Meeting-Minder
By: Steve Hageman
The meeting timer: This project came about because we were having way
too many long meetings that did not hold to the agenda. A planner
suggested that he was going to get one of the light towers that we
use on the equipment that we build and wire some manual switches to
it. I suggested "Let's go hi-tech" and added a PIC with LCD display,
automatic timing and NICAD battery operation.

The result was the
"Meeting-Minder". The Minder operates very simply,
- Turn it
on.
- Set the agenda
time required (by rotating the big knob) so that the minutes
desired reads out in the LCD display.
- Press Start when
your ready to go.
- The Green "OK to
Talk" light turns on.
- The PIC now
counts down the time remaining for the agenda item.
- When 3 minutes
remain, the Green light goes off and the Yellow (Warning, time is
running out) light goes on.
- When the three
minute warning is over the Red light starts flashing for 10
minutes then the Meeting Minder turns off and goes to sleep (every
thing goes off here to save the battery).
- At any time the
during the time count down period the start button may be pressed
to pause the count down, all lights go off and the unit waits
until the start button is pressed again, then it continues the
count down.
- If the Reset
button is pressed, the unit turns off all the lights and waits in
the input loop for the next agenda item time to be entered.
- The meeting
minder runs for about 8 hours on a single charge and recharges
after being plugged into a "wall wart" over night.
