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...
