### theo jansen

Does anybody know the exact dimensions of theo jansen kinetic sculpture's legs? On a video theo jansen said that 11 different dimensions would work, but 1 was the best. Does anybody know the dimensions? I'm going to build a solar version just to impress people in this solar contest.

### Theo jansen mechanism

OK, I finally got hold of measurements for theo's strandbeest. these come directly from theo himself which means there accurate however it also means they're not in English. the numbers are there and they're easy to figure out, but it would be nice to know what the paragraph beside them says. so if any can read it, please post a translation. thanks

### Please explain Theo Jansen Mechanism?

We all have seen the Theo Jansen Machines and they are JUST AWESOME! I'm trying to build one. What is the the theory and mechanism behind Jansen's machines? Please explain.

### Motorized Gakken STRANDBEEST desktop model kit

Has anyone replaced (or plan to replace) the Gakken desktop strandbeest model kit's wind turbine with a toy DC motor and gear system?  If so, I would love to hear what specific motor and gear system was used and how you mounted everything on the model. It would take a motor with adequate torque to operate the twelve legs, a properly sized gear/gears to operate the model at a moderate speed  and some simple way to connect the motor/gear to the existing gear system.  I've seen hacks for K'nex, tinker toy, erector set, aduino, & custom builds but nothing added to the Gakken mini strandbeest kit except a hamster wheel.

### Walking robot - very cool, despite the headlights being in its knees...

This chap has home-built a Jansen-style walker. It's a well-made video as well.

### Anyone know anything about old (60's) guitar amps?

I picked up old a Jansen eight 25. It's in not bad condition, apart from a dodgy tube socket and a missing dial, all of which can be repaired easily. Anyway, I was looking on-line and could not find any data for it other than it's a early 60's amp. Seems to work great. the unit is about 2feet wide and 1.5 feet tall. Made in New Zealand. So I was wondering if anyone could provide me with more data on this, if it is worth anything. If it is not, then it would make a interesting teardown.

### I need to buy or fabricate a strong crankshaft for a strandbeest-like glass robot.

I'm making a walking robot out of glass based on Theo Jansen's strandbeest leg design. Fabricating the crankshaft has proven an odious challenge. I'm looking for a source where I can buy either a complete crankshaft to my specs or parts from which to fabricate my own. It needs to be about 30" long, with 6 crank arms (offset 120°, therefore 2 at each angle), throw on the crank to be 1". My original design was for a 1/2" diameter shaft, which is necessary if it's going to be glass, but if metal the shaft diameter could probably be smaller. The video here shows the crankshaft I made, but I don't  really trust it.http://instagram.com/p/x8xcPeyn-1/?modal=true  The prototype leg:  http://instagram.com/p/wewqr1yn6a/?modal=true
