Homemade Security Camera based on Raspberry Pi

Posted November 29, 2014 by Chris

"I went a little further by adding an IR LED array that I happened to have lying around…I mounted the camera board right behind it and cut a short length of black plastic tube that fit in the center of the array to prevent back-scatter of light when the LEDs are on."

Picture-Axe, Sound trigger to camera flash

Posted September 29, 2014 by Chris

"Sound seemed to be the logical choice, and google led me to some basic circuits for triggering flashes with sound, but I wanted to be able to control the delay and sensitivity and have different modes and functions. Thanks to LMR I new the solution. Microcontroller! So I started boarding and building."

Motorised Time-lapse Rail with Raspberry Pi

Posted September 21, 2014 by Chris

"There’s another article in the series of photography related DIY projects using the Raspberry Pi single board computer…With all the talk about time lapse rails, I though I’d have a go at building one."

Time-lapse photography: a simple Arduino-driven camera intervalometer

Posted September 13, 2014 by Chris

"While testing my automated critter camera, I was getting lots of false positives caused by clouds gathering and growing and then evaporating away. False positives are annoying, but I discovered that it’s fun watching the clouds grow and change in all those photos … which got me thinking about time-lapse photography."

Arduino – LCD Image Viewer

Posted September 9, 2014 by Chris

"This is a quick project I made to try out a 1.8″ colour LCD display from Ebay, the microcontroller code is very simple, after initializing the display it just waits for serial data and sends it straight to the display. Image processing is done by the host program…"

Robotic Turret With An AVR + Stepper Motor

Posted August 6, 2014 by Chris

"Essentially, I wanted to be able to control a little robotic arm / turret using a PC with a serial port. I thought this was a worthwhile project because I could later adapt it to aim a webcam, Nerf toy gun, or maybe even a felt pen so it could draw pictures."

The OscilloCam

Posted May 21, 2014 by Chris

"This blog serves a narrow but illustrious audience: the photographically inclined electronics hobbyist. Yes folks, I’m going for the masses here:) Kidding aside, if the line above describes you, or even if it doesn’t but you find yourself having to illustrate an article here and there with an analog oscilloscope screenshot, then this article is for you."

How To Build A Witness Camera

Posted May 20, 2014 by Chris

"The Witness Camera is a combination of a VGA CMOS camera, a passive-infrared movement sensor, a 1 GB SD-card (or bigger), and an AVR Mega32 microcontroller implementing a solid-state time-lapse recorder. It is a compact, complete, self-contained surveillance system designed with home users in mind."

Photographing Splashing Droplets

Posted May 11, 2014 by Chris

"Up until now I’ve been using a photogate sensor and the Camera Axe to take pictures of water and milk droplets. After some research I found many – people – online were using solenoid valves to create droplets and take pictures of them. The big advantage to this method is it’s easy to collide drops which is was very difficult and random using my old method."

Inverse Panorama Camera Jig (time lapse rig)

Posted April 7, 2014 by Chris

"This is a simple walk through on attempting to build a quick ‘inverse-panorama’ camera jig for time lapse photography."
