Even when people seem ignorant it is best to be nice to them, or your own ignorance may be revealed,
this is a place for all to enjoy, and benefit from.

Sulaiman, you are a very wise man, as your name suggests.

I've been engaging in internet discussion forums on various topics since the internet came to be for the general public.

An interesting phenomenon I've noticed over the years seems to hold true:

"The more harshly you ridicule someone else, the more likely you are to be wrong yourself."

Hi Bob, I haven't weighed any recently as my scales are kaput.
Still trying to fix them but am going to buy some more.
Did pretty well, the board was seriously corroded and had multiple bad SMD resistors but the dead part is that expensive strain gauge.
Can the e2prom be bad perhaps?

The transformers look like about 2-3g but quite heavy due to the Pb content.
I looked into making some from piezo igniters as these are also quite easy to find and making a hybrid toroidal piezotransformer is doable barely with sufficient Macgyvering.
(note: Z axis piezos are patented by Transoner but my modification may not be)

Two years after his first article, Chris Lee reports on another experiment on the EM Drive Link2

This one's been done by a German group. Magnetic interactions with power supply cables looks to be the favourite mechanism for generating the micro-Newton forces reported.
