Zoborg: Cyborg Darkling Beetles with Elytra and Pronotum Implants Researchers, with support from The University of Queensland and other institutions, developed Zoborg, a living darkling beetle that was turned into a cyborg using an electronic wireless backpack mounted on its body. The backpack is tiny (15.8 mm x 5.8 mm, weighing 160 mg) and includes an ATtiny85V microcontroller and an infrared receiver. Electrodes are implanted in the elytra (hard covers on… |

Tetromino: Tiny Tetris Console Powered by an ATtiny In the past, we have seen many variations of tiny game consoles. Franco Trimboli, aka sunpazed, a maker from Melbourne has shared his own spin on the tiny game console, called Tetromino. As you can guess from the name, it is a tiny Tetris console the size of a keychain. The brain of Tetromino is an ATtiny85 chip from Microchip. For display, sunpazed chooses an easy to find OLED module… |

Artificial Arduino Candle Light Turns on with Fire and Flickers like a Real Candle Winter is coming and that simply means cold weather with early nights. The perfect way to combat the winter gloom and lighten the mood is to light some candles but burning wax candles inside a closed room will fill up the room with carbon dioxide which can cause health issues. That is why in this article we have decided… |

Build a Battery Internal Resistance Meter with Arduino and Atmel ATtiny85 IC In an ideal scenario, a battery should have zero internal resistance. But batteries are not made perfect and the electrodes are not 100% conductive, which creates a small resistance within the battery called internal resistance. Practically batteries will always have some internal resistance. On paper, the value of the resistance will appear low around 0.1Ω for… |

DIY Filament Runout Sensor for 3D Printer Fault Detection using Arduino 3D printers have become an essential aspect of quick prototyping and have reached out to a wide range of makers and engineers. But most of these printers are hobby grade and hence require constant tinkering and repairs to keep them working. Among all challenges, 3D printer filament breaking or tangling is one of the most common problems that everyone who… |

Programming ATtiny85 Microcontroller IC with Arduino Uno ATtiny85 Microcontroller Chip is an affordable and powerful alternative to other Arduino microcontrollers, especially when you want to shrink your project down. The chip features 8 pins out of which six are I/O (Including Reset) pins and two are power pins. But how do you program it as it doesn’t have a USB interface like other microcontroller boards? So in this article… |

DIY USB Rubber Ducky using ATtiny85 The USB Rubber Ducky or Bad USB is a famous attack tool that looks like a USB pen drive but acts like a keyboard when plugged into any unlocked device. The USB Rubber Ducky allows attackers to program microcontrollers in USB devices to perform various tasks. It can be programmed to inject keystroke and binary files into a system, get the cached password to hack a system… |
