Although that is usually the case, it is not always the case - I've seen some batches of LEDs, rarely, where it isn't.

content: Wow, I can't believe it's been 2 years since I did this v3 µRulerGuess I should get off my arse and do some more.I'm just looking at it again and thoughts on the back side imperial scale. Do I need all those different scales? (might be confusing?), or will just two different ones be enough? If so, which ones?, I'm not a Yank so I don't really know what are the most used imperial scalesOther stuff to add/remove?

author: CatalinaWOW
author_rank: Super Contributor
timestamp: October 20, 2016, 12:42:58 am
content: I am sure there are many opinions on this, but the only imperial scales I use with any frequency are tenths, eighths, quarters. Sixteenths occasionally. Thirty seconds and sixty fourths never. Same for twentieths and fiftieths and hundredths. When needing more accuracy a ruler isn't the tool and decimal fractions are the answer, even in Imperial units. I have never seen a micrometer calibrated in 512ths or whatever, and most of the calipers which have fractional scales also have sensible decimal scales.I would consider extending the temperature conversion table to cover temperatures found worldwide. -40C to 60C would cover ski areas and northern Europe, while getting most of the automobile in the sun temps. The five deg C resolution is appropriate. If you need tighter you go to your calculator or a bigger table.

content: As a mostly metric animal, I think 20ths of an inch are occasionally useful, I think you may as well keep them there (at the very least, as the little minor ticks). I must point out that there are two separate sections of the ruler there marked "1/10" and "1/20", but they look identical. It's obvious that tenths are the big ticks and 1/20 are the small ticks, but it still irks me that they're labelled as if to imply that the two sections are different in some way.I'd be very keen to keep the 32nds. So I guess I'm suggesting, drop the 1/50, and drop the 1/64. At least that's symmetrical, one off each side.I really like the design in the 1/32 section, with the ticks of 3 different lengths -- there is some argument perhaps for just extending this along the entire ruler?

content: The things on the German ruler, and to some extent Dave's, would be better served printed single sided on acetate (or a more modern equivalent). Easier to lay the footprints over the top of a PCB to see what size they are. Maybe the ultimate version would have several, pinned together at one end like a set of feeler gauges. That would free up more area to include all the good ideas that everyone has come up with. And to do things like showing voltage spacings physically, so you could put the ruler over a board and see directly what voltages were supportable.It would help in resolving a fundamental conflict with this ruler, which is trying to be two things - a measuring device and a pocket reference.

I know what you need: a longer ruler ;-) Anyways, when it comes to tables (which consume a lot of space unfortunately), frequency and time vs wavelength would be nice.Tables are easy to print on paper or to view on a monitor. I think most practical for such a ruler are different pad sizes, distances, foot prints, Rack Unit heigts, drill sizes for bolts and clearance for nuts, ... that sort of thing.Or embed a button cell and some different color LEDs with known wavelengths.

content: Quote from: EEVblog on October 21, 2016, 01:30:02 pmI have the ADAfruit ruler and it has a good assortment of footprints. It is somewhat useful when etching your own boards at home to have a professional made board to compare with. The thing I use the most are the hole table/ wire gauge and your existing ruler is more comprehensive in that regard. Selfishly I would ask you not to include footprints as I already have the Adafruit for that. I do want to order something close to your last ruler so get busy making them! (please!) vox populi has spoken!
