Servo Camera Switch using PIC12F675 microcontroller

This document describes the complete design for a camera switch that uses a servo to activate the shutter. This page include links to the complete circuit diagram, the .HEX file required to program the 12F675, and complete construction details. The switch consists of a PIC and a small number of standard components. The Servo Camera Switch connects inline between the receiver and the servo and manages the op ...

Photo film processor

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 sequence of several chemical baths, for reasonably precise times at reasonably precise te ...

Turntable Photography Equipment using PIC16F84A

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. UPDATE: English version of software is now available for download h ...

How to generate video signals in real-time using a PIC16F84

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 back then, I basically just had seen how a single scan-line works. But during the spring ...

Introduction to the PIC32 using pic-microcontroller

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 advantages of ...

A Programmable Optical Slave Flash Trigger for Digital Cameras with Processor PIC 12F675

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 extraordinary adaptability for different systems ...

Tejas Kulkarni’s Lab Notebook using pic microcontoller

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 under Image processing and Computer Vision such as blob track ...

PC Interfacing a GameBoy Camera using PIC18F4620 microcontroller

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 RAM or speed, and I could not find any suitable SRAM around at that time). I thin ...

Marantz CD63SE laser transport mechanism replacement

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 on the spinning CD disc – however with the easy availability of VAM1202 CD mechanisms for below £20, ...
