The latest pummer

As mentioned before it's another one of those record player pummers.This one with a large glass encased solar cell and a yellowish LED.This will probably be my last pummer for awhile,but I have said that before.......The next project will be a solarfloater(?)or basically a boat powered by a Miller solarengine,with paddle wheels.

Finishing and starting magbots and pummers


I've finished two magbot pendulums:the Circle one,which has a big pendulum bob and doesn't swing that freely(I might have to change that one)and the wooden balls one,now with two solar cells.
I've also started to build another record player pummer,soon I'll be running out of room to put all these pummers........

The circle magbot pummer


This is still a work in progress,but is almost finished.Obviously the pendulum bob itself is missing in the picture.And some minor adjustments to the electronic circuit have to be done.

It's been awhile.....

but I just came back from a two weeks holiday in The USA.As usual I brought some parts back which I ordered from various suppliers.For example wire-glue and E6000,which are not easily available here(The Netherlands),some rainbow LEDS and some magnetic Hall effect sensors(hold a magnet near the sensor LED goes on,LED goes off when you hold the other side of the magnet near it again).
An update on the magbot pendulum which I was working on:I found out that I need a bigger solar cell to make two circuits work,or use two solar cells.
I also started making a new magbot pendulum.More about that later.
