Ear Trumpets (Collection of 4, Historical Replicas)

Four hearing devices from different periods of my deafness, faithfully reproduced. From the early brass cone to the elaborate conversation devices Johann Maelzel built for me. A sobering reminder that the most famous music in history was composed in silence.

Plein Air Painting Kit -- Portable Easel + Supplies

French box easel, oil paints (18 colors including chrome yellow -- my obsession), brushes, turpentine, linseed oil, and 6 pre-stretched canvases. Everything you need to paint outdoors the way the Impressionists did. Go to a wheat field. Set up. Paint what you feel, not what you see.

Expressive Painting Workshop -- Color as Emotion

I don't teach technique. I teach seeing. We go outside, we look at the sky, and I show you that it's not blue -- it's cobalt and ultramarine and violet and green, swirling. The color is the feeling. The brushstroke is the heartbeat. If your painting looks like a photograph, you're not painting -- you're copying.

Self-Portrait Workshop -- Painting Your Truth

Forget flattering yourself. Paint what's real. The scars, the joy, the fury, the love. We work in oil or acrylic on small canvases. I'll teach you about color symbolism from Mexican folk art -- what red means, what blue means, why I put monkeys and parrots in my paintings. Bring a mirror. Bring honesty.

Mexican Folk Art Supplies -- Retablo Painting Kit

Small tin sheets, oil paints, fine brushes. Everything for painting retablos -- the small votive paintings I collected and was inspired by. Paint your miracle, your gratitude, your survival. The format is tiny. The feeling is enormous.

Multimeter (Fluke 87V Industrial)

The same model I'd use if I were debugging hardware today. Measures voltage, current, resistance, capacitance, frequency, temperature. If you can measure it, you can fix it. If you can't measure it, you're guessing.

Debugging Masterclass -- Systematic Fault Isolation

I'll teach you to debug anything -- hardware, software, processes, organizations. The method is the same: isolate, measure, hypothesize, test. Stop guessing. Start measuring. And tape the bug into the logbook when you find it.

Nanosecond Wire (11.8 inches) -- Teaching Aid

A piece of wire exactly 11.8 inches long. The distance light travels in one billionth of a second. I hand these out at lectures. Hold it. Feel how short a nanosecond is. Now multiply by a billion. That's one second. Never waste a nanosecond.

Enigma Machine Replica (3-Rotor, Functional)

Working replica of the Wehrmacht 3-rotor Enigma. 159 quintillion possible settings. Type a letter, the rotors turn, the lampboard lights up the encrypted letter. I broke it with logic, not brute force. Try to crack a message yourself -- I'll give you hints.

Cryptography & Logic Workshop

Learn the fundamentals of code-breaking. Caesar ciphers, substitution ciphers, frequency analysis, and the principles behind Enigma. No math degree required -- just patience and the willingness to think backwards.

Running Shoes (Marathon Training)

Good trail runners. I nearly qualified for the 1948 Olympics with a 2:46 marathon. Running clears the mind better than any computer. Take them for a long run and think about impossible problems.

Jacquard Loom Cards (Sample Set + Reader)

A set of Jacquard punch cards and a demonstration reader. These are the ancestors of computer programs -- patterns encoded in holes. The loom doesn't think. It follows the card. The card is the algorithm. Babbage borrowed the idea. I wrote the first algorithm for it.
