This post will describe how I inspected the IP traffic of a cheap pan/tilt IP camera. Then continued to open the camera up, connect to the serial console of the SoC; extracted the root password and logged in via telnet over the wireless interface. My goal was to have a look at the security of these very cheap IoT devices, and see how they could be improved. Let’s have a look at our victim: I present to you ...

This project allows you to build you own  CCTV switchbox, that you can use to connect up to 6 cameras to a single screen. The camera signal  (CVBS over CInch or any other) is switched to the output using SPDT  or even  SPST relays.How it works ? - by default the controller will cycle through all 6 channels  at a speed which is adjustable by a potentiometer.   This controls the time which each of the cameras ...

What if you could cure blindness as easily as turning on the lights? That’s what one doctor and his team are hoping to achieve with a clinical trial that uses a new form of retina implant to return sight to patients who have lost the ability to see. And for one of the six patients, it’s been a pretty incredible journey. Rhian Lewis was just a toddler when her parents noticed she had trouble seeing in the da ...

The aim of this project is to give private persons, educational institutes and companies access to a portable, affordable and customizable thermal imaging plattform. There are various applications like finding heat leaks in the insulation of buildings, the analysis of electrical or mechanical components, the detection of persons / animals or even mounting it on a drone, together with the additional video ou ...

Freeze moments in time to easily produce extraordinary close-up pictures with your digital camera, an Arduino, and these simple circuits. I have always been impressed by high-speed photography. The photographic capture of what normally goes unseen, or at least unnoticed, is intriguing and oftentimes beautiful. High-speed cameras, however, are expensive and beyond the reach of many of us. You can, however, g ...

The idea behind this project was very straightforward: design an inexpensive remotely controlled system capable of taking still pictures and uploading them to a remote file storage with a camera to be activated by either remote commands or sensor events. And after numerous brain storms the following solution has been found.In base configuration the system comprises of at least two parts: main (MCU) and tran ...

Based on 1.1-µm pixel technology, the AR1335 CMOS image sensor from ON Semiconductor provides 18% better sensitivity than previous-generation devices, along with increased quantum efficiency and linear well capacity to enable near-digital still-camera quality and low-light imaging on smart-phone cameras. The sensor’s pixel and color filter processing increase sensitivity, allowing more light to be captured ...

I  did the following steps: 1) Hardware: Connect the MLX90614 (refer to the datasheet) as follows: Pin 1 on MLX (SCL) connect to ANALOG pin 5 on Arduino Pin 2 on MLX (SDA) connect to ANALOG pin 4 on Arduino Pin 3 on MLX (VDD) connect to 3.3V on Arduino Pin 4 on MLX (VSS) connect to GROUND on ArduinoNow use "pull ups" on the SCL and SDA lines by connecting a 4.7K ohm resistor from the Pin 3 VDD line to the S ...

As automotive electronics takes center stage at Electronica this week in Munich, a "microcamera" module recently designed by researchers at the Fraunhofer Institute for driver-assistance applications is expected to enjoy the spotlight. The Ottawa embedded vision IP vendor CogniVue and Berlin's Fraunhofer Institute revealed Tuesday that they have collaborated on development of the microcamera. It uses CogniV ...

Intervawhat? An intervalometer is a camera controller that signals the camera to take a picture after some set interval. This is really useful for creating timelapse videos. For a long time, I used my TI-89 calculator to create timelapse videos with my Canon digital Rebel XTi. It worked quite well, and the calculator in/out port just happened to be the same as the Canon remote shutter port, so there wasn't ...

I own one of these small action cameras (SJcam SJ4000). I bought it because it’s small, and easy to take with you wherever you go. To make nice stable videos I mount it on a mini tripod. This got me thinking that it would be fun to have a little motor between the tripod and the camera to slowly pan the camera. I happened to have a couple of 28byj48 stepper motors laying around, these little steppers motors ...

Simple digital cameras can produce remarkably good quality photos and are now cheap enough that it doesn't hurt the wallet too much to buy one with the intention of modifying it for use in a project. You may even already have an old digital camera that you don't mind sacrificing for a good cause! Modifying a camera to control it from an Arduino opens up a world of possibilities. This project lets your Ardui ...
