Developed on Hackaday: First Version of the Hardware

Security – Safety Projects / By

The Hackaday writers and readers are currently working hand-in-hand on an offline password keeper, the mooltipass (click to see the project description). Next in our Developed on Hackaday series, we present the first version of our schematics. There’s already been a lot of discussions going on in our dedicated Google group, mainly about the project’s basic functionality. […]

speaker box alarm

Cat Repelling PIR motion sensor (covert) speaker box alarm using Arduino

Projects, Security – Safety Projects, Sensor – Transducer – Detector Projects, Sound – Audio Projects / By

This is a PIR motion sensor device that works with the arduino uno. In order to make it covert enough to be placed in multiple settings and portable enough to fit most places, I decided to make the case for it appear as a speaker. The inspiration for this project: My cat is a jerk. One of his

Security / Automation Sensors using Arduino

Security – Safety Projects, Sensor – Transducer – Detector Projects / By

Security system sensors such as motion detectors, reed switches, pressure mats, glass-break detectors, infra-red beams, and conductive film can be very handy for all sorts of things including home automation systems, interactive art installations – and sometimes even security systems! Almost all security system sensors provide a simple switched output that changes state based on

Sunrise Alarm Clock

LED Dawn / Sunrise Alarm Clock, Nightlight & Security Light – Arduino Compatible

LED Projects, Security – Safety Projects / By

As the nights gradually lengthened in autumn 2011, I discovered the joys of Arduino and thought that it would be a great way to implement something that I have wanted for a long while – a gentle way to wake up on a winter’s morning.  Sadly, it has taken me over a year to find

Arduino Sentry Gun

Building a Sentry Gun with Laser Trip Wire System and Arduino

Home Automation Projects, Projects, Security – Safety Projects / By

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC. Concept: Trigger gun when laser is blocked by intruding object. Note: Tilting is included for expandability but not used in this project. Skill Level: Basic soldering and basic metal works Things You Need: Toy Gun(Any will do, preferably a semi-auto) Continuous Rotation

Arduino Double Dice Jewelry Box w/ Secret Switch

Arduino Programmer Projects, Home Automation Projects, Projects, Security – Safety Projects / By

This was a fun project. Push the red button, watch the dice ” ROLL ” then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone board. Powered by 4 AA NiMD batteries. Can you find the SECRET SWITCH in the main picture? Where is
