I don't have a lot of time, just 20 minutes, so I built a small but useful motorized tripod for USB-powered supply. It has an Arduino controller. Used items: Mechanical: - 1x bearing 608zz, 22 x 8 x 7 mm (outside diameter x inside diameter x width) - 4x M3 nuts - 2x M3 washers - 2x M3 bolts, length 10mm - 2x M3 distance pillars, length 20 mm - 2x M4 bolts, length 14 mm - 1x M8 bolt for bearing, length 25mm - 1x metal sheet from a can, 10 x 42 mm (for easily sliding a big gear) Electrical: - 1x Arduino Pro Mini 168 (or any similar you have) + wires + cable with USB-A plug - 1x stepper motor driver 5V DC - 1x 28BYJ-48, stepper motor 5V DC - 1x Tactile button (or more if you want) - 1x 10 kohm/0.25W resistor - 1x LED blue 5mm (or any 5mm LED) - 1x 300 ohm/0.25W resistor
