they're nifty little $3 wifi-connected Arduino things

Oh, sounds interesting

the meme project is making your own amazon dash button basically

I used to play around with arduino and stuff I bought off aliexpress

Almost made a self driving Rc car

cool

radar?

Loads of ultrasonic receptors, ir luminosity detector and a specially made cardboard black and while road

It could detect any obstacle, drive around obstacles, follow a curvy road, self park between two vehicles or obstacles

Basically every single "function" worked. But somehow putting everything together was impossible

yeah the complexity management for building a system like that explodes quickly

it's easy to make something with linear inputs

line follower is okay

more than one condition is ehhh

paralel processing is where it gets fun

i loved that shit in Automation engineering

right, it becomes a design project for school

not really a hobby thing

well it could but

it would... tromp my other hobbies

That car was my 'computer science' project in senior year of high school

That was a few years ago

I'm actually pretty proud of what I did back then :>

novadays kids do that shit with machine viewing and object regonition

ya should be

makes me feel oldschool relying to simple sensors

^

well it all boils down to sensors; it's how you deal with that data / what structures and analysis you do on it after that makes it fancy

it's not horribly hard just a paradigm shift

not like, a C-microcontroller project

i have some plans start playing again with multiwave Lidar setups but i wonder if it will ever happen

How affordable are lidars for home projects like these? Is buying these things actually possible

cheap

specialy if you dont care about accuracy at start so much

50usd or less for all the toys at max

_if you have some basic tools ofc_

Yeah..

I'll gear up step by step

Buying everything at once doesn't seem useful anyway, especially for a not broke but not like super rich student

heh i just got an idea to make a trolly "come hither" kiosk thing using one of these $15 distance sensors

Gonna make a purchase on aliexpress, got any 3-4$ idea for a random thing I can throw in with it
