The Binary Calculator for all 0b10 Types
You know the old joke: There are 10 types of people in the world — those who understand binary, and those who don’t. Most of us on Hackaday are firmly in the former camp, which is why projects like this circuit sculpture binary calculator really tickle our fancies.
Inspired by the brass framework and floating component builds of Mohit Bhoite, dennis1a4 decided to take the plunge into circuit sculpture in an appropriately nerdy way. He wisely decided on a starter build, which was a simple 555 timer circuit, before diving into the calculator.
Based on an ATMega328P in a 28-pin DIP, the calculator is built on an interesting hybrid platform of brass wire and CNC-routed wood. The combination of materials looks great, and we especially love the wooden keycaps on the six switches that make up the keyboard.
There’s also some nice work involved in adapting the TLC5928 driver to the display of 16 discrete LEDs; suspended as it is by fine magnet wires, the SSOP chip looks a bit like a bug trapped in a spider web.
If you're interested in making your own version, PMD Way has you covered with a huge range of parts including ATmega328P microcontrollers with bootloader, LEDs, tactile buttons, jumper wires and more.
