New energy sources for Pummers....

Just fun I try sometimes alternatives for batteries or solar cells in my pummers.So far I tried using  windpower  but that didn't create enough voltage to charge the batteries.Although I do know that you can use it,I just haven't build a wind turbine which creates enough energy(yet).
Today I took a step back in time and made use of one of the earliest battery forms:copper electrode,zinc electrode and a salt water solution.Later I added some vinegar for good measure.
All this goodness created a staggering 0.270 Volts!But a few of these cells in series should be able to charge a capacitor....We'll see......

New Pummer

This new Pummer is the first thing to come out of my workshop after what seemed to be a long time to me.But in all fairness,I had this one already sitting on the shelf.The only thing what was lacking was the circuit.Normally I don't make dual Pummers,this one is only the second one.
Again Wilf Rigters improved Pummer circuit was used with some changes:C1 and C2 are now 2.2 uF and the 47K resistor is now 33K.
In this photo the solar cell is not attached yet.

A quick update.....

As I haven't blogged in awhile due to being away on holiday and sort of taking it easy,here's a quick update.At the moment I'm very interested in urban exploring as written in the last blog and looking for new locations.
As for new projects in the making:more Pummers(of course),robots and generally  do more metalworking.
