FYI: Marking up image, PDF data sheet or schematic on IPad

I, as many of you, use an ipad to hold device data sheets, schematics, images etc. that are in PDF format.
I have been using PDF EXPERT for some time and highly recommend it. See examples.
You can search, bookmark, draw, highlight, underling, type text, etc...
Highly recommend it if you add documentation to images, or PDFs.
I have no connection with the company.

Thanks Rob.
Yes there are several PDF programs on the Apple Apps site.
It is nice to be able to annotate the pages of your documents (PDFs) with these programs.
I downloaded all the date sheets of the all I.C.s I normally use onto the iPad.
Threw all my mildewed data books (about 150) out in the re-cycle.
I now just print the odd page from a data sheet when I need a hardcopy, but usually just use the iPad screen.
The Annotations get printed also.

What's going to happen when a physical virus starts eating all are silicon? =(

What's going to happen when a physical virus starts eating all are silicon?

We will have bigger problems than a few datasheets...

The whole earth is made of silicon for a large part ( SiO2 )

For the chemically inclined, silicon is the element (Si), while SiO2 is more correctly called silica (or silicon dioxide).

Oxidizing silicon will release energy, so from a thermodynamic point of view, the silicon-bug could live from it (The biologists are probably not going to agree)

So there could have been such a bug in the past given the large amounts of SiO2 :wink:

I think I'll stick to the principle of Ockham's Joint:

If you have to possible explanations, go for the one that has the highest entertainment value

Absolutely! I have a direct descendent of those silicon bugs as my avatar!
