Free-form circuit structure

By Ben Everard. Posted

Individually cut brass rods must be a pain to work with. Unlike copper sandwiched between layers of PCB substrate, copper wires aren’t obliged to stay where you put them; just a single wobble, a single component out of place makes the whole thing look wrong.

Knowing that, and how hard it is to produce a free-form circuit sculpture, makes us appreciate Mohit Bhoite’s work all the more. This tiny model lunar lander does nothing but display the temperature, but it does it with such panache that we’ve got to include it here. Components, as well as function, are minimal: he’s used an ATtiny861A microcontroller and a BME280 sensor, powered by a CR2032 coin cell.
