From the Dept. of Mysteries....

ok... three mysteries of late...

The first comes from a friend of mine.. Her father was a tinkerer and saved lots of random electronic things and I inherited them. Some were quite useful electronic tools and such, but others had no story with them. So here is mystery number one:

three bobbins.. common core.. one section meant to be rectified and filtered...

and this 127969AU number corresponds to??

mystery two:

last week my PC comes up with this:

nope, that is not my real desktop.... and, nope, I do not have any such program called "System Tool" on my computer. I knew enough to not click anywhere in the box, but even the Task Manager would not start... so I shut it down... After googling "System Tool virus" on an *Apple* computer, I found out it was definitely malware and that I could just delete the file after booting in safe mode. So the mystery here is just "Why do I even still have a PC??" and "Why does all of my simulation software run on PC's only?".... and finally, "Why do I pay McAfee??"....

and the final mystery for today:

how does one get a low frequency rumble on a simple LC power supply that is resistor loaded? this baby should be pure 120Hz.... I think I am about to learn something...



  1. The safest PC is one not connected to the internet. I actually disinfected three computers at work last month with the same gnarly system tool which also eluded our anti-virus which is kaspersky.

    Gotta love Mac :)

    Good luck

  2. Moral: Avoid McAfee and Kaspersky. Nod32 has never missed a virus in the wild...never...not even one.
