Schematic |
|
Podium Timer |
We have a series of timed speeches and want to display
the remaining talk-time and a timeout red light on a
conference podium.
(Boolean podium timer also available) |
- button
- toggle
- seconds timer OR up/down timer
- splitter
- constant
- range OR threshold
- integer display
|

|
Anonymous Voting |
a lecturer may want an audience to anonymously express
their opinion on matters raised. Each student is given
a device to cast their vote and the results are
displayed/reported to the lecturer. |
- yes/no switch
- equation/math block
- splitter
- constant OR inverter
- integer display
|
|
|
Customer Monitoring |
A store owner may want to monitor where customers
spend their time. Motion sensors can be placed
throughout the store to keep track of which part(s)
of the store customers visit most frequent. |
- motion sensor
- wireless transmitter
- wireless receiver
- button
- turnstile counter
- integer display
|
|
|
Temperature Alert |
We have plants/pets/bread in a room that is affected
badly if the temperature becomes too hot/cold. We can
build a system that sounds an alarm if the temperature
in a room exceeds a user-defined threshold. |
- temperature sensor
- constant
- threshold
- beeper
|
|
|
Plant Experiment |
We want to build a system for the local science fair
that automates a plant-growing scientific experiment
that turns on a fan whenever the temperature exceeds 90
verses a plant with no fan. |
- temperature sensor
- splitter
- button
- turnstile logger
- constant
- threshold
- electric relay
|
|
|
Temperature Tracer |
At certain intervals we want to sample the temperature
and log it. |
- temperature sensor
- button
- turnstile logger
|
|
|
Garage Open vs. Garage Closed |
Monitor the time the garage is open verses the time the
garage is closed. |
- magnetic contact switch
- splitter
- button
- inverter
- seconds timer
- integer display
|
|
|
People Counter |
Every time a light beam is broken it triggers a counter
to increment. This counter value is then displayed (or
logged or both). |
- button
- splitter
- light-beam switch
- turnstile counter
- integer display
- turnstile logger
|
|
|
50 yard dash |
We have 2 light beam switches. When the first switch is
broken the timer starts. When the second light beam
switch is broken the timer stops. A button is connected
to the rst of the timer to zero out the value. |
- light-beam switch
- 2-input logic
- toggle
- button
- updown/timer (or seconds timer)
- integer display
|
|
|
Kitchen Timer |
Set a timer, when it reaches zero turn an alarm on. |
- button
- toggle
- up/down timer
- beeper
|
|
|
Video Game Timeout |
We want to control the amount of time TV is watched or a
video game is played. We require a code to be entered on
a key pad which will turn power on to the TV for a
pre-determined amount of time. |
- 10-key entry
- button
- seconds timer (or up/down timer)
- splitter
- constant
- threshold
- electric relay
- green/red led
- integer display
|
|
|
Retainer Reminder |
We want to build an alert system which indicates when a
person has left their retainer behind. |
- yes/no switch
- wireless transmitter
- wireless reciever
- error detector
- button (optional)
- toggle (optional)
- 2-input logic block (optional)
- beeper
|
|
|
Remote Ceiling Fan |
We like to leave the ceiling fan on when we go to sleep
at night but it often becomes too cold. We want to build
a system in which we can turn off the ceiling fan
without having to get out of bed and turn it off in the
middle of the night.
(Yes/No podium timer design also available) |
- button
- toggle
- wireless transmitter
- wireless reciever
- lightswitch
|
|
|
Weight over time |
Logs the weight of an object over time. For example, we
are doing a science fair experiment in which we monitor
a glass which contains water. We want to measure the
rate of evaporation and thus measure the weight of the
container over time. |
|
|
|
Pressure Threshold |
Indicates when pressure on an object exceeds a user
defined value. |
|
|
|
Irrigation Monitoring |
Monitor the amount of water given to crops/grass in
different locations - log the amount of water and the
time recieved in various sections. |
|
|
|
Voice Activated Lights |
Turn different lights on depending on a voice command. |
|
|
|
Gameshow Buzz In |
We are playing a game in which we have 3 buttons for
players to ring in. We want to set up a system which
indicates which of the 3 players hit the button first. |
|
|
|
Counting Cars |
We want to keep track of the number of cars that pass
through an intersection. |
