    How to Use Calipers

    Sir. You write:”In the tennis ball photo it looks like 2-1/2 or 2.50 inches plus 1/128"So, what do You do here is that You divide a inch 1/128 plus it to what WHY?Where does that 1/128” come from?

    Ooh.. I did re-read your coment. ”because there are divisions of 0.025 mm between the numbered 0.05 mm divisions” ?? There’s no such a reading. A mechanical caliper reads only up to 1/10’th of a mm. NOT to a 1/100 of mm. (0.05 mm) as you suggest (or even 0.025mm?).Those measurements in those limits would require a ”micrometer”.Com’n, to read a caliper on mm. scale (SI) is as simple as it can get.You just read read the mm on the scale, and if it appears to owershoot the exact line on the mm. scale you check it on the Vernier part there the lines match, and that would be the fraction of mm. on the main scale + the Vernier. No calculation needed here.A thumb rule here, (actually it’s the real rule), You can’t make more exact measurements than 1/10’th of a mm. with a caliper, (next step will …

    You'r ible is really needed for, say, youngsters (you know, them young people), fair enough, BUT, really: Go with SI-system, that is: in this case in millimeters.. Reason to why to do this: The US. Imperial with them inches, if not yet but in close future, will be using the SI-system even for you ower there behind the pond.Did you know that them astronautical- and astronomical- (Nasa included), +++ many othershave used the SI eversince the -50's ? Why? (humor) e.g. the distanance to the moon could be something like 45,8444,254,255,003 5/8 of an inch (count that), ok, you could trnslate it to feet, and then to yards and then to miles.... Geee I'll give up :)FOR GODS SAKE go ower to SI-system Cheersps. plz. don't get affended

  • Portable Function Generator on Arduino

    I guess it's rather difficoult to generate some specific waweforms just with "software", maybe..?? don't know. So it goes more to on "conventional" tech's because them MCU's like ATMEGA don't heve a built in D/A converter, (they do have this A/D converters).

    Gee.. You did a great job with your 'ible, ( I know, I'we done some?, even pupblished). Hope getting more of You'r doing's

  • The Unpluginator - Self-Unplugging Useless Box

    You gave me a laugh, thanks. I see you having a "bunch" of capacitors there. Wouldn't it be better to use a cap. in order of Farad? I know, these caps are for 2Volts only but anyway...
