We built a desktop companion robot that is powered by Arduino UNO Q. Project is open source: source code, 3D printable files and assembly instructions are available at Arduino Project Hub. Robot is equipped with camera, distance sensor, buzzer, moves head and arms with 3 servo motors and has an animated display. It can recognise objects and respond to it. We build it with idea this should be fun project people can 3D print and build at home themself.

New top story on Hacker News: Show HN: I wrote a custom assembler for CHIP-8 in C++

Show HN: I wrote a custom assembler for CHIP-8 in C++

I'm writing a custom assembler for CHIP-8 and just finished adding support for the DB/.byte directive so I can embed sprites in the ROM and finally get something drawn on the screen. It SHOULD support all OG CHIP-8 instructions, but still a ton of rough edges that I'm ironing out. This is my first ever C++ project, just like the CHIP-8 emulator was my first ever C (and emudev) project. It's so satisfying to write assembly and have your program spit out a ROM that actually runs in the emulator you wrote. All code is written by me (a lot of it livestreaming) as evident by the quality, no AI.
