I've been working on a different type of magbot pendulum the last few days.The idea being that part of the stand moves with the swinging of the pendulum.You could call it Newtons 3rd law of motion pendulum..or for every action there is an equal and opposite reaction.So the pendulum swings forward and the stand swings backward,then the pendulum swings backwards and the stand swings forward..etc.Nice idea,I thought,but it doesn't quite work that way.
Because when the pendulum swings forward and the stand swings backward,the pendulum drops down.It's that thing called gravity.....So I reckoned if I restricted the movement of the stand that would sort out this problem.But it didn't,it just stopped the movement of the pendulum.
I had a better result with weighing down the bottom of the stand,the movement of the pendulum is not as smooth though.Research continues.......

My latest pummer is one with a difference,but what else is new?With this one I wanted to be able to change the LED and capacitor(the one closest to the LED).So these can now easily plugged in,a sort of plug and pum so to speak.
Also the 47K and 100K resistors are exchanged for potmeters of the same value.I used one of those aluminium housings which are so useful for my projects.The end result is looking very retro I think.

The Solafloater is finished......but in the end it became an amphibious solaroller.Hopefully the the Miller solarengine works with a gear motor.I haven't been able to test it yet.After trying it with different other motors I found out that those were spinning too fast,making the driving belt slipping on the shaft.
