THIS GUY LIVES UNDER SFO'S TAKEOFF PATH SO HE BUILT A CEILING PROJECTOR THAT TRACKS EVERY PLANE FLYING OVER HIS HOUSE IN REAL TIME
he uses a cheap $30 radio receiver to pick up the signals that planes broadcast while flying.
then projects them onto his ceiling in real time
when a jet flies over his house you hear it outside and at the exact same moment a plane glides across his ceiling labeled with the airline, aircraft type, and destination
pure black background so the projector's rectangle disappears and only the aircraft are visible
but he didn't stop at planes
it also draws the real sky behind them. sun, moon, bright stars, constellations, and live satellites including the ISS. all at their true positions for his exact location and time in real time
so he's lying in bed watching the actual night sky projected onto his ceiling with real planes crossing through it as they take off from SFO
there is a huge market for every man alive that runs outside to see the helicopter
vibe coded the whole thing himself with a cheap radio, a projector, and some clever software
I just broke down the anatomy of the perfect SOUL. md file for AI agents.
SOUL. md is the identity file every AI agent reads before it does anything else.
Without it, your agent is just a raw LLM with no memory, no personality, and no boundaries.
With it, your agent knows who it is, how to talk, what to refuse, and which tools to use.
Here are the 9 sections that make a SOUL. md actually work:
→ Identity (who the agent IS, not what it does)
→ Values (decision-making when rules don't cover it)
→ Communication Style (tone, length, formality)
→ Expertise (specific tools and domains, not vague "knows things")
→ Boundaries (the immune system. Holds even under pressure)
→ Workflow (step-by-step process for every task)
→ Tool Usage (WHEN and HOW, not just which ones exist)
→ Memory Policy (what persists, what gets wiped)
→ Example Interactions (one good example beats 10 abstract rules)
Most people write "Be helpful and professional."
That describes nothing. Every AI already tries to do that.
The agents that actually work have SOUL. md files with real opinions, specific limits, and concrete examples of what "good" looks like.
A strong SOUL. md is 200-500 words. Shorter = sharper agent.
Save this. You'll need it the moment you build your first agent.

Works while you sleep.
The people who build this tonight will never work the same way again.

.@johanknorberg warns America, “Don’t get cocky.”
Look at his country, Sweden - politicians passed socialist policies.
“It almost killed the Swedish economy.”
@mr_r0b0t@NVIDIAAI I love mine, I have done a lot of projects on it, fine-tuning LoRa adapter, ai vision, creating training website, built my own personal assisstant, and a lot more
