Working LEGO Computer Keyboard


Today I am going to show you my latest creation
– this working computer keyboard built entirely,
uh, mostly out of LEGO bricks. Before I disconnect it from the computer to
show you how it’s built, I just wanted to show you the working light indicators. Num Lock, Scroll Lock, and Caps Lock. So, what exactly is going on here. We’ll start by looking at the insides. And here we see the original keyboard components.
I started out with a generic, run of the mill, computer keyboard, and this is what’s inside
of it. The sensor pad, circuit board, and of course
the computer cable. These are all sitting in a pretty basic LEGO
frame, it’s just built of basic plates and tiles. The biggest challenge with this project was
to interface the LEGO keys with the sensor pad, and in order to do that I built this
big grid of Technic axles, which floats above the sensor pad, and allows the keys to rest on it. I have a smaller scale model of the grid here,
just to show you how it works. It’s basically just a set of Technic axles
that are connected together and in this way each row and key can be precisely positioned
over the grid by sliding the connectors along the axles. Each key is made up of a couple of Technic
axles that slide through each of these Technic connectors, with some plates on top and then the printed
tiles representing the key. For the keyboard symbols I decided I wasn’t
going to use any custom printed tiles or stickers. I’m only using printed tiles that LEGO has
officially released over the years. As a result I had to get pretty creative with
some of the keys. The home key for example is a sloped roof
peak that you would put on the roof of a house. Scroll Lock is a printed tile of a scroll. Print Screen is a printed tile of fingerprints. A control panel for the CTRL key. A Windows computer screen for the Windows
key. I’m using the old M-Tron logo for the letter M. And for CAPS Lock I’m actually using a minifig
baseball cap with a lock tile. For the home keys I’m actually using one of
these one by two plates with a stud on it as well so you have that tactile feedback
where the home keys are, and the number five on the number pad. The keys can also be easily replaced, so if
LEGO ever comes out with more appropriate tiles for some of the keys I can just swap
them in quite easily. Well that’s about it, as you saw at the beginning
of the video it works just as you would expect. I haven’t encountered any problems with it yet. If you have any questions feel free to leave
a comment. Thanks for watching, keep on building and
We’ll see you next time.

  1. I like that keyboard. But it needs to have the appropriate “M”. And why did you put the M-tron for the letter “M”?

  2. Two things-
    1: I want this
    2: I'd likely have to engineer it for USB instead of PS/2, since my computer doesn't have PS/2 on it at all

  3. One day, I will make a remake of this, but fully black and with those glowing spider eyes from that hobbit set under the keys as glowing background light. Dang that would be awesome.

  4. So it's basically a run of the mill rubber dome with slider design, except the sliders,keycaps and keyboard frame are all made of LEGO bricks. Cool.

  5. This is some serious skill and creativity but it would be even cooler if you could find a way to make it with a mechanical board. Either way, it's still really cool and I'm sure it feels weird to type on.

  6. A recently found a lego camera I forgot about and although it would charge, the power button didn't work. I deconstructed a little bit of it by pulling pieces off with my teeth, but I just ended up ruining it. I wanted to see if there was any thing maybe blocking the power button, but no there wasn't. I'm so dumb.
