Re: Entropy

From a familiar story about an old axe. :lol:
When the pan is worn out, you change it, when the handles are worn out, you change them, but that still is the same wheelbarrow.

Re: Split Power Supply Load Balancing

The single phase Full wave Center tap ( The middle diagram in the three ) driving one load. The middle diagram of the three (FWCT) IS driving one load and I agree it will not produce DC in the core. But when the negative supply is added there are two loads - the second is not shown in that drawing....

Re: Split Power Supply Load Balancing

The single phase Full wave Center tap ( The middle diagram in the three ) driving one load. It makes no DC at the transformer. If it were, this widely used configuration would heat, the core saturate, eventually blow up. DC and spurious harmonics can occur only from a mismatch in the two rectifying ...

Re: Split Power Supply Load Balancing

Picking up this where I left off... The larger current draw from the positive supply caused the Texar Audio Prism's power transformer magnetics to saturate. The imbalance was due to a large amount LED current from the positive supply returning to ground. (An LM3914 was used so there was no choice.)...

Re: Gentle persuasion over time

I am missing right tools. I must invest in a long handle axe. I only have a small one, no good on that stump, it just bounces on it and that hurt my wrist. I need a sledge hammer and wedges. I need a big SDS drill for wood. I tried the ones I have for concrete, that is no good. Then I will be set to...

Re: Gentle persuasion over time

My large, cherry tree stump made some progress.
The fire over it regularly fed with logs is a slow process, but what is done, is done. Now, there is some depth below ground level.

I will call it, good enough and let it rod underground.

Re: Gentle persuasion over time

I enjoyed making bombs with chemicals I will not reveal here, that made so much trouble we had, the police all upset in the neighborhood. So we stopped this dangerous activity soon enough ( nobody got hurt ) when scared by a very big explosion, I could feel the shock wave at the back of my neck, run...

Re: Gentle persuasion over time

Extracting large stumps is a lot of hard work. There is much BS on internet and snake oil about this. Apart from the grinding machine and the good old way digging, sawing, prying...nothing really works. Such hard work, I have seen in Sweden a field where it was clear large stumps had been blasted wi...

Re: Entropy

I changed an electric cooking plate for a new one. A four burner plate, one of the four radiants was not working anymore. I repaired the old one. That was a wire cut at a spade connector. Now the heating works fine at the four burners, however the repaired one makes a noise the others don't. They cy...
