Electrical Wiring & Circuits Workshop
Hands-on workshop: wire a circuit from scratch. Series, parallel, switches, fuses. We build a working lamp by the end. Tip: Always check the circuit BEFORE you connect power. I lost part of my hearing to an accident. Learn from my mistakes, not my losses.
Telephone Prototype (Working Replica, 1876 Model)
Working replica of the original electromagnetic telephone. Two units connected by wire. Speak into one, listen on the other. The sound quality is terrible by modern standards. But the first time you hear a voice come through that wire, you'll understand why I shouted for Watson.
Tuning Fork Set (Scientific Grade, 8-Piece)
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.
Morse Code Workshop -- The Original Digital Language
Learn Morse code -- the first digital communication system. On/off, long/short, 1/0. In two hours you will send and receive at 5 words per minute. We use a real telegraph key and sounder. Tip: Learn the rhythm, not the dots and dashes. Your ear learns faster than your eyes.
Telegraph Key & Sounder Set (Working, Brass)
Brass telegraph key and electromagnetic sounder connected by wire. Press the key, the sounder clicks. The same setup that connected America coast to coast. Includes battery and wire. Set up two stations across a room and send messages.
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.
Spark Gap Transmitter (Demo Model, Low Power)
Low-power replica of an early spark-gap transmitter. Generates broadband radio pulses you can receive on an AM radio across the room. The crackle of the spark, the hiss in the receiver -- this is how the Titanic called for help.
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.
Television History & Electronics Workshop
How I built the first electronic TV. Electron beams, phosphor screens, scanning patterns. We will build a simple cathode ray demonstration and understand how 525 lines of light become a moving picture.
Oscilloscope (Analog, Teaching Model)
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.
Soldering & Circuit Building Workshop
Learn to solder, read circuit diagrams, and build a working electronic project. Through-hole components on perfboard. I built my first TV transmitter in a rented apartment. You will build something simpler but learn the same fundamental skill.
Phone Screen Repair Service
Cracked screen? I fix iPhones, Samsungs, Pixels, and most Android phones. You buy the screen (I'll tell you which one), I do the labor. 30 minutes to 1 hour.
