The Wire Between Multiio Card & Joystick Connector - Some PC
multi-IO cards have a 16 pin header in the circuit board which is wired to
the joystick connector (fitter to other slot place) using flatcable. The
wiring is straight one-to-one connection but, due to the different
numbering scheme of the gameport connector vs the 16-way header, the pin
numbers don't necessarily match....(design idea 07/03) |

Transmitter accurately transfers voltage input - 15-May-03 Issue of EDN
When you connect remote sensors to a central process controller, a simple, robust, and
commonly used interface is the 4- to 20-mA loop. The advantages of this current loop
include the simplicity of just two twisted wires that share both power and signal, the
loop's high noise immunity in harsh environments, and the de facto loop standard
within the process-control industry.... [Design Idea by Clayton Grantham, National
Semiconductor, Tucson, AZ] |

Tricks improve on Excel LCD initialization - 11-Apr-02 Issue of EDN A
previous Design Idea on using Excel for LCD initialization relies on the user for
cutting and pasting from Excel into an editor (Reference 1]. It appears that it would
take a minimum of six keystrokes or mouse strokes from one character to a new
character to perform this operation. This procedure does not allow for the
addition of comments, which would be advantageous in the maintenance.... [Design Idea
