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.

poetic aesthetic machine

most of all i really appreciate to Tim and Mark and people who participate in this workshop,

it was super nice times and atmosphere to me ,

actually, at first i would like to hide some technical things , i would like to left just really simple movement at machine, and i hoped people concentrate beautiful mood in machine not technical things , that’s why i used candle, and bicycle wheel (i think these are very beautiful,*)


anyway, at last, i made water switch which can control of electricity status, it was very nice experiment , because i realized even very simple technic which i learned at elementary school can be nice interactive source.

(the water switch principle _ i installed long green pipe and i blocked both side of pipe for making water not leaked and put saltwater in it , and i install this pipe on the wood board which can have angle by small metal pipe which installed under the wood board as 90degree turn from wood board. when people step on this wood board this board can change the angle and water  flow according to low direction and this water touch +and – electronic and then this electricity change the switch that can change  motor’s direction)

and at first i want to make my own candles ( shape of skull, macbook, building, woman arm, animal and ect, which n can make people feel creepy)  for make them rotate according to wheel’s movement but i couldn’t resolve it in proper time.

but this wheel which i installed was quite fastly moved than i thought,

and then make me scare when this start move, even my friend described it as  beast, i was quite shocked

the unwilling to deliver the message, swimming bottle

Continuing from the chindogu point, I tried to come up with a project/object that would resist it’s usefulness. Water and windmill were already part of the Time’s up scenery, some bottle were lying around also, so with these ingredients and a little help from my friends I concluded to built the “ unwilling to deliver the message swimming bottle”.

The project tried to serve it’s purpose in two ways:
a) it should find the wind direction, get energy from it and try to swim against it.
b) try to float against the current. This second part was soon abandoned and I concentrated my work on the first one.

In the process of building it up, the boat soon grew to a double bottle catamaran, since the floating issues (e.g. balancing the whole thing , keeping the total weight of the construction smaller or equal to that of the bottle) were easier to approach like this. Finding the right materials to avoid friction on the motion transfer weals was on of the issues we were faced with. Balancing the different parts and keeping the bottle together were also points to work out.

The boat did manage to float eventually, eventhough the messages we put in did push it deeper to water already. The propeller seems to require a good amount of wind to start spinning, which might already be enough to take the whole thing apart in open-sea circumstances. And the paddle-hands aren’t probably big enough to pull to the opposite direction.

Nonetheless I am planning to let it free during summer time in the Aegean sea after securing a bit the insulation of the bottles. Hopefully it will fail it’s purpose and reach somebody!

Theo Jansen re-make update

Hello!
I brought my little animal home today and it suffered some ‘mild’ modifications on the bus so I had to remove some of the damaged pieces of the sustaining structure. But I added the other pair of legs so now it almost looks like the real thing. Slowly but surely, I will also add the propeller and build a stronger structure to hold the legs.
I would like to thank the Time’s Up team once more for this brilliant workshop and the wonderful time I’ve spent learning, experimenting, failing, drilling, failing again and laughing at myself but in the end having a great time! Thank you!
