a msp430 is like five dollars and im pretty sure i read something that they made a newer revision of it and now its the most energy efficient microcontroller or something.

ahhh spiders posted:lol that's terrible. oh well i guess that's why it costs like $30 or whatever the best part is that i started out simple with an arduino, a humidity sensor, and a wi-fi "shield" that just snaps on top. for the initial tests i made it send a http request to my server once every 5 miinutes when I got the ~10 hours of battery life i was like "oh, well, the wifi is always on, i should put that to sleep" so i spent a bunch of time setting up this "deep sleep" mode on the wi-fi shield where the arduino could wake up the wi-fi stuff from its sleep, and made it so it only woke up once every 30 minutes. "this should make it last six times as long!" but no, the arduino was the power hog the whole time. the battery life was barely any different.

Werthog posted:nobody in yospos is dumb enough that they can't use a real microcontroller instead of some lovely dev board loaded up with unnecessary poo poo that sucks power and leaves you with no room for your code. I only posted that gameduino poo poo because an accessible forth cpu seemed neat its me i'm the guy wayyyyyyyy too dumb to use anything but an arduino but i don't do anything but sit at the wall and ponder the best way to cut my own brake lines

I can barely handle amps and volts but then you get to AC poo poo and there's frequencies and inductances and phases and jyfdjytdkuyewttsuted now I code java for money

ahhh spiders posted:lua ftw ive been doing interviewstreet challenges to learn how to do Real Programming Problems for some reason, they have support for loving lua, but not javascript. i'm using python instead but still, what the gently caress? ugh. e: also if anyone can give me hints on the "unfriendly numbers" challenge (not a solution obviously!! i aint no cheater) that'd be nice; i timed out on the last 3 test cases. it really sucks that they don't show you any details about the test cases
