Good day to all. In this article, the author of the channel “Mr SunY” will demonstrate to us how to assemble a tool similar to a laser level from a laser pointer. And so who are interested in reading on.

Materials: wooden beam.

Cardboard sleeve from stretch film or paper towels. Can be replaced with PVC pipe.

Electric motor from a toy car.

Battery "Krona"

Contacts to her.

This type of switch.

A small mirror.

A plastic tube from a candy or from something else, the main thing is that its inner diameter matches the diameter of the motor axis.

Laser pointer.

Tripod for the camera.

And a nut of the right size.

Materials:
Nail file for metal.
Marker.
Roulette.
Drill.
Drill.
Hammer.
Soldering iron.
Tin and rosin.
Glue gun.
And the rod is silicone.

The author sawed off a piece of 200 mm from a bar.




Then paste a cardboard sleeve on one side.



After the motor is glued to the end of the beam.


Like this.

Next, establish contacts on the crown.

The author will divide the red wire into two parts, it will go through the switch.

Then the red motive from the battery will be screwed to one of the contacts of the switch, and the author will screw the second piece of the red wire to the second contact of the switch and the motor.

After sticking the battery to the bottom of the bar.


Next to stick a switch.

After soldering the wires.

Next, the author marks the center on the mirror.


And glue the straw from the candy.



After installing the mirror on the axis of the motor.

Verification

Further in this place the author will make a hole.


And install the nut.


Then install in the nut, the mounting plate of the tripod.



A laser pointer in a cardboard sleeve.


Here homemade and ready.


The author will install the finished homemade product on a tripod.

And start the test.

Result.





You can adjust not only the height and angle, but also you can change the position from horizontal to vertical.



And that’s all for me. Thank you all and see you soon!

What kind of pin?
In the center of the slot, vertically upwards, like a barn lock, and in a bit there is an axial blind hole, I think you met, you just forgot. While I did not have a bit with holes in the end, I simply broke these pins. smile

I just triangularly (well, not quite triangularly, but close to that) sharpened an ordinary flat screwdriver
The main thing here is to correctly break the pin sticking out in the center of the slot! smile

When there were no screwdrivers yet, and the screws were already there, I just triangularly (well, not quite triangularly, but close to that) sharpened the usual flat screwdriver.

I remember these times. Screws and screws for the "cross" appeared, and there were no screwdrivers anywhere. I remember the moment when (for some reason?) The whole evening saw in the "vise" screws with a hacksaw a slot with a flat screwdriver ... There were a lot of screws ...

had to engraver grind a screwdriver out of a thick nail
Happy man
I turned my first Phillips screwdriver out of some steel axis with a file! For a long time it was, not like an engraver, it was impossible to buy a screwdriver! smile

Place a round glass rod in the path of the beam.

I looked around ... Well, even it’s somehow strange ... Nowhere do I have round glass bars lying around here! smiles
True, and motors too ... And mirrors ...)))
So, in any case - it’s better to draw with a pencil, if there is not even a cheap Chinese "laser level" ...)))

A happy person - they lasted so long.))). Now I’ve already gone and bought it ... And like ten years ago I tried to disassemble the iron, so in general I had to grind a screwdriver out of a thick nail with an engraver ...))))

It is not clear why no one translated the fasteners of the cameras to the metric format. After all, fotiks have long been not English.

I think for several reasons - 1). Standard. Photos are not only released in "metric" countries ... 2) "It already exists" - the transition will imply confusion with the choice of a "new or old" tripod. 3). For aluminum and plastic, an inch thread with a larger pitch is preferable ...

How the hell?))))
Kreatif! Custom pad! Arichinality of the decision ...
A complete set for the delight of sofa masters who love DIY-life hacks ...
The video didn’t look, but I won’t be surprised if there is some kind of action unfolding there under the music, reminiscent of the progress of apartment renovation in the “Housing Question”)))) .... (This is, for example, when a shelf is applied to the wall the first time in level and in the right place, the shooting plan changes right there, and the beautiful, clean screwdriver chuck immediately fastens it with a shiny screw at low speeds.) And right away (softly) soft toys are laid out on it ... And that's it - on the right ones places and hard! ))))

And how the level on a good tripod will help to establish strictly vertically (horizontally) the axis of the engine glued with thermal nozzles
I agree with you, if I urgently needed to bungle something like that on my knee, I would try to use some rectangular template when gluing! smile

And yes, a “nut of a suitable size” will not work here.

