The streamliner passenger car came into existence just before W. W. II as parts of dedicated passenger car and locomotive consists. They were designed to be lightweight to allow high speeds with a single rather small diesel engine. Eventually the railroads migrated them into regular trains based on their ride comfort and splashy looks. During the 40

`s and early 50`s you could occasionally find mixed consists of streamliners and heavyweights pulled by either steam or diesel or both in some places. A steam helper in front of an F7 ABBA set was not uncommon on the Cajon Pass. In later years, solid consists of streamliners could be found across the country. Aristo`s model of the streamliner car is based on a Budd prototype. The car is 30" long across the stock couplers and 27-1/2" long across the striker plates. This scales out to 66. 5` at 1/29 scale which means that this car is a little bit short. Unlike the standard heavyweights, these cars have no internal detail. There is a green tinted film covering the windows. The cars are lit and at night the effect is still quite good. There is an equipment box hanging under the car that looks suspiciously like the fuel tank on an FA. It even includes the cutout for the sound system on/off switch. It would appear that Aristo is recycling some tooling. The car is made from a single aluminum extrusion so that it really does look like polished metal because it is. The end caps are molded plastic and the color of the cap and doors attached to the caps do not match the car bodies precisely, but they are close. In the ATSF Warbonnet scheme, the engine color doesn`t match the cars, however in the prototype, they didn`t match either. The engines were painted steel and the cars were either stainless steel or polished aluminum. I have yet...
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.....
