heh so ive been wanting to electronic it up a bit and tonight discovered this http://www.fasttech.com/products/1008/10000015/1001700-arduino-uno-r3-rev3-development-board and its prolly overkill for anything yeah who cares i think its gonna be a fun thing to start loving around with


so id need that
a breadboard
a power supply to the uno?
breadboard cabbbbblllleesss
and prolly some kind of display?

i mean look at this http://www.fasttech.com/products/1005/10002601/1193100-nokia-5110-8448-graphical-lcd-display-module i mean i know poo poo can be cheap but yeah that cheap? shieeeett i could make all sorts of worthless temperature sensors for like 10x the price of buying one straight out

ive just discovered fasttech which is the same but different to dx.com and anyway for like 20 bucks you could make an arduino turn a servo and maybe another 10 and you could put a laser on it and sing a coimputer and a webcam and coding effort you could make a device that actively tries to blind people by shining a laser in they eyes if they look at your web cam


have a sign above said 'cam that says "yo dont look at me or you will go blind" and after 5 seconds of face recognition it fires an infrared laser (s they cant see it) at they eyes until they can no longer see?


a prank gone too far? only time will tell

b) do this but set it up on the street somehow. itll basically end up a pyramid scheme of laughs and you will be at the top

if anyone's looking for a low cost arduino clone for their blinky-light-in-an-altoids-tin project, here's a thing on indiegogo: http://www.indiegogo.com/projects/9-arduino-compatible-starter-kit-anyone-can-learn-electronics

he's selling clones of the arduino leonardo for $9. seems pretty cool

welp fasttech does $9 shipped UNOS and like $14 megas. not sure if thats better than that

i don't know much about arduinos. the leonardo has a bunch more ports than the uno afaik. what's cool about that indiegogo guy is that the more money he raises, the more "LEARN YOU ELECTRONICS" bits he's including with each board.

why? i guess if you were doing weights that you could drop on yourself but if its like dips or things why not

this week's project: same as last week, but now in THREETHREETHREEDEEDEEDEE


so far i've got lighting figured out; holy hell it takes a long time to light a sphere though. basically doing the vector math at each point on its surface to figure out the intensity (dot product of the normal vector with the unit vector pointing at the light source)


aren't their lubraires that do this for you


or are you doing it for ~*ThE ChAlLeNgE*~

oh i'm sure i could do like

code:
import 3d

ball=([320,240,0],[127,127,255],80)
light = [500,500,500]

3d.drawlitball(ball,light)
and be done but yeah i'm doing it to learn mainly

i respect it


are you using an accepted falloff algorithm or just normal directions?

got one of those

ol qwerty bastard posted:

not sure exactly what you mean but i'm first calculating the intensity of light hitting a point as (some constant)/(distance from point to light source)2 and then multiplying that by the dot product of the surface normal (unit) vector and the unit vector from the point to the light source to get the actual brightness of the point

(then the point gets drawn as just its x and y coordinates; i'll mess around with depth and visual field and camera angles and poo poo later)

I don't mean to judge coz what you're doing is light years ahead of what I can do but [and u might not care] but that falloff your using [the reflection dimming as the angle increases] I don't think is very physically accurate at all. u may not care but either way I respect your work! u doing well m8

final thing for tonight: made the ball bounce around in 3d space with a light just off to the right of the screen



tomorrow perhaps... two balls! i already wrote the collision algorithm from my bouncysticky 2d ball program to work in 3d so that should be straightforward; harder will be getting the balls to cast shadows on each other

do some python. i'm a dumb idiot with no free time at all and even i learned to do some useful stuff with it.

the problem with python is that it owns so much and when I think about coding my arduino it's like "fuxk bro why can't I just do this or that" and eveything takes a loving hour to sort out or make it work well



python just gave me the tools to do what I wanted while c is the programming equivalent of voting in the new pope
