BattMan II is a computer controlled battery manager, intended for typical rechargeable batteries used by R/C and electronics hobbyists, as well as various consumer product batteries. BattMan II has the following capabilities: Works with Nickel-Cadmium (NiCd), Nickel-Metal-Hydride (NiMH), Lithium-Ion (Li-Ion), Lithium-Polymer (LiPo), Lithium-Nano-P

hosphate (LiNP), and Lead-Acid (Pb-Acid) batteries of 1. 2 to 14. 7 Volts. Requires sufficient memory to comfortably run Windows, a few megabytes of free hard disk space, and 800G—600 or higher resolution display. If you want to modify the software, you`ll also need Borland C+ Builder 5 or newer. BattMan II is a fairly complex project, and this article assumes that you have some electronic project building experience. If you`re reasonably careful in construction and follow the testing and calibration instructions closely, you should have no problems getting it to work. Your success with this project will benefit from an understanding of how it works, so please read the next section carefully before you plug in the soldering iron. If you don`t want to build this project but need a device like this for your consumer electronics batteries, you might consider the La Crosse Technology BC-1000 AlphaPower Battery Charger or Maha Powerex MH-C9000 WizardOne Charger-Analyzer. This performs many of the same functions as BattMan II, but only for AA and AAA NiCd or NiMH cells (up to four at a time). The La Crosse charger also comes with adapters to let you use AAs in devices requiring C or D sized cells. The power supply I used is a commercial off-the-shelf model that can supply 18 Volts at 2. 2 Amps. I purchased mine at a surplus store. Any similar power supply will do, so long as it produces 18 to 20 Volts, and enough current for...
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.....
