Bricking up a page

When you create cool stuff, it just has to go viral. With over 4.5 million views and counting, this is a great example of technology garnering our interest and hence reach as we post, share and tweet about cool stuff like this. I think it’s time to get out the old Lego bricks and dig into my tech drawer. Thanks to my brother for making me aware of this. Check out this cool gear from horseattacks on YouTube.

 

“Lego felt tip 110″ printer connected to an Apple Mac. This is not mindstorms, I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a “wiring” board.

FAQ: Track name? “Christopher and Raphael just popper Shinichi Osawa distortion disco edit”

FAQ: How long did this take? Hard to say, maybe 3 weeks working evenings.

FAQ: You’re a student and this is a university project? I’m not a student, this is just a hobby project.

FAQ: Just a remake of the 1092a? No, I’d never seen the 1092a until now. However some of the parts came from a 8094 kit amongst others many years ago. It is made to my own design, but I acknolwedge influences and the great work of the official lego designers !

FAQ: Does this use mindstorms? Nope, wiring demo board + homemade analog electronics and sensors.

FAQ: DPI? Dots per inch? Approx 75 DPI

FAQ: PPM? Pages per minute? Not even 1! I sped things up a little in the video editing to keep it interesting to watch :)

FAQ: Helvetica? Yes of course, my respect to those who noticed :)

FAQ: Full color version/more colours? Originally I was going to do 3 colour version, but I had to simplify as only have 4 lego motors.

FAQ: Open source, schematics etc? Sorry this took a while:

FAQ: Wrote your own driver? Yes, uses standard Mac OS print mechanism.

FAQ: Are you using some sort of MCU demo board(the black pcb)? Yes. [1] http://wiring.org.co/hardware/

FAQ: re: Mac vs PC abuse? Video not meant as a Mac advert and I’m sorry if the Apple logo offends anyone. I just find them easier to use.

FAQ: Felt tip damage drying up? Yes this is a problem, but one felt tip usually lasts for quite a few pages.

FAQ: Felt tip auto-capping? Nope, sorry.

FAQ: Sensor info: Horizontal positioning using homemade shaft encoder (black/white rotating lego squares you see in the vid) with a SY-CR102 photo reflector from Maplins, (only £0.89 or $1.30). This is into a sampled analog input as I couldn’t get full enough saturation to trigger the ext interrupt pins. There are also push buttons built into lego bricks for left and right end stop detection.
