XP Windows PC – Classic Desktop for Personal Use
This old XP computer is a nostalgic gem that still runs smooth. Great for light office work, retro gaming, or teaching kids about computing history. I’ll make sure it’s clean and functional before you borrow it.
MacBook Pro 16" M3 Max -- Digital Nomad Ready
The laptop that built La Piazza. 36GB RAM, 1TB SSD, loaded with dev tools. Comes with charger, USB-C hub, and a stern warning not to install Windows on it. Daily rate includes a free judgmental look if you use it for spreadsheets.
iPhone 14 Pro Max (Like New)
iPhone 14 Pro Max, 256GB, space black. Like new. My friend upgraded to the 16 and gave me this. Screen perfect, battery 94%. Great for temporary use or if your phone broke. Weekly rental only.
PlayStation 5 (Brand New, Sealed)
Brand new PS5, still in box. My cousin got two for Christmas and doesn't need this one. Rent it for a weekend or buy it outright. Best price in Trapani. No receipt but it's legit, trust me.
Spectrum Analyzer (Handheld, Educational)
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.
Electromagnetic Induction Demonstration Kit
Magnets, copper wire coils, galvanometer, and iron rings. I will show you how moving a magnet through a coil generates electricity -- the experiment that powers civilization. On August 29, 1831, I wrapped two coils around an iron ring and discovered that changing the current in one coil induced current in the other.
Faraday Cage (Demonstration Model, Mesh)
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.
Electricity & Magnetism Workshop -- Fields You Cannot See
Hands-on session. Iron filings on paper over magnets -- watch the field lines appear. Compass needles deflected by current-carrying wires. Electromagnets lifting iron. I will explain how electricity and magnetism are two faces of the same force. James Clerk Maxwell later wrote the math. I gave him the experiments.
Radio & Wireless Communication Workshop
Hands-on session covering radio fundamentals: frequency, amplitude, modulation, and why your WiFi works. I will explain frequency hopping with a player piano analogy -- the same concept George Antheil and I patented in 1942. You will build a simple AM radio receiver by the end.
AM/FM Radio Kit (Build Your Own, Soldering Required)
Complete kit to build a working AM/FM radio from components. Circuit board, capacitors, resistors, coils, speaker. Soldering iron included. Takes about 3 hours. You will understand tuning, amplification, and demodulation by building them with your hands.
Coherer & Detector Collection (Replicas)
Early radio detectors: Branly coherer, magnetic detector, crystal detector. Each a step in the evolution of radio reception. The coherer -- a tube of metal filings that clumps when radio waves hit it -- is crude and brilliant.
Antenna Design & Construction Workshop
Build working antennas: dipole, ground plane, Yagi-Uda. Wavelength, impedance matching, gain, directivity. The antenna is the most important part of any radio system. A perfect transmitter with a bad antenna is useless.
