The high speed scanner in the video above easily allows the user to digitize books using a flip-book style scanning process which can process 200 pages per minute. The camera prototype rig captures 500 frames per second at 1280×1024 pixels. The trick is in the two optical capturing modes of each frame. See Video..

This project allows instant start sequentially but a dozen low-voltage lamps 12 V / 60 W, and makes them fade and always sequentially (but slower). This system has been designed to meet the demand of a visitor who wanted ten recessed low voltage spot in a driveway to his house, with the following function: – [...]
This circuit allows switching on a LED when the battery voltage (12V) drops below a certain threshold. The operating system is based on a comparison of tension, which comes in a zener diode. If the supply voltage is 12V and the zener diode is a 10V model (this is the case in the diagram), we [...]
This is a good looking and practical device that can be useful in many areas where countdown timer is needed. This project is based on the PIC16F84A microcontroller. The time range can be adjusted between 1 and 999 seconds. This project has 3 buttons and one of them is named Set Button. In order to [...]
A VU meter is often included in audio equipment to display a signal level in Volume Units; the device is sometimes also called volume indicator (VI). In this project we are building a basic and low cost LED VU Metre circuit . The extent (range) display is -18 dBu to +3 dBu, spread over [...]
Today we have a new category “Projects” and a new electronic project 12 Channel LED Chaser with PIC16F84A.
This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. The [...]
