If you prefer a version that is quicker and easier to build, but which doesn`t have quite the same final appearance I highly recommend the Breadboard Six Transistor Radio Kit. It is also slightly cheaper. This is a MW AM transistor radio which can be constructed without soldering using 3A terminal strip. It is a modern response to the 1971 Ladybird Book Radio and works as well

as some AM radios that you could buy in a shop. It`s best to read right through the construction notes first before starting out. Why is it called a Choccy Block Radio Kit Choccy-Block is the nickname for the terminal strips on which it is constructed, and they look rather like chocolate bars. I supply a kit of all the electronic parts, wire, terminal blocks, knobs, mounting screws and a cardboard enclosure for this design with wires soldered on to some parts where necessary. I`ve assumed that you have a small screwdriver for the terminal screws, a fine point marker pen, some small wire cutters for trimming the component leads and some means of stripping the insulation from the wire. A craft knife is good for that. You will also need some paper, glue, scissors and sticky tape. It is best to mount up the radio in an enclosure when it is all working. The cardboard container supplied is pretty good to start with, or you might choose to use some other method. The components list has links to photographs that should allow you to make sense of the different values and to identify which leg is which. You need to know about resistor colour codes and you can find that information in many places. It should be possible to build the radio just by looking at the pictures, but later on I`ve included full electronic explanations. If those don`t make any sense, don`t let them put you off just building the circuit. The schematic diagram...
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.....
