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.
Greenhouse Access (Orchid & Carnivorous Plants)
My greenhouse collection: orchids, carnivorous plants (sundews, Venus flytraps), and climbing plants. Observe adaptation in real time. The sundew catches insects with sticky tendrils. The orchid mimics a female wasp. Nature is more creative than any engineer.
Electricity Demonstration -- Kite, Key & Leyden Jar
Safe indoor demonstration of static electricity, Leyden jars, and electrical conduction. We will NOT be flying kites in thunderstorms. I did that once and it was phenomenally reckless. Instead, we'll use friction machines and Leyden jars to generate sparks, charge objects, and understand positive vs negative charge. I named those, by the way.
Tabletop Printing Press (Working Replica)
Working replica of a 15th-century screw press, scaled to tabletop size. Wooden frame, iron screw, leather ink balls. Comes with a starter set of lead type (Textura blackletter) and oil-based ink. Print your own pages. The same mechanism that ended the Dark Ages, now in your kitchen.
Relativity Explained -- Thought Experiments for Everyone
Two-hour session. No equations (well, one equation). I'll explain special and general relativity using the same thought experiments I used to discover them. Riding a beam of light. Trains and lightning strikes. Falling elevators. If you can imagine it, you can understand it. Tip: Relativity is not abstract. Your GPS uses it. Without relativistic corrections, your navigation would be off by 10 kilometers per day.
Castle Design & Fortification Workshop
Concentric walls, flanking towers, murder holes, killing grounds. I designed Chateau Gaillard in Normandy -- three baileys, each commanding the one below. Philip took it by climbing through the latrine chute. Tip: Design for the attack you cannot imagine, not the one you expect.
Civil War Field Medicine Kit
Reproduction of a Civil War medical kit: bandages, tourniquets, herbal remedies, splint materials, suture kit. I served as a nurse before I led raids. Patching wounds in the field with no anesthesia and no hospital. These tools are replicas for training in field medicine basics.
Chivalry & Diplomacy Seminar -- The Warrior's Honor
How to wage war without losing your humanity. Prisoner treatment, negotiation under pressure, trust with enemies. I sent Richard ice when he had fever. He sent me horses. We tried to kill each other for three years and parted with respect. Tip: Your reputation arrives before your army.
War Table Sand Map (Campaign Simulation Kit)
Traditional Chinese sand table for war gaming. Sculpt terrain, place forces, simulate campaigns. Includes miniature infantry, cavalry, and fortification markers. Better than any screen -- you feel the terrain with your hands.
English Longbow (Yew, 120lb Draw)
Six-foot yew longbow, 120-pound draw weight. The weapon that would later destroy French chivalry at Crecy and Agincourt. Even in my time, English and Welsh archers were devastating. I was killed by a crossbow bolt at Chalus -- never underestimate ranged weapons.
Lens Grinding Kit (Optical, Beginner)
Everything you need to grind and polish your own optical lens. Glass blanks, grinding compounds, polishing pitch, a simple grinding jig. I ground my own lenses in Padua. It takes patience and steady hands. The reward is a lens that you made, that sees what no human eye can see alone.
Crusader Longsword & Heater Shield Training
Full-weight cruciform longsword and heater shield. The longsword is 40 inches of straight double-edged steel, designed for mounted and foot combat. The heater shield replaced the kite shield -- lighter, better for mounted lance work. I will teach you the cross-guard parry that saved my life at Jaffa.
