On this page you will find the technical information for building the electronic control unit of my homemade film processing machine. To see the rest of this film developing apparatus, look at the relevant article in the photography section of this site. Developing a color film is a simple procedure of putting it in a […]

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

Background During the Christmas holidays 1997-1998, I started on a small project, trying to generate a video signal with a PIC16C84. I had seen some video clock generating video signals in software, and thought it was a quite interesting idea, and wanted to take it a step further. I didn’t know much about video signals

The Microchip PIC32 is a family of complex and powerful microcontrollers that can be purchased for less than $10 in quantities of one. This microcontroller offers many peripherals useful for mechatronics purposes, such as several channels for analog-to-digital conversion, digital I/O, synchronous and asynchronous serial communication, pulse width modulation, etc. For our purposes, the primary

The synchronizer ensures a contact-free, optical synchronization of external photographic flashguns. The triggering of the external flash is derived from embedded flashes of a camera. It can be used for both digital and “analogous” cameras or for a remote synchronization of the actual flash units. Its use is optimal especially with digital cameras (DC), where

Week 01 August 15, 2010 (2 hours): Met as a team after class to finish writing preliminary project proposal. January 17, 2010 (2 hour): Brained stormed the possibilities of developing a multi-touch table. The Multi-touch table would require an external camera as an interface for the Computer Vision Algoithm. I researched that algorithms that fall

PC Interfacing a GameBoy Camera Here’s another past project of mine from a couple of years ago. At that time I was looking for a low-res camera for simple robotics image processing, and all I had experience with was PIC (12, 16, and 18) microcontrollers. So I didn’t really get to work on the images real time (not enough

An elderly, but still sought after Marantz CD63SE was bought into the shop last week, with the fault reported that CD’s would no longer play. After approximately 15 years of use, this is a common situation, as the laser power will gradually reduce over time to the point where it can no longer focus reliably

This 2004 vintage Arcam CD73 came into us with the reported fault that it would no longer play CD’s, or even read the table of contents. Given that it is over eight years old and had plenty of use in that time, we were not surprised to find that the laser had expired and needed
