For larger builds there are the 'TrussFab' type designs using plastic pop bottles.

I wonder what other recycled household items have ended up in creative geometric structures.

Great idea for a maze. I had a maze for robots many years ago, probably in the 90's, for the mobile robot maze solving competitions that were popular at that time. Regretfully I never actually got around to making a working maze solving mobile robot. I had some none working ones, but none that actually found paths.

Excellent project Doug. Have just assembled a Ikea bed that used flat panels in grooves in wood to stiffen up an assembly. So routed wood or bolted together extrusion is another approach.

Hello Sir;

I am trying to build a 3D levitation system in which you can suspend anything irrespective of outter body position. But the main problem I have been facing is the huge currents consumption.

Do you have idea how to control current consumption (with series resistance) and coils heating problem.

Ive always wondered how complicated it would be to create a levitation system. It would be fun to see the internals on that. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-27cf2c4f-f7f8-4fa9-a6bc-e62ebca86d7c/5074.contentimage_5F00_1.png:16:16]

Hi Doug,

A nice mixture of cute and technical. I am concerned about Sparky's brain implant though.

Hi Doug,

Happy New Year to you as well - great project [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-27cf2c4f-f7f8-4fa9-a6bc-e62ebca86d7c/contentimage_5F00_1.png:16:16]

Do you need any feedback with a system like that (where I assume you are repelling the permanent magnet in the item's base by an electromagnet from underneath) to stop it getting flung off sideways ?

Cute Doug! When we should expect this chick grows? I want to see how you solve the problem to make eggs [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-27cf2c4f-f7f8-4fa9-a6bc-e62ebca86d7c/contentimage_5F00_2516.png:16:16]

A fun project. What sensor did you use to detect the coins?
