I used a 1.5k source resistor bypassed by a 1000 uF cap.  The drain load
resistor is 3.9k, and the supply voltage is 9VDC.  The 3 caps are ...

Knowing the voltage across a diode, I need to determine the current through
it with a fair degree of accuracy over a range of about 1000x.  Is any one
type of diode better than another in terms of the accuracy of its
logarithmic voltage gain with increasing forward current?  This ...

Currently on a shelf I have full subscriptions of Jan97-Oct03 of
Electronics Now/Poptronics/Nuts & Volts that are all in very good

I want to build an small data logger based around ATMEL's 8535 (or one of
the AVR Mega).
I need to log around 300MBytes of data. USB memory sticks are cost effective
storage mediums. Is there a simple way to interface a USB memory stick with

i want to build a polarity reverser circuit that reverses the polarity
on my saltwater chlorinator as this keeps the salt cell clean.
i want something that changes the polarity every time the clorinator
turns on, it is on a timer with the pool filter and runs every day.

I have an 17 inch LG monitor about 18 months old.
The there is a intermittent/partial break in the "blue" wire in the VGA
