First Rolling Ball Machine finished ...with quirks...

Well,it took me hours to design,build,redesign and trouble shoot,but the first RBM is finished.It doesn't run always smoothly since certain marbles seem to have their own ideas where to go.But the general idea works,this RBM is definitely one for the "it-ain't-pretty-but-it-works" category.

Rolling Ball Machines or Marble Machines

I've always had an interest in Rolling Ball Machines or Marble Machines but didn't quite come to the point of actually building one.But that has now changed,I'm in the process of making my first.
This one will be relatively simple,I'm using parts from a bicycle wheel and some other salvaged metal parts.
What won't be simple is the lift I'm building to bring the marbles to the top again and have everything working correctly.
While I'm working on my RBM,here is a video of some very beautifully made ones:

Yet another pummer.......

Part....number ?I don't know how often I've said that I would stop making Pummers for a while,but here is a new one.Made with a glass lamp shade,spring,test tube,ceramic fitting,brass fitting and wood.The battery is from an old mobile phone and the LED is a green one.

Yet Another Pummer.......

I'm getting quite a good supply of project housings,some ready bought and others made by myself.They are waiting for something to make them complete,and so can sit for some time on the shelf.
This one had not such a long wait:the housing is a tall rectangle made form Aluminium and wood,what made it complete was the glass pyramid I bought not too long ago.The name is not hard to guess then:The Pyramid Pummer,inside the glass is a very bright blue LED and the battery is a 3.6 V lithium-ion one from a mobile phone.
