How To Keep Your Radio On When You Start Your Car
Our car radio has the annoying habit of forgetting what part of a CD it was playing when you turn it off. On long drives this is a real drag; I`ll leave an audio book playing for my family in the car while I gas up, and when I turn the key from Accessory to Start, the radio turns off and back on again. I built a cheap circuit that keeps the radio
Touch-Controlled iPod Nano Sound System for Car
How do you make a 1950 Studebaker even cooler? By installing an iPod Nano in the dashboard, of course! The folks over at MAYA Design hacked their way to a touch-controlled sound system with this project they`ve dubbed the ""Nano-Baker"" (or ""Stude-iPod"") using a pair of Apple ear buds, a USB cable, a voltage regulator and a set of speakers....

Cheap Motorcycle Alarm
Cheap motorcycle alarm circuit. During parking, hidden switch S1 is normally open and will not permit triggering of MOSFET T1. But when somebody starts the motorcycle by using ignition switch S2, MOSFET T2 triggers through diode D1 and resistor R5. Relay RL1 (12V, 2C/O) energises to switch on the alarm (designed close to IC1) as well as to disconn
Easy Build Motorcycle Alarm
The following circuit is a simple, cheap and easy build motorcycle alarm. The circuit just required 2 transistors to drive the relay the the relay act as a switch to activate the buzzer. Any number of normally-open switches may possibly be applied. Fit the mercury switches to ensure that they close when the steering is moved or when the bike is li
Switched Bike Light
Do you have a bicycle. why don`t try to build this circuit. . Powered using battery 3-6V. This circuit will help the bicycle driver in the night and help other people to know your presence. Switched ON Bike Lamp circuit diagram: Component part list: R1 = Photo resistor (any type) R2 = 22K 1/2W Trimmer Cermet. This is the circuit diagram of autom
Car Speed Alarm Schematic
When we are driving sometimes we do not know the speed of our car, especially when we are in the course of the highway so nice and straight, if the cars speed is too fast or faster than anyone could lead to accidents that do not want to happen. The circuit then requires the Car Speed Alarm is to alert the driver who did not notice the speed becaus
Make this Fancy LED Tail Ring Light Circuit for your Car
The following article describes a fancy LED sequencing/diverging ring type light which can be used as a tail brake light in cars. The circuit idea was requested by one of the avid readers of this blog, Mr. Bobby. lets learn more. Could this circuit be adapted to create a round tail light that lights rings in sequence from the center out as the bra

Ultrasonic distance finder circuit
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 measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
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 find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
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 circuit comes as a solution to this problem. Depending on humidity of the pot at...
Simple deep searching metal detector circuit
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 circuit of this metal detector, it is possible to detect a metal coin in depth of 90 to...
Sub-Harmonic Bass Converter for Electric Guitars
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, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
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 calibration of the rope. This arrangement still exists in some yachts. The big...
100W HiFi Audio Amplifier Circuit
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 supply must be symmetrical so that no electrolytic capacitors are needed at the outlet....
Plant-Pot Water Level Indicator Circuit
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. The circuit of the device is shown in Figure 2. The water detection is made from the bottom...
Analogue Sound Preasure dB-Meter Circuit
The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from 100Hz to about 13KHz and depend on the age and health of the individual. We for our measurements and to have a good accuracy we will get the limits of 20Hz to 20KHz. A sound to be heard does...
