Individual spot ingredients list ------------------ - LED (warm white, 5mm, Digikey part 1080-1006-ND) - 82Ω resistor, ¼W, 3mm (Digikey part S82QCT-ND) file can be easily tweaked for larger resistors. - LED spot shade (led_spot_shade.scad) - super glue - LED spot magnet holder (led_spot_magnet_holder.scad) - 2× cube magnets (4mm to each side. Unfortunately, the source I got mine dried up when they became illegal to sell. The magnet holder file can be automatically-adjusted to fit any size cube magnets by tweaking the magnet_size parameter.) - magnet wire (22 gauge, 50mm wire per spot) - reflector: thin, flexible shiny material that can be bent into a cylinder (I used some scrap metalized anti-static bags) 10x26mm rectangle per spot - if the magnet wire is not ferrous, scrap ferrous wire (a 3-4mm sections per spot. I used scraps cut from the resistor leads, which were ferrous) Tools ------ - soldering iron, solder - needle-nose pliers - scissors or knife - sandpaper or a metal file
