Electronics > Beginners
It's not easy being a beginner........

That's a much better usable viewable image in the 1st post. :-+
I loaded the 2M 4160pix image.
Adjusted the brightness a bit, and the contrast a bit more.
Resized it to 700pix wide, which easily fits a browser's width without any resizing, and looked fine at 100%.
There's only about 230 unique colours in it, so reduced the colour to 8-bit grey scale.
Saved it at normal .jpg compression, which gave the only 10kB.

Bingo!!! I was wondering when someone would notice the "absolute" statement about digital high!!!!

I was reading Electronics for Dummies last night and thought I would have a browse in the glossary. Now I was willing to accept everything I read as correct and to soak up the lingo (as I know next to nothing about this subject at the moment), UNTILL I read the following which I KNOW to be false.
(Attachment Link)
I find this concerning! When trying to learn the technicalities of a new subject being mislead in such a way can make you believe that you'll never get the hang of something and give up when for instance a formula you learned off by heart was incorrect thus never allowing you to achieve the correct answer.
In this instance, imagine telling an engineering student that a hexagon was "squarish". Ok, so now a hexagon has what? Four sides, four corners. I could maybe understand, but only just, if the shape being described was a parallelogram or a rhombus.
Up to this point if the book had stated that a transistor was batteryish I would have read on without knowledge of the nonsense I had been served, until I had learned better later on and maybe wasted valuable time.
What else am I expected to cross reference before I can know that the information I am reading is correct?
OK. Thanks. Rant over....

Yeah!
Good to see your BS meter is working well! :bullshit:
The glossary statement was "double dumb"!
"Hex" in the electronics sense, is more likely to refer to "Hexadecimal" or sometimes just "six" as in things like "Hex Inverters"
(I aways felt the latter device sounds more like something you would need for self defence if you upset a Witch!) ;D
The bit about "high" digital voltage levels is BS, too---- the range of voltages which are read as "ones" or "zeroes" are different for the various types of technogy used to manufacture digital ICs, & normally are included in the device "spec sheet", but a "high" is never just "any value above zero"!
Edit:- Oops! In my eagerness to get to my "witch" joke, Ialso misled you. :-[
I have added the part in italics to clarify things!
