Garage door contraption (yet another)

[gohan]

@barduino nice project, but may I ask you why you choose the distance sensor instead of a reed switch or micro switch?

[dbemowsk]

Though I do think it is an interesting concept, but I would pose the same question as @gohan. Why not a reed or micro switch. Those seem like much cheaper options.

Maybe bescause he had the parts around?

Or this way you can check if it's moving up or down as it's fixed on the rail and senses the door moving to or fro ?
Edit: he explains in the text itself.

[barduino]

Yeah, I wanted to know the exact position of the door, if it was opening or closing etc.

Anyway I'll gladly share the 3D files for the Easy board

0_1490732701131_Base.zip

This is the SketchUp file with the base, rail, lid and enclosure for the sonic.

0_1490732828480_GarageDoorMonitor.zip

And this one the base and lid for the monitor.

The Easy boards I have are v8 and the mounting holes are so small that I couldn't create a support that wouldn't break, so I decided to make some rail/slide system.

Also because I don't solder the Arduino or radio directly to the board, the lid becomes very tall. But its easy to adjust in the 3D files.

If you prefer STL files, I'll upload them

Cheers

@dbemowsk, I'm very interested in your decora style wall plate, maybe we can compare notes

[dbemowsk]

@barduino Last night I created another decora plate that has 2 bigger switches. I will probably be pushing that one up to my thingiverse account tonight. I have to make the board for it yet, but I think this one will be a bit easier since I only have 4 switches and 2 LEDs to deal with instead of 8 and 4 with the other one.

I also have a project I did with my easy newbie boards where I made an enclosure for my bathroom temp/humidity sensor. Here is the link:
https://forum.mysensors.org/topic/6485/hdc1080-battery-operated-temp-humidity-sensor-with-wall-box
You mentioned that you couldn't create a support that wouldn't break. If you look at the temp/humidity enclosure I just have 4 mounting tabs inside the box. I am using 2mm x 5mm screws to secure it. These are the screws I bought to use on my decora switches. They work great. the tabs are big enough where there is no real chance that they would break. I could possibly get some longer screws because if I screw these in and take them out too much the hole kind of gets stripped. That shouldn't be much of a problem now that I have the enclosure perfected, I shouldn't have a need to remove screws much.

[barduino]

@dbemowsk , the problem is that I lost my screws... (portuguese joke meaning lost my marbles or gone crazy)

Anyway, do you create the threads for the screws in the plastic? or do you use self-threading...

When I do my supports I make them snap-on, like a little wider in the base and then a bit of plastic that goes through the board holes. If the holes are too thin the snap-on bit breaks.

cheers

@barduino I get it, I just have holes that I use self tapping screws in like this style:

I just bought some 2mm x 5mm ones from ebay. As long as you don't torque them in real tight, they hold good. So to hold a circuit board in a box, it is more than enough.

@barduino

I had a test setup that also had a sensor looking down so I could 'see' if my car was parked in the garage or not.... if distance < 1m == car parked.

My garage door opener is directly above my car when its parked.

[barduino]

@koen01

I'm going for a similar next step.

The cars must be parked in a very specific position relative to the side wall and the garage door, or otherwise it's almost impossible to move around the garage.

Something like this Hek project.

Cheers
