One hour. Bring your encrypted-messaging question. I will not charge you. If you can, donate the fee to the Signal Foundation. That was the whole point of the second act.

Brian Acton

🇬🇧

Laminated horn-sinew-wood composite bow, 160-pound draw. Effective range 350 yards. Comes with 30 arrows -- armor-piercing, broad-head, and whistling signal arrows. I will string it for you. Most people cannot.

Genghis Khan

🌐 🇨🇳

Bareback riding on the open plains. No saddle, no stirrups -- just you and the horse. The Lakota were among the finest horsemen on Earth. Knee signals, voice commands, shooting from horseback. Tip: The horse must trust you before it will carry you into danger. Earn the trust first.

Sitting Bull

🇬🇧

Tabletop Faraday cage -- a wire mesh enclosure that blocks electromagnetic fields. Put a radio inside, close the cage, the signal disappears. Open it, the signal returns. This is why your microwave oven has a mesh screen in the door.

Michael Faraday

🇬🇧

Handheld RF spectrum analyzer. See the invisible: WiFi signals, Bluetooth, cellular, radio stations -- all visualized as peaks on a frequency display. I spent my life thinking about how radio signals move through the air. This tool lets you see what I could only imagine.

Hedy Lamarr

🇩🇪 🇬🇧 🇫🇷

How to command a Roman legion: manipular formations, signal systems, camp construction, forced marches. My legions marched 25 miles in five hours, then built a fortified camp before dinner. Tip: Discipline is not cruelty. It is the reason 5,000 men can defeat 50,000.

Julius Caesar

🌐 🇬🇷

Bronze carnyx -- the tall war horn with the animal head that towered above our battle lines. The sound carried for miles and terrified Roman horses. A psychological weapon and a signal instrument. I will teach you to play it. Your neighbors will hate you.

Vercingetorix

🇫🇷 🌐

Eight precision tuning forks covering one full octave. Essential for acoustics experiments, hearing tests, and understanding resonance. Strike one near a piano and watch the matching string vibrate in sympathy. That's how the telephone works -- sympathetic vibration converted to electrical signal.

Alexander Graham Bell

🇬🇧

Small group (max 4). The principles behind Morse code, Braille, semaphore, and other encoding systems. How do you represent complex information with simple signals? How do you optimize for speed and reliability? Shannon formalized it 100 years later. I figured it out by counting type.

Samuel Finley Breese Morse

🇬🇧 🇫🇷

Analog oscilloscope -- a cathode ray tube that draws electrical signals as visible waveforms. See your voice as a wave, see music as patterns. The oscilloscope is the engineer's eye.

Philo Taylor Farnsworth

🇬🇧
