The main reason to go to the trouble and expense of running trains on battery power is to avoid cleaning or even wiring the track. The issues of track cleaning really can be a big deal. Adding radio control to a battery power system adds the capability of command control, a highly desirable feature. In some environments, any kind of track power is

flatly impractical due to a number of conditions. In other environments, track power works quite well and is certainly less expensive than implementing battery power. If track power works and the added flexibility of command control is desired, then consider adding Digital Command Control (DCC) to an existing track powered system. Both battery R/C and DCC allow command control at something like the same total expense depending on the number of locomotives converted. DCC tends to be more costly up front and less costly incrementally. If a large number of locos are converted, DCC becomes less expensive than battery power. If you go that far, the money probably doesn`t mean that much to you anyway. If track power works in your current setup, DCC will work too for all but the smallest locos and it will add all the advantages of command control in a flexible and expandable fashion. Walk around radio control with DCC is also highly effective if not a little costly up front. Due to the limited number of power pickups on small locos, they will require fairly clean track to run and might best be converted to battery power anyway. A battery powered loco will run fine along with DCC locos. MU operation with battery and DCC in the same consist would have the same problems as MU control of two independently controlled battery powered locos. There are few economies of scale for fully self contained battery power. If you are just...
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.....
