Anime Inspired Holographic Virtual Assistant

November 22, 2022 by 28 Comments

[Jessp] has created a very cute and endearing DIY virtual assistant called Maria. The build combines a 3D printed housing that uses a modern take on the “Pepper’s Ghost” illusion to render a virtual, three-dimensional anime inspired assistant that can take commands to get information about the weather, play music or set timers.

The hub houses a Raspberry Pi 4B and a 3.2 inch LCD HDMI screen mounted flat on its back to render the perspective corrected “Maria” character using a technique borrowed from the Pepper’s Cone project. Polycarbonate sheets are formed into a cone, allowing for the 3D effect of rendering the virtual assistant model. A consumer grade mini USB microphone is used to receive voice commands along with a consumer grade USB speaker for audio feedback. The virtual assistant offloads the text to speech services to Google Cloud, along with using a weather API and Spotify developer account to for its musical options.

All source code is available on [Jessp]’s GitHub page, including build instructions and STL files for the housing. We’ve featured open source voice assistants in the past, including Mycroft and a even a HAL-9000 virtual assistant (running Kalliope) but it’s nice to see further experimentation in this space.

THP Hacker Bio: IamTeknik

[IamTeknik]’s reason for entering his home automation assistant into The Hackaday Prize is simple; we have smart phones, TVs, and even smart cars. Why not a smart house?

Like its namesake from Iron Man, Project Jarvis is an intelligent assistant with a bit of home automation thrown into the mix. The hardware includes the usual relays and door locks, but that’s just the start of it. There’s also a personal digital assistant, living somewhere in the space between the hardware modules and [IamTeknik]’s smartphone. Here, voice recognition, speech synthesis, and a Siri-like functionality is the name of the game. Jarvis is capable of answering questions, compiling reports, reading social network messages, and automating everything connected to the main base station over the Internet.

[IamTeknic] has been busy studying computer systems engineering and of course working on his project for The Hackaday Prize lately, but he was able to sit down and answer a few questions for our THP hacker bio. You can check that out below, along with a few demos of what his personal Jarvis can do.
