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, ...

Repair of Arcam CD73 laser mechanism

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 replacing. We are more than happy to repair quality hi-fi rather than throw it away, as with a new laser this CD73 will give many y ...

Photomultiplier Tube (PMT) Controller Circuit B using pic-microcontrolleroard

The four channel PMT controller board is a PIC microcontroller based device that communicates with a PC by USB as an HID device and with a PIC-based "hand unit" via PIC-to-PIC RS-232 protocol. These two external inputs (USB and RS-232) send strings to the PMT controller that: Sets the four high voltage levels of the PMTs Provide four bipolar offset voltages for black level adjustment on an external amplifie ...

Zeus: trigger your camera with lightning using pic microcontoller

Introduction I have always been fascinated by photographs about lightnings. While it is relatively easily to put a lightning strike in any photograph using image editing techniques :) I still prefer the real thing. Since photography is a hobby of mine, I wanted to be able to photograph lightnings. However, when I tried to do it without any specialized equipment, I didn't have much success. Reading a bit abo ...

Crossed IR Beam Camera/Flash Trigger

This device will trigger a camera or flash unit to automatically take a picture when an object (target) enters a specific location. It uses two, crossed infrared light beams to detect the presence of the target and close a relay that trips the camera or flash unit. Response time is about 2 ms from detection to relay closure, so if your camera doesn't have long shutter-lag, it will capture even fast moving t ...
