ol qwerty bastard posted:so i have this plan to build a semiautonomous UAV; the physical airplane part is easy enough but i want to stuff it with the guts of an old phone so i can preprogram it with GPS coordinates that it will fly to usb sucks to work with, phone accelerometers should be called isthephoneupsidedownornoters and are pretty much useless beyond that so good luck getting useful ins done with them, also phone gps is pretty crappy even by gps standards so just even more lol im basically just here to poo poo on your dreams, sorry realistically you could do it okay with a gps receiver from sparkfun which has the added bonus of not androiding your battery life, working well with an arduino, and being at least decently accurate. still won't be able to land but for flying to some coordinate position itll do okay until it's close.

ol qwerty bastard posted:no i definitely want to hear what parts of my plan aren't realistic, so it's good to know it depends on how much you wanna do yourself and how much you wanna spend but you can buy pretty heavily integrated avionics packages that'll do lots of sweet poo poo for you like poo poo on this page https://www.sparkfun.com/categories/160 which'll integrate accels and gyros and they probably won't suck as much as phone accels the thing with MEMS accelerometers and gyros is that you pretty much always get what you pay for. the ones in phones are basically the cheapest you can get that still function, since pretty much their only use is "which direction is down relative to the screen". cheap accels are fine if you just want to know instantaneous acceleration, but once you start integrating for velocity and displacement the errors start adding up hilariously quickly. realistically though you're not going to be able to buy good enough accels for decent position data longer than half an hour or so and that's only if you're shelling out thousands. idk much about UAVs though last time i was loving around with GPS and inertial navigation was on a boat, and GPS was more than adequate for our needs. we used one of these receivers and it put our boat within a couple feet of our target pretty reliably: https://www.sparkfun.com/products/465 as an added bonus they're dead simple to use. ive actually got atmega C code around here somewhere for talking to one, although there's almost certainly a more integrated arduino solution.

coffeetable posted:yeah GPS is accurate to within a few meters, and it's improving every year. there's also the ESA galileo constellation going up between 2014-2019, with an open signal accurate to within <1m + a commercial signal accurate to <1cm same for the GPS L5 bands which are already going into service, but receivers for them seem to be hard to come by still, at least on the cheap end. i dunno, i haven't dealt with this poo poo in a couple years. definitely beats the 90s when gps was intentionally crippled on the non-mil bands though

Ana5000 posted:And what's stopping them from adding a camera and image recognition software for the missile to periodically literally look where it's going? no real disaster-level (eg nuclear) weapons even bother to use anything external whatsoever these days. They use strictly INS and star sighting systems. Pretty much all branches of the military are prepared for GPS-denied combat, because any war on a reasonably even technical battleground (like vs europe, china, russia, india) will very likely see use of at least local or widespread GPS/related jamming.

Moist von Lipwig posted:A 315 deadlift for reps is pretty achievable for any dude, come hang in YLLS i do hang in ylls but i get really bored of lifting around the time i can do a few reps of my body weight i'd rather just bike generally also im so awful at bench pressing that lifting just demoralizes me. like my form is okay and stuff i just plateau at like 100-110 pounds and its just shameful and i get uncomfortable increasing my squat weight because i lose confidence in my lifts even though my form is fine and everything i just dont like pushing it past like 150 liftchatsnype

Mido posted:yo could you recommend a good simulator? i keep finding lovely java ones but im convinced there's some nerdtool that is exactly what i'd like it to be (drag components onto a space and connect them and inspect voltage and see things happen etc) didnt bother to look to see if this is answered but there's about a million spice variants that you could use. i usually use ltspice for no particular reason. its free and has the features you mentioned.

actually dealing with solving the differential equations for a tepid pool machine sounds completely overkill. stick in a large K, a medium D, and a small I and try it out.

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

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.

hubris.height posted:you edited out the perlin noise thing which i'm doing reading on right now. its interesting but not really super relevant i think but i dunno it could be interesting velocity is just the integral of acceleration, so no, smooth velocity does not mean a uniform rate of acceleration. smoothness is just differentiability (as in http://en.wikipedia.org/wiki/Differentiable_function ).

Detroit Q. Spider posted:https://www.youtube.com/watch?v=RESnZ8woNZI tases are designed to be repeatable on real platforms and great care is taken to ensure it to the point that people have modified n64 controllers to precisely play back the control inputs used in the emulator stage to a real n64 and then record that whole thing for verification it mostly only matters when new glitches are discovered to verify that they are game glitches and not emulator glitches
