The purpose of this project is to construct a computer that uses the combined computational power of many microcontrollers (MCUs). All the MCUs cooperate to solve one problem. The computer is defined as parallel processing machine and the algorithms that are executed on it are called parallel algorithms . The machine can be used as an educat

ional system that will help the development, understanding and fine-tuning of many parallel algorithms. It can also be used to achieve high performance in many cases such as in Digital Signal Processing. The computer can be easily constructed by an amateur. However the efficient use of it requires more effort as the development and implementation of parallel algorithms is a rather difficult task. The next section makes a brief introduction to parallel processing computers. Section 3 describes the hardware, while section 4 describes the supporting software (i. e. the software that runs on the PC plus the firmware that lies on the "parallel computer" board). Section 5 explains and demonstrates some parallel algorithms that run on this parallel computer. Finally, section 6 holds the conclusions. The source code of the samples is held at compressed file " ParallelPIC_examples. zip ". The code for the supporting software that runs on the PC is stored into file " ParallelPIC_PCcode_V2. zip " and the source code (and the hex files) of the firmware is stored into the file " ParallelPIC_firmwareV2. zip ". This parallel computer is of type Single Instruction Multiple Data (SIMD) which means that all MCUs execute the same program, but each MCU works with different data. (As a matter of fact, there are time instances where only one subset of the MCUs executes actual code while the other MCUs do nothing. This is inherent in some...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
