why?

the internet is one of the most epic breakthroughs ever. it’s why you can read this!

yet almost no one knows how it works. tragic! 🥲

the best way to learn something is to just build it!

so let’s build it!

how

every sunday i build for 3-7 hrs

i’ve never done this before so i’m learning most of it as I go

i’ll live-stream when I can, if i can’t i’ll write notes!

i’m ~60% done and it’s amazing how much I’ve learned by just showing up to try

i’ll clean up notes + publish code + DIY guide once done!!

progress

part 1: tf is the internet? (4hrs) / June 5, 2022

‣

extra notes from stream

‣

tangents

part 2: Implementing the TCP/IP Handshake (4.5hrs) / June 12, 2022

part 3: Bit Hacking & Building a WIFI Driver (7 hrs) / June 26, 2022

part 4: How Radio Works + Designing Wifi Hardware (4hrs, July 17, 2022)

note: caught flu so no live stream, here are rough notes I took from the morning!

part 5: Buying HW

going to try sending fm radio through gpio4 pin on raspberry pi 3 A+

flashed microSD card with RasbianOS, setup on the PI 3 A+, downloading updates… wild that this lil board has internet + g

tangent: the PI 3 A+ has 1gb GpU ram + 32gb storage on my ssd

if i find a way to load one layer of torch inference server 1 at a time i can technically do a full gptj inference on raspberry pi

tangent: this raspberri pi is more than 100 thousand times stronger compute than the control system that helped us get to the moon in the Apollo 11 mission

to setup the radio device followed this guide: https://www.section.io/engineering-education/broadcasting-a-pirate-fm-radio-station-using-a-raspberry-pi/

iphone seems blocked on this bcz it doesn’t have internal fm radio receiver so just uses apps that listen to stations and shares to iphone over wifi, not true radio

android has fm tuner but need wired headphones to act as receiver antenna

let’s build the internet from scratch!
