DIY gate remote opener for under 50$

Показать описание
I decided to make a system for as cheap as possible and still as good as possible. I wanted it to be reliable, good looking and cheap.
Price for the parts is roughly around 30$.
I used cheap Arduino clones of eBay, Arduino modules with relays, a reciver module with remote, some LED's and a finished warning light enclosure. None of those cost more the 5$ per piece.

Everything else was made by me.

Hope you will get a similar idea and share you work and enjoy the video!

Here are some links for buying the parts:

Great job!
The only thing I would do differently, I would use a motorbike sprocket and a motorbike chain for longevity. Just cut the chain open, lay it straight and weld on the bottom where your rail is. With some grease that'll last longer than the aluminium rail.
Thanks for the video!

Wow! Great job Sir. I even like the home made hand break (sheet metal bender ).

Bravo! Ingenuity, patience, skill(s). Not to toot my own horn BUT, I once used a scooping implement to remove and relocate a section of terraforma to create what is called a "ditch".

I install gate motors professionally. Other than some safety protection you did a great job. I would also put in some position logic so you know where the gate position is, and an easy override should you loose power, slip clutch. Great job.

Great job.
But...I wonder if it wasn't better to weld a chain along instead of making 100 holes?

Hi, I like your project so much. I have some questions for you:
- Is the motor self-locking? (can you open/close it easily by hand?)
- why did you use a 4channel relay module? 2ch would be enough, wouldn't it?
- how much does the gate weitgh?

Thanks in advance for your answers

Instead of using a rail, why didn't you use the bike chain. Bolt to gate at one end, and a tensioning thread at other end. We use them in Australia for commercial gates as you don't need to be so accurate about the rail meting the sprocket. The motor has two idle sprockets lower then the drive, chain goes under idle, up over drive then under second idle. As you said, you needed the springs as the gate lifted up. You don't with chains, and a lot of the gates are not perfectly straight, and a lot of the rails o he ground are not perfectly level. Chain doesn't care. Nice work. Keep it up.

You did an awesome job on the gte opener. That is amazing. I have never built RF remote control board as you did for this. Is there anyway you could email me the instructions on how to assemble the board you made. KEEP UP THE AWESOME WORK MAN

Good for you. Good construction ... but in case you want to open it with your hands? How is the gear disengaged?

You had me at $50.
(But you lost me at welding)

3Yr check-in, how does it hold up? I'm looking into building my own.

Great job, I prefer a one button control board with limit set. Is that 2 limit swiths works well now?

Great Job. by any chance do you happen to have the schematics for this? would love to see a diagram. also how did you come up with the code? Im a beginner in this and looking to do some projects

Exactly what I need except I need to build everything including the gate and rail and footing for the rail to sit on, or pay large amount for someone eles to do
