Every innovations starts from a simple day to day life problem like you watching IPL in TV and suddenly the current shuts off, fortunately you will find another way to watch the match via mobile network. Similarly, I too had faced a problem of frequent.... -
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.... -
A solar water heating pump controller is a key component in most solar water heating systems (DIY or otherwise). The controller is there to turn the pump on when the fluid in the solar panel is hotter than the water in the hot water tank (or swimming pool),.... -
A solar charger for an iPod is no more difficult than making our Solar battery charger. Built in iPod batteries are 3. 7 Volts with the capacity (measured in mAh) dependent on the type of iPod - e. g. 1, 200mAh for a 2nd Gen, 850mAh for a 3rd Gen, 500mAh for.... -

To obtain the power supply graphs on the previous page, I didn`t stand outside for two days straight measuring the power sources with a voltmeter. Instead, the circuit itself is able to independently monitor the power sources with the addition of a few.... -
The SCC2 is a solar charge controller, its function is to regulate the power flowing from a photovoltaic panel into a rechargeable battery. It features easy setup with one potentiometer for the float voltage adjustment, an equalize function for periodic.... -
There are 2 kinds of solar automatic tracking controllers. One is Schmitt trigger light control composed of a light sensor and a Schmitt trigger or monostable trigger. The second one is usingtwo light sensors and two comparators to form two light-control.... -
This solar birdhouse light is an economical circuit of a mini solar lighting system circuit is presented here. At the heart of the circuit is a mini 6V/2W solar panel. Here, this solar panel is used to charge a 4V/800mAh rechargeable battery through a charge.... -
This Outdoor LED Solar Garden Lights project is a hobby circuit of an automatic garden light using a LDR and 6V/5W solar panel. During day time, the internal rechargeable 6 Volt SLA battery receives charging current from the connected solar panel through.... -
Voltage regulator is connected across solar-cell away as shown to prevent damage to storage battery by overcharging. Series diode prevents array from discharging battery during hours of darkness. Regulator does not draw power from battery, except for very.... -
This is the most simple and affordable solar battery charger that the hobbyist can make. It has a few drawbacks over other similar controls, but offers numerous advantages. It is intended for charging lead-acid batteries, but may also be used for charging.... -
The simple circuit below regulates the voltage from a 6v solar panel to a fixed +5v. That voltage can be fed to any cell phone or USB connected portable device, to charge its battery. The circuit uses a Reg113-5 voltage regulator from Texas Instruments. The.... -
This is the main building block of the home automation system. My goal here was to design one circuit board that could be customized for different functions by selectively populating the board, adding daughter boards, and changing the software. Currently,.... -
A power inverter converts DC power or direct current to standard AC power or alternating current. The following schematic shows a 12V power inverter Circuit Diagram... -
The giant (by radio control standards) servos above are shown adjacent to a Nokia 3310 mobile phone to give an idea of the scale. The arms are 12cm long - perfect for lifting a bank of solar panels (wing). Our local Model Aerodrome in Seaside Road,.... -
The analog interface is a very simple analog to digital converter which accepts the analog video output of the RF/IF board and puts it into a form that can be read by a PC Games port. The joystick input of the games port essentially converts a resistance in.... -
Whatever past project these were used in obviously required three cells to be wired in parallel with a rather large (4700 uF) capacitor on a perf board. There were 13 of these board assemblies, for a total of 39 solar cells and 13 capacitors (not to mention.... -
One of the coolest parts of working on the Yahoo Purple Pedals project was figuring out how we could get the bikes as far off the grid as possible. Once we decided on using the N95 as the brain for the bikes, we had to figure out how much juice it takes to....

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.....
