Does anyone know where I can buy one of these cores preferabely in UK but
failing that, US?

Masterplaster, you can buy it from a German Webshop as well:

Something nice to play with during the winter holidays

Group,

My tests with the new transformer did not charge the battery.

I guess my switch is not fast enough the get the desired result.
When I say fast, I mean the rising and falling edges of the pulse.

I have tested at least 100 different SW timings and pulse durations.
The closest I got was a near unity result when the battery did not
charge but did not discharge either. (Or it discharged so slowly that
I could not see it on my meters.)

My attempt to get this work was a failure, but that does not mean it
could work for others.

Alex.

Are there any other replicators on this board ?
The PDF made by Bob Boyce is really amazing und it fits exactly in the operation of Steven Mark's TPU.

What pdf?
