Sensor identifies insulated "hot"-line conductors
Certain situations call for a simple way to find out if a line conductor is “hot” or not. If the conductor isn’t insulated, a popular method is to use a screwdriver with a built-in high-value resistor and a neon tube. The sensitivity of such a device... — Contributing Author

Automatically switch between two serial input devices
Typically I prefer to use the standard serial mouse when working with most programs in Windows, such as Office95, but when drafting with programs like Autocad, I prefer using a trackball. The automatic switchover circuit presented here accomplishes... — Contributing Author

[Ideas For Design]
Low-cost fan manager for power-supply applications
Modern system ergonomics require an increasing amount of electronics to be crammed into ever tighter quarters. Consequently, space allocations for the ubiquitous power supply shrinks. These smaller power-supply form factors, in addition to greater... — Contributing Author

[Ideas For Design]
Specifying frequencies for leakage inductance measurements
In modern high-frequency circuits, the leakage inductance of the magnetic components can be a very important design consideration. However, it’s also important not to hamper the transformer manufacturer with unrealistic testing requirements. A little... — Contributing Author

[Pease Porridge]
What's All This circuits-in-your-car stuff, anyhow?
Hip, hip, hooray. Pease is finally going to talk about electronic circuits. So many of these recent columns have been about things that have nothing to do with electronics. True...Sorry about... — Bob Pease

[Walt Jung Archive: Walt's Tools And Tips]
Readers Respond: Another Mailbag
This month we take a look at some recent mail sent to this column. While a variety has come in, much of it has been concerned with computer-related issues. "Ouch!" you say? If you're worried that that means another round of computer hardware and tech... — Walt Jung
