I am rewiring my entire house after a major malfunction of two antique knob and tube circuits. I`m up against a challenge with some outdoor lights. Here`s the situation: I have a detached garage. It has a porch light over the service door, and it works on a pair of three way switches located in the garage and in my kitchen. The porch light over th

e kitchen door also works with this garage light - they are both controlled by the same 3 way switches. I`m a really big fan of this setup, and I hope to save it. The garage is powered by an underground 10-3 romex cable connected to a 2 pole 30 amp breaker in my brand new 200 amp main service panel in my basement. It goes to an old QO service panel in the garage that has no main breaker and no ground bar. There is also a 12-3 romex cable going to the garage to make the three way switches between the two buildings function. Neither cable has a ground wire. Both cables are buried under my blacktop driveway and not in conduit, so they are so hard to replace that let`s just assume it`s impossible. I know I need to replace the load center in my garage with a new, grounded unit. Remember, I`m rewiring a whole, enormous old house built in 1878, so getting the lights back on is first priority - I`ll get to the garage when the house is done. My question concerns the 3 way circuit controlling those two porch lights. It seems like it shouldn`t work with only 3 conductors travelling between the switches and lights on both ends, but somebody did all kinds of janky stuff with the old knob and tube wiring to make it work (It wasn`t me!). I`m thinking about doing something that maybe isn`t quite as janky as that, but I need to know whether it`s safe. There is no building inspector where I live, so just go by National Codes and personal...
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.....
