Tripod Spinner

Yesterday during my lunch break I quickly made a Geomag bridge. Nothing really fancy, more just to check out how to build the connecting bits at the angles. The result was a bridge that still spanned 37", so not too shabby. I could've made it another few inches longer, but didn't feel like messing around with it much. I'll wait until I have more rods before I'll do that.

Still, I figured I'd put up a picture of it:

After lunch, there were network problems and a new Windows security patch had to be installed. So between compilations, reboots and the like, I used RaM's latest creation as inspiration to build a tripod spinner.

It turned out really well, though I want to see if I can make the arches a little bigger today. We'll see how well it'll work out. Anyway, I really like the result so I wanted to show it off here:

Hope you like it too :).

Pyramids

At the end of last week, I made a little pyramid after Miller broke the 360 paneled sphere just so that there'd be something on my desk. It's quite cute and looks like this:

Then Miller came along and modified it into this:

Note the Sphinx of which he was quite proud. It made for a cute little decoration.

In the meantime, I made another little pyramid on Friday. Nothing really special, but it's cute nonetheless:

That's it for now :).

The classic 360 bar sphere, paneled

Two days ago I quickly put together a regular 360 bar sphere with Geomag:

A coworker suggested adding panels to the sphere, and he spent some time putting the panels in. The result was actually quite pleasing to the eye:

Since I always like the pictures showing detail on the inside that I've seen, I've tried to make one of those too even though my camera isn't too good at it. I still like the result though:

I'm going to need more bars and panels if I am to go up a size sphere...

Supermag bridge (final length)

The final length of my Supermag bridge was an unsupported span of exactly 42 inches (106.7cm). It collapsed again when a coworker hit one of the supports with the wheels of a chair. While I could have fixed the pieces and rebuilt the bridge, I decided it was time to clean up instead.

Eventually I'll try and beat my own record again, but for now I'm done.

It looked cool while it lasted :).

The Supermag Bridge (continued...)

Today I increased the size of the bridge so that there was an unsupported span of 37.5".

When I tried to further increase the size by 2 more rod lengths, the bridge collapsed. I'll have to rebuild it in order to try and beat my new record. It shouldn't be too hard...

Supermag bridge

And, by request, here's today's lunch break: An attempt to break my own personal record for the longest unsupported span of a bridge. With the bridge I posted late last year, it was about 19.5", and I had been unable to make anything longer.

Today I tried a different concept:



It seemed stable enough, so I added a few pieces to it:



And while it needs support on both sides (I really need to bring in some weights I guess), this bridge has an unsupported span of over 24", and there's room for expansion still. I'll try some more tomorrow hopefully.

Modifications to the Arch and spinner

I made some changes to the arch and spinner from the previous entry. It now looks like this:

It's a lot of fun having three spinners going at once, since their rotation affects the rotation of the others so their relative speeds are constantly changing.

 

Interesting Arch with spinner

Inspired by a post from eddwo in the Geomag forums, I thought I'd try my hand at building the same arch:

Geomag Arch with spinner

It turned out quite nice, but was trickier to build than I had thought. The top center especially is tricky. The top is a hexagon, but it is not 100% flat. I tried putting a dome on the top of it but can't make the magnets fit. The corner pieces are not entirely perfectly matched either, and when I tried to add a few magnets for internal support, the next pentagon wouldn't fit properly.

I tried a couple of different center pieces as well but couldn't make anything fit quite right. The base for the legs is different from the original post, and my spinner is different, but other than that it's eddwo's design.

Switching to Geomag

After seeing some impressive constructions made with Geomag panels, and my own inability to create an unsupported bridge even a third of the lenght I've seen with Geomag, I have decided to start concentrating on buying more Geomag.

Of course, I'm keeping my Supermag too, as I like both a lot.

I found a good sale on Geomag, and bought up the stock that they had at my local Toys 'R Us: Geomag panels 60 for $9.99. (13 yellow rods, 12 balls, 35 panels).

I'm currently waiting for an online store to restock the Geomag collection 1450 so I can buy one of those... I should have enough panels now :).
