8/16/2023 0 Comments Homemade automatic gate openerYou keep a garage door opener on your visor (or wherever) to open/close the gates. In my neck of the woods here in Texas, the gates leading into the ranches have solar units. With many more to work on but none open themselves. On a farm is, I would have to say the gates. Have some gates I would like to use this on.ĭear Homesteadma, if someone was to ask what the most important item Resets itself, or if this was just a hollywood gimmick. Movie again very carefully, but if I remember right, there is aĬounterweight, cable, pully system and fly wheel. Does anyone know of where or how I can do this pretty reliably? I watched the movie "Babe" with the kids, (again) and remembered the way the farmer had his gate "rigged" to close automatically. gate across our driveway, without having to jump in and out of the van all the time. I'm looking for a way to open/close a 12 ft. In order to execute a remote controlled open, close action of the gate, S1 and S2 could be replaced with momentary relay contacts, and the relays operated through the receiver unit of the remote control.Īny standard 400 MHz RF, 2-relay type remote control modules could be used for the stated remote open, close control of the gate.Non-electric Gate opener plans? non-electric Gate opener plans? : LUSENET : Countryside : One Thread The gate maintains this position until S1 is pressed yet again for initiating the opening action of the gate.thus the open/close operation of the gate is simply implemented by actuating S1 and S2 switches manually. in the closed position, when it presses S3, cutting off power to the motor and yet again disabling the motor. While in this mode the motor gets its power from S3, but only until it reaches its earlier destination, ie. This immediately flips the motor polarity causing the motor to rotate in the opposite direction and enables the gate to reverse back to its closing position. This position can be maintained infinitely, until S2 is pressed, which breaks the T1/T2 latch, and deactivates the DPDT relay forcing its contacts to move across the N/C points. The gate now halts and comes to a stand still. This also releases S3 in the process.Īs soon as the gate reaches the end limit or the end destination, and opening up fully, it presses S4 cutting off the supply to the motor. The motor now begins running through the supply via the S4 and the DPDT relay N/O contact supply in the set direction, enabling the gate to operate with an opening action. T1 and T2 instantly latches, actuating the DPDT relay in the N/O positions. With the above situation, pressing S1 initiates the following course of actions: The DPDT relay contacts are at the N/C points. The latch circuit switched OFF, and so is the DPDT relay. S4 in released position and therefore contacts closed and switched ON. S3 in depressed position by the gate and therefore in the cut-off mode. S3 and S4 are fixed across the end travel points of the gate mechanism, such that the gate pushes these OFF each time it reaches the end destinations, and releases while it moves away from the destination or while the gate is in the course of its travel.Īssuming the gate to be in the closed position initially, we can expect the following scenario: Operational Steps Transistor T1, T2 along with the associated parts form a reliable latch circuit, S1 and S2 are ordinary push-to-ON switches, where S1 is rigged as the "set" button, and S2 as the reset button, which work for opening and closing the connected respectively. The above Switch is to be used for S3, S4
