Several years ago a colleague suggested that I should be using PICs for my hobby, which then was amateur television. I spent many hours developing and experimenting with video mixers, faders and effects (FX) units, and all this was done sing analogue and digital circuits (TTL gates) that took quite a while to get the desired results. I did not kno

w at that time what he was talking about. What were these PIC things What could they do for me, and my hobby How was I going to be able to use them anyway I felt that I was getting on OK with my method of designing and building circuits using conventional integrated circuit and transistors. It was a little later when I was told that I could replace a very complicated video switching circuit (manual and sequential switching) using eight TTL type gates and monostables and many other components with just one PIC chip. It could do a lot more than the printed circuit board full of `standard` integrated circuits too! How was all this possible with just one chip, and how was I able to "tell it" to do anything. I has no experience of microprocessors and programming. I couldn`t even turn a computer on, and when I eventually did, I couldn`t do anything with it, other than stare at the `blinking` cursor (pun intended)! My background is radio and television and during those years whilst others were increasing their knowledge and programming skills with the early personal computers, I was experimenting with video and television circuitry. I had neither the need, nor the interest for programming of any description. My way of thinking about programming and using micro chips soon altered however, when I gained the information how to program and use a PIC to do exactly what I wanted it to do. All my project building is now done with a PIC...
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.....
