Lego Printer == Awesome Answered

The last Lego forum thread I started went down a storm so when I saw this Lego printer online at BoingBoing today I HAD to post it too.

YouTube user Horseattack posted this video a few days ago of a printer that he made using Lego to move a felt tip pen across the page. He doesn't give much detail about how it was made or any instructions on how to do it, but the video is pure awesome.

Here's what he had to say about it in the video description:
"Lego felt tip 110" printer connected to an Apple Mac. This is not a kit you can buy and does not use mindstorms. I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a "wiring" board.


lol that person that gets rocked backwards and forwards must be well peed off!!!

That is just so... COOL!

Dang it, I just moved my entire LEGO collection to the backs of various cabinets and shelves, not planning on getting them back out until I had to entertain a small child...now there's this and the LEGO FlexPicker that make me want to drag them back out...I HAVE TOO MANY PROJECTS TO PLAY WITH LEGOS!!!

Aww heck, I never put mine away. Still have a spaceship sitting on my desk :D

Well, duh, the completed models are on display...I'm talking about the boxes and boxes of pieces. :P

The Instructables team needs to hire this guy ASAP!! My son is 36 and has never put his Legos away, they are around all his various sitting/leisure areas, just like I have rocks in every area I use!

Fuu, you are the new awesome. Go ninja!

That would be praise indeed if it were my project :( I just found it online and posted it here for everyone to gawp at :p

OMG! That is so cool!

That is awesome! But it can't print small text can it? Keep the Lego ones coming.

Very nice!  Though technically, shouldn't it be called a "plotter"?

Hackaday argue the same point. "We feel this is a printer and not a plotter because the stylus moves on just one plane while the paper feeds past it but that’s open for debate as well."

:-)  Okay, fine.  We have a massive HP plotter at work (can handle 1m x 4m sheets!) which works exactly the same way.

I'd say printer as well, since it rasterises graphics and only draws horizontal lines... isn't it a one-dot dot matrix?

Interesting side note- this guy did it first (by 25 years?), and also built an actual plotter that would draw vector graphics, and hand-write text at 5cps!

That guy's a badass, I always read his woodworking site, woodgears.ca. There's some awesome stuff there.

Neat!  Way back when, Lego produced a Technic Control Center that allowed you to build and program, among other things, a CNC plotter.  You couldn't connect it to a computer, though!

Coolest forum topic ever! I want one :)

No, not a topic, a printer. :)

:-D  Yeah, but you made it just too easy...

Ah, what would we do without the extremely sarcastic minds of instructables?

I don't know.  Why don't you tell us?


This is on the BBC's Tech Brief as well, along with a rather amusing video of Nigerian 419 spammers performing the Dead Parrot sketch...

How did you get your  main  pic?

Is he talking about your avatar or the title pic for this thread?

Oh, I assumed "main pic" meant that picture of the printer.

@ TSC, if you mean my avatar, click here.

And if you meant the printer picture, I cropped it from the youtube video.

OH MY GOD !!!! Thats the coolest thing I've seen in at least 3 months.

"an error occurred" - bah.
I'll try later


On the video?  I've been getting that with the embeds for a couple of weeks now.  In my case, if I click in the video window, it takes me to YouTube directly, where the video plays just fine.  Don't know why, and other people don't have that success.
