Three Flashing LED Doorbells For The Hearing Impaired
When
the push switch is operated - the buzzer will sound and the LEDs will
begin to flash. For the hearing members of the household - the buzzer
acts as a regular doorbell. It also re-assures the visitor that the
doorbell is working.
When the push switch is released the buzzer will stop - but the LEDs will continue to flash. The length of time they will go on flashing is set by the values of R2 & C1. With the values shown in the diagram - the LEDs will flash for a further 30 seconds or so. If you make R2 a variable resistor, you can adjust the time period. If you want longer than 30 seconds - increase the value of C1 or R2.

The
main difference between this circuit and the last one - is the
addition of the two transistor switches. The switches will each flash up
to 15 groups of 3 LEDs. And - because they are getting power directly
from the battery - the LEDs will glow at their full brilliance.

Animal Friendiy Mousetrap
This mousetrap is built around a PlC12F683 and uses an infrared transmissive optical sensor that is modulated at a frequency of 38 kHz, so that it isnt affected by the ambient light. The modulation is carried out by the PlC, which generates a 38 kHz signal at port GP2, which is connected to the lR LED. The lR receiver is a type that is usually found for use with remote controls. lt reacts only to 38 kHz signals. lt reports the presence of an lR signal to the PIC via port GP1.
When the lR lightbeam is broken the PIC turns of the relay via port GP4 and FET T1 , which: causes the door of the mousetrap to close. The transmissive optical sensor is housed inside a small wooden box. A small amount of food is placed inside this box.
Circuit diagram :
Animal Friendiy Mousetrap Circuit Diagram
When a mouse walks through the light beam on its way to the food it causes the door to shut behind it and an LED starts flashing. The door is normally kept open by the coil of a relay that has been taken apart. When the coil is no longer powered the tin door is pushed shut by means of a spring. A piece of glass or transparent plastic should be put on top of the box, so that the mouse doesnt have to enter a dark space. When a mouse has been caught it can be let free again somewhere outside, some distance away from the house.
The reset button has to be pressed to ready the trap for its next victim. The author has managed to catch a few dozen mice with this device. The program is written in PICBASIC Pro and can be freely downloaded from the Elektor website, it is found in archive file # 100308-11.zip.
