The white LEDs have different voltage and current requirements so they will need different resistors. So I`ll begin with a parts list: It`s the same idea as before, only the white LEDs are shaped differently because they have their own heatsink that they are mounted on. The two bullet lights are going to be smaller side lamps, while a large bullet headlight is going to be the main headlight.

Here it is opened up. I removed the light bulb but did not bother removing the battery case, as it was riveted in place and would have been very difficult to remove without damaging anything: I mounted the rear bullet lights using some of the premade mounting holes on the trike frame. Also visible are the wire crimps I used to connect up the whole trike. I am going to put black heat-shrink tubing over the crimps so they`re not quite so visible: Finally, all the wires (made of black 20 gauge lamp wire held in place by black zip ties) were run to a bag strapped behind the seat. The bag is just the right size to hold the electronics box: And there you go! The lights are bright as heck! I calculated the batteries as lasting around 2. 5 hours, but we haven`t tested the system to that limit yet, as we generally recharge the batteries after every ride anyway.
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.....
