After having its engine and other mechanical parts restored to its optimum condition, the next thing I had in mind is to add aesthetic lighting. I went to a local electronics store and found these 12V DC Operated LED Strip. These are perfect for what I had in mind. Luckily, I remembered the voltage doubler circuit introduced to us in our Electroni

cs class during my college years. The voltage doubler circuit introduced to us at that time needs an AC input. Though its not the right circuit for my problem but it gave me a reason to look for a voltage doubler circuit that works with DC input. The search led me to this very cool site full of interesting useful circuits, the. Out from which I got this circuit. This site did not only post the circuit schematics but also a detailed description of how the circuit works. Since some of the components shown in the circuit schematics is not locally available, I had to replace them with similar components that are available here in my place. The schematics of the modified circuit is shown in figure below. I tested this circuit using a 5V DC input. The output voltage measured, using my analog multimeter, is 8V. Theoretically, it should have been 10V but due to the diode and transistor P-N junction threshold voltages, the output voltage is minimized to 8V. Tested this circuit again using the battery of my motorcycle and with the LED Strips connected to the output port. As can be observed, the LED Strip lights up brightly. The power supply part is done. The next part is the strobe controller which I will be calling as Alitaptap. Alitaptap is the Filipino term for firefly. I have decided to make one out of the NE555 Timer in Astable Multivibrator (with diode) Configuration. The circuit schematics is shown below. This circuit is the...
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.....
