any circuit you can imagine with better results than you might expect.

Stop by our Tech Forum and weigh in on some issues. We know y'all got skills and opinions. This is the place to share some knowledge or play Stump the Nuts & Volts Readers.
The High Voltage PIC
The High Voltage PIC - Part 1
 
Can you generate 200 volts DC from a five-volt DC PIC power supply? Yes, you can! In this two-part series, we will build a 200 volt DC boost power supply driven by an 18F2455 Microchip PIC microprocessor. The completed power supply will generate between five and 200 volts DC from a five volt DC input.

C Programming * Hardware * Projects


Our last episode finished the LCD Navigator Project Kit by learning how to use the navigator buttons with our hard-won knowledge of C bitwise operators. So now, we'll start to learn about C pointers, arrays, and structures.

Understanding Digital Logic ICs
Understanding Digital Logic ICs - Part 3
It is usually a fairly simple matter to design logic circuitry using "74-series" TTL ICs, provided that a set of TTL basic usage rules are observed. Assuming that the matter of fan-in and fan-out has already been taken care of, four other basic usage themes remain: Power Supplies, Input Signals, Unused Inputs, and Interfacing.
