                                 I'm the retired engineer guy who sometimes has a few items of electronic  parts for sale, it's just an ending hobby, and I'm clearing it out, really!   

I  am currently selling major amounts of my semiconductor and IC inventory to active buyers, and would encourage you to seek a quote on those parts you would like to have for yourself!

The prices typically need S&H added, but please make an offer... Email:  Ron Black Email

Family references:

My sister Marilyn Black Phemister passed away Jan 19th 2012 after a long bout with pneumonia which was complicated due to her muscular dystrophy.
I have assembled a scrapbook of pictures to help friends and family to remember her life.

    Political lesson for today..... History Lesson, not only opinion:

MEMORIAL DAY May 30, 2016:      Google "Thomas Jefferson vs. the Muslim World."     Do it , it is really important!
    Here's some more political opinion I wish to share (June 20, 2014):

Governors of 35 states have filed suit against the Federal Government for imposing unlawful burdens upon them. It only takes 38 (of the 50) States to convene a Constitutional Convention.

This will take less than thirty seconds to read. If you agree, please pass it on.    This is an idea that we should address:

For too long we have been too complacent about the workings of Congress. Their latest stunt is to exempt themselves from the Healthcare Reform that they passed ... in all of its forms. Somehow, that doesn't seem logical.
We do not have an elite ruling class that is above the law.
I truly don't care if they are Democrat, Republican, Independent or whatever. The self-serving must stop.

This is one proposal that really should be passed around and talked about now.

Proposed 28th Amendment to the United States Constitution: "Congress shall make no law that applies to the citizens of the United States that does not apply equally to the Senators, President of the United States, their employees, Representatives of Congress; and, Congress shall make no law that applies to the Senators and/or Representatives that does not apply equally to the citizens of the United States"
