starlink

a 16-year-old kid built a prototype of starlink and made 300,000 dollars. what's more, the device can pick up satellite signals and works everywhere in the world. even if spacex tries to block this, the kid has already taken his precautions. what he did isn't as complicated as you'd think. he developed it almost entirely with claude's help.

first let's clarify this: he isn't stealing starlink's internet. what he's using is the radio beacon signals broadcast by spacex's satellites. he uses these signals like a free positioning system. this way he can determine location even in regions where gps doesn't work or is being jammed.

every starlink satellite continuously broadcasts a beacon signal. these signals can be picked up with a small dish antenna and a 35-dollar sdr receiver. triangulation is done using at least three satellites, and location can be calculated even without gps. this method is being tested by the us military too. the kid turned this into a portable device and sold it to hikers, sailors, and emergency teams.

the equipment he used:
rtl-sdr blog v4 usb receiver — 35 dollars
small dish antenna — about 50 dollars
ku-band lnb converter — 20 dollars
raspberry pi 5 (8 gb ram)
bias-t adapter
5000 mah usb power bank
total cost: 180 dollars.

he had claude write a python program that captures the starlink beacon signals and calculates location using tle data and doppler shift. when the program runs, the raspberry pi tracks the satellites and shows coordinates with roughly 10-30 meter accuracy. no gps. no phone signal. no internet.

afterward he made a case with 3d printing and sold the product under the name hikers & sailors gps backup.
unit cost: $180
sale price: $899
profit: $719
he sold 350 units.

among his customers are fire crews, pilots, skiers, and yacht owners. spacex can't file a lawsuit because picking up publicly broadcast beacon signals is considered legal.
