Pseudonymous maker “diorama111” has an obsession with miniaturization, which has culminated in a powerful creation: a useful “micro” Nissan Micra, with headlights, flip indicators, and movement, constructed to a 1/A hundred and fiftieth scale.
“[This] 1/150 scale automobile runs alongside [a] wire embedded beneath the highway,” diorama111 explains of the machine, which is well balanced on the tip of a single finger. “Begin, cease, headlights, and switch indicators are managed by distant management.”
Regardless of its diminutive measurement, the automobile is successfully self-contained: contained in the automobile, which has a 16.5mm (round 0.65″) wheelbase and 4mm (round 0.16″) tyres, is a tiny 30mAh lithium-polymer 3.7V battery which drives a Microchip ATtiny1616 microcontroller, the lighting system with useful and independently-controllable left and proper flip indicators plus headlights, tail lights, and brake lights, and a steering mechanism.
“The steering strikes alongside embedded wires,” diorama111 admits, “so the automobile can solely run on a set route.” Regardless of this, it is solely useful — and constructed by hand, with tweezers, tiny drill, and persistence. “The battery is charged by inserting a small self-made charging pin right into a gap on the underside of the automobile.”
Management of the automobile comes by means of a handheld distant, permitting the automobile to drive alongside a miniature roadway, cease at site visitors indicators — exhibiting off the working brake lights — and switch corners, with or with out indicating.
The complete construct is detailed within the embedded video and on diorama111’s YouTube channel; the maker has additionally revealed a schematic for the electronics and supply code for the microcontroller’s firmware.
