How to construct a circuit on veroboard by reading the schematic. If you`re an experienced constructor, then you will just look at the schematic and start assembly. Experience tells you where to place components and use veroboard space to its best advantage. If you are a beginner, certain prerequisites are assumed. You need to be able to read the

circuit diagram and relate to each component on the diagram, as it is wired onto the veroboard. For those who are unsure, read my articles on reading a schematic and electronic components. You also need to be able to solder, and beware of the position and orientation of the board and components when working on it from the reverse side. The circuit of the bench amplifier is chosen to represent this article. The notes for this particular circuit are in my test gear section. The schematic is shown below : A suitable piece of veroboard is used. This must be large enough to hold all the components of the circuit. They are available in standard sizes, the piece below is 9 holes wide by 25 holes long and approximate dimesions 1 by 2. 5 inches. Each of the horizontal 9 strips is known as a "track". A track is the same as a single wire running from opposite ends of the board. If a track is broken, with a drill bit or veroboard cutter, then you have two non-connected wires on the same horizontal strip. Note that NO continuity exists across adjacent tracks. If this should happen, i. e. when cutting a track and a piece of copper "swarf" should accidentally bridge two tracks, then the design would be compromised and probably not work at all. Therefore take care when breaking tracks and examine the board after making each break. Check that the veroboard is large enough. Loosely push all components through the holes (in any order).

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.....
