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, ...

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 ...
