Cracking an electronic safe using brute force

Preface There's nothing nefarious here, nor is the information contained herein particularly helpful to thieves or the dishonest. A thief would just cut the dang thing open and be done with it. The story So I bought a fire safe to protect some documents that I wanted protected in the unlikely event of a house fire. When I got the safe, I promptly emailed myself the manufacturer's code, set up an easily reme ...

Control Door Lock Remotely Using Smartphone

Introduction Hi, friends. I came to this idea of controlling a door latch/lock remotely using a smartphone when I saw many people many times forget to carry latch/lock keys when they leave the house for a short trip, or the door gets latched accidentally while casually talking to neighbors, etc. In such cases, there remains no option but to break the lock. Also, sometimes you are inside your bedroom and wan ...

Knock To Open Treasure Chest

Preface My daughter asked me to build her a treasure chest that she could use to store her most valuable things. Obviously she demanded it to have some kind of a locking mechanism so only she could open the box. First thought was to use a keypad but then her grandfather bought her a diary with a secret code. So I had to come up with something else. On Adafruit’s tutorials I came across the Secret Knock Acti ...

How to Text Yourself when your DSC PC1550 Home Security System Alarms

I have a home security system that was installed when my home was built in the early 1990’s. It is, or was until I modified it, a wired perimeter system with a single wired motion detector. The system is a DSC PC1550 and originally was monitored by a well known alarm system service, a three letter acronym beginning with the letter “A”. Anyway I stopped paying for the monitoring long ago. More recently I dec ...

Arduino Bicycle Alarm and Lights

This alarm is a good way to alert you if somebody messes with your bike. I had a bicycle stolen a while back and decided there had to be a better way to keep my bike secure. When I searched for bicycle alarms, all I could find were alarms that responded to sudden movement or when a lock was cut. Also, the reviews of these products rated them mediocre at best and said they often did not work or gave a lot of ...

Build Arduino Based Home Security System Using PIR Motion Sensor

PIR sensors are widely applied in wireless residential security systems, home alarms systems and many more security circuits as motion detector sensors. A typical PIR sensor detects the infrared red (IR) waves from human body and so it is also known as ‘human sensor’. It would be wonderful if we interface PIR sensor to Arduino to get some cheap home security systems, isn’t it? How to Interface PIR Wireless ...

Arduino Security Alarm with Reed Switch

How does the security alarm circuit works? When power is turned on, the circuit goes into standby mode, and this condition is indicated by “SECURITY ALARM” in the LCD screen.Note that here a N/O reedswitch + bar magnet combination is used to detect any mishaps, and hence the reed switch should be in “closed”state at standby mode. When reed switch is opened, pin 2 of Arduino goes high with the help of the pu ...
