The above table is useful to determine the capabilities of the MOSFETs for the various versions. However, the connectors I have used on the LED3X `c` series is not rated for such high currents on a continuous basis. The connector is technically rated for 7 amps continuous. I find that 10 amps is not to excessive if done intermittently and much hig

her currents if the the pulses are short. An experiment I have done was to drive a 12V automotive door window motor. This motor draws about 4 amps at 13. 8V. I raised the voltage to 44V with a pulse width of about 1 second out of a cycle time of 18 seconds. The peak current into the motor is 55 amps @ 1/2 second! Everything remained reasonably cool. Cool huh! The LED3X series Tracker PC boards uses through hole parts. These components are easier to assemble than the surface mount parts on the previous LED3 tracker. The assembly should be done in the specific order outlined to minimize the risk of damage to the circuits in case there are solder shorts or misplaced components. The components in this circuit are susceptible to damage through static discharges. Use normal static discharge prevention techniques such as a grounded workbench, soldering iron, and personal grounding wrist straps. Also the large mounting hole is connected to the negative power terminal and should be the first point touched when handling the circuit until the connector is installed which can then be the first thing touched. When I say to "Tack Solder" this means to solder one lead of a component on the top side of the board. I have arranged all the components so one easily accusable lead is always on the end closest to the mounting hole. The components are small and light and one can`t turn the board over unless tack soldered because they will fall...
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.....
