The tutorials are pretty good. Keep them coming. smiley

Actually, K is 1000 in communications
Actually communications uses bits and 1024. Storage uses bytes and 1000. smiley-razz

i need to write a tutorial for tutorial writers smiley

Ladyada, there is a good reason for defining KB as 1000 bytes and MB as 1000 Kbytes and GB as 1000 MBytes in the storage industry.  Actually, K is 1000 in communications, and other measurements in the decimal world.  Maybe 1024 = KB and 1024 * 1024 = MB is the one that is not natural, because it is binary, which is common in digital computers (basically memory addressing).  Hard disks doesn't need to be addressed in binary, they can be addressed in decimal, which is more understandable, so I don't think it is a marketing trick created to make the HDs look much bigger... marketing people are not that smart ;-)  Probably they don't even know how a HD looks like!


the issue is if you have a "100 megabyte file" (as your file manager reports) its going to take up 100 * 1024 kb. however a 100 megabyte diskdrive only stores 100 * 1000 kb.

anyways, its just a stupid math example. if you can think of a better example that uses the same elements, let me know and i can change it.

ill fix the baud thing. huh i guess im relying on old stuff in my brains smiley-sad


ah, now i see, baud is symbols per second. well, in this case baud does = bps. more importantly, Baud is what is used in the Arduino serial monitor.

i think the important thing to remember here is that yes, there are many little approximations. i know they're there. its impossible to note all of them because then its confusing to the learner. i have to focus these tutorials on teaching the basic stuff. later on they  can read all about baud rates and RLE encoding schemes.

You might also want to separate into 3 docs, one for Windows, Linux and OSX as including all three adds considerable bulk.

i usually do after the tutorial is done, just because editing it in one file is much easier.

Also, you missed the picture of the dc power jumper.  All it needs now is a kitchen sink smiley-wink

i have to retake the photo

i offer air mail and even though its somewhat unreliable, ive -rarely- had packages be completely lost. most people are pretty much ok with the failure/delay rate for small items.
