What is "Static Code Analysis"?
It's when you build and run your code on a test board, then shuffle around on the carpet, rub some balloons on your hair, then touch the chip and see how the code works...

What kind of sex do you prefer?
Another reason for preferring male pins on boards:   Male board header:  $0.40 Female ribbon cable receptacle : $0.52 Total connector cost:  $0.92   Female...

What kind of sex do you prefer?
Obviously if you're stacking boards you have to have both - one board of each type - but for me if it's cables, it's always male on the board, female on the cable.  Look at...

AC / DC coupling in oscilloscope
There are times and places for AC coupling over and beyond that, but generally, you're right, AVRcandies.  I run my 'scopes in DC coupled mode about 99.5% of the time. ...

AC / DC coupling in oscilloscope
I might suggest that the rectified AC also has caps on it to make a nice stable DC voltage - which will be invisible on an AC trigger.   Rule o' electronics:  A perfect...

AC / DC coupling in oscilloscope
This is a job for Google.   Short answer:  AC coupling your scope probe puts a small capacitor in series with the signal.    If you don't know what that does,...

flashing AVRs at high speed
I went snurfling around in my collection of AVR spec sheets and found some that state "20 years at 85C" and "100 years at 25C" data retention times.  'course, there's a...
