Suppose, we want to make an electric lamp (an oil lamp would be too easy, you just need a vessel, fuel and a wick).
Bill of materials
Generator magnet a piece of iron to be magnetized copper for wires some more iron for the armature some more scrap metal/wood/leather to make a crank and structure to house the whole thing, leather for making a pulley system for gearing Alternatively, make a lead-acid battery, or some other type of galvanic battery, depending on the available materials.
Lightbulb carbon rod for the filament (pencil lead would be ideal but I’m pretty sure charcoal will do) glass tube for the bulb itself Some copper for the connectors
Soldering Hot piece of metal or flame Pine rosin for flux Lead, tin or silver
Sprengel pump A bunch of glass tubing Mercury
Hot flame for soldering/glass blowing* Calcium carbide Water Tubing Nozzle Tin can as a reaction vessel
Equipment A forge
*no idea how I would solve the pressurized oxygen problem. Maybe instead of a tin can, use a pressure vessel for the reaction and use an old carburator (hooked up in reverse) to draw in air with the acetylene. Also, a nozzle that can take the heat… clay maybe?
Also, I just pulled this out of my ass and would probably kill myself trying to build something that wouldn’t work in the first place. So yeah, build an oil lamp, torch or candle and try not to burn everything down. It would still be a half-assed attempt at a lamp. Don’t sell yourself short.
