No problems turning it on, but after I unload the input (no input current), the triac doesn`t turn off. The load is standard RS-232 voltages (+/- 12V), speed 56k. You mentioned you have already tried using an OptoTriac, so the schematic of how you connected it, power source (e. g. voltage, whether it shares the same ground as the modem/PC) etc, is the kind of thing that would come in handy. The clearer the question

the easier it is to give an accurate answer. Oli Glaser Oct 29 `11 at 2:47 If you continue asking questions in this manner people will get tired of trying to help you. |If you can say "I have no problems turning it on, but after I unload the input (no input current), the triac doesn`t turn off. " - you MUST have a circuit in mind and must have tried it or simulated it. To then just say "I have no schematics yet" (if you wrote that) is missing the point. | IF you tried using a TRIAC and IF it did not work then you will be able to provide a circuit diagram somehow, and should. If you won`t do people the courtesy of doing that you`ll rapidly lose people willing to help. Russell McMahon Oct 29 `11 at 10:14
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.....
