How To Make a LEGO Vacuum

How To Make a LEGO Vacuum


In this video, we’re going to be showing
you how to take this Lego brick container, and transform it into
a vacuum that can suck up, and then store all of
your Lego brick pieces. [Captions by Judy V. at Y Translator]
[Music] [Music] To get started, we’re going to
need some kind of plastic box, a vacuum cleaner and
some spare vacuum hose. I happen to have one
of these actual Lego boxes that’s shaped like a giant Lego brick, but you don’t have to use one of these. If you just have a clear plastic
shoe box size container, that will work just fine. We’re also going to need an exacto knife, a glue gun, some type of mesh cloth or fabric, and all of the ingredients that we
use to make our proto-putty, that’s type 1 silicone, some food coloring and some corn starch. Here’s what we’ve got in mind. We’ll cut two holes into the lid, one for the hose going in, and one for the hose going out. A proto-putty seal around the whole lid
will prevent any air from leaking, and a mesh filter on one side
will prevent any Lego pieces from accidentally getting
sucked up into the vacuum cleaner. First, we need to take the lid of
our container and add some holes. If you’re using these
nice Lego containers, I like to put them right here on these bumps because it just keeps the aesthetic. If you’re using you container
with a more flat lid, you can just cut right into
the flat surface. We’re going to want one hole on one side
where our vacuum cleaner hose will go in, and another hole on the other side
where our additional hose will come out. Now, I’m in a workshop
and here we have a shop vacuum. But if you want to just do this
at home with your home vacuum, that will work just fine as long as
you have a hose that can be pulled out. One quick note about
using a home vacuum, if you have the type of vacuum that has
turning bristles and you take the hose out, you do want to make
sure that those bristles aren’t still rotating in
contact with the carpet because after a couple of minutes, the friction can begin to melt
or burn some types of carpet. So, if you are doing
his as a home vacuum, you may want take your vacuum cleaner and tip it on its back so that the bristles
aren’t going to burn anything. Now, we want to make a hole in one side
that’s just the same size as this adapter, and a hole on the other side
that’s the size of our vacuum hose. I picked this vacuum hose up at a store that just specializes in all
sorts of different types of hose. It was pretty convenient. If you don’t have one of those near you,
there are a few other options. There are some kinds of pool and
drainage hose that are about the same size, and this is a 1 and 1/4 inch diameter. Or you might be able to find an
old vacuum that doesn’t work anymore, and take the hose off of there, or if you have a vacuum repair shop, they might have some broken vacuums
and be able to sell you one of the hoses. Let’s take our hose, place it right where
we want our hole to be, and then trace around it
with a permanent marker. [Music] And let’s do the same thing
with our other hose. These hoses are very similar
in size but not quite identical. If you happen to have a hole saw that is exactly the same size
as one of your hose connections, You can probably use that and
it should work just fine. Both of my hose connections ended
up being not quite the same size as any of the hole saws, so we’re just going to use
an exacto knife suspect. [Music] I suspect I’m still going to need
a little additional trimming before this fits quite right. Yeah, it’s still just a little tight. I just need to trim down
the plastic a bit more. [Music] There we go. Our hose now fits in
and it is nice and snug. It holds itself in place. You can see that the lid
is just really well attached. But we can pop it out when we need to. That’s one cut.
Now, let’s cut the other side. [Music] Now, on this box specifically,
the corners have these support pieces that I think helped keep the box
in shape and help it stay on the lid. While those may increase the structural
integrity and be a good thing most of time, they can kind of get in the way for us, so what we need to do is trim away
some of these little plastic tabs. [Music] We now have our hose intake, and our hose outtake? Is that right? Hose in and hose out. So, what we need to do is make it so
this lid fits perfectly snugly onto our box. As it is, we can attach
the lid and it may stay on, but there’s a lot
of space around the sides. Air is going to be able to get in
through all of the gaps, and we don’t want that. We want all of the suction
to come out of the front of the hose. So what we need to do
is make a proto-putty seal that goes all the way around, so when we have the vacuum turned on, all of a suction is coming
from one spot only. [Music] Also, this particular container
has two small holes at the bottom, and we want to plug those up, and we’ll just use a little bit
of our proto-putty for that as well. [Music] All right, our proto-putty is starting
to set but it’s not there yet. You can see we’ve still got
lots of squishiness to it, and that’s exactly what we want. While it’s still squishy, we need to take our lid
and press it down over the box so it forms a nice tight seal. And the goal is not to make it
so the lid can’t come on and off because of course we do still
want to be able to remove it. But the goal is so that
when there is suction in the box, it just pulls itself nice and closed instead of having lots
of air rush in all of the gaps. [Music] One more thing that you can do. If you cut your holes and you find that the
hose is a little more loose than you’d like, you can use some extra proto-putty
to make a seal that goes around the hole to make sure your hose
connection is nice and snug. Depending on how well
you cut your holes, you may need to do this on
one side, both sides or neither side. Now that we’ve got everything formed, it’s time to just let our proto-putty cure
for a few minutes until it’s nice and rigid. Our protoputty is nice and cured. So now we can remove our hose, and we can remove the whole lid. [Music] If you’ve made the proto-putty correctly
with all the cornstarch mixed in, it shouldn’t stick too much. It should just be able to slide on and off
while holding itself nicely in place. One of the nicest things about the
proto-putty that we use for the seal is that it’s designed not
to stick to things too much by adding all of that corn starch. That’s really nice because it
means we’re able to fit it on the lid, and then take the lid off and on. But one of the downsides is
that it is possible that your seal will just be kind of loose on your box. If you want to make it
a little bit more permanent, you can take a bead of the caulking without
any food coloring or cornstarch in it, and that should do a pretty good
job of bonding the silicone seal to the plastic of the box. This stuff is sticky. It’s only not sticky because
we added so much cornstarch. Now we don’t want any little
Lego pieces to get sucked up into the actual vacuum cleaner. So what we want to do
is add a filter onto one side. I’ve got a little piece of screen mesh. You could also use any
sort of cloth with large mesh, like a tool
or some kind of netting. This is just what I have available
so this is what I’m going to use. This little flange seems
like it will get in the way, so let’s just try and trim
that off with our exacto knife. Now, I’ve got a hot
glue gun and our mesh, let’s just cut this to size
and then glue it right over that hole. It should still let air flow
through it really nicely. It’s not going to slow down
the vacuum power at all, but it’s just going to make sure
that none of our Lego pieces end up in our vacuum cleaner. [Music] That’s pretty hard to see
but it did draw on it. [Music] That’ll do it. We have a mesh
covered hole in one side, and a non-mesh covered
hole on the other side. We should be able to pop this lid on, attach our vacuum hoses, and start sucking up Lego
directly into our Lego storage box . [Music] Box full of Lego pieces. Very cool. That worked great. And you can see a little bit
of fuzz did get sucked up and pulled up against our little filter here. So that may be something that is
worth cleaning every once in a while. Really small dust should probably
still get pulled right through that filter. The bigger dust will just get caught up
against it but that worked great. It even pulled up some
of these longer skinny pieces. They didn’t like to go very well, but when
you suck them up with other pieces. It all sort of traveled through the hose, even some pieces that
I thought seems kind of large, like this little window frame piece, It does fit in the tube but not super easily. But it still managed
to travel up through there… Quite nicely. Well, this works great, and I did want to do one thing just
to show it off even a little bit more. I have a second Lego box
that I’ve modified by adding a clear window
onto the front of it. Now, we should be able
to see the Lego pieces after they’ve traveled
through the vacuum tube, land in our box. And we can see how well that works. [Music] That’s awesome. Just flies in there all over the place. It’s pretty neat. Now, like I said it’s not necessary to put
the clear window on the side of your box. That’s just something that lets us see
what’s going on as Lego flies in there. And I think it looks pretty cool. Overall though, I would
just go with the normal box. No window added. Because you know,
that’s going to work just as well, and save you some time and effort. Guys, this has been awesome
but the fun doesn’t have to end. This little box up at the top will
transport you directly to our last video, and you should check that out. The box at the bottom
will show you what YouTube thinks you need to do watching now, and this bomb here in the middle
will subscribe you to the channel, so you never miss out on a video. Don’t forget to ring that bell
and we will see you in the next one. Talk to you then.

