i think for my purposes i'll just use the arduino autotune library.

c is the simplest thing. i think everybody understands pointers at this bit, then its p much enums, structs and dont forget to break out of your cases. its just that ppl take a look at linux.c and freak out cause macros? idk.

if you wanna actually learn from your idiot spare time project do it in c it won't be that bad and you'll learn a whole bunch if you're using msp430s which i think you said you were then its quite easy how to do embedded development: 10 read the datasheet 20 goto 10

i really want to be cool and awesome and etch my own pcb and surface mount everything cause i deserve the best techmology has to offer.  i had the idea of adding an rfid reader and labelling my sealed food with rfid stickers so you could just tap the sticker on the machine and it would set itself to the right temperature. one can dream...

WorkingPeer posted:i was gonna go for the atmega328p oh okay. also a reasonable choice, also pretty harmless in c. WorkingPeer posted:i really want to be cool and awesome and etch my own pcb and surface mount everything cause i deserve the best techmology has to offer. don't bother etching your own because getting good-looking pcbs done elsewhere is insanely cheap and the results are way better than you can do yourself, particularly when you need SMD tolerances. also, soldering smd by hand really is not difficult, the only bits i avoid are 0201s, packages without leads (eg QFN), and physically inaccessible packages (eg BGA). pretty much everything else is really not particularly difficult even with lovely equipment. surface tension is kinda magical.

oh cool we're onto electronics projects i had an idea for a big ol' button i could whack to make a noise. searched the internet and all i got was a bunch of idiot makers "hacking" a radio shack voice recorder into a staples easy button. what's the easiest/smallest/cheapest way to make a small circuit that just plays back a sound file

more python graphics stuff: i modified the langton's ant algorithm so that the trail would fade slowly, which was interesting but it always still ended up in the same pattern so then i added random cell activations to disrupt that  i call it "ant in a rainstorm"

ol qwerty bastard posted:hm okay clearly my ball collision algorithm needs work i like your version of physics. it's more fun. (by any chance did you design it so collision boundaries strongly repel eachother? because then if two boundaries are found to be intersecting at the end of a time step, the repulsion would force one ball into the other)

coffeetable posted:i like your version of physics. it's more fun. it's supposed to detect when the distance is less than (r1+r2) and then apply a force to each based on their velocities and masses but i'm getting some weird negative numbers in a place that should only have positive numbers (i.e. under a square root) and i don't know if it's because i hosed up somewhere or because floating point handling in python is apparently lovely this would be a lot easier if i just said that both balls have the same mass and made the system symmetrical but that's kind of boring

hah it totally was just a sign that i had flipped, and also i'd forgotten to divide by 2 when figuring out the kinetic energy so it was doubling in energy upon every collision

i figured out that KSP only has such bad lag with big structures because the physics calculations on the unity engine only happen on one core. wish i was a big enough badass to come up with a workaround

the workaround is to wait for them to port it to the newer version of unity (they are planning this for the next major update)
