The International Exhibition of electronic components and technological equipment – ExpoElectronica will take place in Moscow. It is the leading forum of the electronic field, which demonstrates the latest developments of electronic industry and presents offers of the [...]
Company Terraelektronika designed display module TE-ULCD35,the basis of which are 3.5-inch color graphic display with touch screen and 32-bit ARM7-LPC2478 microcontroller company NXP. The module TE-ULCD35 includes:display with a diagonal 3.5 inches 320×240 pixels and touch screen, microcontroller LPC2478: 16/32 – bit ARM7TDMI-S core, 72 MHz, 512 KB Flash-memory programs,98 Kbytes of SRAM,controller, LCD;external NOR [...]
The NP-100v12 is a simple headphone amplifier that allows an entry level builder to experience assembling and listening to their own creation. I use the term builder as electronic experience combined with innovation which allows the creation of a device, rather than simple board stuffing. This amplifier can take on many shapes and sizes; I [...]
As more new televisions are released by the manufacturers, there is a trend to offer them with the Freeview HD digital TV service already installed. The latest television from Panasonic is the S20 and it comes into the range just above the X20 Plasma range of TVs. The Panasonic S20 uses 600 Hz technology, which [...]
The main part of this project is a LCD, PIC16F870 and an oscillator LM311.
The LCD is a standard 2 line 16 chars display connected in 4-wire mode to the PIC.
At the bottom you will find a 4.000 MHz crystal to run the PIC.
The heart of this construction is the LC oscillator based around IC2. The [...]
Reports are coming in from various corners of the net that the latest firmware update for the PS3, version 3.21, is causing problems for some console owners who have applied it.
Firmware 3.21 has already been the source of controversy, as it gets rid of the option to install another operating system that [...]
If you’ve dabbled with PIC18F microcontrollers and the USB Generic HID standard before (perhaps you’ve even tried my Building a PIC18F USB device project) then you will have noticed that there is a lot of complexity in supporting USB on both the PIC18F and the Windows host-side of things. Getting beyond the basic steps of [...]
The new Version 4.0 runs under Linux, Windows and MacOS X and offers an
integrated import filter and export filter for DXF files as standard.
The import of DXF files makes the design of exterior and interior
contours possible without restrictions, which means that the design of
front panels is not limited to simple geometric shapes. Consequently the
design of [...]
Very brief instructable to give a circuit that makes a good simple remote for canon compact camera.
For use with CHDK .
What it does:
Allows both a remote shutter button as well as making it so that any IR remote control (e.g. TV remote) can be used to remote control the camera.

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 [...]
