FAB ACADEMY 2015-Paul K. Rutto 
FAB ACADEMY 2015-Paul K. Rutto Am Paul from Nairobi, Kenya.My final project is about a standalone home alarm system.My project covered electronics design,input and output devices ,electronics production,3D printing mechanical design(it has a push button),embedded programming computer aided design.
The project cost 11USD
.I intent to apply for license from the government so as i can produce mass production of the same
.I plan to do more research on it and participate in exihibitions and make it open source software
.I designed the schematic diagram with Eagle as usual as shown below
the components to be used are available in the schematic diagram below
PARTS LIST:motion sensor,PCB voltage regulator(7805),transistor Tip 122,buzzer,jumper wires,ordinary diodes,1k and 1ok resisistor,Attiny 44 microtroller, solder wire,20 microfarad capacitor,programmer and PC.
The board as shown below
The circuit for the alarm as Shown below
Programming the alarm as showm below
Programming the alarm as shown below
I design the cover or the discase with rhino as shown below
I 3D printed above alarm discase with 3D printer as usual
Here is the stand alone alarm with everything inside.The board encloses alarm board,9v battery to power the system.The alarm detects a motion through an inbuilt motion sensor and gives out a siren.This alarm can be used in home to prevent intruders in homes
. Download CAD file for the discase.
Download CAD file for the discase.
Download CAD file for the discase.The discase will house alarm board
