Signaling and The Grapevine[TM]
The Signaling System you have been waiting for!
- Simple electronics: plug and click connections, pre-assembled boards
- Complete! Software includes the knowledge you want for prototype signaling!
- Affordable! Lowest cost system available
- Fast to install! Have your signals working over the weekend.
Fast clock controls in software
-
Each Grapevine Node
contains software to drive a digital clock, and an analog clock
-
Settings are controlled in ProTrak
- Clock software is in Grapevine Node
- Use any fastclock ratio
-
by setting session duration and modeled hours
- e.g. 3 hour, 30 minute session modeling 20 hour day gives a ratio of 5.714
-
or set ratio directly
- Start, Stop, Pause and Reset commands available during operations
Digital Fast Clock
- Digital clock driver-board uses parallel
port from
Grapevine Node (micro-processor)
-
Digital clock display can be any 7-segment display
- Use small displays for panels and larger displays for mounting on room walls
-
Make your own display from individual leds wired to form 7 segments (like scoreboard numbers)
Analog Fast Clock
-
Analog clock uses device port on Grapevine Node
- Make analog clock from any 1.5V battery-driven office clock
-
Modify clock by:
- putting a 0.1 uF cap across the coil
-
330 ohm resistor on one lead
- Remove the battery.
-
Remove the clock lens and pull off the hands.
- Remove the clockwork and pry off the back being careful not to have the gears fly across the room.
-
Find the solenoid and solder a 0.1 uF cap across the leads.
- Drill a 1/4" hole on the side of the case near the solenoid.
-
Solder a couple of long leads (e.g. phone wire) on to the solenoid terminals.
- I put the 330 ohm resistor on the free end of one of the leads. The resistor
could also be glued into the clock
