Home		Yes/No eBlock Systems Project Description eBlocks Required Schematic Garage Door Open at Night Alerts the homeowner if the garage door is open at night. magnetic contact switch light sensor 2-input logic block wireless transmitter wireless reciever green/red led Cafeteria Food Alert A food service line worker can indicate to the kitchen when a particular item needs replenishing. button led 2-input logic block toggle splitter Disabled Student Teacher Caller Alerts the teacher if a student needs help. button wireless transmitter wireless reciever led Object Locator The object we are looking for (remote control/keys/etc) is equipped with a beeper. We have a main controller where we press a button causing the missing object to emit a beeping noise. button wireless transmitter wireless reciever beeper Ignition Illuminator Turns on a light pointed towards the ignition to make inserting the keys into the ignition at night easier. magnetic contact switch light sensor prolonger 2-input logic led Mail Notifier Indicates to the homeowner when the mail has arrived. light-beam switch wireless transmitter wireless reciever green/red led Night Lamp Controller Turns lights on at dusk and keeps them on until a predetermined user defined time. clock timer electric relay Front desk notifier A company may want its receptionist to be free to move about the office. When someone enters the lobby the receptionist is alerted with a portable device that blinks an LED or emits a soft beeping sound as not to disturb others working in the building. button prolonger wireless transmitter wireless reciever beeper Entry Gate Detector Indicates if there is a car waiting at an entry gate. motion sensor wireless transmitter wireless reciever beeper Parking Assistance Aids the user in parking by alerting a driver when they have pulled into the garage far enough to close the garage door or to a user defined point in the garage. light-beam switch inverter red/green led Cabinet Lockup We have liquor/chemicals/etc in a cabinet and want to restrict access to them. We build a system that requires a correct code to be entered before opening a cabinet. 10-key entry electric lock 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. (Number podium timer design also available) button prolonger led/grled splitter (optional) inverter (optional) 2-input logic (optional) Mail Box Open at Night Alert If the mail box is open and it is dark at night, sound an alert inside the house to alert the homeowner. contact switch light sensor 2-input logic block wireless transmitter wireless receiver beeper Copy Machine Available Detect if the shared copy machine is being used. If the copy machine is available, turn a green light on in the hallway (or room somewhere). If the copy machine is being used then turn the light red. motion sensor prolonger wireless transmitter wireless reciever inverter green/red led Water Alert Indicate if the washer is leaking or if a pipe broke in the basement while the homeowner is away. water sensor internet status or telephone status Visual Door Bell We don't want to wake a sleeping baby so we implement a visual door bell. button wireless transmitter wireless reciever prolonger led Dark Room In Use We want to alert others that the dark room is in use so we use a light which turns red when the dark room is in use and the light turns green when the room is not used. yes/no switch red/green led Laundry Alert Build a system that alerts the user when the laundry is ready. sound sensor wireless transmitter wireless reciever beeper Gardener Access The gate to the backyard is locked. We want to build a system which allows the gardner to have access to the backyard without providing them with another key. 10-key entry electric lock Doorbell Extender We want to build a system in which we can hear the doorbell even if we are working in the backyard or at a neighbor's house. sound sensor motion sensor (optional) 2-input logic (optional) wireless transmitter wireless reciever prolonger buzzer Carpool Alert We are part of a carpool. Instead of the driver having to get out of the car and ring the doorbell or honking, we want to build a system in which the carpool driver can alert us that they have arrived. button wireless reciever wireless transmitter 2-input logic toggle buzzer 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. (Number remote ceiling fan design also available) button toggle wireless transmitter wireless reciever lightswitch Package Delivery Sometimes when a package is delivered when we are not home it is left on the side or back porch. We want to build a detector which will indicate if someone has been on the side or back porch while we were not home. button motion sensor once yes, stays yes led
