This is a very simple ring modulator circuit which will allow you to make interesting analogue sound effects using two audio sources and some kind of amplifier or recording device. Almost everyone has access to a couple of mp3 players and some powered computer speakers nowadays, so this is quite an easy way to go about it. One very familiar use fo

r this old style of ring mod is that which produces the "Dalek" voice. I will concentrate on that application in the text, but there are other effects you can produce which I`ll discuss later. I supply a kit of all the electronic parts in the list above, or you can buy your own. I`ve assumed that you have a small screwdriver for the terminal screws, 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. It is best to mount up the circuit in an enclosure or nail it down to some wood when it is all working, and the holes in the terminal strips make that easy to do. This is a nice simple circuit which you can make pretty much just by looking at the final picture. The components list has links to photographs of the components. I`ve included a full electronic explanation later on. If that doesn`t make any sense, don`t let it put you off just building the circuit. Using a craft knife or scissors, cut the terminal strip into two pieces of two terminals and two pieces of three terminals. The four diodes can then be assembled the correct way around by cutting the leads to about the right length and trapping the ends under the screws in the terminal blocks as shown. I fold the leads of the diodes back a bit at the end to make them easier to trap properly under the terminal screws. Don`t tighten the screws too much at this stage as you may want...
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.....
