Title: [INDEX] Metrology section quick guide
Post by: TiN on December 14, 2016, 04:47:51 am
Having 7 pages of forums threads in Metrology section is already enough to get less frequently discussions be buried deep down. So I think small index would help newcomers and volt-nuts to navigate to interesting bits more easily.

Before you scream "use dat search button", I'd like to clarify, that being a daily reader of Metrology section since it was created from Day 0, yes, I use search, if can remember which keywords to look for, but people who just take occasional lurk, may be lost the threads, missing valueable bits and info.

How about the idea of moderated and handpicked threads list, to be of help in such cases. I also took a brave pill and linked relevant threads from other EEVBlog forum sections, if they have relevant info.
Each section is grouped around discussed matter/field or specific instrument/gear.

If you feel I missed something, let me know to add after review. If this thread is useful, perhaps Dave can make it sticky for all to see.

Can't put all those threads as stickies obviously, so this nice list will be do the job  :-+

TiN,

Since there's a 20 KB limit per message, you might want to make sure that there's room in each message so that new threads can be added to the relevant sections.

I love you TiN!!  :clap:  Thank you so much for all your hard work and effort!  This well help me a lot in the next coming year or 2 as I am starting to plan out ways I want to try to improve the multislope ADC topology.  I also want to see if I can implement those new Chinese 2DW23X zener references somehow. 

I recently started watching a few of your videos on youtube, and I am extremely impressed.