Here I came across a new (for me) slot on the screw head. The household kettle had to be taken apart. Three-blade slot type 3V. How many invented them all sorts of Hewlett-Packard. Screwdrivers do not stock up scratch

In general, the resulting crap can come in handy ...
Here they write about the fact that the level, they say, is not exposed, and so on ... That's right. This is not a level, but a "laser pattern." For example, once upon a time, when making repairs in an apartment from scratch, I used a cheap (for a couple of dollars) Chinese "laser level", which was also essentially not a level - a curve! If you set the bubble, the line is not at all in level. But he helped me well - I draw a meter line on the wall at the usual level, and then put the "laser line" on it. This is faster than fending off the horizontal to the full length of the wall. And already by laying the laser tile, I fasten the profile of the ceiling, pour the screed)))))
Only now, to do such crap for the sake of such use .... To put it mildly, not camillo!))))
That’s for the sake of "DiAiVai-govnosamodelki" in the YouTube video - yes! That she is perfect!))))

By the way, yes ...))))
I repent with cruelty and without censorship ...))))
After reading about the "inch", I remembered that ... that I wrote nonsense in general.)))) It turns out that I did the adapter "father-father" !!!)))). And then he needs a "dad-mom"
... I did make such an adapter and "stumbled", which I already forgot about ... I cut the internal metric "six", but the tripod bolt did not go into it. That's why I screwed the trim of the stud there (I didn’t find a suitable length then, but I had to do it "here and now" - the work was on. And I always have a lot of different studs in stock))). He screwed a piece of a strip with two holes, "sticking out to the side", and fixed it on a tripod with a brass nut (with an "inch"), which he dug in a box with the rest of the plumbing.
.. Apparently, this completion was “completely forgotten” precisely because I thought up and did the idea of ​​the adapter in advance, and when I came to work on my construction site and tried it, I decided everything else on the spot and quickly ... And from what it was ... And there are so many of these "decisions on quick and on the knee" that they are not remembered ...))))
I repent !!!

And how level on good a tripod will help to establish strictly vertically (horizontally) the axis of the engine glued with thermo nozzles to the end, it is not known at what angle the sawn bar is

Made an adapter for the laser level
I also made an adapter, remember the Soviet photo - a clamp, with an adjustable ball bearing, it seems that the FED-2 was called? To spice jewelry vise to it, I had to sharpen the adapter from an inch thread to a metric
Two types of threads are widely used on cameras, camcorders, tripods and other equipment: 3/8 ″ -16, 1/4 ″ -20 Inch thread 3/8 ″ -16 (three eighths of an inch, sixteen threads per inch) is used to attach a heavy light, photo and video equipment, mounting tripod heads on tripods and monopods.

M6 - not standard?
I, apparently, are not standard, the thread pitch is larger, aluminum is still, but, of course, all mine photo - video equipment sits down on everything photo - tripods. A standard M6 nut on photo - tripod does not sit down! smile

what should she go to?
A tripod is attached to the screw, and there the thread is not standard.

M6 - not standard?
At least in my one “Canon” and two “Nikonahs” - M6. And they all "sit down" on a tripod purchased in China.
Tomorrow I’ll specially look ... Maybe I’m mistaken, and there - not the M6 ​​...
Although ... I made an adapter for the laser level for this tripod. And in level - M14. I cut a piece of the fourteenth hairpin, drilled a blind hole with the “five” on the axis, cut M6, screwed a piece of the hairpin “six” ... Everything went well ...

You can’t call Ugovina because it is not connected with the level of the earth in any way.
A good tripod has its own level.

What for? It was only necessary to hang a glass rod before the pointer and it would have turned out the same. A plus would be a real level, and not just a green stripe on the wall that cannot be called a new name because it is not connected with the ground level.

Mr SunY will show us how to assemble a laser-like instrument from a laser pointer. And so who are interested in reading on.
Why are there so many mistakes even in the introduction? Where should the commas be? So. Iraq, and the cat. xaxa

There is a mechanism in the laser level, thanks to which the line is always strictly horizontal. You can set the device as crooked as you like, and the line will still be horizontal. This same mechanism to add, and everything will be ok.

And instead of a mechanical sweep, a test tube with water is better. If it is suspended vertically (exactly beyond the center of the cork), a horizontal line will turn out automatically.

Hello! I have one question - where did the author get a nut of the right size?

laser level instrument
I would say "remotely reminiscent of." I’m just interested in the service life of this “tool”, slabbed “on the knees” of “shit and sticks,” how long will the mirror adhered by thermo nozzles last? There is no balancing, no adjustment (by the way, why is the level set here?), No strength, in general, a one-time self-made “throw-out”.
