Printing a repair part for my guitar

March 19, 2012 in 3d printing by Rob

I’ve got an old Finnish “Landola” guitar. It’s a 20-year-old piece and has much history to it. The nut broke down some weeks ago. Today I printed a new one. Guitar hack’d!

Guitar loves 3d Printer!

Download the nut from thingiverse http://www.thingiverse.com/thing:19451

Dishwasher Hack

March 14, 2012 in 3d printing, household hack by Rob

An import plastic piece in my friends 2-year-old dishwasher had broken apart and it couldn’t function without it. It’s the lock mechanism that keeps the dishwashers door closed. My friend wanted to have it repaired but it turned out that there’s no repair shops that have these parts and you can’t order them from anywhere. He heard about my 3d printer and came to me with the dishwasher. We made 3 different prototypes of the plastic piece (all working ones). Took about two hours to make them. The last prototype we made much more robust and more simplistic than the original part.

My friend Jukka with the hacked dishwasher

Look at the dumb design of the original piece!

The original part on the left and the printed part on the right!

Printing the third prototype

Perfect match!


If you need the same hack to this dishwasher Matsui MF654EWN I can send you a part or if you know someone with a 3d printer you can download the part from Thingiverse http://www.thingiverse.com/thing:19175

The Second Mind-Blow Thursday

March 9, 2012 in Uncategorized by Rob

Yesterday we had our second Mind-Blow Thursday in the Lab. It was me, Olli, Sebastian & Fred. Later Hector & Cribs also joined. Here’s what we discussed and what blew our minds..


Vertical food-growing gardens that use a dirt-free technique called hydroponics. At first we were amazed about it but then we started thinking. The dirt-technique has been around for millions of years and nature has developed it for all those years. Can we really out-clever nature on this one? With hydroponics you use mineral nutrients in the water and of course you need to buy these! When you plant in the soil you only need to make sure you have a good soil and for that you just need to have a good composting system. You don’t need to buy the nutrients! I guess hydroponics work good with todays consumer society but if you really think ecologically it’s not that good.

Everything is a Remix

A mind-blowing documentary about remixing. You have to watch this at http://www.everythingisaremix.info/. It lead to interesting discussions and to this video

What makes you get up in the morning? Think about Free Software & Open Source movement for example, giving tools, knowledge and power to the people. That’s a very good reason to rise up in the morning! I think you can get unlimited amount of energy from that source! ;)

Painting with Light

Fred started asking me questions about how cameras work. I gave him a short lesson and we somehow ended up taking these amazing pictures. It’s cool what you can do with a dark room, flashlight and a camera. If you want to try this for yourself use a very long shutter speed and a very small opening on your lens. We used 30 seconds and F22. Place the person or the object somewhere in the dark room, put your camera on a stand, take a picture and start light painting with the flashlight while the shutter is open.

W00t! Join us on next weeks Mind-Blow Thursday!

Making games with Python and Pygame!

February 27, 2012 in Uncategorized by Rob

I got this crazy idea to make a point and click adventure game. Inspired by the good old Monkey Island games back in the 90′s. I haven’t really come across any good adventure games these days anyways! I think game developers nowadays try to make the story to complicated or with too many side stories just to make the game last longer.

Since I’ve done a lot of short films and story telling I got this idea to make the cut scenes with real movie footage. It’s something I haven’t seen before either! The game environment would be pictures of real location and the characters would be real actors animated in a stop motion kind of way.

So I’ve been fooling around with Python and the game engine Pygame. It’s really a sweet coding language. You get things done very fast… if you know how to code… :) now, I haven’t been coding any games since the 90′s and back then I only coded with Qbasic and Basic. Somehow though I’ve learnt to do things in Python really fast! Got the basic functions figured out already + I got a mpeg playing really nicely in the engine.

OMG! It’s Guybrush Threepwood! :)

OMG! A RepRap 3d Printer in the Lab!

February 27, 2012 in Uncategorized by Rob

W00t!! Yes, we have a 3D printer. It’s a self-replicated bot called the RepRap Prusa Mendel. It has already printed parts for the next printer (gotta love bots making babies)

You can read all about it on http://reprap.org
