Pentax IR Interval Timer

Posted December 19, 2015 by Chris

"I’m planning a trip to the desert, and one of the things I wanted to make for myself were time lapse movies of sunrise or sunset, and the night sky. My DSLR does not have a wired remote capability and Hoya has decided not to include an interval timer on their low end DSLR….."

Turntable Photography Equipment

Posted August 14, 2015 by Chris

"A friend asked me if I could build him a device that would allow him to take photos of his products in 360 degrees. That kind of photo is actually an animation that consists of several photos of the same product but from different angles. It means that we need a device that can be controllable and that could take pictures on even intervals."

Alphanumeric Optical Endec Transceiver

Posted March 18, 2015 by Chris

"Our goal in this project was to build a pair of high-speed transceivers that could encode and decode optical signals modulated using Morse code conventions."

Whiteboard Erasing Robot

Posted February 22, 2015 by Chris

"The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text."

Machine vision with Python

Posted February 8, 2015 by Chris

"OpenMV Cam gives any project the power of advanced machine vision with the ease of writing simple Micro Python scripts. More than just a camera board, OpenMV Cam is a complete vision solution that uses a simple IDE, rapidly integrates into any hardware project, supports shields for expanded capabilities, and already has a community behind it."

The Ghost In The Field

Posted December 10, 2014 by Chris

" The camera has been fixed in its position and the reader photographed. Using a tag connected to an LED we paint in the edges of the readable volume with a long exposure and animate them to show the form."

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."

Wireless BusCounter

Posted November 19, 2014 by Chris

"I’ve been working on creating a cheap, time-lapse camera that people could use to ‘sense’ the world around them. The cost of such a device would be around $10, when all is said and done, and having multiple of these devices would open up options for public computing that people have not considered – a world where people are willing to deploy “personal, public” electronics throughout their environment with the same ubiquity, recyclability and reusability as paper."

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."
