PCMCIA - People Can't Memorize Computer Industry Acronyms
Powered By HITEC!

So, according to our stats, the article "What The L Is It?" was the most read article in last week's newsletter, by far. Who knew that measuring inductance was such a popular past time? (Sorry football) How fortuitous that there's a follow up article (Probing Cores) in store for you this week, that builds on that project. And, we have the two linked together in the series tab in the sidebar, so you can click back if you missed it last week.

Also, our really quick survey is back with just 3 questions about building electronics projects. So click on over and get it out of the way, then check out this week's reads.

Click one of the links below to take the survey.

And as always, we say thank you to the hand that feeds us. This week, that hand once again belongs to the great people at Hitec. Thanks guys!

That's it, Enjoy!
How Do You Measure Competency?
Do you consider yourself a competent electronics enthusiast? Competency - a measure of someone's skills, knowledge, and attitudes in a domain - is a term usually associated with work and human resource departments. However, the concept of competency also has merit in the avocation of electronics. But what constitutes competency, and why should you aspire to greater competency?

High Voltage Power Supply

Here are some of the most asked questions about the Workbench Challenge!

Is it hard?  No
Will there be prizes?  Yes
If I win, will I be famous?  Yes   (wait, define famous... then No)
What are my odds of winning?  Good  (Odds go down significantly if you don't enter)
What if I don't have a workbench?  That sucks for you, but you can still enter Part 1.
Does it cost money to enter?  No
What exactly is the Workbench Challenge? Glad you asked. Get The Details

Smiley's Workshop 21 - Breadboarduino
C Programming * Hardware * Projects
There are many folks who are ready to move beyond what Arduino does easily. This leads to attempts to twist the concept all out of shape to make it do things it just wasn't designed for. So, let's bust up the Arduino and reconstruct our own version from the pieces.
