This project was on my list for a while. The main reason was that the winch on the Jeep is permanently connected to the battery. So every nut job in a parking lot could just stick a paper clip into the winch remote and play with the winch, or worse, shorten it out. I wanted to disconnect power when the winch is not in use so no one can play with i

t. The second reason is that, should the solenoid in the winch get suck somehow, the winch pull can be stopped by killing power, sorta like an Emergency Off button. I also wanted to control the winch from inside the cab. Most of the time when you winch other people out, you have to stay on the brakes anyway (unless you tied the Jeep up to, say, a tree or such). So it`s just more convenient to have controls inside. The winch power disconnect was simple. All you need is a relay/solenoid big enough to handle the load. What peak Amperage the winch draws depends on the winch brand and type as well as the pull. More load/strain takes more power. Some winches use more power than others. I think my Superwinch was listed as having a 350 A max current draw at 9000 lbs (55 A at 0 lbs load). 350 A is a low draw compared to other winches, which was one reason I chose that winch. Other winches might be more around 450 A at full load. Since a short in the winch (motor melting or whatever) would mean shortening out the battery, and perhaps cause the power cable to catch fire, I thought it would be a good idea to add a fuse as well. After all, most everything else in the Jeep is fused, so the winch should be as well. Again, I chose 500 A for the fuse (although 450 A would have been sufficient for my winch. But I`d rather not blow it out due to overload during a pull, and be left without a winch when I need it). Winch power will be...
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.....
