stripped down Rube Goldberg Machine – Video

because i got the video yesterday from tim devine (thanks for recording it):

and for all the (mac owning) Incredible Machine fans (and especially for tim) – i uploaded a little game from 1994 to my server:

robobug from outer space

hello eveyone!

my project was a combination between some crazy electronics and some weird looking metal skin, supposed to be  a robobug from outer space. in fact, he can respond to anything around him by going forwards and backwards, this way overcoming any obstacle, and he can also use his tail to create strange sounds, like a real buggy bug should do.basically i used a toy car and and made it go boom a lot of times.here is the proof:

also some nice pics from the presentation

in the end, i would like to thank time’s up team for this amazing workshop that allowed me to do some hardcore circuits and ,of course, to blow things up!

The Blue Danube Waves


The romantic feeling of making a small portable mechanical moving lake, powered by water seemed very tempting… well… and quite easy on a first glimpse. But coming little by little into details revealed a picture bit different from what I expected.
My initial plan was to make couple of layers of waves, fishes and boats. They all had to be connected with wheels and powered by running water (on the principle of the water mill). As a result I succeeded with only one layer by offsetting the center of the wooden wheels and mounting the waves structure on them.

Short list of the important things, that I learned from the workshop:

1. Sometimes things are lot more complicated from what you have expected
2. The details really matter
3. Making things with your hands makes you very happy

Thank you Tim and Marc for the great experience and all the knowledge that you shared with us! Respect!
Big thanks to all the participants for the help and the spirit!

Collection of mechanical models

In reference to Hennings picturesque 2d mechanical-assembly – but of cause for everyone interested in the beauty of mechanical motion – I´ll post a link to a big online collection of kinetic models to get lost within…

sini’s work on progress

So the days are passing by and at the end of today my work will be maybe at the point about where I thought it’d be by the end of the 1st day… So if I manage to build the loop where the belt is turning as I walk on my stilts it’s great. But I’ve got something to develop after the workshop also, which is great.  Estimating times I haven’t learned yet but a lot of other things like thinking of how to make parts for things that are supposed to move on a much more detailed way than before, or how it feels when the sandpaper machine grabs the edge of your piece of metal when you are not focused. It’s been a great experience and luckily one more day to go. I’m running late now, see you!

The Sorcerer’s Apprentice’s lucky day

Why lucky?! Because the machine is not alive.
But this does not mean the work was unsuccessful. The trigger to save and release the energy of the snail-spring would actually work (in theory :). Due to the crudeness of the construction the whole mechanics jammed easily (which means a chance of jamming of 100%).
Additionally I was surprised that I did not have to scrap my whole construction and start all over again with a new blueprint anytime during the workshop. The construction just grew and added up and still remained “functional”.

Below are several photos to show the stage of construction i reached:
The mechanism in its early stage
Almost all of the parts, but unassembled
Detail of the mechanism
If not handled with care this can become very painful

I took the mechanism home for now, to analyse it a bit more. I’m planing to build not only the mechanism but the outer shell – which I couldn’t get even near to think about during the workshop – with the help of a 3D printer.
I will probably scrap the mechanism afterwards, unless I can find a generous buyer who’s interested in crude 2D mechanics to hang up his/her wall 😉

btw: I uploaded some pictures of the workshop to an album. Go have a look. Unfortunately I couldn’t capture all the projects because my card space was running out very quickly.