  1. I was thinking you could put a latch where the window was and make sure it's filled up with the Proto putty

  2. lol in my school we had to invent sonething and i had an idea similar to that…( i have siblings and every mess they make i am for some reason responsible for it so i wanted to make that.)

  3. I just used a sheet and would do legos on the sheet. then I'd pick up the sheet and dump em into the box when done.

  4. To be honest why would you spend so much time and energy on this it’s really not that hard to pick them up with your hands

  5. I think you could have done it without the corn starch. Just put a bead of caulk on the edge of the box then use a mold release on the lid. Place the lid on the caulk and a day or two later, after caulk has somewhat setup, the the lid comes off and now you have a silicon gasket.

  6. I made a LEGO sorter for my youngest, who has a ton (many are from my youth). I was able to make a sorter on my 3D printer, which is just a sequence of square holes ranging from 2cm/side to 5cm/side. For as simple as it is, it works well. This idea and that one could be fairly easy to combine to create a LEGO vacuum/sorter combo.

  7. you should try to make an axe from just a stick and a rock in the wild with vines to hold it together. I am making one and it is really fun

  8. As a diy dad. I’m building this next weekend. I find more legos with my feet then my kids ever do “cleaning up”

  9. hello why don`t you use a hot exacto knive or a solder iron with a knive on t on plastic or Styrofoam then it gos way quicker

  10. Can't believe I've just watched a ten minute video just to watch some Lego get vacuumed up at the end.. Gotta love TKOR!!
