This post describes the design and construction of a 3-phase loudspeaker intended for Leslie Speaker emulation. The unit is intended to be driven by a 3-channel audio amplifier The Brute, which in turn is controlled by LEMS, a micro-controller based control system, the construction of which both are described in companion posts. Companion posts are […]

The recent trends in the advanced technology are helpful in developing most advanced electronic gadgets. Most of  these electronic devices are developed using microcontrollers. The microcontroller is an electronic component, which is programmed to perform various control operations. There are various kinds of microcontrollers available, such as 8051, AVR, ARM, and PIC microcontrollers, etc., which […]

This post provides the solution for using the PIC controller UART interface (e-g to connect PIC controller with PC using serial adapter). Complete code and simulation can be downloaded from the ‘Downloads‘ section at the bottom of this post. The following figure shows the result of simulation of PIC UART in Proteus7.6. In the main […]

JeVois, which can be translated from French as: I see, is an open-source quad-core camera that can be connected easily with your project whether you are using Arduino, Raspberry Pi or just running it on your PC. JeVois contains a video sensor, quad-core CPU, USB video and a serial port in only 1.7 cubic inches. […]

Traditionally, asic developments are thought to be the domain of high volume applications. Whilst these designs grab the headlines there are many designs that are successfully undertaken for smaller volume product markets. An example of this is the mixed signal asic for industrial controllers. These controllers cover many industries and come in many forms. The […]

Without problems and directly at connecting a device. How? With a new Euroclamp MPF03 terminal block with integrated fuse holder. Nowadays, when “almost everything” works on electricity we can see still more devices connected to mains line. That´s why it often happens, that many small-power devices are connected to one (circuit breaker fused) line. To […]

With a little practice, you can make excellent double-sided PCBs by combining a laser cutter with chemical etching. The basic idea is: the laser cutter blasts away spray painted etch resist, then chemicals eat away the exposed copper. Once the copper is gone, the underlying board can be cut again with the laser to make […]

A processor is a collection of logic circuits that is designed to efficiently process data. There are a number of processors – processor designs are created for specialised tasks, these include the Central Processing Units (CPU), Graphics Processing Units (GPU), Physics Processing Units (PPU) or Digital Signal Processors. An array or vector processor solves computational […]

Several automated and semi-automated devices require a message to be displayed in order to indicate their working status. In continuation to LCD interfacing with PIC18F4550, this article explains how to display a message or string on a 16×2 character LCD. Programming steps: ·         Configure the LCD. ·         Store a string in a character array. unsigned […]

The PIC16F170X/171X family features Core Independent Peripherals, such as the Configurable Logic Cell (CLC), Complementary Output Generator (COG) and Numerically Controlled Oscillator (NCO).  These “self-sustaining” peripherals take 8-bit PIC® MCU performance to a new level, as they are designed to handle tasks with no code or supervision from the CPU to maintain operation.  As a […]
